Hatfield Place, a luxury country house wedding venue, chose Junckers solid wood flooring fitted with Leveldek underfloor heating system for its newly developed building. The new foyer, ceremony hall and wedding breakfast room overlook the original walled garden, with views of the beautiful parkland to the rear. The redeveloped building is bright and airy with large feature windows and high ceilings. In the foyer, a spacious room with seating for up to 300 guests, Junckers 22mm Oak Variation flooring provides a warm and lively backdrop, adding character with its subtle colour variations and natural grain patterns. In contrast, the ceremony hall and wedding breakfast room were fitted with Junckers’ Oak Harmony plank flooring, a wide board floorboard which gives a more uniform impression required for the formal spaces. Both floor types were pre-finished in Junckers’ popular Ultramatt lacquer, a strong and durable finish with no surface sheen. Delivered pre-finished, the floors are ready to walk on as soon as they have been installed and will withstand years of dancing and dining with the correct maintenance. The floors in all three rooms were installed over Leveldek, Junckers’ fully integrated underfloor heating and levelling system. Working in partnership with Jupiter Heating Systems, the Leveldek system was developed to simplify the specification process to offer a versatile levelling system, underfloor heating and solid hardwood floor from a single point of supply. Underfloor heating is the most efficient way of heating a large, open area. Specifying Leveldek offered Hatfield Place an all-in-one solution whereas traditionally, installation of the heating system, levelling system and the floor itself would have to be separately sourced. The system is efficient and cost effective to run, ideal for use in a large space. For energy efficiency and fast acting warm-up time, the heating pipes are installed directly beneath the floorboards and the panels are insulated and reinforced for outstanding heat output. The system can be used on an uneven substrate as varying heights can be achieved with the stacking cradles. For more than 30 years, Junckers’ wooden floors have been recognised as the only type of solid hardwood flooring on the market stable enough to be guaranteed for use over underfloor heating. Junckers offers a full guarantee for the system, which is recommended for residential and commercial buildings as well as sports and dance. The flooring contractor was PICA Floorings. 

The Audley Stanbridge Earls retirement village is an exclusive residential development of 155 luxury retirement apartments and cottages designed around a Grade II listed Tudor Manor house on a 32 acre site near Romsey, in Hampshire. Underfloor Heating had been specified as part of the design and the large floor areas now needed to be finished with floor screed that could be installed quickly and efficiently within the operating windows provided by the main contractor.TOPFLOW Screed A Thermio + offers a higher thermal conductivity than conventional sand-cement screeds, can be laid thinner and fully encapsulates heating pipes without leaving any voids. This makes it ideal for use with underfloor heating systems where it helps to improve the thermal performance and energy efficiency of buildings. All TOPFLOW Screed A products are made from gypsum and are completely cement free, with a binder made from 98% recycled material. This gives it a lower carbon footprint than a conventional cement-based screeds, saving up to 20.45kg CO2e per m2, making it a more sustainable choice.

The 36 storey Grade-II listed, white-concrete high-rise tower, has been completely overhauled. Previously containing offices, but has now been converted to accommodate 82 apartments, including a penthouse ranging in price from £3 million to £55 million.During the refurbishment architects clustered corridors and bathrooms in the centre of the tower, making room for living areas and bedrooms to run alongside the windows, to make the most of the London skyline view.With approximately 12,700m2 of medium density gypsum fibre panels engineered with tongue & groove edges for ease of installation to create a monolithic robust surface over underfloor heating trays and 6mm Isorubber working as an impact vibration reduction mat. The panels installed were chosen due to their excellent thermal conductivity, a requirement for the system to work in conjunction with the desired underfloor heating system.

The revolutionary, award-winning underfloor heating system Schlüter-BEKOTEC-THERM was the natural choice for one of the UK’s greenest self-build projects.

A Grant Aerona³ air source heat pump has been installed at a home in Wiltshire, replacing the biomass boiler that was previously heating the property. Working together with an underfloor heating system, the Aerona³ heat pump is operating efficiently to deliver warmth and comfort throughout the home.

