34 Electric and Fossil Fuel Hot Water Radiator with Natural Gas Boiler This system is very common in European residential and commercial buildings that do not require air conditioning. Fresh air and cooling needs are met via operable windows. Hydronic radiators circulate hot water provided by a natural gas boiler in the basement. Circulation through the radiators is usually controlled via local valves, allowing for manual, room-by-room heating control. Flue gases are exhausted through the roof.
