Drain Water Heat Recovery System

They generally have the ability to store recovered heat for later use.

Drain water heat recovery system.

In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing. How it works multi family applications. The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10. At 20 30 of home energy consumption water heating is typically the 2nd highest energy demand.

Heating water accounts for up to 20 per cent of a home s energy use making it the second highest energy consumer after space heating. The thermodrain does not require maintenance and solids can flow freely through the thermodrain without the risk of blockage. Savings expected is 35 roi is 2 5 years. Drain water heat recovery systems have an extremely long product life 30 plus years so it may still be beneficial to install the technology right now if there will be more occupants showering in the future.

Drain water heat exchangers can recover heat from the hot water used in showers bathtubs sinks dishwashers and clothes washers. Water heating accounts for approximately 20 to 30 percent of household energy demand. This is a simple diagram of how a drain water heat recovery system works diagram courtesy of ecodrain. Drain water heat recovery technology works well with all types of water heaters especially with demand and solar water heaters.

Reduce costs and emissions in commercial establishments. 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. If you are building a new home installing a drain water heat recovery system during the building process rather than after the fact. 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.

Drain water heat recovery systems capture the heat from water going down a drain typically the shower and use it to heat cold water entering your water heater. Simple systems have speedy payback.
