Savings expected is 35 roi is 2 5 years.
Drain water heat recovery system.
The thermodrain does not require maintenance and solids can flow freely through the thermodrain without the risk of blockage.
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.
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.
In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing.
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.