A new flooring solution was required as part of a large, high-specification selfbuild housing project on the stunning Archerfield estate in North Berwick. Underfloor heating had been specified for the ground floor of the house and it was important that the chosen floor solution would help to optimise heating efficiency. Given the scale of the project it was also important that the chosen screed solution could be installed quickly over a large area to fit within the build programme. Following initial discussions and a successful pump trial the customer decided to use Tarmac’s TOPFLOW Screed C cement based liquid screed.TOPFLOW Screed C is a free-flowing, cement based liquid screed that can be trafficked after just 24-48 hours and dries within 21-28 days. It can be pumped into place and allows large areas to be covered quickly with up to 120m2 laid in as little as 45 minutes. Fast drying times mean it can be laid later in the programme when the building is fully water-tight and still hit deadlines for installation of flooring. It is ideal for use with underfloor heating systems. As a self-compacting screed, it fully encapsulates heating pipes without leaving any voids and is also a more conductive medium than traditional sand and cement screeds, improving the thermal performance of the system. It is also compatible with most cement based adhesives meaning it can be used with a wide range of flooring types.The fast-drying times and early trafficking characteristics of TOPFLOW Screed C enabled other trades to follow on quickly, helping to provide continuity and efficiency within the client’s build programme. The contractor was delighted with the outcome, commenting on how good the material was to work with and on the excellent finish achieved.

The JACKOBOARD range from BEWI is “ideal” for use as a tile backerboard on projects where increasingly popular underfloor heating systems are being installed, the company says.Made from extruded polystyrene foam (XPS), the construction boards are said to be inherently waterproof because the structure of the board does not allow water to penetrate. They are designed to be easy to work with and cut, as well as truly lightweight.They are finished on both sides with a special coating and reinforced fibreglass mesh, ready to be tiled, rendered or plastered. The boards are said to possess excellent thermal insulation properties, which give them enormous advantages over plasterboard or cement board. They are especially suitable for interior construction, the company says, especially in rooms subject to high moisture levels.According to BEWI, JACKOBOARD goes “beyond bathrooms” and can be used in any room of the house and as a backerboard for virtually any tiling project.The boards are suitable for quickly and effectively levelling uneven walls and floors, for partition walls, compensating for cracks in substrates and for creating substrates for laying tiles on non-adhesive surfaces.JACKOBOARD is also said to provide the best waterproof, insulated, tiling substrate for underfloor heating projects. Whether electric mats or hot water systems are being installed, BEWI says, JACKOBOARD – laid underneath the heating elements or pipework – will help to decrease warm-up times of the system by pushing the heat directly up to the tile layer. In this way, the heat generated by the system is used in the most efficient way, not just during the initial heat-up stage, but in general usage with the continued thermostat-controlled use of the heating system.As builders are forced to reduce the carbon footprint of their projects, the materials they choose to build with can provide a key to unlocking the thermal performance of a building. The XPS foam used on JACKOBOARD products reportedly achieves excellent insulation properties. It’s designed to help maximise the energy efficiency of walls and floors, improving the overall thermal performance of any property.www.bewi.com

Guests to a new luxury spa at one of London’s most famous hotels are relaxing in comfort after the installation of the environmentally friendly underfloor heating system, Schlüter®-BEKOTEC-THERM, by Schlüter-Systems.

An Essex-based project centring on the provision of a much-needed National Autistic Society (NAS) school has seen the installation of electric underfloor heating system Schlüter-DITRA-HEAT-E-DUO into the 60 houses built to off-set its costs.

Tom Smith Plumbing and Heating Services, G1 Installers who specialise in renewable, eco-friendly technologies, completed the installation of a hattrick of Grant products in a new build property in Perranporth, Cornwall. An Aerona³ heat pump, Wave cylinder and Uflex underfloor heating system are working together to fulfil the heating requirements of this new family home.

