RAUVITHERM: the ideal pipe for your commercial ASHP project
Author: Mark Chisnall
The summer holidays are ideal for schools, colleges and universities to undertake essential maintenance to improve their heating systems. Indeed, for many of our customers, using this time to progress to a greener heating system is a priority.
Going green is great for the environment, and here at Mibec, we have seen a massive influx of orders over the past few weeks to support this type of work. In July alone, we dispatched numerous orders nationwide to deliver to projects, including air source heat pumps (ASHP).
ASHP enclosures, typically located away from the building, are a key component of our efficient heating systems. They require underground district heating pipes to carry the low-temperature hot water into the plant room for distribution. ASHPs run on a much lower delta T than traditional heating systems, resulting in larger pipes to carry the medium.
When selecting the pipe for these heating systems, we recommend REHAU’s RAUVITHERM. Made in the UK, this cost-effective solution offers great flexibility, allowing the pipe to change direction in the ground, thus minimising joints, reducing labour time, and allowing trenches to be closed quickly. The Everloc jointing system, when required, is leak-free, with over 1 billion joints worldwide without any failures.
Why choose RAUVITHERM?
Flexibility for easy installation – excellent flexibility due to the corrugated outer jacket and closed cell insulation. This allows for rapid installation and the ability to easily navigate obstacles on site.
Robust HDPE outer jacket – withstands demanding onsite conditions.
Size flexibility – long coils of up to 300 metres are possible, allowing for faster and more cost-effective installations. Longer coils mean fewer accessories and connections, reducing parts and labour, the risk of leakages, and the installation time.
Excellent insulation – High insulating performance from closed cell cross-linked PE foam minimises heat loss.
Fully sealed design – The outer layer of foam is bonded to the outer jacket to prevent water ingress.
Leakproof – Uses leakproof REHAU Everloc compression sleeve technology.
REHAU has excellent stocks in their national distribution centre, and all the pipe coils are cut to customers’ specific lengths, minimising waste and speeding up installation.
At Mibec, we are REHAU’s number one independent authorised supplier in the UK, and we can help you determine the optimum pipe size for your commercial heat pump. We hold stock of RAUVITHERM from 25mm to 160mm. If required, larger polymer sizes are available in their PP-R range. Visit our website to find out more or call our expert team on 01782 959170.
