Drain Waste Heat Recovery System

This warms the tank water which rises to the top.

Drain waste heat recovery system.

Drain pipe and requires a vertical drain pipe length between fittings of 63 in. Reduce costs and emissions in commercial establishments. Heat from the drain water is transferred to incoming water. Thus it enters the water heater pre warmed and will take less heat energy and money to get it up to temperature.
