The thermodrain does not require maintenance and solids can flow freely through the thermodrain without the risk of blockage.
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.
Laundry savings scenario using drain water heat recovery.
At 20 30 of home energy consumption water heating is typically the 2nd highest energy demand.
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.
Water heating accounts for approximately 20 to 30 percent of household energy demand.
If you are building a new home installing a drain water heat recovery system during the building process rather than after the fact.
How it works multi family applications.
They generally have the ability to store recovered heat for later use.
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.
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.
High maintenance heat exchangers with filtration systems have been used for heat recovery in laundry systems.
Simple systems have speedy payback.
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.
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.
Drain water heat exchangers can recover heat from the hot water used in showers bathtubs sinks dishwashers and clothes washers.
This is a simple diagram of how a drain water heat recovery system works diagram courtesy of ecodrain.
The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10.
