Tie Tech

TIE is the most efficient products and systems working together What is TIE? TIE is a concept that is at the core of the TimĂłleon philosophy â&#x20AC;&#x201C; ensuring that the complementary technologies we bring together work effectively to achieve lower costs, both environmental and financial, whilst giving the user the comfort they want when they want.

Why is this important? Any particular technology does not stand alone but is affected and influenced by other devices used in the system. A holistic view of the system is needed to ensure that the benefits of using low carbon technologies are realised. And, of course, these technologies must be properly controlled with the ability for the individual to easily alter the comfort conditions to suit. Too often controls are independent, complicated and unintuitive which creates inefficient heating systems that are too hot, too cold or on for too long.

Are renewables the right solution? Timoleon can help select the right choice of renewables for your project. Using our Tonos energy consultancy service we can see if renewables are feasible for your project, providing information on technical feasibility as well as cost paybacks and RHI payments.

Because we supply an integrated whole house package we can guarantee the system will work and reduce costs. Solar Thermal Solar energy can be used for heating. Usually the water collected in spring, autumn and winter is too low to be used by radiators but using a Timóleon underfloor heating system with intelligent control and storage can double the payback compared to a conventional twin coil cylinder or thermal store. See our Solar Thermal section from page 93

Ventilation & Heat Recovery Buildings are becoming increasingly more air tight making the need for controlled mechanical ventilation important. By using a whole house system with heat recovery the incoming fresh air is preheated recovering over 90% of the energy that would otherwise have been lost. See our Ventilation section from page 79

Controls The most crucial part to the TIE system is the Aura control system that brings together the controls for heating domestic hot water and ventilation making the home’s controls easier to install and simpler to use. See our Controls section from page 108

Underfloor Heating Underfloor heating is considered the most comfortable and energy efficient form of heating. Timóleon systems use low water temperatures to further increase the efficiency of air source and ground source heat pumps. For a system that collects the RHI payment using a low water temperature means a greater RHI payment. See our Underfloor Heating section from page 14

Heat Pumps Heat pumps will reduce running costs especially when designed in conjunction with good underfloor heating systems that are designed to work with low water temperatures. Efficient air source or ground source units are available for both domestic and commercial heat pump installations. See our Heat Pump section from page 53

Underfloor Heating

HYDRONIK Underfloor Heating Range

The underfloor heating range from Timóleon.

Many people want underfloor heating simply because it is the most comfortable form of heating, completely unobtrusive, safer and more hygienic than other forms of heating. We understand this and part of our mission is to ensure that we supply the easiest and quickest to install, bestvalue underfloor heating, to suit every form of floor construction used in the UK. But we go much further. Our underfloor heating products have also been designed (and extensively tested) to absolutely minimise the amount of energy a building’s heating system requires in order to provide effective heating, and to make it realistic for this energy to come from renewable sources either straight away or at some stage in the future life of the building.

Two crucial aspects to the design of our products make this possible. The first is our products minimise the temperature of the heating system water required in order to provide effective heating. The lower this water temperature can be, the more efficiently a boiler can run and the more likely it is that water at this temperature can come from a truly renewable source. The second is the speed with which our products respond to changes in heating power demand. Timóleon products for timber floors have been designed with low thermal mass and this enables them to respond very quickly and efficiently to changes in heating demand.

Underfloor Heating

How does it work? Underfloor heating works by circulating warm water through pipe embedded within the floor construction. Heat from the pipe is transferred into the floor and then into the room providing enough warmth to heat the building all year round. This removes the need for radiators making more effective use of the space as well as eliminating any high temperature surfaces - an underfloor heating system generally has a surface temperature between 25Â°C and 27Â°C, lower than the palm of your hand. A conventional radiator can be as hot as 75Ë&#x161;C. The way in which underfloor heating transfers heat is also different to a radiator. Radiators transfer energy principally by convection, heating the air above and around the radiator causing the air to rise. As the warmed air is more buoyant than the cooler air in the room it will rise to the ceiling. The warmed air, as it crosses the ceiling, will begin to cool and then fall. This motion creates a convective current with higher air temperatures nearer the ceiling than the floor. An underfloor heating system predominantly transfers radiant energy. Compared to radiators, a room with underfloor heating will have a higher radiant temperature with less temperature stratification, draughts and dust movements. This is why underfloor heating is considered the most comfortable form of heating.

Using Timóleon timber underfloor heating systems improves the SAP rating.

We make sure our systems work well in every construction, including timber floors We draw on years of experience to develop and manufacture systems that are easily installed into timber constructions such as suspended, batten or floating floors. However getting underfloor heating to work effectively in timber floors is not straightforward. Timber is not naturally a good conductor of heat. This means, for certain types of underfloor heating, using high temperature water is the only way the system will be able to heat the room effectively and as a result the efficiency of the heat pump or boiler will be reduced. We are specialists in manufacturing UFH products for timber floors and have developed a range that works well at low water temperatures. Our systems are also designed to avoid squeaky floors, whilst maintaining or improving the strength and acoustic qualities of the floor.

Get the best SAP result with timber underfloor heating. SAP, used to determine the energy rating for Building regulations, recognises that underfloor heating is energy efficient. Using underfloor heating with a heat pump improves the SAP rating when compared to using a heat pump with radiators. If underfloor heating is installed within a timber “dry” floor the rating is improved even further as it has a faster warm-up time than an in-screed underfloor heating system.

Underfloor Heating

Underfloor heating, heat pumps and the Renewable Heat Incentive. The domestic Renewable Heat Incentive (RHI) is now available as a payment for using renewable energy heat sources. This payment is linked to the calculated energy consumption of the property. As heat pumps use electricity to generate heat the RHI is only paid on the renewable component of the building heat load and this is dependent on the efficiency of the heat pump. An efficient heat pump and low water temperature emitter will use less electricity and the renewable component will be higher and therefore the RHI payment will be higher. The efficiency (Seasonal Performance Factor â&#x20AC;&#x201C; SPF) of the heat pump is solely determined by the water temperature needed by the emitter at the design conditions. If high temperature water is needed then the payment is reduced or is zero. See below the tables for SPF vs water temperature.

This makes choosing the right underfloor heating system important Not only will a system designed to work at low temperatures reduce running costs but also will benefit from increased RHI payments. The Hydronik range of underfloor heating products from TimĂłleon are designed to minimise the temperature of the water needed for your project.

Underfloor Heating

Not all underfloor heating systems are the same.

If a heating system has to run at high water temperatures the heat source will be less efficient. All Timóleon products are designed to use low water temperatures, saving energy and money.

Saving 33%

To ensure good performance at low water temperatures it is crucial that there is a conductive pathway that transfers heat quickly from the pipe to the floor surface. If there is a break in the conductive pathway i.e. an air gap, then the efficiency of this energy transfer is greatly reduced. To overcome this inefficiency the water used in the heating system needs to be much hotter to produce an effective heat output.

Underfloor Heating

Our products are perfectly suited to using heat pumps and other renewable energy sources. To be able to work with these technologies a heating system must be able to run at low water temperatures yet still provide sufficient heating to warm the building particularly in timber floors. This is important because a heat pump producing lower temperature water will reduce running costs and carbon emissions.

In independent tests at BSRIA, systems that have an air gap between the pipe and floor deck are less efficient at transferring energy than Tim贸leon systems. This means they have to use water significantly warmer to produce the same heat output.

Choosing ToronFloor from Timoleon can reduce energy bills by over 30%

Did you know?

The 730kg of CO2 saved per year with Tim贸leon ToronFloor is equivalent to driving 5,000 miles in a family car.

Consumption based on a new build 4 bedroom 200m2 property using a ground source heat pump and heating system as shown.

