What is a “Split System” Heat Pump?

A split system heat pump is a year-round comfort system. In the summer it draws heat out of your home to keep it cool, and in the winter it draws heat from outside air into your home to keep it warm. Many heat pump installations have a booster electrical resistance heater that automatically supplements heat brought in from the outside. Outside air always has heat in it — even at very low outdoor temperatures. Like a central air conditioning system, it includes a compressor, a fan, outdoor coil, indoor coil and a refrigerant. The efficiency of Heat Pumps is rated using SEER (for cooling efficiency) and HSPF (for heating efficiency). A Heat Pump uses electricity as its power source.

The basic components of a heat pump system are:

  • An outdoor Heat Pump section
  • A matching indoor Air Handler or Gas (natural or propane) or Oil Furnace with coil
  • Ductwork to transfer the heated or cooled air throughout the home.

A geothermal heat pump can deliver heat through ductwork or a radiant floor system.  Geothermal heat pumps are the most environmentally responsible and least expensive system to operate when properly designed and installed.  Boucher Energy Systems, Inc. installs Bosch Geothermal systems and repairs many others.  If you have a geothermal system that does not perform well, we can be hired to evaluate your current system and recommend improvements.
