"mechanical heating cooling and refrigeration"

With a housing stock that dates from the 1900s to present day, Vale of Aylesbury Housing Trust provides affordable housing for more than 17,000 people living and working in Aylesbury and the surrounding villages of the Vale. After a successful, no risk, no obligation trial, it was clear that the Dimplex Quantum off-peak heater was a fitting choice for the Trust’s varying housing stock - delivering controllable heat on demand.

When a Vue Cinema on the outskirts of Doncaster needed a section of the asphalt flat roof refurbished as part of extension and maintenance works, a zero odour solution was required that would allow the building to stay open to the public throughout installation. A liquid waterproofing product was considered ideal to avoid the need for complex edge detailing associated with single ply or bitumen products around the plant.

Heated Lockers were the focus of Helmsman’s most recent project. We travelled up to South Kirby in Pontefract, Yorkshire to work alongside Triton Construction at the brand-new Innovation Hub at Production Park. Production Park is a unique support environment for the live events industry, uniting technology, creative spaces and education. Their newest venture is the brand-new Innovation Hub, with a large research studio with connected offices and teaching spaces. The new innovation hub features specialist equipment designed to support the live events industry as well as a business support programme focusing on assisting SMEs.In an area off the main entrance lobby, Helmsman installed a set of Wet Specification Heated Lockers. With a mix of 1, 2 and 4 compartments, these lockers are designed with a single or twin tube heater at the bottom of the locker, hidden within the locker stand, and perforations throughout to allow warm and/or damp air to circulate and escape the locker. Triton Construction requested a modern, heavy duty laminate finish for these heated lockers. The body of the lockers was manufactured from aluminium and powder coated in colour Ice, whilst we used Biocarbon’s Solid Grade Laminate in colour Elegant Grey for the locker doors, end panels and cladding. This laminate is a great choice as it is carbon neutral as well as being moisture resistant and easy to clean, perfect for a semi-public area such as this project. Our heated lockers can either come with a standard 3 pin power plug or can be available with a spur to wire into a fused switch. Triton construction requested a plug which was positioned on the end panel of the bank of lockers.We paired stainless steel numbers recessed into the doors with Lowe and Fletcher camlocks for a seamless finish to the lockers.  This option of lock is simple and cost effective, whilst also safe and secure.It was great to work with Triton Construction on this project and we look forward to hearing about the success of the Innovation Hub at Production Park in the future. If you have a similar project, or want to know more about our Heated Lockers, contact us today on 01284 530427.

Our team at Helmsman manufactured, delivered, and installed a variety of our Heated Lockers. There were 35 three-compartment Laminate Lockers to accommodate 105 people, as well as installing 28 Z Lockers to accommodate 56 people.The lockers were manufactured with wet specifications which means that the Laminate lockers are manufactured for an environment where there is humidity, which can also withstand rust. The lockers are manufactured with an aluminium and stainless-steel body and laminate doors.The specifications of the three-compartment lockers and Z lockers were to be 1775mm high, 298mm wide, and 450mm deep. Along with the lockers, the lockers were all installed with seat stands. The measurement of the seat stand was 300mm wide and 450 deep, the stands were powder coated in colour ‘Black’, to match the body of the lockers. Whereas the seating was in our standard slats of Ash Hardwood.The body of the Heated Lockers was powder coated in ‘Black’. The laminate doors were in the vibrant colour of ‘Ballerina’. The heated lockers were finished with Lowe & Fletcher Nimbus in ‘Black’ which is a great choice as it secures personal belongings, along with many benefits such as having a collection of user modes such as public, private, or technician mode.

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. The unique design and architecture of Royal Winchester House creates a striking and impressive presence from the ground floor retail spaces up to the luxury penthouse levels.Royal Winchester House has been built for the private rental market and the development is being managed by Chancellors estate agency. The apartments benefit from high standards of insulation and air tightness. In addition to the NIBE heat pumps, the whole development has been fitted with a biodigester for the repurposing of food waste, as part of reducing waste sent to landfill and to add to its sustainability.

A project to install a communal heating system at low rise flats and maisonettes at Bretton House and Sanders Way, in the London Borough of Islington, is using bespoke metal pipe boxings to conceal external pipework.The more efficient heating system was installed as part of Islington Council’s ongoing cyclical repair programme, which assesses all properties on a 7 to 10 year cycle to establish where improvements need to be planned & implemented.The Pendock casings are manufactured from 2mm thick corrosion resistant aluminium and incorporate a brown PPC finish to integrate with the brickwork and provide a consistent finish to the project. The use of aluminium not only improves weather resistance, but also adds tough protection to the external pipework.

