Heat pumps are not new, they've been in use for more than thirty years. Upward-spiraling energy costs and technological breakthroughs have made heat pumps a popular, sensible alternative to conventional heating and cooling systems.
A heat pump is an air conditioner that contains a valve that lets it switch between "air conditioner" and "heater." When the valve is switched one way, the heat pump acts like an air conditioner, and when it is switched the other way it reverses the flow of Freon and acts like a heater
A geothermal heat pump extracts heat from the earth through a series of pipes buried underground. It is said to be more efficient than the most common type of heat pump, air-source heat pumps, which transfers heat between your house and the outside. Geothermal heat pumps operate on the principle that, at a particular depth, the earth remains more or less a constant temperature throughout the year. In cooler months, it contains more heat than air and vice versa. The earth absorbs 47% of the sun's energy, over 500 times the energy that we need per year. This is a huge energy source that with the help of heat pumps, can heat homes and even provide hot water. Overall savings is about 30-70%!
