We’re still chugging along with this blog series. Geothermal, what is it, how does it work, is it an option for you? All good questions, keep reading to find out!
Geothermal heating works by using the constant temperature of the earth as the exchange medium instead of the outside air temperature. Basically, what this means is that the temperature in the ground is steady and the opposite of what is outside, therefore if is a very good medium to use to regulate the temperature in your home. Cold outside? Warm in the ground. Hot outside? Cool in the ground. Geothermal takes advantage of this natural occurrence.
There are many variations of geothermal installations. First, let’s take a look at closed loop. Closed loop works by circulating antifreeze through a closed loop, typically a plasticor copper tubing. There are different variations in the install of the closed loop:
- Horizontal: Great for residential and new construction
- Vertical: Ideal for commercial buildings and schools
- Pond/Lake: Lowest cost option if near a body of water (also the featured image)
And then there’s the open loop option, which works by using a well or body of water as heat exchanger. It’s really only an ideal option when there is an adequate supply of clean water.
Advantages Geothermal Heating
- Cost effective
- 80% cheaper than fossil fuel powered options
- Lower utility bills
- Environmentally friendly
- United States Environmental Protection Agency has deemed geothermal as the most environmentally-safe, cost effective heating and cooling system on the market
- Even heat distribution
- Doesn’t create hot and cold blasts that can come from conventional heating and cooling systems
Brief, concise, but hopefully informative. We know shoppers out there really like to do their research before making any buying decisions, so we wanted to help with that learning process. Our last blog post will be about heat pumps and air handlers, keep up to date on their release by following us on Twitter and liking our page on Facebook.
