Natural Gas Boiler - an overview | ScienceDirect Topics

A hot-water radiator heating system is a type of central heating. In this system, heat is generated in a boiler. For the generation of the heat, a natural gas boiler is used where the chemical energy of natural gas is transferred into the heat. Then, the heat is distributed by hot water (heat carrier) to the radiators. The radiators heat the rooms.
