Geothermal & Air-Source Heat Pumps
When you are looking for an energy efficient heating system, heat pumps are one solution. There are important differences between geothermal and air source heat pumps however, and these differences might factor in your final decision. Here is a breakdown of things to consider.
Method of Operation
Air source heat pumps heat a Overland Park home in winter by gathering heat from the air outside and moving it into the home.
This might sound odd, but there is science behind it and it works based on the fact that warm temperatures always move towards cooler temperatures.
Simply put, super-cooled refrigerant collects the heat from the air like a magnet. Unlike fuel-burning heating systems, heat pumps do not create heat; instead, they simply move it. That is one big reason that heat pumps are more energy efficient.
Geothermal heat pumps work in a similar way, only the system is underground and the heat is transferred from the subsoil.
Geothermal heat pumps are more energy efficient than air source pumps. Ground temperatures are warmer and remain far more stable than air temperatures in winter, which means that geothermal heat pumps do not have to expend as much energy gathering heat. This is one reason that the government sometimes offers tax credits if you install a geothermal heat pump.
When properly installed, geothermal heat pumps usually last many years longer than air source pumps because they are not exposed to the elements. In addition, geothermal systems can often continue heating even after the temperature outdoors has gotten too cold for air source models.
If you live in a region with colder winters, this is worth careful consideration unless you already have supplemental heating to switch to when an air source pump is not heating sufficiently.
Choosing between an air source heat pump versus a geothermal heat pump is not always an easy decision. Air source units are cheaper to install and do not require excavation of the landscape, while geothermal units offer long-term savings as far as energy use and usually require fewer repairs.
To help your decision, factor in how long you plan to retain ownership of your Overland Park current home. If you intend to be there for the rest of your life, a geothermal heat pump might be the best option because of the continued energy savings.
