Drain Water Heat Recovery
Drain Water Heat Recovery (DWHR) is the practice of recovering the thermal energy we throw away down our drain particularly during a shower.
Water is the most expensive natural element to heat and carries a significant amount of energy. Any hot water that goes down the drain carries away energy with it—as much as 80-90% of the energy used to heat water in a home. Drain water (or greywater) heat recovery systems capture this energy to preheat cold water entering the water heater or going to other water fixtures.
The Power-Pipe is a water to water heat exchanger designed for use with drain water.
