Hello, in my neighborhood, the heat pumps are now gradually failing. One reason often mentioned is the lockout periods where heat pumps basically make a full stop.
However, this mainly has to do with the fact that one or the other electricity specialist at the time "hardwired" the units, meaning: the entire system was killed with the shutdown signal.
Electronics don’t like that.
Nowadays, the system receives the signal and runs down gently, so nothing else can happen.
Otherwise, I agree with : it has to be quite a big hassle for it to be worth it...