After moving from busy Stockport in readiness for retirement, accountant Susan and husband Philip, a Manchester University academic, replaced the oil-based heating system at Willow Cottage with a Daikin Altherma high temperature heat pump. 

application area: commercial gas heatinguse type: condensing gas boilersproject scope: line commercial freestanding chimney for condensing operationadded value: corrosion-resistant, air-tight and waterproof finishBackgroundThe combustion gases from the school's boiler room are exhausted through a freestanding 28-metre brick chimney. The structure was not suitable for the wet operation of condensing boilers. FuranFlex-25 Black was the chosen lining material.The new boiler plant required a 500mm diameter flue liner but the chimney could not accommodate a rigid liner this size. A FuranFlex25 Black liner was therefore specified as it expands into the rectangular flue shape when inflated with steam.Statement of workFuranFlex25 comes as a folded and soft tube. Inflating with steam irreversably hardens the liner fixing it in place. Within a few hours of steaming the liner was ready for connecting to the boilers. The appropriate adaptors/terminals were fitted making the chimney ready for operation.

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.

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.

A 35 sq.m end-terrace house in Gloucester is a showcase for greener heating. Preparing for a new tenant, landlord and heating specialist Craig Vernon replaced the 1990s all-electric space heating and hot water systems with a modern, greener solution.

Project BackgroundHoe Bridge School is an independent co-educational pre-prep and prep school in Woking, Surrey. The sports hall had been heated by an old radiant system supplied some 35 years ago. The old system was past economical repair so the school decided to invest in a brand new radiant heating system. Contractor, ABS Ltd had over the years maintained the facility, so the school looked to them for advice on replacement equipment. Powrmatic were approached by ABS Ltd and undertook a thorough survey of the sports hall, with a view of replacing the old system with a new Powrmatic SRP – PCV continuous radiant tube system.Project SolutionAlthough the concept of the new heating system is very similar to the old one, there are sound reasons for the like-for-like type replacement. Radiant heating in sports halls is well established as it provides an environment of uniform heat coverage without stuffiness where sports activities can be performed in complete comfort.The new Powrmatic SRP – PCV continuous radiant tube system comprised two radiant branches, each 22m long, down the length of the hall, each branch containing 2 x PCV 23kW burners, all feeding to a vacuum fan to extract the products of combustion. This arrangement virtually mimicked the original layout to reduce the installation time and costs.Project ResultGas fired continuous radiant tube heating is a proven type product being the most appropriate solution for the challenge presented by sports halls, maintaining comfort levels whilst minimising fuel usage and carbon emissions.The SRP-PCV system combusts fuel at the point of use and has the capability of modulating down to 60% of high fire whilst maintaining efficiency but reducing fuel consumption. The Powrmatic SRP-PCV system is designed and manufactured in accordance with BS EN 17175:2019 for Multi-Burner Systems and incorporates a patented burner metering device.The Powrmatic SRP-PCV & PCV+ systems have been validated following review against government approved high performing energy efficiency criteria, with a Seasonal Space Heating Energy Efficiency (SSHEE) of greater than 90%, thus allowing inclusion onto the ETL (Carbon Trust, Energy Technology List). This high efficiency reduces energy usage, operational costs and carbon emissions.

The installation of Grant heat pumps was part of a wider redevelopment programme which has transformed the space to maximise its potential while also reducing carbon emissions.

Innovative Solutions to Common ChallengesThe StayCity Hotels project was one in which Umbra's unique motorisation options were brought into play in a major capacity.The main challenge at the time was that motorised blinds were catching on objects within the room such as furniture and other objects obstructing the blinds mechanism. This was causing damage to the blind system themselves and meant a lot of downtime and maintenance cost. This was solved by a unique obstacle detection solution that Umbra offers, meaning that the blinds would stop when coming into contact with an outside object.The wide range of fabric options Umbra offers also helped greatly in this project. A fabric with high heat control properties meant that over the entire hotel, large savings could be made on heating and cooling costs. With sensors within the blinds also being able to communicate with the BMS, helping further with heat control and therefore energy efficiency.This is where Umbra's unique obstacle detection motors came into play, whereas before an obstacle would have been met with the force of a blind trying to close despite being unable to, now the smart sensors detected the obstacle and brought the mechanism to a swift halt, saving the obstruction from damage or wear.The full blackout KuroLok blinds also go a long way in quality of sleep for the residents of the hotel, blocking all light and creating a private environment greatly heightened the customer experience.The wide range of fabric options Umbra offers also helped greatly in this project. A fabric with high heat control properties meant that over the entire hotel, large savings could be made on heating and cooling costs.

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

ngineer puts greener heating solution to the test for comfort and economy 

A Dimplex air source heat pump forms part of the award-winning energy credentials at a ‘Superhome’ designed to showcase the energy savings that can be made using grants and relatively low-cost improvements.

