Pros

Cons

I recommend it only to those who love repairing and dealing with viruses

I recommend these for technical applications
Heats 9 kW of an area of 150 m2. Not great in size. Not expensive. It’s already on the 5th day
The click is already loud. The lights under the buttons light up steadily. I serviced it twice: once by dripping in the middle, once by burning out the temperature sensor. If the water boils with a low pressure in the system, and the thief does not turn on the boiler

Virib for refinishing with a file!

Leaks from every joint. The terminals are not tightened. The contactor operates so loudly that it can be heard throughout the whole house! A classic of Ukrainian assembly at its worst. I do not recommend!
No
Leaking from every joint. The terminals are not tightened. The contactor is so loud you can hear it throughout the whole house! Classic Ukrainian assembly on a knee. I do not recommend it!
good model, liked it

Would consume a bit less electricity.
It heats an even larger area than specified in the specifications.
Weak wire from the outlet to the boiler itself.
 i recommend it should buy
