Serving Springfield and Surrounding Areas
One of the biggest questions we get is about Geothermal heating and cooling, benefits, costs and just exactly how does it work? Let’s answer the last question first.
To a large extent it works like your own refrigerator. Your fridge removes heat from its interior and transfers it to your kitchen. A geothermal heat pump uses the same principle, but it transfers heat from the ground to your house (or vice versa). It does this through long loops of underground pipes filled with liquid (water or an antifreeze solution). The loops are hooked up to a geothermal heat pump in your home, which acts as both a furnace and an air conditioner.
During the heating season, the liquid pulls heat from the ground and delivers it to the geothermal unit and then to refrigerant coils, where the heat is distributed through a forced-air or hydronic system. During the cooling season, the process runs in reverse. The pump removes heat from your house and transfers it to the earth. Many units can provide domestic hot water as well.
A geothermal heat pump is vastly more efficient than conventional heating systems because it doesn’t burn fuel to create warmth; it simply moves existing heat from one place to another. And because temperatures underground remain a relatively constant 50 degrees F year round, the system requires a lot less energy to cool your home than conventional AC systems or air-source heat pumps, which use outside air as a transfer medium.
Now let’s look at benefits.
Much lower operating costs than other systems. 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.
Uses clean, renewable energy (the sun). With a geothermal heat pump, there’s no onsite combustion and therefore no emissions of carbon dioxide, carbon monoxide or other greenhouse gases. Nor are there any combustion-related safety or air quality issues inside the house. (However, the pump unit uses electricity, which may be generated using fossil fuels.)
Much quieter than other cooling systems. There’s no noisy outdoor compressor or fan. The indoor unit is generally as loud as a refrigerator.
Low maintenance and long-lived. The indoor components typically last about 25 years (compared with 15 years or less for a furnace or conventional AC unit) and more than 50 years for the ground loop. The system has fewer moving parts and is protected from outdoor elements, so it requires minimal maintenance.
Thirdly, let’s discuss cost. This can really only be done after looking at your individual home and needs. If you feel like a Geothermal heating and cool system is the best option for you, give us a call to schedule a free estimate and consultation.
