Heat pumps work by taking heat located outside of your home and transferring that heat into your home. Heat pumps come in two main variants: air source heat pumps and geothermal heat pumps. Both of these types of heaters work in different manners to provide the same function to your home. Understanding the difference between these two types of heat pumps can help you choose the one that best fits your needs.
Air Source Heat Pumps
Air source heat pumps work, like their name suggests, by moving heat from the air outside of your home to the air inside of your home, and in reverse during the summer months when you want to cool your home down. They are much more efficient than traditional heating and cooling systems, and some models even work to dehumidify your home as well, which will save you money over time on your energy bills. Air source heat pumps will also save you space when compared to traditional heating and cooling systems.
However, they require moderate climates to work properly, and will not be able to heat your home in severe cold weather, as there is not enough heat outside of your home to actually raise the temperature inside. This can be a major drawback, and makes air source heat pumps less desirable to homeowners in cold climates.
Geothermal Heat Pumps
Geothermal heat pumps work by moving heat from deep in the ground into your house (and vice versa depending on the season). They will work in all sorts of climates, because they draw heat from so deep in the ground that exterior temperatures have little effect on the pool of available heat to transfer. Geothermal heat pumps are also much more energy efficient when compared to air source heat pumps, which will save you even more money over time when compared to traditional heating and cooling costs.
The main drawback of geothermal heat pumps is that they are extremely expensive to install, due to the intensive installation process, which can make them an unviable option for homeowners operating under a budget. Though the increased energy savings of geothermal heat pumps helps to offset this cost, the initial investment can still be quite steep. Additionally, geothermal installations require a certain type of soil and landscape, which means that your home may not be located in a place that is conducive to having a geothermal heat pump installed anyway.
