Category: Home Efficiency
Drain water heat recovery (DWHR) units reduce the amount of hot water needed in your home by up to 60% through recovering heat that would otherwise be lost down the drain. That energy is then used to preheat cold water going to the hot water tank.
Get Started
Hire a professional to retrofit a DWHR unit into existing vertical drains or request them on new construction projects.
