Drain Water Heat Recovery Unit

Fresh water line for 2 in.
Drain water heat recovery unit. The power pipe captures much of this heat then recycles it to raise the temperature of incoming cold water. This is achieved by a variety of systems called drain water heat recovery dwhr. R2 42 drain water heat recovery unit at 20 30 of home energy consumption water heating is the 2nd highest energy demand. Drain water heat recovery.
Power pipe r4 60 drain water heat recovery unit 1 800. Drain pipe and requires a vertical drain pipe length between fittings of 63 in. It recovers heat from your shower and uses it to preheat incoming cold water. Power pipe r3 66 drain water heat recovery unit.
They generally have the ability to store recovered heat for later use. Power pipe r2 120 drain water heat recovery unit. Drain water heat recovery save energy on water heating. At 20 30 of home energy consumption water heating is typically the 2nd highest energy demand.
Thermodrain is one of the most comfortable energy efficiency upgrades you can make in your home. 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. In a drain water heat recovery dwhr application falling drain water forms a thin film that rapidly imparts its heat to the colder pipe wall. A drain water heat recovery unit increases its heat potential the more drain water there is the system demands less energy.
Drain water heat recovery systems are an energy efficient technology that can reduce your water heater s energy consumption by up to 25. No maintenance required no moving parts. As warm water flows from your shower down the waste drain on its way to sewer the dwhr device uses heat exchange. All residential r series units include matching drain connectors and connect easily to a 3 4 in.
Drain water heat recovery systems up to 20 of home energy consumption comes from water heating which is the second highest energy consumer in the house next to space heating. The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10. Some of these devices may even store the water in a tank heating it while it is standby by flowing warm drain water in the bottom. It works even better when the incoming fresh water is already warm.
According to csa testing with the r3 60 performance is proportional to rated efficiency.
