Recycling Waste Energy in the Home

I was researching eco-home products and came across this drain water heat exchange, manufactured by Watercycles Energy Recovery Inc. - a Saskatchewan company.

The big pipe is the home drain and the wrap-around tubing connects the cold water supply line to your hot water tank supply point.

You have a hot shower, the hot water heats the drain and passes the energy to the tubing, which pre-heats the water before it enters the hot water tank - recycling energy.

What a great idea. There are many little things we can do to conserve energy.
