What is it:
Geothermal energy is the thermal energy in the earth’s crust that originates from the planet’s formation and from the slow decay of radioactive particles in the earth’s core.
How it works:
Geothermal systems also called ground-source heat pumps, transfer heat to and from the ground for home cooling and heating respectively.
The system uses closed-loop piping and circulates fluid through it. Either horizontal trenches approximately 6′ deep or vertical wells are used to capture the energy within the earth. In the winter, as the fluid circulates through the loop, it absorbs the heat from the ground around it. The heat pump extracts the heat from the fluid as it puts it into your home.
By switching the direction of the heat flow, heat can be removed from your home and sent back into the earth keeping your house comfortable on the warmest summer days.
Like other new HVAC systems that rely on renewable energy, the upfront cost of geothermal can be high. Although, these additional costs will be returned in energy savings in 5 to 10 years (depending on the cost of energy). These systems are great for the environment and your energy bill! Additionally, geothermal is a great option for anyone looking to build a net zero home.
When it comes to environmentally friendly HVAC systems, geothermal heat pumps are a promising and increasingly popular option. Want to learn more about how geothermal is right for your home? Get in touch with us today!
