Rehau expands polymer district heating pipe range

Rehau expands polymer district heating pipe range

Rehau is now able to supply a polymer-based district heating solution for larger projects in the UK, thanks to an exclusive deal signed with polypropylene (PP-R) pipe manufacturer, Aquatherm Sales UK.

The deal will result in Aquatherm PP-R pipes of 200-315mm diameter being supplied exclusively in the UK through Rehau. This allows the company to meet increased market demand for significantly larger sizes of district heating schemes.

The Rehau RAUTHERMEX and RAUVITHERM PE-Xa ranges are available up to 160mm for district heating applications. In the past, this meant that any projects requiring pipes larger than 160mm were offered a steel – polymer hybrid solution, whereby the larger spine pipe would be supplied in steel and the smaller pipes coming off it would be produced in PE-Xa.

As a result of the agreement with Aquatherm Sales UK, the manufacturer can now offer PP-R spine pipes which can be used with its PE-Xa pipework. This fully polymer solution has many advantages for the customer as polymer pipes are very durable, require no expansion bends and do not corrode.

Steve Richmond, Head of Marketing & Technical, said: “Our sales team are being approached by customers who wanted a polymer solution for larger district heating installations. With the current size limit of PE-Xa pipes Rehau and Aquatherm Sales UK reached an agreement to work together to provide a solution combining our expertise in this field. They have agreed to exclusively supply the larger diameter pipes to us, and now we can offer more choice and tailored options to our district heating customers.”

Aquatherm GmbH too is a German company with a UK operation. Murdo MacDonald, Managing Director of Aquatherm Sales UK said: “We are delighted to sign this agreement with Rehau in the UK. We feel the two companies‘ strengths complement each other well with the many years experience we have of PP-R district heating pipes and we look forward to a successful partnership with them.“

Currently only around two per cent of the UK’s heat is supplied via heat networks. Last year the Government announced £320m of capital funding over the next five years to stimulate growth in the heat networks market and the first round of successful local authorities was announced in April 2017 when £24 million was allocated to nine projects.
