Why Choosing the Correct Size Radiator Matters

  1. Efficiency and Comfort:

    • A radiator that is too small won’t effectively heat a room, leaving it chilly and uncomfortable.

    • Conversely, an oversized radiator will waste energy and money by overheating the room.

    • Properly sized radiators ensure optimal comfort and energy efficiency.

    Factors to Consider:

    • Room Size: The most critical factor. Larger rooms require more heat output.

    • Windows: More windows mean more heat loss. Consider their size and insulation.

    • Insulation: Well-insulated rooms retain heat better.

    • Ceiling Height: Taller rooms need higher BTU (British Thermal Unit) output.

    • Room Function: Living rooms, kitchens, bathrooms, and bedrooms have different requirements.

    Calculating BTU Requirement:

    • Measure the room’s dimensions (length, width, height).

    • Use an online BTU calculator (such as those found on DIY Doctor or Heat Adviser) to determine the required heat output.

    • Most standard size rooms need between 2000 and 6000 BTUs

    Common Radiator Sizes:

    • Heights: 300mm, 400mm, 600mm, 700mm

    • Widths: 400mm, 500mm, 2400mm

    • Choose based on room volume and BTU requirement.

    Example Calculation:

    • Room volume: 75 cubic meters (5m x 5m x 3m).

    • Rule of thumb: Use 15 cubic meters for every 1kW.

    • Room needs a 5kW output radiator (75 / 15 = 5).
