The science behind the scenes We invest heavily in developing intelligent calculation software to ensure the complete accuracy and excellence of our system designs.
Optimiser A typical family house would have
360 items of data entered into Optimiser by the designer.
Sophisticated software for optimum underfloor heating performance Effective design of an underfloor heating system is fundamental to ensuring that the system performs to expectation. The design we create reflects how the property will be used, providing an energy-efficient solution.
Produces bespoke CAD design layouts Bespoke CAD design layouts are produced that detail the complete floor heating system ready for installation including:
Full heat loss calculations ensure precise performance Optimiser compares each underfloor heating system against the heat losses of each room to ensure precise performance is achieved.
• Entire system schematics
Meets British Standards BS EN 12831 and BS EN 1264 requirements Nu-Heat’s Optimiser is unique in that it calculates the heat losses of the property in line with BS EN 12831 and works to the underfloor heating design standard BS EN 1264. Taking every detail into account Optimiser factors in every other criteria into the design including floor coverings, which can impact on the heating response time, as well as ventilation losses and location of the property.

Intelligent interrogation of heat pump technology As the name suggests, our heat pump design software, Predictor, assesses performance and based on your project’s criteria, calculates the right heat pump technology for your project.
MCS & RHI Government funding Taking into account real-life usage, Predictor provides:
Weather-based performance simulation Predictor runs a simulation of performance over an average year, based on local monthly weather data from the Met Office and taking account of the changing seasons. Unlike other simulation programmes, Predictor uses the daily temperature cycle, including cold nights and warm days rather than the average daily temperature, for greater accuracy.
• A nnual Seasonal Coefficient of Performance (SCOP) figure and Star Rating for RHI annual payment figures
• A nnual energy usage and running cost predictions • A n energy summary for MCS compliance and certification
• A comparison with other fuel options such as gas and oil Optimum integration with underfloor heating When a heat pump is being integrated with underfloor heating, Predictor is run a second time, once the underfloor heating design is complete, to ensure that the heat source is matched perfectly to the heating system – just one of the benefits of choosing an integrated system from a single supplier.

PROJECT An extensive renovation, Plymouth LoPro™Max was the perfect heating solution for this renovation project in Plymouth, Devon. The superior heat outputs and low height build-up enabled the property to keep many of its original features, including sash windows, whilst still enjoying the luxurious feeling of underfloor heating.
How it works Nu-Heat’s underfloor heating provides a superior heating choice all combined with improved comfort, greater interior design flexibility and optimum energy efficiency.
N
W
UFH is up to
25% more efficient than conventional heating.
RADIATOR SYSTEM
UNDERFLOOR HEATING
Radiators circulate heat inefficiently meaning thermostats have to be typically set 1 or 2 degrees higher to achieve the same comfort levels as UFH. The room temperature is highest at the ceiling and coldest at the floor. Excessive air circulation increases ventilation losses, making fuel costs higher.
Creating ideal comfort conditions, underfloor heating, with its jointless multi-layered UFH tubes, provides even warmth, eliminating stuffiness, draughts and dust movement as well as giving you space-saving interior design freedom. And with significantly lower water temperatures, underfloor heating saves you both energy and money.
How it works A conventional radiator system works by passing high-temperature water through a sectional metal panel. The water flow temperature has to be high due to the small surface area of the radiator, which results in lower overall efficiency with modern condensing boilers and more importantly, heat pumps.
How it works UFH works by pumping a controlled flow of warm water, from any heat source, through tubing embedded in the floor. Because the emitting area is large, sufficient warmth is provided across the whole floor surface to heat the room effectively. With low water temperatures required, underfloor heating is the perfect partner for both condensing boilers and heat pumps, providing the highest levels of energy efficiency and lowest possible annual running costs.

Joisted floors are suspended timber floors that use joists to support the floor deck. The underfloor heating system lies either between or straddling the joists.
PROJECT SUITABILITY • N ew build • E xtensions • N o height build-up – sits within floor structure • R etrofit
Nu-Heat’s range is designed for use within a suspended timber joisted floor. To allow other trades to get on with work on upper floors, Nu-Heat’s patented ClippaPlateTM can be installed from below so that the floor deck can be fitted early on, prior to the underfloor heating tube being installed. Alternatively, by installing ClippaPlateTM over joists and then laying the floor deck, trades can work quickly without damaging the underfloor heating and with a reduction in the potential Health and Safety issues relating to open floors. How it works The flexibility of Nu-Heat’s FastfloTM tubing allows installation in suspended timber floors from either above, before the deck is laid or from below, after the deck has been laid, with no additional floor height build-up. The tubing is fed through pre-notched or drilled joists and held securely with Nu-Heat’s patented aluminium ClippaPlateTM, allowing the system to be fixed with little effort.
The ClippaPlateTM system uses highly conductive aluminium heat spreader plates to rapidly transfer heat from the FastfloTM pipe through the floor deck into the room above, efficiently and effectively. There is also a floating floor solution for joisted floor constructions.

