I’ve got one which I use in the room which doesn’t have a radiator. It’s a small room, so it’s good for that, but I wouldn’t use it instead of a radiator in one of the bigger rooms in the house. When I first moved in up here, there was no working boiler so I used the oil radiator a lot for a few weeks - it was in the spring, so it wasn’t too bad, but looking at my electric bill for that time, it was quite expensive,
