For the author of the only negative review (satisfied customers rarely leave reviews, only offended ones) Unfortunately, if you haven't noticed, we live in difficult conditions, all the masters are men and most of them are called up. We leave only for warranty cases, there is no physical possibility to service all boilers. It's strange that you need to explain this.
I strongly do not recommend this store. The owner flatly refused to service the boiler purchased from him. He referred to the lack of time, although I offered repairs at ANY time convenient for him during the summer.
