Discover how Drain Water Heat Recovery System can improve your home energy costs
Water heating accounts for 20% of the average
home energy consumption, and showering accounts for 50-70% of residential hot water energy
load so…
Why pay for heat only to let it go down the drain?
 Heat recovery is like getting heat for free – you have already paid
for it once, so why pay again when you could reuse that heat?
By recovering the heat going down your drain, you will use less new energy to heat your hot water. Plus reduce the amount of greenhouse gas produced.
How do drain water heat recovery systems work?
When warm water goes down the drain, it carries away valuable energy with it. Drain water heat recovery systems can recover
some or most of this valuable energy and use it to preheat cold fresh water.
This innovative technology is simple, long-lasting and has no moving parts.
The cold water coming into your house runs through a series of coils that are tightly
wrapped around your drain stack.
When someone in your family is taking a shower, the warm water that is going down the drain transfers its heat through the copper walls of the drain water heat
recovery unit to warm the cold water, before it goes into the water heater.
The heat is transferred, but the drain water never mixes with the fresh, and your
water heater uses less energy.
It’s simple and you will enjoy the savings for many years to come.
