Geo-Exchange
Geo-Exchange Heating and Cooling
Geo-Exchange or ground source heat pumps are able to heat and cool buildings just using the constant temperature of the ground which exists 10 feet or more below the surface. Notice that this will not produce power but it can easily heat and cool a building.
To the left is a picture of a cabin getting the holes drilled for their geo-exchange system in 2002. We drilled 3 holes to about 350 feet each to provide heating and cooling to this 7 bedroom cabin and there have been no maintenance costs to date. The system does use BC Hydro electricity to circulate the glycol but it costs less than $50 per month for this and it's renewable hydro electricity.
This cabin would have been spending about $6,000 per year in propane costs to heat and cool to the same level. This system has already paid for itself twice over. This cabin is in Invermere, BC where there is no natural gas available so that leads to the easy payback. Contact us if you want us to give you a free estimate for a project like this.
