Do you need backup heat with geothermal?

• <div><p>If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a <a href="https://www.angi.com/articles/furnace-and-heating-basics.htm">furnace</a> or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.</p></div>

Heating Oil questions, answered by experts

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
