The main difference between a ground source heat pump and a traditional air conditioner is that the former operates on warmer ground temperatures and, therefore, is more efficient in colder climates. Ground source heat pumps, with their high COP (Coefficient of Performance) of three, can cut your heating and cooling bills by up to 65%. Regardless of the type of ground source heat pump that you choose for your home, it’s important to choose the right size ground loop.
A ground source heat pump is a natural heat exchanger that utilizes the constant temperature of the earth as its heat source. The heat transferred to your home through the ground source is concentrated and used for space heating, hot water production, or both. Heat from the ground can also be used to heat ductwork and transfer air throughout your home. This type of system is very efficient because it doesn’t require a compressor or a high-tech air conditioner. air source heat pump
Heat pumps can provide warmth in both winter and summer. The heat produced by a ground source heat pump is measured in British thermal units per hour (Btu/h), which is equivalent to the heat generated by a birthday candle. Heat pump capacity is measured in tons. A ton is equal to 3.5 kW or 12 000 Btu/h. In general, a ton is the highest capacity. A ton of heat exchangers can provide up to 12% of a home’s heating needs.
Typically, a GSHP system can provide 100% of a home’s heating and cooling needs, though it is often smaller and installed with auxiliary heat sources for additional flexibility. Closed-loop systems rely on ground loops of PVC or polyethylene piping that circulate water or antifreeze. A horizontal loop can be a few feet deep. The system itself can be submerged in water or be connected to an indoor heat pump.
The upfront cost of installing a ground-source heat pump is higher than installing an air-source system, but the money you save can be easily recovered in five to ten years’ time through energy savings. Moreover, a ground-source heat pump can last up to 75 years if it’s run with clean electricity. In addition to its many advantages, a ground-source heat pump is eco-friendly, and is one of the most cost-efficient heating and cooling systems available.
Another benefit of installing a ground source heat pump is the reduced cost of fossil fuels. Although you will spend more money initially on installation, it may also reduce your energy bills significantly. Even more, a heat pump saves the environment by reducing carbon emissions, which is a major source of pollution. If you’re unsure about whether or not a ground-source heat pump is right for your home, consider consulting an energy advisor or contractor.
A ground-source heat pump can be installed in any climate. The geothermal system can be installed almost anywhere in the United States, as long as the ground temperature is 50 degrees Fahrenheit or warmer. There are two types of ground source heat pumps: vertical and horizontal systems, with different levels of efficiency and savings. Depending on where you live, you can choose a closed-loop system, or an open-loop system that uses a pond or lake. In open-loop systems, you can connect a well or a standing column.