Underfloor Heating

Choose an underfloor heating system that has been tested for use at low water temperatures. With any heating system the larger the area of the emitter the cooler the surface temperature needs to be to achieve the same heating effect. This is why underfloor heating runs at a much lower water temperature compared to radiator systems. Studies have demonstrated that using underfloor heating rather than radiators with a ground source heat pump can make the heating system up to 30% more efficient. Our products are independently tested at BSRIA for heat output. This enables us to accurately compare the output of the underfloor heating system with the heat losses of the building to ensure that the system will work as specified. This is provided that the underfloor heating system is designed to run at low temperatures. Tim贸leon products are designed to do just that.

Designed to be future proof. It is important that any heating system should be designed with the future in mind. If you install a heating system which depends on high water temperatures it is impractical to change in the future to a heat source which provides water at low temperatures typical from renewables. Every heating system should now be designed to enable the homeowner to retrofit renewable technologies in the future. This means designing the system for the lowest possible water temperature.

Tim贸leon systems have been independently tested for performance.

Underfloor Heating

HYDRONIK Underfloor Heating Range

What do you need? 1. The Emitter

3. Controls

The emitter consists of pipe set within either a screed or timber floor. It should provide effective heating when covered with commonly-used floor finishes, while using low water temperatures. It should be designed to be effective at transferring energy between the pipe and the floor surface.

Good controls are essential for any heating system. Room temperatures should remain comfortable and the heating system should only be on when needed. Underfloor heating systems do not use thermostatic radiator valves so all temperature control is done by thermostats situated within each room. Using thermostats improves efficiency and comfort conditions.

2. The Manifold

4. Heat source

The manifold distributes water from the primary heating system into the individual underfloor heating circuits. For ease of installation the manifold is best positioned in a central location. Manifolds may be fitted with a water mixing valve and secondary circulator wherever high temperature primary water needs to be reduced to the low water temperature needed by an underfloor heating system.

This supplies the warm water needed. It could be a boiler or any of the renewable energy alternatives. The higher the water temperature required by the emitter, the lower its efficiency will be.

Underfloor Heating

HYDRONIK Underfloor Heating Range

Underfloor Heating Product Range Suspended Floors Timber suspended floors use joists to support the floor deck. The underfloor heating system can either sit between the joists or within the floor deck itself.

Battened Floors A batten floor is a conventional way of installing a timber floor over a solid subfloor. The underfloor heating system within the batten space must be in contact with the floor deck to provide good thermal performance. Floating Floors A floating floor consists of a floor deck supported on a continuous layer, usually insulation, that is not fixed directly to the subfloor. With any floating floor it is important to use insulation that has the appropriate compressive strength for the intended floor loads. Screeded & Concrete Floors

The use of underfloor heating in screeds is common place. Care should be taken not to damage the pipe when the screed is laid.

Raised Access Floors A raised access floor is used to create a space under the floor so that other services can be easily routed through the building.

Acoustic & Resilient Floors In a separating floor there is a requirement to use a construction that reduces the transfer of sound. There are standard constructions referred to as Robust Details which, when followed exactly, ensure compliance with Part E of the Building Regulations. Recommended for Heat Pumps These products have been designed to work at low water temperatures improving the efficiency of the heat pump. A more efficient heat pump reduces running costs and increases any qualifying RHI payment. Refurbishments Our products can be used in a diverse number of floor constructions however these products are suitable for refurbishments as they are either made from materials that would be used in the construction or have a very low build-up suitable for an existing floor.

ToronFloor panels are manufactured from flooring grade chipboard or plywood. The pre-machined panels are routed with a unique pattern to accept 12mm pipe. The design of the panel makes it suitable as a structural floor deck. The panels are laid and fixed onto the joists in the same way as a normal chipboard floor. The pipe is installed into the grooves with the ends of the circuit dropping into the joist space to then continue to the manifold. With the pipe installed the pre-glued Toron covering layer is then applied to complete the floor.

Introducing the TORON2 panel Second generation ToronFloor The ToronFloor panel has been further developed making it one of the easiest-to-install underfloor heating systems on the market with exceptional heat output. Manufactured by Tim贸leon in our factory in Exeter the TORON2 panel is now supplied with the aluminium diffuser pre-bonded to the Toron panel making the installation even faster. In addition Tim贸leon can supply the 6mm covering layer with a peel-off adhesive layer removing the need for PVA to glue the 6mm ply layer down. ToronFloor has an excellent heat output improved by the developments to the Toron panel. As the pipe is embedded within the surface of the floor deck there is an excellent transfer of heat. This provides a high output even at low water temperatures making the system ideal for use with heat pumps and other renewable energy sources. The ToronFloor heating system has been independently tested at TRADA for structural performance.

The LowBoard panel enables underfloor heating to be installed where there is minimal height available to build up the floor. The total height of the panel is just 15mm. The LowBoard panel is a high density wood board with grooves routed to accept the 12mm pipe. The panel has an aluminium layer bonded to the underside that acts to spread the heat through the board and into the floor. The panels are laid as a floating floor over the existing construction with a ply layer or the floor finish laid over to complete the floor. LowBoard is also available in 22mm thick panels for 16mm pipe. LowBoard 22 is used for larger areas where longer pipe runs are required.

LowBoard is the only multidirectional low build-up panel. TM

The 15mm LowBoard TM panels has pre-routed channels that enable the panel to be simply laid across the whole floor without trying to configure loop and straight panels which can be particularly difficult in non-rectangular rooms or where there are obstructions in the floor such as kitchen islands or sanitary ware. Having this unique multi-directional design speeds up installation and reduces the complexity of the installation by having one simple panel installed throughout. As all the loops are within the panel there is no need to have plastic end loops or use a liquid screed to complete the floor. The LowBoard TM panel takes care of it all.

The ClipPlate Compact panel is designed for refurbishment applications. The panel is 14mm thick and uses 12mm pipe making it a much thinner panel. The panel comes with holes within it to allow the screed to flow within the panel. The plate has an adhesive layer on the underside that ensures the plate stays in place when the screed is being poured.

INSTALL GUIDE

OgeeBoard is manufactured from XPS polystyrene insulation and can replace the insulation needed to comply with building regulations. The polystyrene boards are routed with channels into which the pipe is installed. With the pipe installed a screed is laid over. The OgeeBoard insulation panels are designed to hold the pipe within the thickness of the insulation reducing the possibility of damage from site traffic. No other fixings, staples or plates are needed to hold the underfloor heating pipe in place. The OgeeBoard insulation panels are available in any thickness from 35mm enabling very fast installation of the screed underfloor heating, with assured pipe centres.

Underfloor Heating

Save Screed. Save Time. Save Money. OgeeBoard is an underfloor heating plate made entirely from extruded polystyrene insulation. When used instead of alternative pipe-in-screed system the product will improve the U-value and minimise the thickness of the screed needed thereby improving the drying time and reducing the installation costs. The structural part of any concrete screed is that above the underfloor heating pipe and this should be a minimum of 25mm. In addition the screed thickness for a domestic application should be 65mm (75mm for an industrial application). From the diagrams below it can be shown that using OgeeBoard reduces the amount of screed needed as more of the area between the pipes is taken by insulation.

Acoustic Floor Constructions

What is an Acoustic Floor Construction? Timóleon underfloor heating systems are ideally suited for incorporation into acoustic constructions, both in residential and commercial applications. Part E of the Building Regulations shows how such constructions must provide resistance to the passage of sound. Compliance with the performance standards is demonstrated by passing a pre-completion test (PCT) for each individual construction. However PCTs can be avoided if a Robust Standard Detail (RSD) is adopted. Specific RSDs have been established for each construction and underfloor heating can be incorporated into an RSD construction provided:

Acoustic insulation in a floor is important to reduce the transfer of sound.

