What’s the best place to put a radiator in a room?

Traditionally, the best place to put a radiator in a room was beneath the window. This is because cold drafts coming from the window would push the hot air from your radiator into the middle of the room.

However, most homes nowadays have double glazing. So, modern homeowners will have the freedom to put their radiator in any spot they choose! That said, there are still some factors you should bear in mind when you’re considering where to put your radiator.

Radiator positioning advice

Follow these general rules to get the most from your radiator both stylistically and in terms of heat output.


  • Put it behind large pieces of furniture. This can inhibit the flow of hot air around your room.
  • Place it behind curtains. Full-length curtains can swamp your radiator and trap hot air.
  • Feel bound by the existing pipework. You don’t have to put a new radiator in the same place as your old one – instead, moving it could free up valuable floor and wall space. Read our guide on the cost of moving a radiator for more information.
  • Place it behind a door (if you can help it). This could allow the hot air to flow out into the room next door, especially if it’s colder. Your radiator could also get scratched or dented if there isn’t enough space for the door to open fully.
  • Put it on an external wall (if possible). This might lead to heat escaping your home,


  • Add multiple radiators to a bigger room. As a general rule of thumb, you should aim to have one radiator for around every 4m in a room.
  • Insulate it. If you have to place your radiator on an external wall, placing foil down the back will prevent heat from escaping and reflect it back into the room.
  • Consider what you want to put on your walls. Try to put your radiators on walls that can’t be used for things like storage and furniture, so that you don’t take up valuable floor and wall space.
  • Place it in the coldest part of the room (if there is one). This can cause more effective heat conduction.
  • Think about the aesthetics. Placing your radiator in a tucked-away corner might allow it to go unnoticed Alternatively, you might choose to put a statement radiator in a highly-visible location, to enhance the look of your room.

Best place for a radiator in a bedroom

Wondering where you should place a radiator in your bedroom? It’s worth paying extra attention to where your radiator is in relation to your bed.

Not only can your bed inhibit the flow of hot air around your bedroom, but if the two are too close, you could roll over and burn yourself in the night. Sleeping too close to a radiator can also lead to overheating, headaches and insomnia.

If you’re installing a radiator in a baby’s bedroom, it’s even more important to keep their cot away from radiators. A child’s skin is four times thinner than an adult’s, so it’s more susceptible to serious burns. Babies are also at a greater risk of overheating, which is dangerous for them.

If your child’s cot has to go next to a radiator, make sure that you turn the radiator off when they’re in it so they’re not sleeping next to a heat source.
