Where should a radiator be located for optimal heat distribution?

The optimal location for a radiator to achieve effective heat distribution is typically under a window along an outside wall. This placement serves a practical purpose: it helps to counteract cold drafts that may come in through the window. When the radiator heats the air near the window, it creates a convection current that circulates warm air throughout the room, thus enhancing the overall heating efficiency.

Heating systems are designed to create a balance between warmth and cold air infiltration. By placing a radiator under a window, the heat emitted rises and mixes with any cooler air that may enter, preventing cold spots and allowing for more uniform temperature throughout the space. This setup is also advantageous because it uses the natural properties of heated air—hot air rises—helping to distribute warmth effectively around the room.

In contrast, placing a radiator in locations that don’t interact with cold air, such as further away from windows or doors, may result in less effective heat circulation, leaving certain areas of a room cooler than desired.
