The heat pump water heater is one of the most innovative and eco-sustainable solutions for producing domestic hot water. But certain minor problems may sometimes interfere with its perfect operation: let’s find out together, with this practical mini-guide, how to promptly identify the most frequent problems and solve them.

1. It’s not producing hot water anymore

If your heat pump water heater isn’t producing enough hot water, or any at all, it may be due to several reasons: the heat exchangers, for example, may be encrusted with limescale, or the filter could be dirty. Alternatively, the valve might be closed or even locked. In these cases our tip is to contact one of our technicians and get some water heater maintenance done.

2. The electricity bill is still high

We’ve installed a heat pump water heater but the electricity bill is still higher than we expected? Immediately check the tariff applied to your energy account. Most operators offer special tariffs exclusively for heat pump owners. Our advice is therefore to shop around for the best offers that suit your needs and life style. Find out here how it’s to possible to save on average with a heat pump and see the positive impact it has on the environment.

3. The heat pump is making noises

Like all heating systems, a heat pump water heater produces vibrations and sometimes noise as well, which may be annoying, depending on the model and especially if it’s installed indoors. To solve this problem we can put the heat pump on a special pad to absorb vibrations and dampen noise. If you haven’t got a heat pump water heater yet but you are looking at the various products on the market, we would suggest choosing a model with a SILENT function, like Ariston’s NUOS PRIMO A+, for example.
