Installing a Geothermal Heating System in a Smaller Home
February 25, 2011
Q) We are building a new home in a rural subdivision, and are investigating the cost/benefit of geothermal heating and air conditioning. I recall hearing you recommending against installing geothermal for houses under 3000 square feet. Can you outline why? Thanks!
A) The simple answer to the cost effectiveness of ground source geothermal heating and air conditioning would be to look at the cost of drilling the wells. They can be drilled either vertically or placed horizontally if you have the property to do so. The geothermal contractor will have to visit the site so they’re able to accurately determine how deep the well loops need to be and if they need to drill vertically or horizontally. Geothermal systems have many different uses, ie: heating, air cooling, ice melt, pool heating, etc.
Please by all means have the quote done then you decide. It's a long term investment, and also an investment in the resale value of your home. It doesn’t hurt to have the appropriate information so you are able to make an informed decision.
