Heat Calculator

Use our Heat Calculator to help give you an idea of the heat output you need for each room. For a more detailed estimate, please contact us directly on 01205 280354.

The figures given are based on the property having un-insulated (air gap) cavity walls, wooden floors, and a 2.4M high ceiling with a proportionate double glazed window area.

For insulated cavity walls deduct 20%, for solid walls add 10%. This basic heat loss calculator makes various assumptions based on your choices and may not take into account all factors relating to your particular requirements. If you require a more detailed calculation please contact the office to discuss your particular needs. We accept no liability for any errors resulting from the estimates given. Calculations are based on Delta-T 50°C (Δ-T50°C) in accordance with BS EN 442.
