The apartment is already a bit old, has long been trying to make a normal repair, when the time is right, I decided to change the radiators, the choice fell on the company STI, the batteries decided to install bimetal. They really pleased me, they have a completely collector made of steel. Vertical tubes have a wall thickness of about 1.8 mm, a bore diameter of 16 mm. The core is 100% made of steel (fully bimetal). The guarantee of such pleasure for 15 years, I think this is an acceptable period, in general lately I have been observing that more and more acquaintances are inclined to buy this brand.
After the establishment, they had already slept with them for one year, I want to say that it has become much warmer, outwardly they look good, modern. They completely cope with their main task, and what else can be desired and expected from them.
