How big of a pond do I need for geothermal?

The lake or pond should be at least 1 acre (40,000 square feet) in surface area for each 50,000 Btu per hour of heat pump capacity. Another way to measure is to have a volume of water available that is the same volume as the structure being cooled or heated.

Can I install my own geothermal system?

There are 4 common types of popular geothermal systems. ... The type of system you will choose is dependent on the local topography and land or water space available. However, the most common and simplest to install is the horizontal ground loop or the well loop.

What factors affect the efficiency of geothermal energy?

Production well depth, geofluid temperature and mass flow rate are the parameters considered. An increase in mass flow rate is shown to increase both power output and efficiency.

How can a geothermal heat pump be used to produce domestic hot water?

For water heating, you can add a desuperheater to a geothermal heat pump system. A desuperheater is a small, auxiliary heat exchanger that uses superheated gases from the heat pump's compressor to heat water. This hot water then circulates through a pipe to the home's storage water heater tank.

How much does geothermal cost monthly?

The homeowner said he was paying $150/month for propane, and if we deduce the average geothermal kWh use it would be around $138/month, a savings of $12/month. In today's dollars, the price of geo is 1/3 the cost of propane, so he would save $3,000 per year.
