What is DWHR?

What is Drain Water Heat Recovery?

Answer this...when you take a hot shower, what happens once that HOT water goes down the drain and how do I reuse the energy? That is Drain Water Heat Recovery!

A "DWHR" can capture waste heat energy and be used to heat NEW incoming water, saving money & energy, as well as the life of your hot water tank. It also works well with Geothermal, Solar and Tankless (on demand) Water Heaters.

Relay Network Targets Multifamily Housing Upgrades Nationwide

Affordable apartment buildings are home to more than 10 million American households, making them a backbone of U.S. housing stock. They also waste a lot of energy.

The simplest methods involve the rerouting of gutters into an above ground rain barrel up to a complex system of catchment dishes, filters, pumps, ponds and…
