In the majority of UK homes, it’s common to find radiators situated beneath windows. This might initially seem counterproductive, but there’s a good reason for this placement.
During the Victorian era, many homes lacked double glazing, resulting in most heat escaping through the windows. As a result, heaters were installed under windows to retain warmth.
Today, despite improvements in insulation and the prevalence of double or triple glazing, radiators remain under windows due to thermodynamics. Hot air rises while cold air falls, a principle we learn at school.
Thus, as warm air ascends from the radiator, the cool air entering through the window pushes against it, circulating it more efficiently around the room. In addition, placing radiators under windows is not only an efficient way to heat a home, but it also makes sense from a furnishing perspective.

The space under a window is seldom used for furniture as people like to stand and look out. Therefore, installing heaters here keeps them out of the way and less noticeable than if they were in the middle of a wall.
Despite modern homes being far less draughty than those in the Victorian era, positioning radiators beneath windows remains an effective method for ensuring even heating and easier room furnishing.
When considering the installation of new radiators, it is advised to position them in areas where they won’t be obstructed by furniture. Placing a sofa in front of a radiator can result in the heat being absorbed by the furniture, preventing it from circulating around the room.
Therefore, it’s optimal to locate them in unobstructed areas.
