What Are Electric Radiators?
Electric radiators are modern, self-contained heating units that are becoming increasingly popular in the UK as an alternative or supplement to traditional gas central heating. They’re essentially standalone appliances that can be wall-mounted or freestanding and require only an electrical connection to operate.
How Do Electric Radiators Work?
The working principle of an electric radiator is based on converting electrical energy into heat with almost 100% efficiency. Here's a more detailed breakdown:
Heating Element: Inside the radiator, there's a heating element, which is typically a resistive wire. When electricity flows through this element, it meets resistance, causing it to heat up. This is a process known as Joule heating.
Heat Transfer: The heat generated by the element is then transferred to the body of the radiator. There are two main types of electric radiators based on how the heat is contained:
Dry Thermal Element Radiators: These use a solid material like ceramic or clay as a core. The heating element is embedded within this core, which heats up quickly and then releases warmth.
Thermal Fluid Radiators (Oil-filled): These radiators are filled with a thermal fluid, often oil. The heating element heats this fluid, which then circulates throughout the radiator body, transferring warmth to the outer surface.
