Historic hotel, modern boilers Meeting the ventilation challenge

ATAG Commercial has supplied four floor standing XL-F boilers to the historic Littlecote House Hotel, Hungerford, replacing four longstanding units as part of a major plant room renovation. This was the first installation of the XL-F in cascade in the UK.

Founded in the mid-1500s, this Grade I listed Tudor manor has 208 bedrooms, a leisure club, restaurant and spa – all of which required a modern and reliable heating system.

In order to fulfil the hotel’s requirements, three XL210F boilers and one XL180F floorstanding boiler were specified and installed in early 2021. The whole process was undertaken and managed by Farehambased mechanical and electrical building service engineers, J&B Hopkins Ltd.

The new boilers benefit from dual heat exchanger technology, which provides built-in redundancy, while creating a cascade system within a single unit. The XL-F boiler is a ‘plug and play’ system, with the pumps, water non-return valves, and flue non-return valves neatly integrated inside, resulting in reduced set-up time and costs.

All models in the range benefit from an excellent footprint to power ratio which enables them to be fitted in small plant rooms. ◼ phamnews.co.uk/921/40 Ventilation solutions from Gilberts Blackpool have been used in the latest visitor attraction based on TV’s ‘I’m a Celebrity…Get Me Out of Here’. The 2500m2 facility in MediaCityUK, Manchester, includes climbing walls, zip wires and tree top trails.

Kimpton Energy Solutions designed and installed the mechanical building services for the back-of-house areas.

The ventilation equipment provided by Gilberts was designed to ensure adequate fresh air into the enclosed areas, and exhaust of used air, all while being unobtrusive in the customer facing areas. The solution was to utilise the company’s GSF omni-directional swirl diffuser with coanda plates to induct high volumes of air into the areas, without draughts or cold ‘dumping’. Gilberts’ GSXE exposed circular perforated diffusers provide extraction. ◼ phamnews.co.uk/921/39

Macerator pump keeps museum in ship-shape order

The Saniflo Sanicubic macerator pump has been specified for a replica of the famous ship, the Golden Hinde, known for circumnavigating the globe during the 16th century under the command of Sir Francis Drake. Sitting in dry dock, the replica ship is now a stunning floating museum and events venue near London Bridge.

A Sanicubic was first installed a couple of years ago in the dock beneath the ship to take the waste from two WC cubicles. It discharges waste up and along the dock walls through 35mm pipes to connect to the sewers above street level. When the team decided to install on-board facilities during the lockdown, Sanicubic fit the brief. Located beneath the floorboards in the bow of the ship, it is positioned to take waste from two new WC cubicles and basins as well as a new kitchen area in the galley. A dishwasher, sink and ice maker are all plumbed into the Sanicubic thanks to multiple outlets. ◼ phamnews.co.uk/921/41

Heat pump solution for new homes

The monobloc air to water Therma V heat pump by LG has been selected to provide heating and hot water for three new homes built by niche builder RS Construction in Sparkford, in the countryside just outside Castle Cary in Somerset. The three properties all benefit from high levels of insulation which make heat pumps the perfect solution for energy efficient, low cost heating and hot water.

Roger Walters of RS Construction says he only installs renewable heating systems now: “We only build three or four new homes a year but we build them to extremely high specification so that our purchasers get real value for money. The LG Therma V monoblocs are perfect for the quality of home we build and set something of a template for other housebuilders as we head towards 2025 and the government’s ban on the use of fossil fuel heating systems.” ◼ phamnews.co.uk/921/42

When it comes to connected heating controls, the market is ever-growing as new technology is introduced. One of the latest additions to the connected heating control space is that of Bluetooth, a technology that most installers will have heard of, but may not have come across in heating controls before. So, what do you need to know before recommending this technology to a customer?

What’s the diff erence between Bluetooth and Wi-Fi connectivity? Although both Bluetooth and Wi-Fi are wireless forms of communication, the two are very diff erent in terms of their capabilities. Whilst Wi-Fi allows devices to connect to the internet, Bluetooth operates via a short-range data transfer between two devices.

