So, how much will it cost me to operate a geothermal system?
Comparing The Cost of Heating Fuels (see below) will show that heating with a petroleum product or electricity will cost approximately $40.00 for a million BTUs. Geothermal will cost anywhere from one third to one quarter of this amount. A few well designed systems might even cost only one fifth the cost of electric or oil heating. What about the cost of operation in a few years, like in 2020? Well, it is anyone’s guess, but Green Mountain Geothermal has put forward our own projection based on some recent past history and the simple fact that petroleum is a limited resource with a rapidly increasing consumer base. If the price of oil increases 8% per year, it will cost $10 per gallon by 2020. If electricity increases at 4% per year, then it will cost $ .22 per KWH in 2020. Hopefully, increasing generating capacity in Vermont will temper any increase.
What will it cost to heat my house? That all depends on how many million BTUs you need per year. The better insulated your house, the lower your heat load and the lower your annual cost will be. In fact better insulating your house may even reduce the size and cost of the geothermal equipment we need to install. If you have an existing house, you can do your part by getting an energy audit, and investing in energy conservation.
It is the goal of Green Mountain Geothermal to provide its customers with the most efficient geothermal system possible. In most cases we recommend ClimateMaster geothermal equipment coupled with a Standing Column Well (SCW). A properly constructed SCW can furnish not only the highest input temperature throughout the heating season, it can also be used as the domestic water supply for the house.