Floor covering
As the UK’s leading supplier of retrofit UFH solutions, our award-winning LoProTM10 is suitable for a wide range of existing properties looking to upgrade their heating system. It can be installed over any existing floor and on any floor level and has just 15mm height build-up, the same as a 5p coin.
PROJECT SUITABILITY • R enovation & retrofit • E xtensions • M inimal height build-up • O ver any existing floor • S uitable for any floor covering
Quick and simple installation with just 15mm height build-up LoProTM10 is a floating floor with minimal height build-up and enhanced thermal properties, ideal for use with gas, oil and LPG condensing boilers. It is simply laid over any floor deck and across any floor level, making it suitable for retrofit projects as well as new build. Unique in the market, the edge detail is flexible so that LoProTM10 can fit irregular shaped rooms, often found in older properties. How it works Gypsum board is laid over an existing floor deck. The tube is inserted and a castellated panel is used to run the tube back to the manifold and for any irregular areas. LoProTM10 provides a practical, economical alternative to a traditional radiator-based system and is designed for use with existing or new boilers. A LoProTM10 system requires a flow temperature of 45-55oC – much lower than a typical radiator system, which would have a flow temperature
of 70-80oC – complementing the performance characteristics of condensing boilers perfectly.

LoProTMMax offers industry leading heat outputs and the fastest response times available, making it ideal for older properties with lower levels of insulation or those with large amounts of glazing. All this with a height build-up of just 22mm.
PROJECT SUITABILITY • R enovation & retrofit • E xtensions • N ew build • M inimal height build-up – average 22mm • O ver any existing floor • S uitable for any floor covering
Another option from the innovative LoProTM range, is LoProTMMax. It is a floor construction that uses a specialist self-levelling compound with only 22mm height build-up. Achieving outstanding heat output and response times, it also creates a perfectly level surface for tiling. Operating at one third of the running cost of an electric underfloor heating system, and with its impressive heat output levels, LoProTMMax is ideal for properties where there are lower levels of insulation and heat loss is an issue; situations where previously underfloor heating simply wouldn’t have been an option. How it works The system uses a vacuum-formed castellated panel to securely hold the floor heating tube in place before being covered by a specialist self-levelling compound, LoPro™QuickSet. The compound is highly conductive and provides a robust and perfectly level floor surface, which can be walked on in as little as eight hours and is ready for tiling after just 72 hours, depending on conditions.

Nu-Heat is exceptionally experienced with acoustic floor constructions. We work in partnership with Knauf to deliver high performance, high mass, gypsum based flooring products specifically designed to work with Nu-Heat’s range of UFH solutions. In partnership with Knauf, we independently test the acoustic performance of floors at professional test facilities such as SRL, which proves that airborne and impact noise levels meet or exceed Part E of the Building Regulations. Typical applications include office to residential conversions, flats, apartment blocks and multi-storey commercial premises. How it works UFH tube is integrated into a floor cassette comprising construction elements proven to improve acoustic performance – meaning airborne and impact sound levels are reduced. Components vary for different floor
constructions and are dependent on the specification, structure and heat output requirement. The use of an acoustic floor cassette can often reduce overall build costs.

A floating floor is a floor that doesn’t need to be nailed or glued to the subfloor and is supported on a continuous layer, usually of insulation.
PROJECT SUITABILITY • N ew build • E xtensions • L ess height build-up than screed • Over solid concrete slab • O ver beam & block • O ver suspended timber joists
Nu-Heat’s floating floor constructions comprise Extra High Density (EHD) panels and heat diffuser panels. It is important to fit the UFH over insulation with sufficient strength (kPa) to withstand the load of the intended floor and covering. How it works Nu-Heat’s pre-tracked TriPanel is laid over the insulation layer and metal heat diffuser plates are then positioned into the grooves. The heat from the tube is spread quickly and evenly by the diffuser plates, providing excellent heat output. A floating chipboard or Knauf Brio board deck may be used on top, or the panels can be installed between the joists in upper floors.

HOW IT WORKS 1. Extraction It takes an inexhaustible free supply of low-grade solar energy stored naturally in the ground.
S UT
ID
ID NS
E
E
3. Input vs. Output To access this free environmental supply an energy input is required. In a well-insulated property every single kilowatt hour of electricity used to power the heat pump can provide up to three kilowatt hours of free energy. This ratio is known as the Coefficient of Performance (CoP), as shown in the diagram the CoP would be four, meaning the efficiency of the heat pump is 400% – compare this to a boiler at 90% efficiency and the advantage is clear.
2. Process Heat is absorbed from a cold space (i.e. the ground), processed and released for heating and domestic hot water. Even at temperatures as low as -20oC, a GSHP can supply significantly more energy as heat than it uses to extract it from the ground. 56 For expert advice call us on 01404 540650 or email us at info@nu-heat.co.uk
4. Control Most systems are run using weather compensation control, allowing the heat pump to vary its operation based on the temperature requirements of the house in relation to the outside air temperature, time of day, etc. 5. Storage The heat pump also provides all your domestic hot water needs on demand and can be combined with Nu-Heat’s solar thermal panels for even higher energy savings and lower running costs.
Ground source heat pumps Nu-Heat’s range of ground source heat pumps (GSHPs) is designed to supply the home with inexpensive and environmentally friendly heating and hot water using heat stored in the ground.

