This is the source of fuel your radiator or towel rail will use to provide heat. Radiators will generate heat through central heating systems, electricity, or a combination of both with dual fuel.
Central Heating:
These radiators will generate heat through the water pumped round your central heating system.
Electric:
Electric radiators contain fluid heated by an electrical element. They plug into a socket or are wired directly into the mains.
Dual Fuel:
Dual fuel radiators are able to run on both central heating and electric power. They contain a ‘summer’ heating element which will allow you to use your radiator in warmer months without needing to turn on your entire central heating system.