ROOM A

• That no fixings or staples penetrate or break the separating resilient layer used in a construction. • In a floating floor treatment the underfloor heating does not connect the structural floor with any of the floating floor elements thereby bridging the resilient layer.

ROOM B

There are a variety of RSD constructions and it is important to understand how effective the underfloor heating system will be when used with these constructions. In our guide to underfloor heating and acoustic constructions (TX 100) we show how underfloor heating can be simply incorporated. Acoustic constructions are commonly found in residential buildings with floors, walls and ceilings that separate living spaces. These constructions are required to provide resistance to the passage of sound allowing occupants to enjoy quiet living conditions without being disturbed by those living in adjacent properties. Such buildings can benefit enormously from underfloor heating, not only to enhance the living environment but also to improve energy efficiency.

Underfloor Heating

Our acoustic range of products are ideally suited for both residential & commercial applications. Batten Floors - AB Plate Batten systems with a resilient layer can be used in timber and concrete suspended floors. These are termed as floating floor treatments. The batten moves up and down due to the resilient layer so it is important the underfloor heating system moves with the batten to maintain contact with the floor deck. The AB plate is installed directly over the acoustic battens. The product is designed to allow the installer to walk between plates. The AB plates have a pre-bonded insulation layer which improves the thermal transfer into the floor deck.

Suspended floors â&#x20AC;&#x201C; ToronFloor RdB Introducing acoustic insulation into an existing suspended floor is difficult without increasing the floor heights dramatically. The ToronFloor RdB system is an additionall 17mm over the standard ToronFloor product. This small increase in height provides a significant improvement in the sound deadening properties of the floor. The ToronFloor RdB panel is manufactured in the same way as 22mm standard Toron floor but with two additional layers, a second chipboard layer and a resilient felt layer.

Screeded Floors - OgeeBoard Underfloor heating systems used within a screed floor must not penetrate the resilient layer (i.e. using fixings such as staples) and must avoid bridging the screed to the slab. The OgeeBoard system does not require any fixings or staples. This ensures the acoustic layer isnâ&#x20AC;&#x2122;t punctured when the pipe is being laid. The OgeeBoard product is made from insulation improving the thermal performance.

Underfloor Heating

Surface cooling

A low energy alternative to air conditioning. Cool water can be used in the underfloor heating system to provide room cooling as an alternative to airconditioning. It is also possible to chill the ceiling or wall to get the same effect. This method of cooling is called Surface Cooling.

Performance Surface cooling is able to provide comfort cooling to most commercial applications with outputs up to 70W/m2 for a ceiling system and 50W/m2 for a floor system. A surface cooling system will reduce the sensible loads in a space. It may be necessary, in humid conditions, to provide dehumidification. Dehumidifying a space also has the benefit of reducing the dew point (which limits surface temperature and therefore output) and increasing the cooling capability of the system.

Cool, not cold Chilled water is provided by either a ground source or air source heat pump. A surface cooling system requires water at a higher temperature than that needed by an air conditioning system. This increases the efficiency of the air source heat pump. Where ground loops are installed the benefits are even greater. During the summer the ground temperature will be around 15째C at a depth of 2 metres. When coupled with a heat exchanger this chilled water can be used directly in the surface cooling system, making it almost free to run, with the benefit of recharging the ground, storing the unwanted heat energy until needed by the heat pump.

Our FoilBoard Ceiling system can be used in suspended grid ceiling applications in newly built and existing buildings. It is particularly suited to use in retrofit commercial applications. The system is modified by having pipe pre-installed into the panel. The modular panel is then installed above a standard 600mm x 600mm ceiling tile. Once the panels are in place the tails of each module are connected in series to create an underfloor heating circuit. Unlike an underfloor heating system there are no floor finishes to reduce the flow of heat to the surface, so water temperatures can be lower to achieve the same output, making heat sources such as heat pumps more efficient than even underfloor heating systems.

Underfloor Heating

Creating comfortable working environments that save on energy usage when compared with air conditioning. Surface cooling vs air-conditioning Air conditioning is responsible for 10% of the energy used in commercial buildings. Using surface cooling can significantly reduce energy consumption whilst provide a comfortable working environment. The transfer of energy in a surface cooling system is mostly done by radiant heat exchange, approximately 80%. The absorbing surface, a floor, wall or ceiling is cooled to a temperature lower than the items and occupants within a room. This cooled surface will then absorb energy from within the room. In reducing the radiant temperature the occupants feel more comfortable even though the air temperature has only slightly changed. This effect is analogous to a church or cave where the walls and floor are at a lower temperature than the air making the space feel cooler. Air conditioning works in a different way, mechanically forcing air over cooling elements thereby cooling the air in the room but not significantly reducing the radiant temperature. This results in extremes of radiant and air temperature being created. Big differences between air and radiant temperature creates discomfort, experienced by anyone who sits near both a south facing window and an air-conditioning unit on a hot summerâ&#x20AC;&#x2122;s day. Surface cooling creates an environment where the air and radiant temperatures are closer together which, with the absence of noise and air movement from an air conditioning unit makes for a more comfortable working environment.

Ceilings & walls

Heating in ceilings and walls

1. Underfloor Heating

2. Warm air heating

3. Radiator Heating

4. Ceiling Heating

The same principle that makes underfloor heating work can be applied to walls and ceilings. As long as there is sufficient heating area a room can be satisfactorily warmed with a ceiling or wall heating system giving the same comfortable radiant effect as underfloor heating. The heat output of ceiling and wall systems tend not to be restricted by floor finishes in the same way as an underfloor heating system and can therefore work at even lower water temperatures with the resulting surface temperature being around 30Ë&#x161;C. The temperature profile of a ceiling heating system is very similar to an underfloor heating system and therefore creates similar levels of comfort. The surface temperature of the ceiling system should be no more than 30oC to avoid temperature asymmetry which could reduce comfort levels. In comparison a warm air system creates significant temperature stratification with high temperatures near the ceiling and low temperatures near the floor, not only does this feel uncomfortable but inefficient, especially in rooms with high ceilings.

Timóleon uses high quality PE-RT underfloor heating pipes. The five-layer structure achieves a high degree of oxygen tightness and ensures that this is retained even under rough building site conditions. The entire range is backed by decades of experience in plastics processing. A specially modified polyethylene of medium density is used for underfloor heating systems using PE-RT pipe, the molecular structure and composition of which ensures very good thermal stability and a high degree of mechanical strength. The five-layer pipe structure is manufactured by means of extrusion in one single process. The EVOH layer provides a very good oxygen barrier while the outer PE-RT layer protects the entire structure against damage. Only the best material qualitiy from renowned manufacturers are used.

Underfloor Heating

UFH FAQs: Floor Finishes The best floor coverings to work with underfloor heating systems are typically those with low thermal resistance.

All types of floor finish can be used with underfloor heating providing the resistance of the finish is considered. A highly resistive floor finish will slow the flow of heat into the room. Typical floor finishes such as timber and carpet are regularly used with underfloor heating. Some finish manufacturers stipulate maximum surface temperatures. Underfloor heating has a floor surface temperature of approximately 26°C for most applications however some systems where the building heat loss is high will have surface temperatures up to 29°C. Underfloor heating systems should not be designed to operate at floor surface temperatures higher than 29°C. If your intended finish is greater than 1.5 Tog then please call us and we will check the performance of the underfloor heating.

