"the instructions contain the standards of the wires"
The story of how the electric boiler tecline was inserted is a good cool Chinese one
I have a gas valiant boiler at home, the same service company and a cool service specialist Pavel (it was because of the professionalism of this person that I thought the whole company was like that)
In a room of 30 sq. m, a boiler was needed to heat the floor only. After calling the managers and asking "how many kilowatts the boiler is needed", Bosch telein was named for 5 and discussing all the boilers, Bosch and the others persuaded them to take Chinese for 6 kV inside with a expansion tank with a pump, the manager said that "you will reduce its power, there are modes and you will be happy." Well, I think it's not worth contacting the Russians with boilers, separately assemble the expansion tank pump, let's put an expensive Chinese assembly with a completely warranty, like everything is there. I sent a plumber, he bought everything a 1400rub boiler and everything for underfloor heating pipe connections everything is Italy, everything is good, even a street sensor was inserted (I don't know who was supposed to mount it but it's lying in a box), in total, 3800r came out with a boiler, I don't remember with or without a plumbing discount (specification 2821 of 06/03/14 information for companies).
Everything was mounted, connected, the plumber also took money for the work (not three kopecks, of course) and forgot, handed over the object, it's time to call the service master to start the boiler and then a call from Pavel will be with you soon.
Upon arrival, seeing everything done, even sewn up, he says I will not connect it since the cable section does not allow. The cable is designed for 5 kV, the boiler is regulated by 3 power positions, i.e. 2 4 and 6 kilowatts and nothing else. That is, at 4kv, if I turn on something else, the wires will already start to warm up, at best they will knock out the machine, at worst they will float and short out and burn
With the words, why do you need a 2 kV colorizer for a huge pile of money that will not cope with heating everything, he did not undertake to connect it under his own responsibility so as not to burn out.
The bottom line is that when selling the boiler, no one clarified anything about the input cables and about the operating conditions that I need a boiler for about a maximum of 3.5 kV of power to be regulated, only the question was about power
That is, the boiler does not fit my parameters, it cannot be set as needed
Only on 2 kV and 4 which is on the verge and will knock out the machine.
There was no way to replace the cable, it lay deep in the ground and entered the shield into the house
And now, as a result, having poured in a lot of money, you need to redo or put a new cable from the meter from the vending machine on a pole (and will I have enough input power from the vending machine so that the house and boiler work without knocking out everything at once) and the cable will look crooked on the territory, because the construction is finished (fences lawns interior decoration), or throw it away a boiler and put a new one that can produce 3 ~ 3.5 kilowatts with a tank with a pump.
The boiler, of course, was not taken away as a "high-tech" product, although it was not connected, answering "the instructions contain the norms of wires."
So the "seller" could find out all this initially what, for what and how, where, what is ready, if it was reported that there is no such boiler or you need another boiler, this one will not set the parameters, or a new wiring line, we would think about it all with a plumber how to heat and put it maybe the electric underfloor heating in general would have been forgotten and a lot of money would not have gone to either the company or the plumbing for installation.
And so everyone around has earned, so also the electrician will earn after all, or the next plumber with a new boiler sales company, depending on how we decide.
The service department, namely Pavel, is very grateful
Sales Department - I don't want to be called names here
They just set up a pair of green tractors - "the instructions contain the norms of wires"
Ps I'm surprised why they advised / sold me for 6kV and not for 20kV, provided that at 5 kV maximum. they would have said the safety margin of the boiler and it would have rolled, sellers use a free life hack
A great company if you want to build a house from high-quality materials.))) many thanks to the manager Alexander. He's already helped me out many times. I recommend it!
A cool store, there is everything for the comfort of home, kind professional staff, despite the fact that the sleeping area and the place are right next to each other, they have their own convenient frame for loading, they will help, they will tell!!!!
