The advantages and disadvantages of turning off radiators in rooms we do not use

If you have rooms in the house which you rarely use, it makes sense to turn the radiators off and close the doors when you don’t need the room. In fact, there’s probably only one disadvantage in doing so, which is the problem of damp.

North-facing rooms are particularly at risk of damp, and there’s no point in trying to save money by turning the radiator off if you end up having to pay to get rid of the damp. The best thing to do is to remember to turn on the heat intermittently to prevent the room smelling fusty. Also remember to air the room from time to time.

If you have a frost setting on the radiator valve (usually a snowflake symbol), it’ll be a good idea to keep the electric radiator or its designer radiator counterpart on that setting rather than turned off completely. That way, if there’s an unexpected frost in the night, the radiator will come on just high enough to prevent your pipes freezing.


As long as you close the doors so the cold air doesn’t seep into the rest of the house, you will save money by turning off the radiators in unused rooms. By doing so, you’ll prevent the water in the system running through that particular radiator. Your boiler uses up the same amount of energy however many radiators it has to heat, but by turning some of them off, your boiler will work more efficiently, meaning the rest of the house will warm up sooner so the boiler switches off sooner, and you’ll save money because you’re using less gas.

When it’s really cold

When the weather turns really cold, many people think you should leave the heating on low all day in order to save money on your bills, but according to the Energy Saving Trust, this is a myth. They say that whenever your heating’s on, you lose a proportion of it through the walls and windows (how much depends on how well insulated your house is), so the more heat you use, the more heat you lose. Their advice is to set the time for your heating to come on a little earlier than normally to ensure your house is nice and warm before you get home. Other people dispute this theory, but as yet there doesn’t seem to be any scientific proof on either side.


Our designer radiators will keep you warm and cosy throughout even the coldest winters. Come and see them for yourself at one of our showrooms.
