Drain Water Heat Recovery

Turn the waste heat going down the drain into valuable energy savings.

Drain Water Heat Recovery (DWHR) devices are silent, maintenance free energy savers that capture heat otherwise destined for the sewer, and transfer it to cold water coming into your hot water heating device. This results in less energy being required to heat your water to the desired temperature.

Rebates of up to $500 are available for the installation of a new DWHR device. Rebates will vary based on the energy savings modelled by a Participating Contractor for your project. Factors that impact the rebate are the device you choose, the flow rate of your shower heads and the number of showers which drain through the portion of the plumbing system where the DWHR device is installed. The following examples provide some estimates of how much money you can expect to get back in rebates—your contractor will be able to provide more specific details and walk you through the process.

  1 Shower 2 Showers
Small system (up to 42 inches) $83.13 $166.25
Medium System (42 to 62 inches) $148.75 $297.50
Large System (62 and up) $201.25 $402.50