How far will a Bluetooth connection reach and can it be used remotely? A Bluetooth connection is only short-range, meaning that any app-operated heating control featuring this type of technology will only be connected to the system when the user is at home, as this will be within range of the thermostat. Depending on the size of the house and footprint of their property, some customers may fi nd that the Bluetooth range also extends into the garden or driveway.

Who is a Bluetooth heating control suitable for? The fl exible nature of Bluetooth connected products means that installers are able to off er a solution that meets the needs

Knowing about the benefi ts of Bluetooth

Bluetooth may have been around for quite some time, but it is one of the technologies that is more recently being incorporated into heating controls for a simplifi ed customer experience. Here Dave Kempster from Drayton answers some of the commonly asked questions about Bluetooth technology and how it can benefi t both installers and homeowners.

of any customer – whether they be a tech-savvy family looking to upgrade their system or an older customer who is simply after a control that they can simply set and forget about.

A heating control with Bluetooth connection is a great option for customers who may be looking for the convenience of altering their heating schedule on an app, like a smart control, but don’t necessarily need or want the ability to adjust their heating schedule when they’re out of the house. For many homeowners, this level of control would likely be more than enough while still off ering the level of convenience they’re after when it comes to managing the schedule easily.

This type of product is also ideally suited for local authority and social housing jobs, as well as private landlords. Over recent years, the interest in smart and connected technology has signifi cantly increased amongst tenants, with some taking it upon themselves to replace the system in place with a smart alternative.

A hybrid heating control, like our new Digistat, helps satisfy this demand, allowing tenants to benefi t from the ease-of-use

of an app-controlled heating system, without needing to have Wi-Fi in place. Not only is this great for properties where change of occupancy may be quite frequent, but it also means that once a tenant has vacated the property, the short-range nature of a Bluetooth connection means they will no longer be able to access or control the heating system via the app on their phone at a later date.

New Digistat

The new Digistat is the fi rst hybrid heating control from Drayton that combines the familiarity and simplicity of its popular Digistat range with the connected technology found in smart heating controls. The Bluetooth connectivity allows a user to manage the system via the Wiser Home app where they can utilise the smart modes, such as Away Mode and Delayed Start, which off er 24% and 10% energy savings respectively.

Meanwhile, for extra convenience, Boost mode allows users to temporarily increase the desired temperature for a short period without having to adjust the schedule, whilst Timed Away Mode is ideal for pausing the schedule for longer periods of time, allowing users to set a start and end time and date, similar to a Holiday Mode function.

With the new Digistat, installation and handover is also easier than ever. Installers simply select one of the pre-set schedules for their customers, after which the homeowner can either tailor the settings via the thermostat or they can be directed to download the app where they can create a schedule suited to their daily routine. With the right system, such as the new Digistat, the app will be easy enough for users to navigate so that installers should experience fewer call-backs from customers unsure of how to adjust their settings.

As well as off ering installer familiarity and ease of installation, with the receiver of the RF models being compatible with the standard UK wallplate, the four variants of the new Digistat all off er key features such as the service interval and lockable installer settings, simplifying the selection process and streamlining the levels of stock kept in the van. ◼ phamnews.co.uk/921/45

TRVs – good things come in small packages

They may be relatively small cogs in a central heating system, but thermostatic radiator valves are essential to achieving system effi ciency and user comfort. Here, Gareth Ash from Danfoss considers the sometimes underrated role of the TRV in reducing domestic heating costs and carbon emissions.

Invented by Danfoss back in 1943, radiator thermostats (TRV) remain essential to achieving the optimum effi ciency of most ‘wet’ domestic central heating systems. This claim is supported by heating control tests carried out in the Energy House at Salford University. The results highlighted the importance of TRVs to ensure satisfactory heat distribution around a dwelling. If set up correctly they can help consumers cut their energy use by maintaining the required temperature for each room rather than just heating the whole house, including unoccupied rooms, to the same temperature.

