  • Different Types of Radiator/ Boiler Systems Hunker

    Next to forced-air heat, a boiler-and-radiator system is the most common type of heating system in cold-winter climates. All boiler systems use hot water to heat the home. There are two main types of boilers—steam and hot water (also known as hydronic)—and many more types of radiators or heating appliances, the units that transmit the heat into the rooms.
