The ground naturally absorbs 50% of the Sun’s energy and with pipes which carry liquid placed in a loop design underneath the ground it will naturally become heated until they reach your heat pump.

How well does geothermal heating work?

Geothermal heating is an energy efficient method of heating and cooling and on average is 400% more efficient than traditional oil or gas furnaces which typically max out at about 75-98% efficiency.

How warm does geothermal heating get?

Geothermal heating systems will deliver warm air and not hot air. If the room temperature is around 70℉ the average air temperature be at around 90℉-95℉ from a geothermal heating system.

How cold can geothermal HVAC get?

Geothermal Heating Loop Design

  • Closed Loop: Most geothermal HVAC systems circulate refrigerant or water through a closed loop of plastic or copper pipes inside walls or underneath floors. 
  • Open Loop: Geothermal systems with open loops use water from a well, nearby lake or pond and circulates between the pipes and the water source.
  • Horizontal: Horizontal geothermal HVAC systems usually use closed loops underground in horizontal trenches.
  • Vertical: Vertical systems have pipes inside holes that are hundreds of feet deep and only a few inches wide so it won’t disturb your landscaping.

Do geothermal systems run all the time?

A geothermal heating system will typically have a longer run time than natural gas or propane in order to achieve maximum comfort. 

How long do geothermal systems last?

Geothermal heating systems that are indoors will typically last about 25 years and ground loops will last more than 50 years. This can be a really big advantage as conventional furnaces and AC units will typically last for around 15 years or less. 

How do you maintain a geothermal system?

When it comes to maintaining geothermal heating systems there ar several points to consider. First, consider using the right kind of thermostat such as wired and programmable ones. Secondly, change the air filter once a month in order to avoid obstruction of airflow, make sure that the filters are rated to handle the system. Thirdly, check the condensation pans for standing water and clear the drains of any blockages. Make sure to rinse the drain annually with a diluted bleach solution in order to keep it flowing freely. Fourth, make sure to close any vents in the home and keep an eye out for any debris or blockages. If there is any ductwork make sure to repair leaks with regard to tears, gaps or punctures. Fifth, get familiar with the indicator lights and system accessories as can be referred to with your owner’s manual. Lastly, schedule seasonal maintenance with your local geothermal heating professionals as they will be able inspect the system thoroughly and check the refrigerant levels, electrical connections, and conduct other maintenance duties as needed.
