When your geothermal system is installed and operating, you have a fully integrated, single-source home energy system. There is no tank to fill and only one energy bill to pay. A single unit provides both heating and cooling. And, you have the peace of mind that comes from a totally combustion-free home.

Savings

To compare heating systems (apples to apples) you need a common denominator. We have choosen to use “1 million BTUs” because many homes use between 45,000 – 85,000 BTUs per hour on a very cold winter day, which is just over a million BTUs per day (about 125,000,000 BTUs per year). Because each system uses a different fuel type we need to know how many BTUs a unit of fuel contains (A). Then, using efficiency ratings of each system (B), you can calculate the number of units required to create 1 million BTUs (C), which is used to compare costs (see calculator/next tab).

Heat Pump efficiency is measured as Coefficient of Performance (COP). For instance a baseboard electric heater has a COP of 1 (it is 100% efficient). Geothermal Heat Pumps in the Northeast have COPs of 3.4 or higher (depending on system design and performance).