Timber Floors

Linoleum & vinyl tiles or sheet

Timóleon has long experience of how good UFH is the best way of caring for a hardwood floor. Timber changes dimension due to changes in its moisture content, and this varies naturally throughout the year. The important issue is to keep the moisture content of the upper and lower surfaces of the timber the same. If they do, the timber floor will stay perfectly flat. If they don’t, it will crown or cup.

It is important to ensure that when laying this product over a concrete subfloor that the subfloor is completely dry otherwise bubbling may occur. The relative humidity of the subfloor should be no more than 75% (measured as specified in BS 8201).

The first key is to lay the timber floor with moisture content 8-10%. The second is to ensure the UFH turns on gradually at the beginning of each heating season, which can be assured by using programmable room thermostats and leaving the heating on. The heating will then run briefly, and only as necessary, allowing time for absorbed moisture to naturally respire into the room.

Ceramic & Stone

These materials have a low thermal resistance that makes them very suitable for underfloor heating. Consideration must be given to expansion gaps and the suitability of adhesives used to bond the tiles to the subfloor.

Carpet

Our general advice is to avoid carpets and underlay having thermal resistance greater than 1.5 Tog. However, tests carried out at BSRIA on 24 different combinations showed that some with higher published resistance than this work well over UFH. Timóleon understands the results of these tests, which measured the difference between Published Tog and Effective Tog, and can advise accordingly.

Underfloor Heating

UFH FAQs: Concrete Screeds There are many different types of screed from the conventional sand/cement screed to proprietary liquid screeds. The screeds that are discussed here are floating screeds i.e. they are not bonded to the concrete subfloor. Sand/cement screeds – The minimum thickness of a floating screed is 75mm for commercial installations and 65mm for domestic installations. There should be a minimum of 25mm screed over the pipes (BS8204-1). Calcium sulphate and anhydrite screeds – The benefit of using this type of screed is that the drying time is less than conventional sand/cement screeds and there is less shrinkage. The minimum thickness of a screed in a commercial installation is 40mm and 35mm in a domestic installation. There should be a minimum of 25mm screed over the pipes (BS8204-7). Pumpable self-smoothing screeds – There are many proprietary screeds on the market. Advice should always be sought from the manufacturer.

Laying screeds in Underfloor Heating BS 8204 part 2 provides details on spacing and positioning of joints within a concrete screed. The British Standard for underfloor heating, BS 1264 part 4, states that there should be joints in stone and ceramic finished screeds every 40m2, with a maximum length of 8m between joints. A joint must be placed at least every 8m across the floor but as the joint is only one third of the screed thickness it should not interfere with the underfloor heating pipe provided the underfloor heating circuit has been fixed down securely. Only flow and return pipe should pass through movement joints. Where this happens a 300mm piece of conduit should enclose the pipe and span the joint.

Drying of screeds As a rule of thumb a 50mm sand/ cement screed could be expected to dry in good conditions within 2 months and a 75mm screed around 3 months. BS 1264-4 states that sand cement screeds should not be heated for at least 21 days after laying and with anhydrite screeds 7 days after laying. The screed manufacturer’s instructions must always be followed.

must not get any warmer than 25˚C for the first 3 days or 15˚C above the temperature of the unheated floor. After this period the system can be switched to the maximum temperature and kept there for 4 days. The underfloor heating must never be used to dry the screed. It is important that the screed must be allowed to cool to room temperature before the final floor finish is laid.

Once the screed has dried the system can be turned on but the screed

Underfloor Heating Performance

Underfloor heating heat outputs

Underfloor heating systems can be designed to react very quickly to heating demands. The warm-up time of the system depends upon several factors.

The underfloor heating heat output is based on a number of variables:

The time taken for the underfloor heating system to emit heat is dependent on the characteristics of the floor in terms of the construction, pipe centres and the floor finish and also the temperature of the water used in the underfloor heating system. Underfloor heating with pipe embedded in a thick concrete slab will have a longer warm up time than dry construction systems such as those used in suspended, batten or floating floors. This is recognised in SAP with timber floor underfloor heating having a better overall SAP rating than concrete underfloor heating. The room warm-up time is also dependent on the heat loss of the building. The underfloor heating system must be sized to overcome the heat losses of the building but also have additional capacity to ensure a good response time from cold.

Underfloor heating running costs The cost of running an underfloor heating system depends on the heat loss of the house, how often the heating system is running, the cost of the fuel or electricity and the type of heat source. So it is difficult to predict running costs although studies have shown that heating systems using low water temperatures will be the most efficient and have the lowest running costs. Underfloor heating, as it is a large surface area emitter, will run at the lowest water temperatures.

Floor finish - floor finishes have different thermal resistances. Tiles for example are very conductive whilst a combination of carpet and underlay is less conductive. Also, the thicker the material the lower the heat output will be. Water temperature – the higher the mean water temperature (the average between flow and return temperature) the higher the heat output. The underfloor heating product and the construction it is put into – Timóleon products are designed to have a strong conductive pathway from pipe to the floor surface. Some products have an air gap which reduces the heat output. Timóleon has tested its systems at BSRIA and is able to provide information on the heat output for your specified construction.

Underfloor Heating

UFH Maintenance Maintenance of the underfloor heating system is straightforward. There is no specific maintenance required for the heating system other than that needed for the boiler or heat pump. The circulator, actuator valve and mixing valve are the only moving parts and these are designed for continuous operation over many years.

Guarantees Tim贸leon has a strict policy of quality control in all aspects of its business from design to product manufacture. We adhere to the British Standards where they apply to the designs, products or systems that Tim贸leon manufactures and produces. Tim贸leon systems have been tested for performance with BSRIA and TRADA where appropriate.

UFH Design It is important that the there is an underfloor heating design showing where the pipe is in the floor, how close the pipe is together and what product is being used as the heat emitter. For simple systems the design can be produced by the installer and does not need to be a formal CAD drawing. However Tim贸leon provides a full design service for all orders showing where the pipe and product sits in the floor along with the balancing settings for the installer to commission the system.

Go green, and save money at the same time.

Heat Pumps can be up to five times more efficient than fossil fuel systems saving money on the running costs and reducing the associated greenhouse emissions. Heat pumps can also benefit from the Governmentâ&#x20AC;&#x2122;s renewable Heat Incentive (RHI) which is a guaranteed payment on the amount of renewable energy produced for seven years (domestic) and twenty years (commercial). The RHI makes installing a heat pump economic sense with faster payback so the user can benefit from lower running costs sooner.

Why from Timóleon? We provide extensive support for our heat pump range. As standard we offer free use of our remote access software – AlphaWeb –this enables the end-user to interact with the heat pump whilst away from the home or office as well as providing diagnostic information to the installer or for us at Timoleon. This is part of our “Monitor and Maintain” service package. We believe that for a system to be efficient and trouble free it needs to be properly commissioned. For every heat pump from Timóleon an engineer will attend site to commission and start-up each unit. At the same time the engineer will check the system and make sure it is connected to Alpha-Web. Following commissioning we will provide our GOLD “Monitor and Maintain” service free for a year on top of the 5 year parts warranty from Alpha-Innotec. Our GOLD service is total peace of mind. Not only do we proactively remote monitor reporting and issues before they are even evident but we will provide all labour and parts free of charge. The Gold service also includes the annual service and system check not only of the heat pump but will also include the Timoleon underfloor heating system if one has been used in conjunction with the heat pump. After the first year Timóleon provides a SILVER or BRONZE service package depending on the level or cover the end-user requires. The Bronze package is standard on all heat pumps will sell during the warranty period.

