‘Going Green’ seems to be a topic on a lot of minds lately. I have always been fond of using the available energy we have to maximize the comfort in our homes and maximize the long term dollar in our pocket. This is the geothermal heating and cooling article!
There has been a lot of focus on Solar lately as groups like Enphase build smart charge controllers for your panels, solar panel costs are coming down, installation is getting easier and there are many tax-advantaged incentives for installing solar in your home.
I don’t often see much regarding tapping into the huge thermodynamic heat bath we have sitting right under our houses! Most geothermal heat pumps for homes have nearly double the lifespan of modern heating and cooling equipment according to many manufacturers, but it also takes significantly less power to operate a geothermal heat pump than it does to run other traditional heating like forced air with an electric heat pump or an electric baseboard system.
Geothermal installation may be suited better to new buildings as piping must run either vertically or extend horizontally from the base of your home into the heat battery of the earth. Older homes may require additional costs to retrofit as additional work in the slab may be necessary. The heating and cooling potential for your specific climate does change, but all areas across the United States see a benefit. According to Energyhomes.org, the payback period is between 2 and 10 years. A system that requires vertical duct-work deep beneath your home will have more labor associated than a system installed with a horizontal trench.
So if you are interested in learning more, I would check out energyhomes.org and talk to a local supplier of geothermal installations. Not only will you have a system that uses 40-60% less energy than a traditional HVAC solution, it also helps you sleep better night knowing you made a change that has a lower environmental impact in terms of fossil fuel generation from the electric company and it will give you money back in your wallet to put towards your retirement!
