PRODUCT PROFILES | HEATING, VENTILATION AND AIR CONDITIONING 42 BUILDING PRODUCTS | JANUARY 2018 Piping leaves Glasgow tower block feeling the warmth Rehau’s Rauthermex pipes have been chosen to provide ‘efficient and affordable’ heating to more than 300 social housing properties, as part of a major district heating project in Glasgow, where four tower blocks are being upgraded. SSE won the contract to design and install the district heating system in the tower blocks, replacing exsiting stoarge heaters, which were expensive and inflexible to the needs of the tenants. To reduce the pipe size and minimise heat loss, SSE designed a radial system with a central energy centre powered by 12 new commercial gas boilers. The heat from the boilers will be delivered to plant rooms in each tower block, and from there, the heat can be transferred to interfaces installed in individual flats. The Glasgow district heating installation required 75mm DUO pipework to be fitted and joined with Fusapex fusion joints. The fusion weld joints are chemical and corrosion resistant, extending the life of the installation. Steve Richmond from Rehau said: “This particular district heating project is a great example of how polymer pipework is a proven alternative to steel pipework.“ www.rehau.com/gb-en Providing home comforts at two retirement living developments Custom-specified heat interface units (HIU) for two retirement living developments in Southsea, Hampshire, and St Albans, Hertfordshire have been supplied as part of a solution jointly developed by McCarthy and Stone, the plumbing contractor and Uponor. Designed, specified and installed by GP Plumbing to McCarthy and Stone’s requirements, the units will help deliver maximum energy efficiency from the four 150kW and three 120kW gas boilers installed as a central plant. With a well-insulated airtight building fabric and a mechanical ventilation system with heat recovery, each development comprises one and two-bedroom apartments. Heating and domestic hot water is included in the residents’ service charge for their apartment. The HIU units were supplied customised to the requirements of each project, with isolation valves situated at the top of the unit ready for connection to the centralised plant heating network. Andy Burns, construction manager at McCarthy and Stone added: “The HIUs provided by Uponor answer our requirements for a high-quality specification while helping us to reduce operational costs by saving energy and providing a long-term, low maintenance solution.” www.uponor.co.uk Keeping warm underfoot this winter BEKOTEC-THERM from Schlüter is the patented hydronic underfloor heating solution with an ultra-low construction height. A screed height of 8mm above the studs of the panels is all that is required, resulting in quicker warm-up times as well as considerable material and weight savings in comparison to other wet systems. A building can also be put into use more rapidly as there is no need to wait weeks for the screed to cure before tiles are installed. BEKOTEC-THERM can be configured to work with Building Management Systems (BMS) and a number of variants suitable for retrofitting are available. Schlüter-Systems can also provide a full design service for all Bekotec-Therm installations. In addition to ceramic tiles and natural stone coverings, other coverings such as parquet, laminates or carpet can be installed in conjunction with the BEKOTECTHERM system. www.schluter.co.uk Ventilation design and specification for multi-occupancy buildings has reportedly been made simpler through an innovative approach by Gilberts Blackpool. The company is said to have been the first to develop a stock, single-unit hybrid solution focused on natural ventilation with heat recovery - its Mistrale Fusion System (MFS). The company’s approach has continued with the evolution of the system that now enables simple addition of extra elements. These include heating coils, filters, silencers, duct connection outlets and louvre transformation, plus a range of air volumes for warm up or purge ventilation, to supplement the standard airflow rates can be added. Roy Jones, technical director for Gilberts, said: “Using this modular approach makes it as simple as possible for the precise needs of each room to be met, in line with the latest F.O.S and BB101 requirements. “It means the MFS is retained as a standard, individual module to which bespoke parts are added in compliance with the architectural requirements, simplifying and accelerating the whole building services design, supply and installation process. www.gilbertsblackpool.com Fusing the options
