All residential r series units include matching drain connectors and connect easily to a 3 4 in.
Drain waste heat recovery system.
Drain pipe and requires a vertical drain pipe length between fittings of 63 in.
The efficiency of your water heating system goes up and your water heating bill.
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.
This is a simple diagram of how a drain water heat recovery system works diagram courtesy of ecodrain.
Drain water flows through a spiral tube at the bottom of the heat storage tank.
Non storage systems usually have a copper heat exchanger that replaces a vertical section of a main waste drain.
According to csa testing with the r3 60 performance is proportional to rated efficiency.
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.
Heat from the drain water is transferred to incoming water.
Water heating accounts for approximately 20 to 30 percent of household energy demand.
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.
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.
A drain water heat recovery unit increases its heat potential the more drain water there is the system demands less energy.
How it works multi family applications.
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.