What is a heat pump and how does it work? A heat pump can produce 3 to 5 kiloWatts of heat from only a single kiloWatt of electricity. The heat pump takes heat from the surroundings such as the air or ground even at sub-zero temperatures and increases the temperature so that it can be used in the heating and hot water system. The energy taken from the surrounding air or ground is then replaced by energy from the sun.

Heat is absorbed by low pressure liquid refrigerant in the evaporator. The refrigerant then evaporates.

The refrigerant gas is then compressed raising its temperature.

The hot refrigerant gas passes into a heat exchanger where the heat transfers into the heating and hot water system. The hot refrigerant gas condenses as it cools.

The high pressure liquid refrigerant passes though an expansion valve where the pressure is reduced. The low pressure liquid refrigerant enters the evaporator and the process starts again.

Heat Pumps

Efficiency Heat pumps are considered a renewable technology as they are able to convert 1kW of electricity into 3 to 5kW of heat. The ratio of electrical consumption to heat generated is known as CoP (coefficient of performance) and varies depending on the operating conditions as described below. The average efficiency (CoP) of the heat pump over the year is called the Seasonal Performance Factor (SPF) and is important in determining the RHI payment. A heat pump becomes more efficient (uses less electricity) as the heat source (the air or ground) gets warmer. Also, the efficiency is affected by the water temperature produced by the heat pump - the hotter the water produced the less efficient the heat pump will be. That is why low temperature underfloor heating is well suited to heat pump technology.

= Running costs

The running costs of a heat pump will of course depend on the heat loss of the building in the same way as a conventional boiler would. In addition the efficiency is improved and the running costs reduced with a low temperature heat emitter such as underfloor heating.

Heat Pumps

Renewable Heat Incentive (RHI) The domestic RHI is available on MCS accredited heat pumps. The RHI is available for seven years. The rate payable is dependent on the efficiency of the system, specifically the water temperature needed by the heat emitter. The commercial RHI is provided for 20 years but, unlike the domestic scheme, requires the installation to be heat metered at source. Unlike the domestic RHI it is not dependent on the required water temperature of the emitter, however for ground source heat pumps there are two payment tiers designed to avoid over consumption. To be able to claim the RHI it is necessary to provide room by room heat loss calculations (as detailed in document MIS 3005) and to then demonstrate that the chosen heat emitter will meet those losses. The heat emitter flow water temperature required to meet these losses will then influence the domestic RHI payment. RHI is not available for an air source heat pump operating with a flow water temperature above 50oC. Timoleon provides an energy consultancy service – Tonos – that can provide all the required heat loss and heat emitter calculations required to comply. The RHI rate is inflation linked. The current rates are shown below.

The Lux controller is installed inside and wired to the heat pump using pre-fabricated cable and plugs. Although it is not mandatory Timoleon always specifies a buffer tank to protect the heat pump and prolong the life of the compressor.

Heat Pumps

System overview

How it works An air source heat pump extracts the energy from the outside air. The energy in the air is inexhaustible and always available making the system renewable although some electricity is needed to run the heat pump. An air source heat pumps has the advantage of being cheaper to install than a ground source heat pump although a ground source heat pump will be more efficient due to the stable ground temperature and as a result have lower running costs. The domestic range of air source heat pumps from Alpha-InnoTec are efficient, precision engineered units that are straight-forward to install. All the units have had the evaporators coated with corrosion protectionessential for the UK maritime climate.

Heat Pumps

LWD70A/SX The LWD 70A/SX is the latest in heat pump technology. The 230V heat pump is mounted externally with an internal hydraulic module that contains the expansion vessel, back up heater, heating circulator and safety module. The LWD is extremely quiet at only 45dB at 1m and has impressive efficiencies even at low outside air temperatures – CoP of 4.35 at A7/W35. As with all the MCS approved domestic range available from Timóleon the evaporators have corrosion protection, an important feature in a maritime climate such as the UK. If two heat pumps are needed in cascade the internal HMD hydraulic module is able to provide the necessary control without the need for a second controller. The LWD 70A/SX is MCS approved (listed under “ait-deutschland GmbH”).

The heat pump is installed internally with an external ground array, either horizontal or vertical. Horizontal arrays consist of pipe installed in trenches dug up to 1.2m deep. Alternatively bore holes can be drilled and a vertical pipe installation used, this method requires less land area but drilling bore holes is more expensive than excavating trenches for horizontal pipe arrays. It is usual for the pipe work used in the ground collectors to be connected to a common manifold with a single flow and return connection to the heat pump.

Heat Pumps

System overview

How it works Rather than absorbing energy directly from the air, a ground source heat pump uses pipe buried in the earth to take energy from the ground. The temperatures in the ground do not vary to the same degree as air temperatures. The higher more stable temperatures in the ground mean heat pumps that use ground arrays are more efficient. When designing the ground loops it is necessary to consider the soil type and level of water saturation as this effects the conductivity of the ground and therefore the transfer of energy from the ground to the pipe.

Commercial Heat Pumps Providing heat for residential, commercial and industrial properties accounts for a considerable part of all energy consumption in the UK. Using heat pumps as an alternative to conventional heat sources in commercial buildings can make a significant contribution to the UK’s carbon reduction target as well as providing significant economic benefit to the user. Both ground source and air source heat pumps are supported by the Government’s commercial RHI scheme than provides payments for 20 years. Below are the comparisons in cash benefit between air source, ground source and biomass compared to conventional mains gas and direct electric heating systems. The cash benefit from RHI and running costs are shown for the 20 year period at Net Present Value. The actual cash benefit will be greater due to inflationary increases in fuel costs and the RHI payment. The capital cost, maintenance and product lifetime need to be factored in to calculate the return on investment.

All of which can used in cascade to satisfy much higher loads. Alpha-InnoTec heat pumps come with AlphaWeb remote access for remote diagnostics, troubleshooting and worldwide control. The Lux controller, which is standard on all heat pump types, is BACnet compatible and can output data logs via the USB port.

Heat Pumps

LW Air Source Heat Pump The LW range of air source heat pumps are available up to 31kW. These can be used in cascade to form much larger installations. All the heat pumps listed below are 3-phase. The LW can be controlled remotely using AlphaWeb as well as being controlled by the building management system. If the installation is larger than 45kW then it may be eligible for the commercial RHI. If the installation is larger than 45kW then MCS isn’t required however it is necessary to provide a calculation methodology to demonstrate that the heat pump has been sized correctly. Timóleon provides an energy consultancy service – Tonos – that can provide all the required heat loss and heat emitter calculations required to comply.

Ventilation & Heat Recovery

Reduce energy consumption and improve the air quality with whole house ventilation.

Whole house ventilation provides a controlled way of introducing fresh air into the building removing the need for trickle vents above windows or opening windows at night. The system also extracts the damp stale air from kitchens and bathrooms. This outgoing air is warm and this energy in a normal mechanical ventilation system would be lost outside. The Heat Recovery Unit has an integrated heat exchanger that transfers the energy from the outgoing air to the cold incoming air thereby minimising the heat loss due to the mechanical ventilation.

Ventilation & Heat Recovery

What is MVHR and how does it work? A Mechanical Ventilation and Heat Recovery (MVHR) system extracts the stale humid air from wet rooms in the same way as conventional mechanical ventilation but instead of dumping the warm air outside the air is moved through internal ducting to a central Heat Recovery Unit (HRU) located in the loft or in a cupboard. The HRU passes the outgoing air through the heat exchanger whilst simultaneously drawing fresh air from outside in the opposite direction. This process recovers up to 90% of the heat that would otherwise be lost whilst supplying fresh air in a controlled way throughout the building. By extracting the damp air from bathrooms and kitchens condensation problems are reduced as well as mould growth and the build-up of pollutants. In addition the living environment is improved as windows do not need to be left open reducing noise, pollution and potential security issues.

