Drain Waste Heat Recovery System

According to csa testing with the r3 60 performance is proportional to rated efficiency.

Drain waste heat recovery system.

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. Thus it enters the water heater pre warmed and will take less heat energy and money to get it up to temperature. 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. All residential r series units include matching drain connectors and connect easily to a 3 4 in.

How it works multi family applications. Heat from the drain water is transferred to incoming water. A drain water heat recovery unit increases its heat potential the more drain water there is the system demands less energy. Drain water flows through a spiral tube at the bottom of the heat storage tank.

It is the ideal solution for saving energy in single story homes homes built on crawl spaces and manufactured homes. It works even better when the incoming fresh water is already warm. Non storage systems usually have a copper heat exchanger that replaces a vertical section of a main waste drain. The efficiency of your water heating system goes up and your water heating bill.

Water heater intake water is preheated by circulation through a coil at the top of the tank. 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. This warms the tank water which rises to the top. In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing.

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. 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. Reduce costs and emissions in commercial establishments.
