Waste Water Heat Recovery for Showers

Non Residential

Commercial & Leisure Buildings

Recoup’s range of WWHRS can make a dramatic impact on the showers used in Commercial & 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 usage 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
  • WWHRS can also be used towards compliance ratings with SBEM & BREEAM

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 through use. Contact us for advice, support or meeting requests.

How IT Works

Around 85-90% of shower heat energy goes down the drain. Waste Water Heat Recovery for Showers (WWHRS) extracts the heat from the shower waste water and transfers it to the cold feed of the shower, and / or the water heater for the property. This reduces the demand for hot water whilst showering which saves energy and household costs.

Vertical WWHRS

Waste shower water flows through a copper heat exchanger, with the cold mains water flowing around the exchanger.

Horizontal WWHRS

Waste shower water flows over a copper heat exchanger, with the cold mains water flowing through the exchanger.

System A installation method is shown above where preheated water is sent to the water heater and the cold side of the shower, providing the highest efficiency and greatest savings. System B sends the preheated water to the shower only, used for easy retrofits, upgrades, and for second systems in a property which have to be System B.

Easy to retrofit and saves around 30 to 40% of the energy per shower use!
