Drain water heat recovery systems use the heat from the wastewater of showers, sinks etc to be reused in another application in the building pumping it back into the domestic hot water tank for example.
These systems can recapture 60- 70 % of the heat lost through the drain water in a building.

Ircan plumbing and mechanical services can install all types of drain heat recovery systems. Reducing the energy load of your electricity bill, this system can be used in conjunction with on demand water systems or solar hot water systems.
