Waste Water Heat Recovery involves harvesting the heat that goes down the plughole after baths and showers before it disappears down the drain. Our highly efficient units capture over 50% of the heat that was in the original shower water; using it to preheat your shower.
The pre-heated water then supplies the mains cold feed to the shower or the Domestic Hot Water (DHW) heater. The DHW heater could be an Unvented hot water cylinder, Combination Boiler or a Thermal Store/Buffer Tank (mains fed).
We have a range available that is suitable for retrofitting and newbuilds!
These units cut hot water consumption significantly at low cost so should be one of the first things to install even before Solar Thermal! These units are currently benefiting from a £60 Cashback under the Green Deal!