Salthaven Apartments, Tower Road, Poole, DorsetThe Salthaven apartments in Dorset aimed to deliver luxury living for occupants. Bayview Developments not only constructed beautiful homes for them, but also opted for highly energy efficient heating within the new development.Each of the 12 two or three bed apartments have been fitted with their own individual exhaust air heat pump (EAHP). This technology has been installed in buildings across continental Europe for many years but is now being used more commonly within the UK. Bayview Developments were looking to exceed their planning requirements by reducing carbon emissions and providing cost savings for occupants. NIBE’s innovative EAHPs were therefore the ideal solution.The solution to the projectA NIBE F730 EAHP system removed the need for gas boilers, something Bayview were keen to do given the UK’s net zero targets and commitment to phase out the technology. As heat pump technology is powered by electricity, no gas has been installed at the site.The NIBE F730 unit can be found in the utility room cupboard of each apartment and is comprised of a ventilation system, a hot water cylinder and a heat pump – a complete ‘all-in-one’ product. It works by drawing warm air from the kitchen and bathroom to feed the heat pump, which extracts the heat energy. The recovered energy from the ventilation system is used to drive the heat pump process, which heats the underfloor heating and provides water for the integrated 180litre hot water cylinder. The stale air from the ventilation system is then released outside, whilst fresh air from outdoors is introduced via wall inlets with cleanable filters. The efficient system minimises energy consumption by combing ventilation heat recovery with heat pump technology, that is perfect for well insulated new build properties such as these.The ResultsThe EAHP systems meet the average annual heat demand of 6019 kWh for each individual flat whilst also providing instant hot water. Occupants are able to schedule their heating to suit their timetable and energy tariffs, and therefore benefit from lower energy bills. The system performance factor (SPF) measures 3.33 – this means the system is very efficient as every kW of electricity used to run the unit produces approximately 3 kW of heat energy.NIBE utilised connected electricity meters in 3 apartments to remotely monitor the systems performance across a 12-month period. NIBE was thus able to see how the systems met energy demand consistently for residents, keeping them comfortable and warm throughout the year.Energy consumption data shown in Figure 1 visualises electricity consumption data from the monitored apartments throughout the year. This data also covers the provision of all heat pump controls and continuous mechanical ventilation.Figure 1: 2022 Energy Consumption data for monitored apartments.The all-in-one system has shown a noticeable reduction in energy bills for each apartment too, with all 3 monitored apartments experiencing both monthly and cumulative cost reductions in their energy bills as shown in Figures 2 and 3. This comes with the additional peace of mind that consumers will be kept cool in the summer months with ventilation with no increase in costs.Figure 2 and 3: Monthly and Cumulative Heating Bills for Apartment 11 with the NIBE F730 heat pump compared to a natural gas boiler.The occupants of Apartment 11 are saving on average £130 on their annual heating bills with the heat pump system in comparison to a natural gas boiler, even with the additional provision of mechanical ventilation. We expect that these savings will continue to increase as the Government seeks to rebalance green levies to decrease electricity prices.Sunstone Energy Ltd, the installer for this project, told us how easy the control system is to use for this heat pump, allowing for heating and hot water to be available at any time during the day. The building also benefits from insulation, underfloor heating, smart controls, double glazing, hot water cylinders and mechanical ventilation with heat recovery (MVHR).TestimonialVictoria and John are both residents of the Tower Road apartment complex and have been comfortably living with the exhaust air source heat pump system for a year. They added “We are delighted so far with the new heating system, and love that it has been providing us with heating and hot water throughout the year, keeping us warm in the cold winter months. The heat pump works just as well as our older systems and it is great to know that we’re also doing our bit for the environment in the process.”About the installerSunstone Energy Ltd takes responsibility for delivering complete renewable solutions appropriate to their client’s properties. Their expertise includes the installation of ground source and air source heat pumps, underfloor heating, solar panels, biomass boilers and MVHR.  

Royal Winchester HouseComer Homes is renowned for the high quality of its residential and commercial developments, which span London, Hertfordshire, Dorset and throughout the South East. Its latest project is Royal Winchester House, a landmark building of one and two bedroom apartments at the heart of Bracknell's new town centre. As a planning requirement of Bracknell Forest Council, Comer Homes was required to provide a sustainable, low energy form of heating that would offer a reduced carbon footprint, as well as being affordable to run.The SolutionComer Homes specified F730 Exhaust Air Heat Pump systems from NIBE for all 337 apartments on the development to ensure they could meet their renewable targets. The new homes builder employed MKP Consultants Limited to undertake the building services design as they had previous experience of NIBE systems on other apartment developments in the area.The NIBE F730 Exhaust Air Heat Pump system was an ideal solution, as it offers mechanical extract ventilation, alongside heating and hot water in a compact design. The heat pump units were installed in a service cupboard in each apartment, as they have a small footprint of only 0.6m2.NIBE F730 operates by recovering energy from the ventilation air and, if desired, extracted from outdoor air, the heat energy is absorbed by the heat pump using a vapour compression process and subsequently transferred to the water-borne heating system, in this case an underfloor heating system. The integrated 180L domestic hot water cylinder also ensures a plentiful supply for the one- and two-bedroom properties.A sustainable solution, NIBE F730 keeps energy consumption to a minimum. The efficient control system automatically adjusts the indoor climate for maximum comfort for the occupant, using a combination of weather compensated control and the low energy inverter driven compressor.Each apartment is also fitted with a NIBE RMU 40 room controller, to allow greater flexibility of control for users and if required can be easily connected to NIBE’s internet remotely monitoring and control platform UPLINK™.Thanks to this innovative heat pump system, residents at Royal Winchester House are set to benefit from lower energy bills and a reduced carbon footprint.The ResultsThe NIBE F730 system complies with Parts L, F and G of the building regulations, and helps to meet planning requirements designed to reduce energy consumption and carbon footprints within residential housing developments. External noise is kept to a minimum and building aesthetics are unaffected by the need for external plant.TestimonialHead of Projects at Comer Homes, Jack O’Brien explains: “We were looking for a heating and ventilation system that would be both sustainable and affordable to run. We have been impressed with the performance of NIBE’s heat pumps, with their high efficiency, low noise and low running costs further enhancing the sustainability of the whole development.”About Royal Winchester HouseRoyal Winchester House is a landmark building of high specification 1 and 2 bedroom apartments available to rent.

