Are You Building a New Home?
Copper DX Geothermal Heat Pumps May Offer an Answer.
Earth coupled heat pumps take advantage of the fact that several feet underground the temperature is relatively constant, even when the temperature above ground is minus 20 or 120 degrees. Taking advantage of the temperature differential allows heat to be moved between the ground and your home rather than expensively generating heat or using conventional air conditioners to heat or cool your home.
This site will help you learn about the earth-coupled copper ground source heat pump systems and compare them with traditional heating and air conditioning systems.
