The specialist for starting the boiler arrived 1.5 hours after the call. I explained everything as clearly as possible and in detail. Thanks for the work.
I called an installer from this organization for the first start of the boiler. He saw that it was necessary to understand the connection of automation and began to tell me for a long time and persistently about the wrong scheme, etc. I just didn't want to connect someone else's boiler and said a bunch of unnecessary text for half an hour. He behaved extremely unprofessionally in my opinion. There was only one impression left - the main thing was to take the lunch as soon as possible and that was it.
They hung a gas boiler, strapping plus one battery, all their material, taps, tubes, plus a battery. According to the plan, the boiler turned out to be above the washbasin, which is not very convenient, so the washbasin was shifted, everything was done beautifully and according to the standard, in any case, when the gas was turned on, no problems arose. The price is moderate, everything works, we are satisfied. There are no smudges or irregularities.
