Is the cost of drilling for Geothermal systems not feasible?
Great question, and the answer is yes, geothermal heating systems can be efficient in cold climates, but as for recouping cost, that’s a toss up. Geothermal heating systems are a tough one for us to recommend people do, or to dissuade them from doing, because using the stable temperatures of the ground and running that throughone of the best heat pumps for heating and coolingbuildings and houses, is a very sustainable and low carbon way to heat and cool a home. You can find a pretty detailed breakdown on this page –
Is geothermal heating (GSHP) worth the investment for homes?
这里有一页对比effectiveness of air source heat pumps (ASHP) and ground source heat pumps (GSHP), which was done in a similar climate to Ottawa at the Living City Campus just outside of Toronto.
地热系统会降低一部分供暖成本,所以安装成本是否会为房主提供合理的投资回报,实际上是由房屋的热负荷和现有的账单决定的。The times it for sure makes sense is when there is a very large footprint of a new home or a very poorly-insulated and leaky building envelope of an older home.
