If you want to establish a heating system in a private house and choose the ratio of quality and price, then I recommend you cast-iron batteries. In your opinion, cast-iron radiators are something old, ugly and rusty, as well as brown, something that does not fit into the interior ?! Nothing of the kind, choosing cast-iron radiators, you guarantee yourself a warm and comfortable atmosphere at home. Cast-iron radiators are time-tested radiators, and that stereotype appeared from the fact that they have not been changed for about forty years.
In fact, now they sell a lot of beautiful cast-iron radiators, especially a lot of them in white. Such radiators look great wherever they are.
A distinctive property of cast iron is its resistance to corrosion. Cast iron as an excellent inhibitor, it seems to slow down the oxidation reaction. But in fact, this alloy of iron with carbon is very resistant to oxidation, and after 25 years you can flush the system and your radiators will last you as many years.
In general, my vote is for cast-iron radiators.
pros
cheaper and warmer, forget about heating for about 25 years.
Minuses
heavy, but install only once)
