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 system.
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.
Water heating accounts for approximately 20 to 30 percent of household energy demand.
The power pipe can dramatically cut water heating costs and reduce total home energy consumption by 5 10.
This is a simple diagram of how a drain water heat recovery system works diagram courtesy of ecodrain.
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.
Drain water heat exchangers can recover heat from the hot water used in showers bathtubs sinks dishwashers and clothes washers.
The thermodrain does not require maintenance and solids can flow freely through the thermodrain without the risk of blockage.
How it works multi family applications.
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.
Reduce costs and emissions in commercial establishments.
In a gravity film heat exchanger gfx drain water flows through a copper pipe that is wrapped in smaller diameter copper tubing.
Simple systems have speedy payback.
Laundry savings scenario using drain water heat recovery.
If you are building a new home installing a drain water heat recovery system during the building process rather than after the fact.
Savings expected is 35 roi is 2 5 years.
Drain water heat recovery technology works well with all types of water heaters especially with demand and solar water heaters.
High maintenance heat exchangers with filtration systems have been used for heat recovery in laundry systems.
