Geothermal Heat Pumps: 400% Efficient

Geothermal heat pumps are four times more efficient than standard heat pumps saving energy and saving you money!

What constitutes a heat pump?

A heat pump is any machine that removes heat from one area and moves it to another. You may be surprised but a number of household devices are actually heat pumps including refrigerators and air conditioning units. Refrigerators remove any existing heat from the inside and pull it outside using energy; this is why the back of your refrigerator is hot!

What makes a geothermal heat pump so efficient?

An air source heat pump utilizes the outside air which has a extremely wide range of temperatures. On the other hand, a geothermal heat pump uses the air from below the earth’s surface which remains at a much more constant temperature (between 45 and 65 degrees based on location).  A traditional air source heat pump uses energy to cool or heat the external air depending on the season making it less efficient.  A geothermal heat pump does not have to generate energy, it instead transfers heat from the ground.

How can the efficiency exceed 100%?

Many traditional heat pumps are 94% efficient.  This means that 94% of the energy is used to pull out the heat, but the other 6% is used to run the actual pump.  By transferring energy a geothermal heat pump becomes exponentially more efficient.  When a geothermal heat pump consumes one unit of energy to operate, it transfers 4 units of energy in return.  In other words, a geothermal heat pump has a payback rate of 400%.  This efficiency results in dramatic savings in energy bills, up to 70%!

    I love the site! I just want to know more about who owns it
    and who runs it. I have been in the energy game since the
    70s. I know how nasty it can get.