While every professional installer will be familiar with fi tting TRVs, we believe the true energy-saving value of this essentially simple device is not always fully appreciated. In addition to the potential savings in fuel consumption already mentioned, when they are used as part of a hydronically balanced system, TRVs will also prevent unwanted overfl ows and wasted energy through the radiators. According to some fi gures, this could bring up to 36% of extra savings for homeowners compared with constantly open manual valves.

Informed choice

Although ostensibly working to the same principle, the TRV has evolved signifi cantly since the concept was fi rst introduced. There are now many more options on the market, including electronic solutions that use wireless technology to provide end users with eff ortless (and more energy effi cient) heating control via a smartphone app. This vast array of products can be daunting for even the most experienced installer. However, making an informed choice, rather than simply sticking with what you know or picking the cheapest option, can be key to keeping customers happy and securing new and repeat business.

Gareth Ash

Danfoss marketing manager

When they are used as part of a hydronically balanced system, TRVs will also prevent unwanted overflows and wasted energy through the radiators

Understanding some of the main diff erences between the various products on the market, such as the type of sensor, can help avoid potentially costly call-backs if the TRVs don’t perform as promised. As every heating professional knows, TRVs work by sensing the air temperature around them and regulating the fl ow of water through the radiator they are fi tted to. Inside each TRV head is a sensor containing a material which expands as the room temperature warms up and contracts when it cools down. The sensor is connected to a valve seat inside the body that opens as the sensor contracts and closes as the sensor expands to allow more or less water through.

While this concept is in itself very eff ective, the material used inside the sensor will aff ect the TRV’s overall performance and accuracy. This is because diff erent materials have diff erent thermal properties, initially and over time. Needless to say, a TRV with a sensor that off ers a faster response to a change in ambient temperature means improved comfort and energy savings.

On average, response times range from just 1 minute for an

Electronic TRV, 10 minutes for a gas sensor, up to 22 minutes for liquid, and as much as 40 minutes for a wax sensor. We believe this diff erence is something installers should be aware of when selecting TRVs for their customers.

Smart heating

Given the increase in smart home devices, from sound systems to refrigerators, it’s not surprising that heating controls have also got smarter, like the Danfoss Eco radiator thermostat, for example, which allows the programming of individual radiator thermostats via Bluetooth using the Danfoss Eco app. The intuitive app makes it simple for households to program the heating to suit their daily schedule and keep rooms comfortably warm when occupied, and cooler when empty.

An electronic plug-and-play solution, Eco demonstrates how TRVs have evolved to become part of the ‘Internet of Things’. Quick and easy to install, these next generation controls enable consumers to experience some of the key benefi ts of intelligent heating for a relatively low investment cost.

Balancing act

Although the process of hydronic balancing is sometimes neglected during the installation and commissioning of a domestic heating system, it is essential to ensuring that the system operates at optimum effi ciency for maximum consumer comfort at minimal operating cost. In a properly balanced system, water fl ows equally to individual radiators and prevents cold or hot spots emerging, or the property not heating at all. As well as the discomfort factor this can cause, the effi ciency of an unbalanced system is signifi cantly reduced, increasing energy consumption and fuel bills for consumers.

In another example of recent innovations in TRV technology, Danfoss has now created a high effi ciency TRV with a built-in diff erential pressure controller for fast and simple hydronic balancing. By demonstrating a constant fl ow in all conditions, the Danfoss RAS-B2 ensures each radiator receives an equal fl ow of hot water. This not only optimises comfort but also means that the return temperature is lower (condensing boiler effi ciency is best at below a return temperature of 55°C) and the pump can run at a lower speed. Furthermore, presetting of the desired fl ow is done on the valve, rather than on the lockshield, which it is estimated could save installers up to two hours of valuable working time.

Regulatory recognition

In light of the proven benefi ts, the latest version of the European Performance of Buildings Directive (EPBD) has made individual room controls, such as self-acting TRVs, a mandatory requirement (where feasible) for any new heating installation. And if they are not present in existing homes with radiators they should be fi tted when the boiler is replaced.

