What is the approximate life-cycle of a heat pump?


Heat pumps are enjoying high popularity as a method of heating the house due to a number of reasons. First of all, they are environmentally-friendly, and many people today think about the environment and, if the money is not a problem for them, they choose maybe more a but ecological solution. Second of all, they allow homeowners to save on bills, because they need a lot less electricity than other heating devices, like furnaces or boilers. That is, among others, the reason why these cost-effective, environmentally clean and efficient devices are often purchased and used in the buildings.


When someone wonders which heating device to choose, they often take a life-span of the equipment into account as an important aspect, affecting the final decision. However, this is not easy to provide information on the longevity of a heat pump, since it depends on numerous factors.


Weather has certainly big influence on the life-span of this equipment. In places where winters are longer and colder, the device has to work more because the heating season is longer, and this shortens its longevity to a certain degree. In coastal and subtropical areas, the life span is also shortened because of various chemicals coming from saltwater. Also such weather conditions as monsoon season may reduce the longevity of the device, so it is worth to protect it from such conditions.


Another important issue is the proper maintenance of heat pumps. If the device is consistently maintained and regularly serviced, it will live longer, which actually refers to most of equipment. But if we see our device needs often repairs, we may unfortunately expect that its years or even months are numbered.
Life expectancy of heat pumps also depends on the frequency of their use. If the unit is utilized often, it will wear sooner. Of course the frequency is often connected with the climate of the country, where the building and its pump are located, and also on the attitude of residents. Some people need more warmth, and they will force the pump to work harder, which will for sure decrease its life span.


How can we extend the life cycle of a heat pump?


After buying the equipment, we obviously want it to operate as long as possible. Fortunately, there are many things we can do to maximize the life-cycle of our heat pump. We should replace air filters regularly, periodically check the device during the winter to examine whether there is no snow or ice that got into the machine or builds up on top of it, because it can destroy it. We should call a professional to service and maintain our heat pump at least once a year. It is also important not to put any plants nearby the unit. The plants should not stand in the place located within the radius of 50 centimeters from the heat pump. In order to make the pump run for a longer period of time, we should also regularly check if the coils are clean, and if they are not, we should use a degreasing agent to clean them.


According to the associations of home builders operating in different countries and experts working in institutes dealing with the examination of such devices, the average and approximate life expectancy of a heat pump is about fifteen years. Of course, the manufacturers of this equipment constantly improve it, and they will certainly attempt to prolong it, but for now we can expect such a period. Even if our heat pump will run well after such time, it is still recommended to replace it after fifteen years, because it loses its properties. It often stops defrosting, which usually requires the replacement of electronic board. Another reason is that the older the device gets, the more electricity it will need, which will in consequence lead to higher utility bills. Therefore investing money in such an old device is not economical both in the short and long-term, it is better to use the money for the repair for the purchase of a new one.
