Drainwater Heat Recovery Systems - Any hot water that goes down the drain carries away energy with it. That's typically 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. |