The long-awaited update to Part L is expected to follow the EPBD’s lead, which would mean installing basic radiator valves will no longer be an option. At Danfoss, we believe regulatory recognition of the TRV is good news for the industry and end-users. Properly selected and installed, modern TRVs off er an easy-to-fi t solution for heating engineers and an aff ordable investment for their customers with an estimated payback period of just two heating seasons. So let’s give the humble, yet mighty, TRV the credit it so clearly deserves. ◼ phamnews.co.uk/921/46

Why it’s so important to be open minded about controls

There are lots of factors to consider when choosing a thermostat, including matching the complexity of use to the user, but OpenTherm technology should be a no-brainer. Tristan James from ESi Controls explains how OpenTherm will enhance the energy efficiency of any heating system.

From sophisticated users who want the latest WiFi controlled options, to elderly or vulnerable people who need the simplest of controls to cope with their heating system – it’s vital that there’s a full spectrum of complexity available in today’s heating controls marketplace. We here at ESi are able to offer a control suitable for any home.

The decision as to which control system to include in a new build heating installation or a replacement project is not always straightforward, with a wealth of options available and a range of component combinations. It’s vital that the controls meet the requirements and limitations of the users. There is no point installing the latest WiFi or Bluetooth connected controls if the user is unable to fathom out how to use it. If they need a straightforward dial control, then that is what you should install.

Clever use of controls can help minimise energy consumption by ensuring each room is at the right temperature for comfort, whilst avoiding overheating. This will help to keep your customer’s home cosy and cut their energy bills too.

Open system

As well as offering Boiler Plus compliant units, we – a member of the OpenTherm Association – offer access to the OpenTherm protocol. OpenTherm is a nonmanufacturer dependent system of communication between modulating HVAC appliances and room thermostats. It consists of a communication protocol and an interface specification that allows modulating heating appliances to communicate directly with the heating controls within the property.

More and more appliance manufacturers are bringing modulating central heating systems onto the market – traditional boilers and renewable options – including many heat pumps. These appliances offer better efficiency and reduced environmental effects. However, to operate these appliances, a communication protocol between the appliance and the controller is required. It involves the addition of software only available to OpenTherm Association members.

By having constant communications between the thermostat and the boiler, the heating controls can accurately control the appliance’s heating output, ensuring the correct amount of heat is given to the heating system at the correct time. In terms of OpenTherm gas condensing boilers, this leads to significant energy savings by keeping condensing boilers in condensing mode for much longer durations.

Simple solutions

OpenTherm allows third party control manufacturers to create a wide range of simple control solutions for boilers. Over-complicated controls can lead to energy wastage, but simplified OpenTherm controls can lead to greater flexibility. By having a range of control solutions beyond the manufacturer’s own controls, installers have freedom of choice and the knowledge that whatever OpenTherm control they choose, the boiler would always run at its most efficient point.

Some OpenTherm thermostats can inform homeowners when they have run out of gas or the heating system has a leak, thanks to communications between the boiler and the thermostat. OpenTherm allows remote boiler diagnosis too, which can lead to service intervals being extended, reduced downtime and ultimately saving money. Whilst the amount that can be saved on energy costs by using OpenTherm varies between installations, 10% is a reasonable estimate, and up to 15% is not uncommon.

The beauty of OpenTherm is that it can be applied not just to modulation condensing gas boilers, but to any heating and hot water system that uses the OpenTherm protocol. So, an OpenTherm gas boiler and OpenTherm control fitted right now could be easily added to an OpenTherm heat pump and OpenTherm MVHR system in the future. OpenTherm can easily be changed and adapted.

Group effort

ESi is just one of the companies signed up to the OpenTherm Association, working together with the aim of introducing a wider acceptance of OpenTherm as standard in the UK. Manufacturers of boilers and controls that have already evaluated the OpenTherm protocol’s compatibility with their systems include major companies in Europe with an influence in the UK –wanting to see the acceptance of the OpenTherm protocol, here in the UK marketplace. Recognising the common sense in developing a common use ‘Open’ system here in the UK, the protocol importantly also has the support of industry bodies HHIC and BEAMA, who are committed to supporting OpenTherm’s wider introduction here.

