Despite some common geothermal myths, a geothermal heat pump is likely to be a good choice for heating and cooling your Cleveland area home. Any type of heat pump has high energy efficiency because it uses a relatively small amount of electricity to move heat from one place to another, rather than burning fossil fuels to generate heat.
A geothermal, or ground-source, heat pump extracts heat from the ground several feet below the surface, where the year-round temperature stays relatively constant, and then moves the heat into your home on cold days. The system reverses to provide indoor cooling on hot days. There are some common misunderstandings about geothermal heat pumps that might discourage you from choosing this energy-efficient solution for your home. Here are some common geothermal myths and simple explanations to debunk them:
- Myth: Geothermal home HVAC systems run on steam from deep underground. While large-scale power plants in unique geological areas use super-heated steam from deep wells to generate electricity, home geothermal systems use a simple ground loop buried beneath the frost line in your yard as a source of heat energy for heating and cooling your home.
- Myth: Geothermal systems put toxic refrigerants into the ground. Most modern systems use water rather than refrigerant in their ground loops. The water may be mixed with a small amount of anti-freeze.
- Myth: Geothermal systems waste water. Most modern geothermal systems used a closed loop filled with water that never leaves the system. Even open loop systems that take water from an aquifer return the water to the aquifer after heat is extracted from it.
- Myth: Geothermal heat pumps are not as cost effective as wind and solar systems. Home geothermal systems are far more cost-effective than wind or solar systems in removing home heating and cooling loads from the electrical grid.
- Myth: You need a huge yard for a geothermal heat pump. A ground-source heat pump loop does not require much yard space if it’s excavated and installed vertically.
