All residential r series units include matching drain connectors and connect easily to a 3 4 in.
Drain water heat recovery device. As warm water flows from your shower down the waste drain on its way to sewer the dwhr device uses heat exchange. The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10. This is achieved by a variety of systems called drain water heat recovery dwhr. The energy department estimates that energy losses in hot water amount to 80 to 90 a good argument for installing a drain water heat recovery dhr system.
1 illustrates a typical whole house gfx drain water heat recovery system dwhrs plumbed for highest efficiency as described in the original gfx patent u s. Thus it enters the water heater pre warmed and will take less heat energy and money to get it up to temperature. The r2 60 will save up to 30 on your water heating costs and is easy to install by any plumber and most do it yourselfers. The next generation of drain water heat recovery technology.
Leed third party etl safety certification nsf ansi std 61 copper part s prevent pinhole leaks black mold. Drain water heat recovery technology works well with all types of water heaters especially with demand and solar water heaters. Heat from the drain water is transferred to incoming water. It works by using outgoing warm drain water to pre heat incoming cold fresh water so your water heater doesn t have to work as hard.
They generally have the ability to store recovered heat for later use. In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing. Drain water heat exchangers can recover heat from the hot water used in showers bathtubs sinks dishwashers and clothes washers. We make it simple to save energy and money by recovering the heat in drain water.
With a drain water heat recovery system the cold water heading to the water heater first picks up some of that waste heat from the drain pipe. The power pipe captures much of this heat then recycles it to raise the temperature of incoming cold water.
