Passively Recovering Waste Heat Energy With Every Shower

Recoup Retrofit+

This compact, single walled WWHRS is easy to install, easy on the pocket and easy to maintain! As it’s name suggests, it’s ideal for retro-fitting in domestic and commercial properties. A very cost effective way to achieve efficiencies of up to 22%. The Retrofit+ waste water heat recovery system can be installed under baths with showers, shower trays or even be boxed in next to your drain. The system had impressive success through the Green Deal home improvement scheme up until the withdrawl in September 2015 but still provides the added benefit of adding towards the silver standard for Scottish Housing Association homes. Perfect for landlords, housing associations, hotels or home owners wishing to save costs on their hot water usage, this system is the must have upgrade for your property. When the cost vs benefits are weighed up, we are sure it will tick all the boxes.
