When selecting suitable radiators, you should consider their technical characteristics and quality of performance, giving preference only to models of proven manufacturers. All devices must comply with the conditions of the central heating, if we are talking about the apartments of multi-storey houses.I have recently just like you asked a similar question with the choice of plumber .People who live in cottages and private houses, can install any radiators, guided by the project, drawn up by an engineer, taking into account the area and cubic capacity of the living space.
