Mcquay International Geothermal Heat Pump 4 Ton Water-to-Water (Radiant Floor)
Because underground temperatures do not change and remain relatively constant year-round, a geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures.
Why are geothermal heat pumps more efficient than air source heat heat pumps?
The geothermal system cycles water from a well, pond, lake or river, or water piped through underground plastic tubing, to warm or cool the heat pump's refrigerant. Liquid such as water or an antifreeze solution is a much better heat transfer medium than air. Overall, the liquid medium for heat transfer is about 30% more efficient than air.
How many Types of Geothermal Units Exist?

Just wanted to let you know that the filter rack worked perfectly. My geothermal system is heating my house and the temperature last night was below 0 degrees. My house is over 3000 sq ft.and compared with oil I save at least $450 even though my electric bill for the month of December was $150 over what I paid last year, and it is less than the cost of heating with wood without all the mess and work. Needless to say I am very happy with my system. At some point, I will need to add some way to heat hot water (we are still using the old oil boiler until the tank is empty) and a small propane furnace to help the geothermal on the coldest days. I am thinking of and on demand hot water system but I would be interested in any suggestions that you might have.
