If you are looking into having an air source heat pump installed then you’ll want to be clear on what will be involved in maintaining it.
Air source heat pumps usually go on working for a good 20 years, although you will need to arrange regular maintenance to prolong the operation. It is good practice to carry out your own checks every year, and then call in a professional every three to five years. They will check various things including levels of anti-freeze s as to prevent the pump from freezing in low temperatures.
The precise checks you need to carry out depend on the particular model, but generally you should ensure the air inlet grill and evaporator are free from debris. Leaves and the like are going to be your worst offenders. Also it is a good idea to remove any plants that have started to grow up around the pump.
It is also good practice to check the pressure gauge on your central heating periodically and your installer will show you how to do this.
Should something go wrong, generally you be able to rely on a manufacturer’s warranty of between two and three years and there will usually be an option to extend the warranty for a fixed price.
Overall air heat source pumps are straightforward to maintain and will present very few issues providing simple steps are taken to keep them clear from debris. We certainly recommend them as a viable alternative to traditional boilers.
