Electric oil filled radiators retain and radiate heat even when turned off. So how energy efficient are they compared to other electric space heaters?


Are electric oil filled radiators energy efficient?

What is an electric oil filled radiator?

Electric oil-filled radiator is a type of electric heater that uses oil as a heat transfer fluid. It provides a more even distribution of heat when compared to other electric space heaters. Electric oil filled radiators are a good choice for homes or businesses that want to reduce their energy consumption and save money on heating costs.

How do electric oil filled radiators work?

Electric oil filled radiators work with a combination of of radiant and convection heating. Oil filled radiators heat a reservoir of thermal oil using a submerged electrical element inside the appliance. When the electrical heating element heats up, the heat created is transferred to the surrounding oil which then heats up the body of the radiator. This process circulates warm air around the room by convection and also radiate heat, providing consistent and efficient heating.

How much energy do electric oil-filled radiators use?

The amount of energy that an electric oil filled radiator uses depends on its size and power rating. Generally speaking, the larger the radiator and the higher the power rating, the more energy it will use. Typically, these radiators come in ratings of 1000 W, 1500 W, 2000 W or more.

Are electric oil filled radiators more efficient than other electric space heaters?

Compared to other electric space heaters - oil filled radiators are as energy efficient as almost any other space heater that uses a heating element to convert electrical energy to heat. This is because of the fact that for 1 kW of electrical energy, a heating element can produce 1 kW of heat. The main difference, however, is the fact that oil filled radiators store heat and provide a more constant temperature, while other heaters stop producing heat once they are turned off or the thermostat reached the desired temperature.
