REHAU Building Technology
District heating (heat networks) is the concept of one large centralised boiler instead of individual boilers. Heat is then transported via pre-insulated district heating pipes into each building. REHAU offer 2 pre-insulated pipes:
RAUVITHERM is the only PE-Xa district heating pipe manufactured in the UK which saves an estimated 29% on CO² emissions. Ideal for district heating, biomass, biogas and heat pump applications. Available in UNO 25-125mm and DUO 25-63mm.
RAUTHERMEX offers huge advantages over traditional steel pipework due to the speed and ease of installation. The high performance PU foam makes it ideal for large district heating over long distances where heat losses are critical. Available in UNO 25-160mm and DUO 20-75mm.

REHAU Reaches New Heights at South Quay Plaza
South Quay Plaza in Canary Wharf is set to be one of the tallest residential buildings in Europe when completed. REHAU’s RAUTHERM PE-xa underfloor heating pipe was chosen by Instacoustic to be specified and installed in a total of 685 apartments across 67 floors in the building, to provide underfloor heating with the Instacoustic cradle and batten system.
With over 25 years’ experience, Instacoustic are well known for providing innovative environmentally friendly products that help specifiers and developers with comprehensive sustainable solutions for effective sound insulation on new build, conversion and refurbishment projects.
Instacoustic’s patented acoustic systems are designed and manufactured to the highest standards and exceed, the latest building regulations to provide extremely high standards of acoustic control against the transmission of impact and airborne sound.
REHAU was tasked with engineering an underfloor heating system that would fit within the fixed structure provided by Instacoustic. Together, both brands created a support bracket and a pre-routed support panel for the underfloor heating that created very thermal transfer. In essence they developed a system that provided an effective, thermally efficient and dry installation that delivered on excellent acoustics for the building’s residents.
Matthew Miller, National Sales Director at Instacoustic said: “Close to five years ago we identified that underfloor heating with premium floor systems was something the market desired and we have seen massive success since we decided to venture into this area.
“In this dynamic industry, REHAU’s products and services definitely complement ours and it seemed like the perfect partnership for this project. South Quay is our first big project with REHAU and I am glad to say that it was a massive success.
“REHAU’s technical expertise is second to none and the information and support provided by them helped us to a deliver a system easily and efficiently, especially on a site level. As a brand, REHAU is quite competitive commercially and I believe their quality products at great price helped us win the project overall.”
REHAU has been supplying underfloor heating pipe for more than 50 years and uses the high-pressure peroxide method of crosslinking in manufacture, which was pioneered by the company. The pipework can tolerate extreme temperature and impact and will withstand pressure surges more effectively than pipe made from copper, steel or CPVC while also avoiding water hammer.
Renowned for its flexibility and durability, PE-Xa is a crosslinked polyethylene material which is achieved via a change in its molecular structure thereby chemically linking the polymer chains to form a three-dimensional network. Operating temperature and pressure ratings on PE-Xa pipes manufactured for underfloor heating applications include 6 bar at 70°C and short term temperature resistance of up to 110°C in case of malfunctioning safety equipment. All REHAU PE-Xa pipes always have minimum burst pressures way above normal operating pressures.
The product also boasts some environmental credentials which include an overall lower cost to the environment when compared to alternative piping options, with no chlorine being used in its manufacture. With smooth interior walls and excellent flow characteristics, pumping costs can be reduced and energy is saved to provide a faster delivery of hot water. Heat loss is also kept to a minimum and there is no condensation through pipes when compared to equivalent copper products
South Quay Plaza has been developed by Berkeley Group and was designed by Foster & Partners Architects. Consultants for the project were WSP. Situated in Canary Wharf, the building is a mixed use, sustainable waterside development.
Rehau - Fewer joints means time and cost savings for contractors
Fewer joints means time and cost savings for contractors
As pressure mounts on contractors and developers to keep up with increased demand for housing while remaining cost-effective, there is more need than ever for time saving construction methods, materials and solutions.
With space for plumbing systems often at a premium in new developments, modular components can reduce the need for time-consuming jointing work onsite, on top of the costs associated with large amounts of materials. These components can also afford contractors flexibility and adaptability in a multitude of different spaces and applications.
In response to greater demand for this type of quick-to-install modular plumbing component, polymer specialist REHAU has launched the new Smart Link plumbing manifold. Well-suited for uses in areas of limited space, such as within utility cupboards, its low cost and flexibility allows for quick, easy and effective plumbing system installation, saving contractors time and money when building new developments.
For example, when used in a point-to-point plumbing configuration, the Smart Link manifold allows for up to 70% fewer joints required compared with traditional branch plumbing. By connecting radiators, taps and outlets to the supply using piping from a central manifold, this point-to-point plumbing delivers fewer potential leaks and much faster installation time thanks to the reduction in joints required in the system.
Furthermore, the Smart Link’s nine individual outlet isolation valves, made up of four hot and five cold water valves, simplify and centralise all of the isolation points. Because of this, it requires no installation of additional isolation valves in the system, meaning contractors can enjoy further reductions in time savings and material costs.
“We understand that contractors and building services providers need to keep installation time and costs to a minimum,” said Steve Richmond, Head of Technical and Marketing at REHAU UK. “With the Smart Link plumbing manifold, installation time is reduced thanks to fewer components and joints being required, which also translates into lower costs for contractors.
“In addition, the flexibility afforded by the Smart Link will allow developers to adapt the plumbing system to fit any space within their development. We hope that this new component will be an invaluable tool for contractors and developers looking for flexible plumbing solutions.”