1. Outside fresh air Outside air is drawn into the house through a roof cowl or air brick.

2. Transfer through HRU The heat recovery unit transfers the energy from the outgoing warm stale air into the incoming cold fresh air.

3. Extracted air Air is extracted to the outside though a roof cowl or air brick.

4. Supply to bedrooms & living areas The heat recovery unit supplies fresh air through ducting into living rooms and bedrooms through valves in the ceiling.

5. Extraction from bathrooms & kitchens Stale humid air is extracted by the heat recovery unit from bathrooms and kitchens through valves in the ceiling.

Ventilation & Heat Recovery 82

Create the perfect environment by removing stale air and replacing it with fresh outside air.

• Moisture that causes mould growth is removed. Mould growth and other pollutants lead to poor indoor air quality. • Less condensation on windows • Provides better indoor climate • A controlled supply of fresh air • Windows do not need to be left open eliminating noise, pollution and security issues

Ventilation & Heat Recovery

Key benefits of MVHR Systems

• Eliminates noise from extract fans located within bathrooms • Low maintenance • Less dust

Introducing fresh air into a house and extracting the stale air is essential to maintain comfort levels, to alleviate the potential build-up of contaminants and to reduce humidity in bathrooms and kitchens. Part F of the building regulations makes it mandatory for new homes to be properly ventilated. Mechanical extracts are usually installed to remove stale and humid air from bathrooms and kitchens. However the energy present in the warm air is lost when extracted outside, the heating system is then needed to reheat the incoming air. The transfer of energy from the outgoing stale humid air to the incoming fresh air reduces the need for the heating system to re-heat the air. This saves energy and reduces the running costs of the heating system.

Heat from ventilation loss is the single biggest component of energy loss in a modern building especially in Passive house design. This is because, no matter how air tight the building is, fresh air is always required and this needs to be heated. This supply of fresh air is conventionally provided by extracting stale air using mechanical ventilation from bathrooms and kitchens with fresh air coming from window vents in other rooms. The heat loss from mechanical ventilation can be significantly reduced by using MVHR to control and recover the energy that would otherwise be lost.

Ventilation & Heat Recovery

Timóleon MVHR systems have boost and automatic summer bypass control. Does the system run all the time, and all year round? Yes, the system constantly runs moving air at a low volume in and out of the building. The system will only operate on “boost” when activated usually by switching a bathroom light on.

What is the running cost of an MVHR system? The electricity consumed by the MVHR system is very low and this is easily offset by the heat energy saving. The running cost will vary but is in the region of 25p to 30p/day.

What will happen if there is no power? If the MVHR system should stop operating over several hours you will begin to notice the room becoming stuffier especially in bathrooms however there is no risk to health.

Is it noisy? In continuous mode the HRU is barely audible. In boost mode because of the extra volume extracted the noise is increased slightly. The system is designed to oporate at 66% of the HRU capacity to reduce noise.

MVHR Product Characteristic Data Base (PCDB) SAP is the Government Standard Assessment Procedure for the energy rating of dwellings. PCDB enables performance of new technologies including MVHR to be used in SAP calculations. Our MVHR appliances are >92% efficient and easily satisfy the requirements of SAP Appendix Q. To achieve the highest Code for Sustainable Homes level, a SAP heat loss parameter (HLP) of 0.8W/m2K is required. This will not be achievable without MVHR. Our integrated systems help our customers to achieve higher levels of the Code for Sustainable Homes and the best possible SAP ratings.

For passive house design Passive house is becoming more wide spread as a concept, and is perceived as the pinnacle of energy efficiency building design and practice. This building standard requires high levels of insulation and air-tightness to achieve this certification. It also requires a passive house certified MVHR system to be installed with a pre-heat to stop the heat exchanger freezing. On the CA350PH the pre-heater is installed within the MVHR unit, the HRU requires an external pre-heater to be installed on the fresh air intake. Timóleon have the technical expertise and understanding of the principles of passive house MVHR design, which will enable you to meet this standard.

Ventilation & Heat Recovery

How does MVHR work? 1. A Roof Cowl is used for passing ductwork through a roof, for extract or supply. 2. The rigid insulated duct runs from the Heat Recovery Unit to the manifold. Its insulating properties prevent condensation and limit the escape of heat and noise, reducing the requirement for silencers. The installed ductwork can be supplied to meet NHBC Standards. 3. A double airbrick and adaptor is used as a terminal fitting at an external wall, for extract or supply. 4. The Heat Recovery Unit uses fans to extract air from inside the building and also introduce air from outside. The two air flows pass through a high efficiency heat exchanger. Each Heat Recovery Unit has a summer bypass fitted. 5. The manifold is used as a distribution system receiving air through rigid duct from the Heat Recovery unit and distributing the air into each room using several smaller 75mm semi-rigid ducts. 6. This duct to room outlet adaptor moves the air from the Ă¸75mm duct through 90Â° to a standard air valve connector. This reduces air speed on room entry, eliminating draughts and noise. 7. Semi-Rigid duct is used between the valve and manifold. Supplied in neatly coiled 50m lengths it is easy to handle, store and transport. Its smooth inner lining and strengthened corrugated outer layer make it flexible but hard wearing. It can be easily manipulated to changes in direction reducing the need for connectors and T-pieces and saving time on installation. .

Ventilation & Heat Recovery

Outside air is drawn into the house through a roof cowl or air brick (1 & 3). The Heat Recovery Unit (4) then transfers the energy from the outgoing warm stale air into the incoming cold fresh air. Meanwhile, the heat recovery unit supplies fresh air through ducting into living rooms and bedrooms through a valve in the ceiling.

Ventilation & Heat Recovery

The heat recovery unit Mechanical Ventilation and Heat Recovery (MVHR) systems consist of a central Heat Recovery Unit (HRU) located in the loft or in a cupboard with connected duct running to all the rooms in a house. The HRU has two fans, one to extract the damp, warm air from bathrooms and kitchens and one to bring in fresh air from outside. The HRU passes the outgoing air through the heat exchanger whilst simultaneously drawing fresh air from outside in the opposite direction. The two air streams are isolated from each other as they pass through the heat exchanger with the warm stale air transferring energy to the cooler incoming fresh air which is then supplied to bedrooms and living areas.

MVHR and CIBSE heat load calculations A 15% reduction for intermittent heating at the peak load can be made when using an MVHR system. This is because the MVHR system will be recycling heat energy, preheating the fresh air that is supplied into the building reducing the peak load.

CA350

When designing the system Timóleon use a static pressure of 150pa at 66%, this guarantees that the resistance within the ductwork can be overcome without having to increase the air speed, and potential for increased noise. It is crucial when comparing HRU’s that the unit has sufficient capacity, and is operating at a low static pressure so that the minimal sound from the fan or valves can be heard. This is very important when it comes to bedrooms and living spaces where HRU’s operating with a higher static pressure or fan speed will potentially cause excessive noise or ‘whistling’. Timóleon offer four passive house certified units can be supplied with a preheat to prevent the heat exchanger from freezing. The summer bypass comes as standard, and takes 100% of the extract air past the heat exchanger without heating the fresh incoming air.

Ventilation & Heat Recovery

Timóleon have a range of HRUs that suit different requirements and building sizes. Each HRU has a maximum flow rate. Timoleon design their systems within 66% of HRU’s capacity, this means that there is sufficient boost available when required.

Advantages at a glance

Our ventilation systems use the latest semi-rigid duct technology removing the need for many of the fittings required in a rigid duct system. As this is smaller and more flexible it is an easier and faster installation that suits both new-build and refurbishment. By having less fittings and easy push fit joints air leakage is reduced and the single duct run to each room results in significantly less cross talk noise. Installation is up to 50% faster than conventional rigid duct systems especially in suspended floors.

