Watch how the flowers grow.

It sounds really obvious, but one of the biggest differences between your air source heat pump and a traditional boiler is that your heat pump lives outside. Nobody’s ever needed to weed out vegetation from the cupboard where a boiler sits. However, it’s worth keeping an eye on the area around your air source heat pump and getting rid of any leaves, plants or branches that are getting in the way of vents or pipes. Clear away any other debris, rubbish or garden toys from the areas around it, too. The instructions that come with your heat pump will give you the details of what to look out for in order to keep it running at its best.

I often have to spend a portion of my time clearing away bushes and leaves that have grown on or too close to the unit. Also keep an eye out for certain points and trees that drop a cotton like material from them as these often get sucked into the back of the heat pump and block airflow causing in overheating of the boards which can fry them.
