A domestic air-to-water heat pump has a life expectancy between ten to twenty years. But it requires regular maintenance to ensure your system is working as efficiently as possible. We would recommend having an annual check on your system by a professional – just as you would for a gas boiler.
It’s very important to have your heat pump system designed and installed by a trained professional who understands how to size and set up your heat pump system. It is a good idea to speak to them about long-term servicing requirements.
In general, if you have an air-to-water heat pump it’s a good idea to check the outdoor unit once a month to make sure no leaves or debris have collected near the air inlet. Keeping things tidy will help the unit operate effectively over the long-term.