Ventilation & Heat Recovery

Why use Semi-Rigid Duct?

• No leaks • Easy to clean • Simple and quick install • Less fittings required • Connection from the manifold to the room in one length • No cross talk between rooms • No need for silencers • Straightforward balancing • Easy to cut and join • Flexibility means less accuracy required in measuring

Extract and supply valves Timóleon offer a range of valves which are specifically used for extract and supply. We can also provide ‘coanda effect’ valves that direct the supply air along the ceiling providing added comfort, reducing duct length and the improving the efficiency of the HRU. Valves are also available with fire proof dampers if building control require this specification. Alternatively Timóleon can provide fire collars that sit within the ceiling void above the valve. Fire rated collars are also available where it is necessary to provide this level of protection between floors or between adjoining properties.

Grilles, air bricks and roof cowls A range of grilles for low level walls are available when ceiling valves can’t be used. External Air bricks are also supplied for air intake and exhaust air from the HRU. If the fresh air intake and exhaust air cannot be supplied through an air brick, then a roof cowl can be installed for tile and slate roofs. All grilles, air bricks and roof cowls come in a range of colours.

Manifolds Timóleon supply plastic manifolds in 5, 10 and 15 port configurations. These manifolds are specifically designed to be used with the 75mm semi rigid ducting, unused ports can be plugged. These manifolds are low profile and can be housed within the plant room or loft.

Insulated ductwork A wide range of insulated products for ‘cold areas’ can be supplied where it is necessary to insulate the ductwork. This is to stop condensation forming. All the insulation products we supply meet NHBC standards, which states a minimum of 25mm insulation with a thermal conductivity of 0.04 W/mK.

Ventilation & Heat Recovery

60 years ago, the concept of circulating high temperature water from a boiler through radiators fitted in each room was still new. Since then, it has become the standard way of heating most buildings in the UK. The consequence is that more than 99% of the buildings in the UK are now dependent for their heating on a central boiler which uses a fossil-fuel. Yet we all know that these fuels are becoming increasingly more expensive. Government figures record that 4 million UK households were already in “fuel poverty” in 2009. Despite this, we continue to fit new buildings with heating systems that are dependent on high temperature fossilfuel boilers.

Solar Thermal

Timóleon SunCylinder. using solar thermal energy for the heating system.

What is the alternative? The recent big change has been the development of a new generation of high-performance underfloor heating products, for both retrofit and new build, which are able to provide very comfortable and effective heating while using water which is only 35-45˚C. Along with this, a new generation of solar thermal technology has been developed that can more effectively store and use the energy collected from solar thermal even on a winter’s day. These two developments - low temperature underfloor heating combined with a clever solar thermal storage and control system - mean that up to 40% of the building’s heat load can be satisfied by energy collected from the sun. Lower bills, faster payback and less reliance on fossil fuels. Timóleon underfloor heating systems are designed to use low water temperatures, low enough to use the heat collected by a solar thermal panel.

Soler Thermal

Solar Thermal Timóleon Solar Thermal Systems are able to collect the sun’s energy so that it can be used for both heating and hot water. All Timóleon hot water systems enable the homeowner to benefit from RHI payments as well as making significant savings on their energy costs.

Energy from the sun Solar thermal is very effective as an alternative energy source. In the UK we receive up to 1200kWh (units) of solar energy per square metre of land each year with energy available even on a cloudy day. Compare this to the annual heating and hot water consumption of a 3 bed house of about 10,000kWh and it is clear that solar can make a significant saving to the energy costs if collected and efficiently used. The energy collected from solar thermal can be very useful however during the spring, autumn and winter this is often at a low temperature. For this to be useful the underfloor heating needs to run at low water temperatures and have a control system that is able to make intuitive decisions based on how cold it is and the temperature of the stored water. This delays the need to use a boiler or heat pump until there is no useful energy available from the solar panels. Timóleon’s SunCylinder does just that, enabling up to 40% of the total house heating load to come from solar thermal energy. Timóleon also supplies conventional Solar Thermal systems for domestic hot water. These systems can supply up to 60% of the hot water demand (15% of the total house load).

The Renewable Heat Incentive (RHI) From Spring 2014 solar thermal installations providing DHW only can benefit from RHI payments. For applicable properties the proposed tariff will be 19.2p/kWh which for an average 3 bedroom property is ÂŁ600 per year. This is available for 7 years so the total payment would be over ÂŁ4,000. Add this to the saving on your fuel bills and using solar thermal makes clear economic sense.

For more information on the RHI please go to our website www.timoleon.co.uk or call us on 01392 36 36 05, weâ&#x20AC;&#x2122;ll be happy to help. Is Solar Thermal suitable for your projects? Solar thermal has an application in most projects. There has to be sufficient space on the roof and this must not be north facing. Panels should be installed at an angle between 300 and 450. Depending on the orientation of the panels and the application (space heating has a higher demand) more panels may be needed to collect enough solar energy. The number of panels needed for each application is explained in this guide.

Planning permission Planning permission is not needed for most solar thermal installations. There are exceptions, these being listed buildings, areas of outstanding natural beauty and conservation areas. It may still be possible to install solar collectors but planning permission will need to be sought.

Soler Thermal

Solar Thermal for Hot Water Timóleon has a range of packs for those projects that require a solar thermal system just for domestic hot water. Each pack is configured for the number of occupants within a building with the solar collector size based on standard orientation and location. If there any special requirements Timóleon can put together a bespoke package. Typically a combined collector size is about 3 to 5m2. Solar Thermal for domestic hot water (DHW) purposes is very well suited to high occupancy levels where there is a large demand for DHW and conversely less appropriate where there is a low demand such as commercial projects. The Timóleon solar collectors absorb the incident solar energy and convert it to useful heat. Solar fluid is circulated around the panels absorbing the heat. The fluid is then circulated through a coil heat exchanger situated in the hot water cylinder. Here the heat energy is transferred to the water in the cylinder. This water is used directly for the home’s hot water needs.

During the summer months the energy collected should be sufficient to provide nearly all the DHW energy needs. During the winter the water temperature from the panels is much lower and will need to be boosted by the boiler, heat pump or an immersion heater. All of our hot water cylinders have a second coil to enable a boiler to provide sufficient energy to heat the cylinder.

Solar Thermal

Temperature sensors are installed in the solar panels and the hot water cylinder to ensure the system only runs when there is heat to transfer from the solar collectors to the hot water cylinder.

Soler Thermal

Timóleon Solar Thermal twin coil systems Timóleon offer two cylinder variations to suit either a boiler input or heat pump input. As a heat pump will run at lower temperatures the heating coil size is larger. In each cylinder there is a second coil for solar thermal. There are 5 cylinder sizes from 180 litres to 400 litres to suit the occupancy level of the property. The Timóleon range of cylinders uses high specification Duplex stainless steel to resist all forms of corrosion whilst providing high mechanical strength. All cylinders are supplied unvented and with indirect heating supply via the primary coil.

Solar Thermal for Space Heating and Hot Water The SunCylinder from Timóleon is a unique patented product which enables solar energy to be used more extensively throughout the year. SunCylinder has an additional third coil and is usually larger as space heating requires more energy. A control system is also required to ensure the boiler or heat pump doesn’t automatically run when there is a call for heat, instead it decides whether the stored water is warm enough for the heating system given how cold it is outside. This then delays firing the boiler or heat pump until the solar thermal panels can no longer provide any useful energy. A conventional thermal store will automatically switch on the boiler whenever there is a call for heat and once fully heated the thermal store can no longer accept any solar energy. The most important component to ensure solar energy can be used most effectively is to have low temperature emitters. The Hydronik range of underfloor heating products from Timóleon are designed to run at the lowest possible water temperature utilising as much solar energy as possible. Using SunCylinder means more energy can be used by the property, this means the total collector area has to be larger to make best use of system, typically 7 to 10m2. Although the overall cost of the system is greater the payback is much faster.