Understanding smart systems

Smart heating controls will play a key role in enabling the country to operate more sustainably, so it’s essential that installers fully understand their range of capabilities - says Richard Harvey from Wolseley Plumb & Parts

Everything is smart now, from phones to TVs, cookers to fridges and everything in between. Demand continues to rise for smart heating controls in particular, with several factors contributing to its popularity. Recent events mean people are spending more time at home, leading to an increased expenditure on domestic improvements. At the same time, hybrid work patterns are now in place, making it more imperative that heating systems can cope with an everchanging schedule.

Boilers providing domestic heating and hot water account for 80% of all energy consumption in the home. According to Beama, adding upgrades such as advanced room thermostats and thermostatic radiator controls can provide homeowners with a total reduction of 32% on their heating bills.

While demand continues to grow, there is still a hesitancy from installers to fi t smart systems into homes. Some harbour a fear that this technology is just another gimmick that will fade away without delivering the benefi ts. The basics Firstly, it’s important to remember that ‘SMART’ is actually an acronym to describe what devices are capable of – SMART stands for: Self-Monitoring Analysis & Reporting Technology. Traditional thermostats off er users basic functions including on/off , timers and essential temperature controls. A smart stat gives users complete management of their heating schedule through smartphones or tablets. They don’t even have to be in the home to set the temperature for rooms and start timers.

To enable homeowners to enjoy the benefi ts of smart heating, installers must learn new skills to fi t the most up to date systems. This requires installers training up to understand the benefi ts and installation techniques. Most smart controls providers off er this for free.

Multizone heating will be a staple of homes for the future. With the next update to the Building Regulations looking highly likely to feature energy

effi cient heating, installers must be profi cient in installing smart controls and not get left behind by the change. These controls will be a key enabler for meeting the new regulations. New Building Regulations will also accelerate the retrofi tting of heat pumps and hybrid heat pump systems to help that greener push. Richard Harvey With new technologies Commercial Director for Plumbing & comes new controls Heating at Wolseley Plumb & Parts and new knowledge to be shared with homeowners, so it’s important installers and their customers understand how to get the best out of each system. What you need to know Installers must get to grips with the basics by understanding the benefi ts of the latest smart heating systems to educate customers. From better effi ciency to providing less strain on heating systems (meaning less maintenance checks), it should all be highlighted. Thermostats from the likes of Resideo and Hive provide clear information regarding the current status of a system, including potential issues. The initial outlay for multiple sensors may seem steep for some, but the increased control on heating is a good talking point to advise customers. Most systems learn heating patterns and automate heating around the house, providing further effi ciency. Another huge benefi t is load compensation. This common feature in smart controls and thermostats helps maintain the user’s ideal temperature. Devices measure the gap between what the internal temperature is and what the user wants it to be before modulating the boiler, so it only uses just the fuel required to close the gap. Installers must also shake off the mentality of fi nding the cheapest option in smart heating. This is often counterproductive, as that system may not be the most suitable for the user. The future of smart heating is not too far away. A smart heating system will no longer be seen as a a gimmick, but as an essential part of our lives in the same way as smart speakers and doorbells. ◼ phamnews.co.uk/921/48

Advancements in CO alarm technology

With around 60 fatalities every year, protection against carbon monoxide poisoning clearly remains vital, but recent technological advancements in the data extraction capabilities of CO alarms are serving to better inform and protect users. Andy Speake from Aico explains more about making our homes safer.

Carbon monoxide is a deadly and poisonous gas that is emitted by fuel-burning appliances when incomplete combustion occurs. Statistics indicate that in an average year, the UK records approximately 4000 instances of carbon monoxide poisoning, with 200 cases resulting in hospitalisation, around 60 being fatal and approximately 10-15% of those with severe CO poisoning developing long-term complications. Being odourless, colourless and tasteless, CO poisoning is also known as the silent killer, making adequate protection through CO alarms vital.

