We have just had a power cut and 1 hour later power was restored. The heat pump powered up again and after 30 minutes I became nervous that the evaporator was at -20C, hardly any air flow across the evaporator, so I have shut it down for the rest of the evening.
How do you deal with the above situation and a iced up evaporator?
What would of happened if I had let it run in this iced up situation?
Did I do the right thing by turning off, or should I have let it run?
Thank you for your feedback.
BTW, R32 refrigerant.
