Drain Waste Heat Recovery System

The power pipe drain water heat recovery system is an effective way to reduce water heating costs by 20 to 40 and continue saving throughout the entire building lifecycle.

Drain waste heat recovery system.

According to csa testing with the r3 60 performance is proportional to rated efficiency. Horizontal drain water heat recovery dwhr system for main drain lines the ecodrain b1000 is the only drain water heat recovery system specificially designed for main drain lines. In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing. Heat from the drain water is transferred to incoming 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 efficiency of your water heating system goes up and your water heating bill. Water heating accounts for approximately 20 to 30 percent of household energy demand. Drain pipe and requires a vertical drain pipe length between fittings of 63 in.

This is a simple diagram of how a drain water heat recovery system works diagram courtesy of ecodrain. Non storage systems usually have a copper heat exchanger that replaces a vertical section of a main waste drain. It works even better when the incoming fresh water is already warm. How it works multi family applications.

Water heater intake water is preheated by circulation through a coil at the top of the tank. A drain water heat recovery unit increases its heat potential the more drain water there is the system demands less energy. All residential r series units include matching drain connectors and connect easily to a 3 4 in. It is the ideal solution for saving energy in single story homes homes built on crawl spaces and manufactured homes.

Reduce costs and emissions in commercial establishments. 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. 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.
