How to lower the cost of running an oil-filled radiator
An oil-filled radiator heats sealed-in oil, which then releases heat slowly through the fins. It is not more efficient than a fan heater — electricity to heat is still about 1:1 — but the stored heat means the thermostat switches the element off for longer stretches once the room is warm. We assume the element is on about 70% of the time, so a 1,500W radiator averages roughly 1.05 kWh per hour of use. Expect the real number to be higher in a cold, drafty room and lower in a well-insulated one.
- Set the thermostat dial to the lowest comfortable setting and let the oil do the work.
- Place it near the coldest wall or under a window, away from furniture that blocks the fins.
- Switch to the lower power setting (600–900W) once the room is up to temperature.
