Recoup Heatdeck is a pioneering tray with an integrated wastewater heat recovery system (WWHR), suitable for new house build, bathroom upgrades or retrofit. The integral horizontal heat exchanger can reduce the energy required per shower use by up to 43%, reduce users’ energy bills and support the decarbonisation of UK homes. Heatdeck comes in 800mm x 800mm or 1200mm x 800mm with accessibility from above for complete peace of mind with no planned maintenance required. The tray has been designed to optimise efficiency through the management of the flow of water over the heat exchanger, partnering thermostatic electric or mixer showers.
