Any recommendation to reduce the frequency of defrosts? I understand that these temps favour a lot defrosting (high humidity and temps 0-3C)

Thats a lot of defrosts although in fairness my Vaillant gets up to one per hour at times

I don't know what you can do, if there are plants or anything else causing humidity near by the move them, check that the airflow is unobstructed, thats about it sofaik.  Others may be able to help.  Do you live somewhere damp even for the UK?


4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