South Lanarkshire College (SLC) in Scotland has opened a new, ‘zero-energy’ teaching block on its East Kilbride campus. Specifically designed with first-rate environmental credentials in mind, it boasts a whole host of efficiency-enhancing measures – including highly insulated floors, walls and roofs, triple-glazed windows, low-energy lighting and electrics, rainwater harvesting and solar PV panels on the roof. The college approached NIBE Pro Installer Anderson Floor Warming and Renewables in search of a system that would meet the heating requirements of the eight-classroom block in the most sustainable, cost-effective and reliable way possible.The SolutionSLC already has a range of NIBE products in its on-site renewables training centre, which students use for practical sessions, so a heat pump from NIBE was the natural choice to heat the new block. Mike Anderson, director at Anderson Floor Warming and Renewables, specified, designed and fitted a NIBE F1345 40kW ground source heat pump (GSHP) system to complement the building’s water-based underfloor heating, which operates at similarly low flow temperatures.ResultsNow up and running, the NIBE system is so efficient that it has been awarded a rating of A+++ in line with energy labelling criteria under the ErP Directive. SLC’s new teaching block has become the first building in the UK to achieve a BREEAM sustainability rating of ‘Outstanding’, with the facility excelling in all 10 assessment categories – from energy, waste and water to health and wellbeing.Customer Testimonials“We pride ourselves on our forward-thinking approach to sustainability at SLC, and we couldn’t be happier that our new teaching block has been deemed ‘Outstanding’ by BREEAM assessors. The NIBE heat pump system and the solar PV panels combined generate enough renewable energy to meet the block’s entire heating and power needs, making it a ‘zero-energy’ building. It really is a huge asset to the whole college – not only from a resource point of view, but also as a real-life example of sustainability in action. As well as being a valuable learning space for our construction and energy students, it’s a place for us to bring local businesses and community groups, and showcase the benefits of low-carbon, low-resource buildings first-hand.”Stewart McKillop, principal at South Lanarkshire College

The ChallengeFounded in 1432, Sevenoaks boarding school is one of the oldest and most prestigious in the country with some of the buildings dating from the 17th Century. The client requested an easy-to-use, energy-efficient underfloor heating solution in rooms of different uses across the school that would have a negligible impact on floor heights. The installation of the system would also have to be considerate of the historic nature of the building.The SolutionDue to the need for a low floor build-up and with a project featuring a mix of floor finishes, our Foil Heater was the ideal choice for an easy-to-use and quick to install underfloor heating system. The Foil Heater is perfect for use with the school’s carpeted and wooden floor finishes and was installed in conjunction the Dual Overlay System when fitted with the carpeted flooring for a stable subfloor solution that can handle heavier load areas.

Originally opened in 1863 and voted 'Best UK National Treasure' at National Geographic Traveller Magazine Reader Awards, the Grade 1 listed, iconic British landmark, The Temperate House at Kew, reopened in 2018 after a major five-year, £41 million restoration. Comprising five pavilions and showcasing over 10,000 new plants from all over the globe, this glass cathedral is the world’s largest Victorian glasshouse, protecting the often rare and tender plants throughout the UK’s cold winters. Commissioned in 2017 by renowned architects Donald Insall Associates - heritage and historic building specialists - and working with ISG, the global construction and engineering company, Britannia designed and manufactured 146 bespoke cast iron floor grilles - a total of 73 linear meters - to house part of the vast new sunken trench heating system. The original inadequate and inefficient heating, ventilation, and irrigation systems were no longer in adequate condition or sufficient for the purpose, and a new biomass underfloor heating system was added to produce ambient temperatures for the plants without impacting the integrity of the building. The finished bare metal design CGA03, meticulously created by our highly experienced pattern makers, echoes the original traditional Victorian grilles found elsewhere within the glasshouse complex and has since become Britannia’s signature grille. We are exceptionally proud to have been chosen and trusted to complete this award-winning project and are equally proud of our teams to produce it – from design, to manufacture, to installation.Frequently referred to as Cathedral, Ecclesiastical, or Victorian decorative floor grilles and as seen here, often placed over channels holding heating pipes, they provide a practical and decorative heating vent. Originally designed for churches they are increasingly popular in private houses, greenhouses, and commercial building developments. Our grilles can be ordered in cast iron or cast aluminium and finished in a wide variety of options.We also work in association with Gunning Heating, making decorative cast iron grilles that fit seamlessly into their underfloor trench heater units.  See our website for a full list of our grille designs and finishes or contact us to discuss your bespoke requirements.