CO alarm technology has benefi tted from signifi cant advancements in recent years, providing some invaluable capabilities – most notably data extraction. Data extraction can be done in two key ways – either in-situ from the alarm head itself or remotely, depending on the alarm. If CO levels were

 The Ei3028 is a dual sensor Heat and CO Alarm, able to detect the presence of toxic levels of carbon monoxide as well as dangerous levels of heat. The AudioLINK feature enables the user to download information from the alarm via Aico’s mobile app to trigger the alarm to sound, an occupant is able to gain insight into this event, gaining information and reassurance. For landlords, the report generation capabilities through data extraction technology can prove useful in their mandatory checks and record keeping –this feature provides a physical, traceable record of the alarm history and status.

With remote data extraction technology, events can be monitored, and trends identifi ed, thus enabling proactive and informed maintenance for effi ciency. For example, if a resident removed the alarm head following an activation (which can be common but harmful and potentially fatal, due to the traceless nature of CO) remote data extraction tools can provide notifi cations of the alarm sounding, as well as head removals, facilitating resident health and wellbeing.

Trigger points

BS EN 50291, the standard that governs compliant CO alarms, defi nes the trigger points for CO levels to cause the alarm to sound: • 300ppm can trigger the alarm within three minutes • Low concentrations can still trigger the alarm to sound if present over time • 30ppm can trigger the alarm but can take up to 120 minutes to do so.

In CO alarms that contain the in-situ data extraction technology, such as our AudioLINK alarm, lower levels and background levels of CO can be detected, identifi ed and monitored. This is of key importance as there is a large and growing body of evidence and research highlighting the harmful eff ects of long-term exposure to lower levels of CO.

Research has demonstrated wider ranging implications from chronic exposure to low level CO, with reported eff ects on physical health, sensorymotor changes, memory defi cits and psychological changes. It has also been shown to have signifi cant negative impacts on pregnant women because CO is more readily absorbed by the blood of an unborn child and released more slowly, meaning that the unborn child’s exposure to CO is more prolonged. This has been linked to such outcomes as birth defects and even death.

Eff ects of exposure

A study comparing the eff ects of ‘less severe’ CO poisoning to ‘more severe’ found that those with ‘less severe’ had higher incidences of depression and anxiety, and this continued for six months.

These results imply that CO levels within blood are not indicative of the outcomes of CO poisoning, particularly as CO leaves the bloodstream fairly quickly after exposure and may not be detected. This means that proving where and when an incident of poisoning has occurred can prove to be a diffi culty faced by victims of CO poisoning and landlords alike.

With a recorded log of even lower levels of CO, the severity and length of exposure can be determined, as well as in what area of a property, to better advise on the next course of action following CO events and incidences of poisoning.

Furthermore, research has suggested that considering the product that the CO was emitted from, the concentration and duration of exposure provides a more accurate measure of determining the severity of CO poisoning, which can be provided using this technology.

In-situ data extraction also aids with identifying the source of the CO leak, should it not be apparent, benefi tting both contractors and landlords alike.

Raising awareness

Installers should be familiar with the data extraction capabilities of the CO alarms they are installing for a multitude of reasons, one of them being to educate occupants.

Education is vital, especially when it comes to home life safety, and the majority of the general public may not be aware of what CO is or even that a CO alarm will emit a diff erent sound to a fi re alarm.

In newer alarms, such as the Aico 3000 Series, there are built-in sound mimicking capabilities, so that when fi re and CO alarms are interlinked, the fi re alarms will emit the same sound as the CO alarm if that has triggered the system. This is a key feature to be aware of, to enable audibility throughout a property, allowing occupants to take immediate action and reduce confusion. In systems without the sound mimicking capability, it is worth recommending a Fire/ CO control switch (check manufacturer’s instructions and guidance) to enable occupants to quickly identify whether the activation is due to CO. ◼ phamnews.co.uk/921/59
