During every shower, litres of warm water disappear down the drain, and with that, valuable energy contained in the heat is lost. Our solutions capture this heat and reuse it.

After the warm water passes through the drain, it enters the shower wastewater heat recovery unit. Spiralling down the heat exchanger on the inside, whilst on the outside cold water flows in the opposite direction, the heat of the wastewater is transferred to the incoming cold water. In this way, the demand of the water heater is reduced, resulting in lower energy consumption. Typically, cold water temperatures of 10–12°C are preheated by the WWHR system up to 25–28°C.

Additional benefits include saving energy, saving costs, reducing CO₂ emissions and increasing shower comfort (enhanced capacity).