The SunCylinder system What is the Sun Cylinder system? A unique patented cylinder design is used in conjunction with a control system. The cylinder has two input coils, one coil for solar thermal and a second coil for the auxiliary heat source, this coil is sized so either a boiler or heat pump can be used. The third output coil supplies the TimĂłleon underfloor heating system. The cylinder has the same footprint as a conventional cylinder with all the coil and sensor connections located conveniently on one side. The control system uses a pre-assembled â&#x20AC;&#x153;jigâ&#x20AC;? for simple on-site installation, this includes the necessary valves and circulator. The electronics are contained within the control box and provides an easy way to set up and commission the system as well as providing connection for the sensors and valves.

Controls

Aura is an innovative, stylish and holistic control system.

Introducing the Aura system from Tim贸leon. Bringing you innovation and style. Effective controls are essential in creating a comfortable living and working environment. This not only means controlling the temperature in a room but making sure the system runs only when it is needed. To do this the controls not only have to be accurate but easy to use. The Aura system is flexible, holistic and intuitive to use. It can accurately control the room temperature, program the hot water system and change the ventilation demand through one central touchscreen interface, the ControlPad. The Aura thermostat is a discreet, attractive fully programmable room thermostat. It can be used on its own or in conjunction with the ControlPad. The Aura sensor provides the same level of room control without the user interface. The sensors can be located discreetly within each room but collectively controlled by the central ControlPad. This makes controlling the system easier, rooms can be switched off as a whole as well as making the room controls tamper-proof.

Controls

1. Hot Water

4. ControlPad

The time settings for the hot water system can be set from the ControlPad removing the need for a separate timer.

Stylish all in one touchscreen allows complete control from one, simple interface.

2. Heating Whether using room thermostats or sensors the ControlPad gives the user a simple way to control all of the heating zones together. One-touch functions are displayed on the ControlPad that make controlling the whole heating system straightforward and intuitive.

3. Ventilation The whole house ventilation system uses the boost function to quickly bring in fresh air and remove any odours. The ventilation system also has a summer bypass facility that brings in cool fresh air during the summer.

108

The ControlPad brings together the multitude of controls present in a modern day home such as the room thermostats, domestic hot water timer and ventilation boost.

5. Sensors Discreet and unobtrusive, arean alternative to thermostats. With no thermostat in each room the programming for the heating system is done from the ControlPad.

Discreet sensors instead of obtrusive thermostats.

Home Screen The home screen has been designed for simple one-touch control of all the shortcuts and boost functions. There are no complicated programs to activate each function. All of the system settings are accessed through one button on the home screen and if youâ&#x20AC;&#x2122;re in doubt there is an information page on each screen.

Zone Lock

Settings

Heating Program

This function enables the user to lock or limit certain thermostats so that they can only be adjusted by a set amount. For example, in a school or nursing home the caretaker using this function can set certain thermostats so that they can only be adjusted by, say, 2Ë&#x161;C or locked altogether. This prevents tampering leading to unnecessary heating.

The settings for the one-touch buttons on the home page are set up here. The interface has been designed to be intuitive and simple to use yet without compromising on any of the features that a homeowner might need. Some of these features are shown on the following page.

The user can define the temperatures required throughout the day. This is displayed graphically to show when the rooms are scheduled to get warmer. The heating profiles are then applied to each zone. This simplifies programming as the user can simply change the profile rather than changing the settings for each zone on each separate day.

Introduction to Underfloor Heating The training addresses the total amount of energy used by UK buildings and how this must reduce. It introduces the European Energy Performance of Buildings Directive, EEPBD, which drives Building Regulations Part L. The training explains the science behind how UFH and radiators work, and how this relates to the new design principles. It describes the constituent elements of any UFH system, how these inter-relate and how these elements differ from the elements of a radiator system. The training goes into some detail, showing how UFH can be incorporated into any form of floor construction, including acoustic floors. Finally, the training considers how UFH works in conjunction with the whole range of different floor finishes, and concludes with its relevance to Renewable Energy.

Heating Buildings with Renewable Energy Where we are currently in the UK with regard to Renewable Energy, what are the pressures and consequences of the Government’s national CO2 target and what we have recently learned about how to reduce a building’s CO2 level. The training proposes steps we have to take in order to reduce the amount of energy a building uses in the future, and it’s CO2 The training considers Renewable Energy technologies collectively and then discusses them individually, explaining how they inter-relate. Finally, the training explains which key steps need to be taken first in order that other phases of RE can be more easily added to a building later in its life. 115

MCS Heatloss calculations We provide heatloss calculations for all project types and technologies, including heat pumps, biomass and conventional fossil fuel boilers where required. It is now a requirement for heatpump technologies to provide compliant heatloss calculations in accordance with MIS3005. This standard requires that specific criteria for the heat loss calculations are met and assesses whether the heat pump and heating emitters (UFH or radiators) meet the room by room calculations. As part of the Renewable Heat incentive (RHI) it will be necessary to confirm that the operating water temperature will meet the losses. This temperature determines the efficiency of the heat pump and the adjustment to the RHI payment.

If you need a more thorough room-by-room quotation and specification then please allow a bit longer.

Express Delivery

When we receive an order our standard procedure is to produce a detailed design and issue for approval before we then dispatch the materials. However if materials are needed in a hurry then Express Delivery offers a quick but simple way of getting standard products to site with a design for projects under a 100m2. Once we have received the order from the merchant we will aim to have the materials on site within 48 hours. We will produce the underfloor heating design as normal but rather than issue for approval we will dispatch the plans with the materials. As there is no time for design approval any on-site changes have to be met by the materials sent.

When sending in your plans please provide details of the floor construction, the floor finishes and the type of heat source. We would also like to know the insulation levels and glazing type. If it is a new build then simply state “built to current regs”. There are product specifications on all of our published datasheets. However, if you would like to discuss your project with us then please call the project team.

Placing an order Orders can be placed through your local merchant. They will need to know when the goods are required and the site address (unless it is being delivered to the branch) and a copy of your quote. The merchant will then call the Project Manager to organise delivery. From order we will provide a comprehensive underfloor heating design for your approval. Once agreed the materials will be dispatched and sent to site or the branch as required. Depending on design approval the process will take up to 10 working days.

Timóleon's pioneering free underfloor heating app updated with our latest range of underfloor heating products for all types of floor constructions. Underfloor heating (hydronic) systems are often considered the most comfortable way of heating a building. However, the performance of an underfloor heating system is often unknown as there are several factors that influence the heat output i.e the construction, the method of transferring heat from the pipe into the floor, the floor finish and the water temperature. Timóleon has developed this application to enable specifiers and installers to understand how well systems work with certain floor finishes and water temperatures. This can then be used to compare with the building heat losses. It is important to know that using a different floor finish won’t make the underfloor heating system ineffective. Equally, will the heat output from the underfloor heating be enough if a heat pump is installed working at low water temperatures? With the Timóleon app you will be able to tell what the floor surface temperature will be at certain heat outputs, making it a vital tool for specifiers and installers alike. The free Timóleon application is simple to use and produces accurate algorithms for your underfloor heating project. The data provided by this app is indicative and applies only to Timóleon systems and products. Please contact Timóleon for project specific data.
