Heat pumps are energy-efficient alternatives to furnaces and central air conditioners, and one type of heat pump that is growing in popularity is the geothermal heat pump. Unlike air-source heat pumps that pull heat or coolness from the air, geothermal systems pull heat and coolness from the ground. If you are considering a geothermal heat pump, check out these important facts.
They Are Long-Lasting
Heat pumps are expensive in general, but if you choose to go with a geothermal heat pump, expect to pay a lot more than an air-source heat pump. On average and depending on various factors (soil condition, size, etc.) you may pay between $10,000 and $30,000 for your geothermal system. The advantage, however, is that geothermal heat pumps last a long time. A common misconception is that geothermal systems break down easily, but that couldn’t be further from the truth. Some parts of the system can last for decades before major maintenance is needed. Other parts require periodic maintenance to keep the system working.
They Have Low Operational Costs
Another benefit that makes the high installation cost worth it is the low operational cost. Geothermal heat pumps are even more efficient than air-source systems. If you have a system that is less than 100 percent efficient, it means you’re using more energy than the system is putting out, so you’re wasting money, but geothermal heat pumps have efficiency ratings of 300 to 600 percent. Plus, they are a lot more effective than air-source heat pumps.
They Are a Green Alternative
Geothermal heat pumps are also an extremely environmentally friendly way to heat and cool your home, and it isn’t just because they are extremely efficient at heating and cooling. Unlike some other heating and cooling options, geothermal systems use no fossil fuels, and they emit no greenhouse gasses that can damage the environment. These same benefits also make them extremely safe. You don’t have to worry about combustion, hazardous fumes or carbon monoxide.
They May Also Provide Hot Water
As an added bonus, if you get a geothermal heat pump, you may be able to use it for some of your hot water needs, too. It does this by capturing reclaimed heat that isn’t needed. This heat is then used to heat water, which can help reduce your monthly hot water heating costs. Not all geothermal heat pumps can do this, however. You’ll need one that has a desuperheater, which can use superheated gas to heat water. You’ll still need a water tank, but instead of using electricity to heat the water, you’ll use the gas from the heat pump.
Geothermal heat pumps are an extremely efficient and effective way to heat and cool your home. The upfront costs can be a little overwhelming, but when you consider the long life of the system and the monthly savings, they are well worth the cost. If you are ready to make the switch, contact a heat pump contractor in your area and request more information or a quote.