Heat water using the sun Solar energy is a free, unlimited resource that produces no harmful emissions and requires no transportation or supply pipelines.
How does solar water heating technology work? Energy from the sun warms fluid in the solar panels. When the fluid reaches a useful temperature it is pumped to a coil in the bottom of a solar cylinder. The solar coil heats the cylinder water for domestic use. If the cylinder’s temperature sensor detects that the solar panel has not collected enough energy to heat the water to its pre-set temperature, the main heat source (i.e. a boiler) can top it up. The control panel can be set to optimise efficient use of the solar panel and ensure hot water is available at the times you need it. Ideal for... • Pitched roofs • Flat roofs • G arden structures, so long as the distance between the solar panel and cylinder is practical.
Achieve optimum efficiency with Nu-Heat Know-How system design Nu-Heat designs and supplies a complete, ready-to-install package comprising the solar hot water cylinder, solar panels (often called collectors), and ancillary components. Our specification is based on: • Hot water demand • Orientation and angle of the panels • A mount of overshading from trees and surrounding buildings. Using its own unique calculations package to specify the ideal combination of cylinder, solar panels and ancillary components, the Nu-Heat design and system sizing process has been developed in conjunction with European solar design software, TSol, as well as the government’s Standard Assessment Procedure (SAP) building regulations assessment criteria. Every Nu-Heat quote details the estimated annual proportion of hot water the solar collector will supply, based on the individual demand for the household.

FAQs We have put together answers to frequently asked questions concerning all aspects of our products and services. If you have any further questions, do give us a call.
UNDERFLOOR HEATING Is underfloor heating cheaper to run and more efficient than radiators? Yes, UFH is up to 25% cheaper to run than radiators with a condensing boiler, and up to 40% cheaper to run with a heat pump. Source: EuRay 2005. Is my property suitable for underfloor heating? All new UK properties will be suitable for UFH, as they meet strict guidelines on insulation and air tightness. Older properties can have UFH too, thanks to retrofit solutions that offer high heat outputs. Can you use underfloor heating on upper floors? Yes, with over 60 floor constructions, including specialist acoustic floor options to reduce noise, we have every situation covered. Is the make-up of my existing floor suitable for underfloor heating? We have over 60 different floor constructions to choose from, so there will always be a suitable match. Is underfloor heating suitable for renovations? Yes, our low profile LoPro™10 and new LoPro™Max systems have been designed for renovations and retrofit projects.
66
Can underfloor heating be mixed and installed through old and new parts of a property? Yes. Do I need a special boiler? No, underfloor heating works with gas, oil and LPG boilers as well as heat pumps. Can I link underfloor heating directly off a radiator circuit? A LoPro™Max OneZone™ system can be linked directly from a radiator system. Full system solutions can work alongside any existing radiator system. Will it work with my chosen floor covering? Underfloor heating works with most floor coverings. Your system designer will take the floor covering into account when specifying the amount of tube needed in the floor to heat the room effectively. Is underfloor heating disruptive to install? The LoPro™ range can be installed over any existing floor with minimal height build-up and on any floor level. With over 60 systems to choose from, options range from installation over solid floors to solutions that can be fixed from above or below joists. How long does the underfloor heating install take? This differs with each floor construction and we will advise on timescales at the quote stage.
For expert advice call us on 01404 540650 or email us at info@nu-heat.co.uk
What is the best way to use my underfloor heating system? This depends on the floor construction specified. Floating floors heat up more quickly than screed for example. Our new LoPro™Max floor construction can be used in exactly the same way as a radiator system, without a ‘setback’, because it heats up extremely quickly. A traditional screed underfloor heating system takes time to heat up from cold so is best used with a ‘setback’ temperature. Your Nu-Heat Technical Account Manager and User Guide will cover this. What happens if there is a fault or a leak? There are no joints in the underfloor heating tube laid in the floor and the tube we supply has a design life of over 50 years. So, unless the floor is badly damaged, it is extremely unlikely that there will ever be a leak. Do you offer product guarantees? Each product we supply has its own guarantee, our tube has a 50 year third-party insurance up to £1m per claim. Our tube supplier is quality assured to ISO9001 and our underfloor heating tube is designed to the highest European industry standards; DIN16892 – general requirement and testing for cross linked polyethylene tubes and DIN4726 – oxygen permeability in heating tubes. Please contact us for more details.
HEAT PUMPS Which is better an air source heat pump (ASHP) or ground source heat pump (GSHP)? Sufficient external space is the main criteria for the installation of a GSHP, which tends to rule out many urban properties. In terms of cost, the difference between a GSHP and an ASHP is comparative but the groundworks associated with a GSHP can be significant. Each project should be assessed individually.
Do I need anything else? Yes, other than the solar panels you will need a hot water cylinder and ancillary components. SERVICE What is the order process and timescales? You can expect your bespoke quotation within 72 hours. Once the order is made, we aim to design the system to suit the individual project timescales.
