Uses clean, renewable energy (the sun). Geothermal heating and cooling uses pipes buried underneath the ground to take advantage of the constant 55 degree temperature. However, the outdoor unit struggles to absorb heat from the air if dust, leaves/grass or a fence block airflow over the unit’s refrigerant-filled coils. Even with proper geothermal heat pump maintenance, though, sometimes things go wrong. These financial incentives further reduce geothermal’s upfront cost while operational cost remains the same. A ground source heat pump is NOT an air-to-air heat pump. 2) Covered in snow or ice Again, the heat pump needs to absorb heat from the outdoor air. We chose geothermal because of the reduced carbon footprint and the long term energy savings. The cost of geothermal systems is falling, but they’re still more expensive to install than traditional heating and cooling systems. Fact 3: Geothermal has Real Benefits Much lower operating costs than other systems. Intermediate scale geothermal systems tap into rock at temperatures from 80 to 150 degrees Celsius. That’s why your basement feels about 10 degrees cooler in the summertime than the rest of your house. In fact, millions of GHP systems are already heating and cooling homes and businesses worldwide, and that includes all 50 U.S. states. This is not hot enough for direct electrical energy generation, but it is hot enough to use heat directly for district heating (as in the city of Munich) or to run a heat exchanger to produce cold air. Once you get a few feet underground, the earth is a constant temperature of around 55 degrees Fahrenheit. A geothermal heat pump will immediately save you 30 to 60 percent on your heating and 20 to 50 percent on your cooling costs over conventional heating and cooling systems.. The myth that geothermal heat pumps do not work in cases of extreme cold is often derived from the fact that standard air source heat pumps do perform poorly in below freezing temperatures. This means, however, that they don't "catch up" as fast as fossil fuel furnaces. High Upfront Costs. One of the biggest drawbacks that puts many homeowners off switching to a geothermal heat pump is the high initial cost of installing one. A geothermal heat pump is one of the most trouble-free ways to stay cozy through Northern Michigan's snowy winters and keep cool on the warmest summer days. Geothermal heat pumps are extremely efficient when sized correctly. The geothermal ststem has 3 zones- the living room is one zone, the kitche, dining and den the second zone, and the basement and bedrooms the third zone. It cooled well in the fall but our troubles began when the heat went on in late November. The fix? What’s more, not every site is ideal for geothermal. This isn't a problem for normal heating or cooling of a home, since we want to live in a pretty steady temperature anyway, but it does mean setting the thermostat back to save money won't work. How It Works Geothermal heat pumps can operate in any climate—hot or cold—because of the earth’s constant underground temperature (from 45° to 75° F depending on location). Geothermal does not burn fossil fuels to heat and cool buildings, so renewable energy programs often use financial incentives to further encourage homeowners to upgrade and go green. When that happens, a little troubleshooting can help you get your system running again. Clean the outside unit and ensure that you’re not surrounding it with a fence or cover. Geothermal heat pump users should be aware that in the absence of using renewable generated electricity to drive the heating/cooling process (e.g., modes) that geothermal heat pump systems may not be fully fossil-fuel free (e.g., renewable-based).
