Like most things, the cost of the whole thing is the bottom line deciding factor. But direct initial costs cannot be the only comparison. Geothermal systems will usually cost more to install initially, but will easily pay themselves off over time just in money saved from cheap operation. The typical payback period we are seeing is usually 3-6 years, depending on your situation.

Huge federal and state discounts are available specifically for these systems, and when paired with a renewable energy loan, can potentially cost you no extra money per year to install and heat with a geothermal system, AND pay back the loan. All of that for the same cost of just heating your house with a conventional system.
