How Do Geothermal Heat Pumps Work?
Unlike traditional HVAC systems that burn fossil fuels or use electricity inefficiently, geothermal heat pumps use the Earth’s natural heat. Beneath the surface, the ground maintains a constant temperature year-round. A geothermal system transfers heat between your home and the Earth through an underground loop system filled with a heat-conducting fluid.
During winter, the pump extracts heat from the ground and moves it indoors. In summer, the process reverses, pulling heat from your home and transferring it underground, keeping your house cool.
Types of Geothermal Heat Pump Systems
There are several types of geothermal systems, each designed to fit different land and climate conditions:
- Closed-loop systems (most common)
- Horizontal loops: Installed in shallow trenches, best for homes with plenty of yard space.
- Vertical loops: Require deep boreholes, ideal for smaller properties.
- Pond/lake loops: Use a nearby water source for heat exchange.
- Open-loop systems
- Use well or pond water directly for heat exchange.
- Require a reliable and clean water source.