A Uflex underfloor heating system consisting of fifteen zones has been installed as part of a barn conversion project in Thirsk, North Yorkshire. Here, we talk to Oliver Carter Plumbing and Heating, the G1 installer who completed the installation, to discover how they found working with the new Uflex underfloor heating range from Grant.

application area: commercial heatinguse type: industrial condensing boilersproject scope: preserve rectangular flue shape and maintain lined diameteradded value: quick and efficient installation with minimal downtime and disruption to the building structureBackgroundTwo new high efficiency condensing boilers fitted into the basement of a nine-story office block (Dublin Civic Offices, Ireland) using two separate brick lined chimneys that rose through the nine floors and exited on the rooftop.The brick chimneys posed a problem as the chambers measered 300mm x 450mm no standard 350mm flue liner would fit. Due to the pliability of Furnflex, the liner was able to take up an oval shape in the chamber giving it the full 350mm required. This building is an extremely busy high-profile office block therefore minimum disruption to day to day business was required.Statement of workFollowing an onsite survey, Furanflex was deemed the ideal solution to line both chimneys. The installations were carried out over two weekends, one for each chimney, with no disruption to the office operations. The project completed on time and within budget.

Contour recently completed an extensive project for a care home in Southern England, entailing the surveying, supplying, manufacturing, and installation of 47 LST radiator covers and 100 meters of pipe boxing. The new installations not only brought the care home up to safer surface heating standards but also ensured accessibility for cleaning and maintenance, crucial for infection control.Prior to the upgrade, the care home faced various challenges, including poor access for cleaning and maintenance, exposed pipework posing a burn risk, and aesthetically displeasing rusty covers. Dust build-up, a known health hazard, was a significant concern due to its potential to cause respiratory issues and spread infections among vulnerable residents.Contour addressed these challenges by installing DeepClean LST radiator guards with patented quick-release hinged doors for easy cleaning. These guards also featured BioCote® protection to combat bacteria and open-ended shoulders to minimise dust traps. Additionally, pipe boxing was fitted to conceal exposed pipework, reducing the risk of scalding.The results were transformative, providing the care home with a safer heating solution while significantly reducing infection risks and dust-related issues. With improved access for cleaning and maintenance, the care home can now better manage infection rates and maintain a hygienic environment for its residents. Moreover, the disposal of previous radiators was carried out responsibly, ensuring a complete and sustainable upgrade process.

The company helped to ensure residents in Arrowfield Estate could access maximum energy savings and reduced energy bills.

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

Hexham and Northern Mart is an auction house in Hexham (25 miles west of Newcastle), specialising in the sale of livestock and cattle to farmers across the North East of England. The business decided it was time to replace its old gas-fired heating system with a more sustainable alternative – one that would not only reduce energy consumption and running costs, but also earn additional income through the Renewable Heat Incentive (RHI). Minimising impact on day-to-day operations during the transition was another key consideration. Managing director Robert Addison tasked renewable energy specialist and NIBE Pro Installer Calibrate Energy Engineering with finding the right solution to meet the heating and hot water demands of the 112,050sq ft building.The SolutionThe team at Calibrate specified, designed and installed a 300 kW renewable heating system made up of five 60 kW NIBE F1345 ground source heat pump (GSHP) units. They paired this with a 50 kW solar PV array, fitted to the roof of the main pen area, which partially powers the NIBE GSHP system. The in-ground heat collectors required for the GSHP were laid in the fields around the buildings, with the controls units sited in a prefabricated plant room to the rear of the premises. The installation took just three months from start to finish, and during this time it was business as usual for Hexham and Northern Marts.ResultsDocked together in a cascade for greater output capacity, the five NIBE F1345 GSHP units now meet 95% of Hexham and Northern Marts’ 394,000 kW/h annual heating and hot water demand. Meanwhile, the 50 kW solar PV array generates enough free electricity to offset a significant 50% of the power needed to run the GSHP system. Hexham & Northern Marts is set to make a 236% return on investment – reaping an estimated £862,000 in energy savings and commercial RHI payments over the next two decades.Customer Testimonial“We couldn’t be happier with our new renewable heat and power sources. As well as delivering instant reductions in energy usage and subsequent savings on heating bills, the NIBE GSHP solution is providing us with a steady stream of income for the next two decades, thanks to the RHI. The power produced by the solar PV panels is an added bonus, and makes running the heat pump system even more cost-effective.“As a result, we’re expecting to see returns of more than double our original investment over the next 20 years – which is absolutely invaluable from a business point of view. Not only this, but we’ve got an efficient, reliable renewables setup that’s fit for the future, and will continue to deliver ongoing savings for years to come.”Robert Addison, managing director, Hexham & Northern Marts

Mark Lewis’s newly self-built two-bedroom cottage for his retired parents has a low temperature heat pump at the centre of an eco-friendly lifestyle design for maximum comfort, economy and efficiency.

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.
