Air source heat pumps are useful units when it comes to heating an enclosed space, such as homes or offices. However there are air source heat pumps disadvantages. For those who don’t know, air source hear pumps function are basically two-way air conditioners, moving heat from the cool indoors to the warmer outdoors in summer. In winter, the air source heat absorbs heat from the outside and transfers it inside using an electrical system. Another type of heat pump is the ground-source heat pump, which uses the heat underground as the heat source.
In cold climes, heating homes and work places has long been implemented through various means such as the use of fireplaces. Today, there are a range of options available, including air source heat pumps, ground-source heat pumps, furnaces, boilers, wood burning and pellet stoves, and electric heat pumps. However, in this article we focus on air source heat pumps advantages and disadvantages.
Comparison with other heating/cooling systems
Although air source heat pumps do have advantage, such as being safer than combustion-based systems, cheaper to run than oil and gas boilers, a lower carbon emitter, easier to maintain than combustion based systems, able to provide cooling in the summer, and designed to have long life spans, they also come with their own set of limitations or disadvantages. Knowledge of these disadvantages combined with information on other heating options can help you find the right fit for your heating needs.
1. Since and air source heat pump cannot use heat in the underground, its utility is reduced in the winter, when the ground outside is warmer than the air outside. Therefore it is less efficient in winter. Ground source heat pumps on the other hand are able to use this heat in the ground.
2. Air source heat pumps work well when temperatures are above freezing. Supplemental heating coils are usually used when the temperature drops below freezing. These coils use electricity as the energy source and could increase your heating bill.
3. In winter, the coils in the outdoor condenser can freeze.
4. Only highly energy efficient homes can make full use of air source heat pumps.
