Is a oil heater cheap to run on electricity?

Answer 1

I think you mean "than"? Generally thought to be true, but quite often the comparison is flawed because it doesn't take account of the costs of the wastes from burning oil - smoke, and a large quantity of water vapor which can cause damaging condensation, and loss of heat due to the fact that proper ventilation has to be provided to get rid of other wastes (carbon monoxide, carbon dioxide).

Answer 2

Oil heaters can be more expensive to run on electricity compared to other types of heaters, such as electric heaters or heat pumps. Oil heaters are generally less energy efficient and can use more electricity to produce heat. It's important to consider both the initial cost and the ongoing running costs when choosing a heater for your home.
