How To Calculate Radiator Sizes

In the UK, radiator sizes are measured in the metric system, requiring measurements in meters (m) or millimetres (mm). To accurately calculate the British Thermal Unit (BTU) output for a room, follow these steps:

  • Measure room height, width, and length.
  • Determine the size of the window area (length x width of the window in m²).
  • Use our BTU calculator for a quick and efficient calculation.

Understanding the impact of window dimensions is crucial, especially considering the heat loss potential. Single-glazed windows, for instance, demand higher BTU to counteract heat loss.

At Stelrad, we offer the UK’s largest range of radiator sizes, ensuring our calculator assists you in making the right choice. Whether opting for standard-size radiators or exploring our range of designer radiators, we help you strike the ideal balance between style, heat output, and size for efficient heating.

For those with limited space, our compact radiators present an ideal solution, tailored to smaller rooms and spaces.
