In passport data, 1.8 kW of heat is declared, in fact, about 1 kW. I bought 6 radiators, they worked for about two months, they are not worth their money. They were not accepted back from me, now they are gathering dust in the basement.
Included some photos to show the product's packaging and presentation.
