Geothermal F.A.Q.s

Questions? We've got the answers.

What Is a Ground Source Heat Pump?

A ground source heat pump (GSHP) and a geothermal heating and cooling system are the exact same thing. Geothermal systems are also referred to as ground source heat pumps because they use ground source energy (stored solar energy) to heat and cool homes.

Does Geothermal Work With Solar Panels?

Geothermal is actually the best heating and cooling system to have if you're interested in installing a PV solar system for your home or building. Since geothermal dramatically reduces the amount of electricity needed, your solar system should easily be able to power your whole home if sized correctly.

See how you can combine solar and geothermal on our blog.

How Does Geothermal Move Warm And Cold Air Throughout My Home or Building?
Forced Air & Radiant Heating/Cooling
Heat can be brought into or removed from the home or building in two different ways. The most common method, especially for existing homes, is with forced air through a series of ductwork. In this case, a blower is used to pull air in and once heated or cooled, the air is pushed back into the structure through ductwork. The other method used to disperse heat powered by geothermal is called radiant heating. In this case, hot water flows through pipes under the floor of the structure. This allows the desired temperature to radiate throughout the room evenly, so it's known as the most comfortable type of heating. 
Can Geothermal Be Used To Heat My Pool?

Yes, geothermal can be used to heat your pool year round. This is a very efficient way to keep your pool comfortable. You'll see a few pictures here of a home that has a pool heated by geothermal. 


I Have A Traditional Heating And Cooling System. Can I Still Install A Geothermal System?

Absolutely! Geothermal can be installed in several ways depending on your needs. A hybrid system would supplement your existing traditional system if your furnace is still in good condition and you live in a particularly cold area. In this scenario, the geothermal system provides 90% of your home's heating requirements, and the traditional system turns on when the outdoor temperature reaches a certain low temperature. Geothermal systems can work on their own in very cold temperatures, but when paired with a traditional system, this combination can create the perfect solution for the most efficient heating.

Geothermal can also be installed to completely replace your traditional system, which is usually the most efficient solution. In either scenario, the ground loop will need to be installed to make geothermal work for you.

How Long Does A Geothermal System Last?

There are two main components to a geothermal system. The ground loops, which are installed underground, have an indefinite lifespan (100 years plus). This part of the system should only need installed once. The second part of the system is the heat pump unit, which is installed indoors. The average lifespan of a geothermal unit is 25 years (many last beyond this), which makes its longevity superior to a traditional heating or cooling system that has an average lifespan of only 15 years. If a ground loop has already been installed, the indoor part of the system can usually be replaced with no more work or expense than a traditional system.

What Makes Geothermal The Most Economical and Environmental Heating And Cooling Method?

The earth absorbs almost 50% of the sun's solar energy and stores it below the surface. The ground loop powering a geothermal system uses that renewable energy to heat and cool homes. Traditional forms of heating and cooling like natural gas, propane, oil, air source, etc. do not use a renewable energy to operate, so they can never be as environmentally friendly. 

Traditional HVAC systems that use fossil fuels cannot be as efficient as a geothermal system because they require combustion (flames) to operate and provide heat. Air-source and ductless systems are also not as efficient as geothermal because they are creating warm or cold air based on the outdoor temperatures, which can fall well below freezing or on the opposite end, get very hot. Geothermal is transferring heat from the moderate temperatures below ground as opposed to the varying conditions we feel outside.

Compare Geothermal To Other Heating And Cooling Methods

Will Geothermal Work On My Small Lot?

Yes! This is where the different types of ground loops come into play. As long as you have a 10x10 area of land, you can do a vertical loop. 

Where Can I Install Geothermal?

Anywhere! Literally. Geothermal systems can be installed in the city, suburbs, or rural areas; anywhere between the mountains and the Caribbean; in old homes and buildings or new; and in small or large structures. We've even seen geothermal used frequently to regulate greenhouses. There's almost no job geothermal can't do.

Can I Install or Service My Geothermal System Myself?
We want you to have the highest quality experience with your GeoComfort geothermal system. Because of the importance of proper installation and service, Enertech does not sell any equipment or parts directly to homeowners. Federal, state, and local codes and regulations apply to various aspects of installation, and improperly installed or serviced equipment can lead to unit failure and health/safety concerns. For your safety and to ensure quality installations and services as best as we can, only licensed HVAC contractors should install, diagnose, or service a GeoComfort Geothermal System. We are always happy to assist your installer with tech support and purchasing equipment and parts.
What Does Geothermal Do?

Geothermal heating and cooling systems, also known as ground source heat pumps, heat, cool, and provide environmentally-friendly, energy-efficient heating, cooling, and hot water for homes and buildings.
