If it’s time to upgrade or replace your HVAC system, consider installing a heat pump for all your indoor comfort needs. Heat pumps lower the cost of heating your home by using the ambient heat of the air or even the Earth to maintain a comfortable temperature inside. Additionally, a heat pump provides heating in the winter and cooling in the summer to eliminate the need for a separate furnace and air conditioner in your home.
How Air-Source Heat Pumps Work
An air-source heat pump works like an air conditioner in reverse to provide more efficient heating in the winter than an electrical furnace system. Air-source heat pumps work by drawing outdoor air over copper coils filled with a refrigerant solution. The refrigerant absorbs heat from the air and transfers it to another copper coil inside your home, which releases the heat for distribution through your home via your ducts. However, if the temperature outside falls below 40 degrees Fahrenheit, air-source heat pumps lose efficiency and a secondary heating solution may be required.
How Ground-Source Heat Pumps Work
Rather than drawing heat from the outside air, a heat pump can instead draw heat from the Earth. Although the surface temperature of the Earth may change, the temperature at a depth of ten feet below ground is a consistent 57 degrees Fahrenheit. A ground-source or geothermal heat pump utilizes a loop of buried pipe called a heat exchanger. Water or a refrigerant liquid is circulated through the heat exchanger to draw heat from the Earth and transfer it indoors, where it is sent through your ducts by an air blower to heat your home. Currently, the installation of a geothermal heat pump qualifies for a personal tax credit with a rebate amount of 30%.
