Otherwise, you'll need a pond. If you don't have 1 of these 3 land requirements, you're out of luck.

2. Consider the up front cost. Yes, most homes can recoup the instalation costs of a geothermal heat pump in about 3 to 5 years, but some people simply don't have the cash in hand. A horizontal system can cost about $25,000 on new construction. Sometimes the disadvantages about geothermal energy begin with the wallet.
