Drain Water Heat Recovery

Thus it enters the water heater pre warmed and will take less heat energy and money to get it up to temperature.

Drain water heat recovery. The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10. Up to 30 of savings on your energy bills and a 2 year payback safe robust. Rheem brass service valves for tankless water heaters. 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.

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. Drain water heat recovery dwhr technology can reduce water heating costs by up to 40. This process can be used for your home apartment condo business or many industrial processes using heated water.

Drain water heat recovery systems capture lost heat from hot water going down the drain and uses it to pre heat cold water entering your water heater as illustrated in the diagram to the right. Drain water heat recovery unit. The result is less energy is needed to heat water to the desired temperature. 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.

At 20 30 of home energy consumption water heating is typically the 2nd highest energy demand. Drain water heat exchangers can recover heat from the hot water used in showers bathtubs sinks dishwashers and clothes washers. Heat exchangers are made from solid copper so they are durable and there are no moving parts to wear out. This is achieved by a variety of systems called drain water heat recovery dwhr.

Zypho is a patented concept of shower water heat recovery. 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. Drain water heat recovery is the process of recovering part of this valuable energy from the warm water and using it to preheat your incoming cold fresh water. This electric energy savings in turn translates into a reduction in greenhouse gas emissions by up to one ton per year.

The efficiency of your water heating system goes up and your water heating bill goes down. In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing. They generally have the ability to store recovered heat for later use.
