Where should a radiator be installed in a room?

The best installation location for a radiator is on an exterior wall below a window. This is because placing the radiator in this position helps effectively counteract the cold air that enters the room through the window. Radiators provide heat that rises, and installing them below windows allows the warm air to circulate and mix with the cooler air coming from outdoors, creating a more even temperature throughout the room.

Additionally, this setup helps prevent condensation on windows, which can occur when there is a significant temperature difference between the inside and outside. By ensuring that the heat is directed toward the window area, you can minimize drafts and create a comfortable living environment.

In contrast, installing a radiator on an interior wall may not provide efficient heating, as it does not address the draft from the exterior walls and windows. Positioning a radiator on the ceiling is generally impractical and ineffective due to heat rising and not promoting proper air circulation. Finally, while placing it on an exterior wall is beneficial, doing so without positioning it below a window misses the opportunity to combat cold drafts entering through the window effectively, making it less ideal than the recommended placement.
