Automatic operation is not possible or defective, not to say bypassed (according to the district chimney sweep, he does not have to check it and cannot do so) Definitely
It wears out more (1000 euros more electricity (600 euros!!) and energy costs per year) Eventually something will burn out... I don't find 5 years normal, the safety concerns me and my family
It's only about whether you are really allowed to operate it legally like that (5 years and more)? I am the owner with a new heating system. What if something burns out opposite? The district chimney sweep says you have to sign after inspection that you have to switch to automatic. Only he has to recognize on site that it doesn't work at all. And does nothing. But he sees no safety risk.
