Does geothermal need a boiler?

No, geothermal systems do not require a boiler. Geothermal systems use the natural heat of the earth to heat and cool a home, eliminating the need for a boiler. Instead, a geothermal system uses a series of pipes buried in the ground to transfer heat from the earth to the home. The pipes are filled with a liquid that absorbs the heat from the ground and carries it to the home. The heat is then used to heat the home and the excess heat is released back into the ground. This process is repeated in reverse to cool the home.
