Drain Water Heat Recovery (DWHR)

Every time you shower, you lose more than just water down the drain. All that energy used to heat the water to the desired temperature is lost as well. With a ThermoDrain drain water heat recovery (DWHR) device from EcoInnovation, you can recycle that energy.

DWHR captures the latent thermal energy lost down the drain and uses it to heat water before it hits your hot water tank.

Using a DWHR system:

Saves you money and lightens your ecological footprint by recycling energy
Gives you more hot water by better maintaining your hot water tank’s heat
