About Waste Water Heat Recovery Systems (WWHRS) market sectors

What is WWHRS?

WWHRS is the abbreviation of Waste Water Heat Recovery System. In the simplest terms a system or technology that uses the remaining heat from shower waste water to increase the heat of cold mains water coming into the system. Less energy is then used to heat the mains water to the required temperature.

Why use WWHRS?

WWHRS has been proven to provide a vital role in saving energy within both commercial and domestic properties. Compared to central heating that has many energy saving technologies in place, hot water has been an area where it has proven difficult to make significant improvements.

Commercial & leisure buildings

Recoup's range of WWHRS can make a dramatic impact on the showers used in commercial and leisure buildings. We are involved with some of the following building types:


  • Offices - more and more people cycle and run before or during their working day, meaning shower useage is very high
  • Hotels - clearly a high user of hot water through showering every day of the year
  • Student accommodation - with all inclusive bills, saving on hot water is a must
  • Leisure/sports clubs - high traffic with virtually users showering - helps with capacity and costs


We work with some of the largest M&E designers and consultants helping to advise how our WWHRS can benefit their buildings both through code and also through use.
