4. BTU & Heat Output Guide
Choosing the right BTU (British Thermal Unit) is the most important part of buying a radiator.
4.1 What Is BTU?
BTU measures how much heat a radiator emits.
The higher the BTU, the more heat it produces.
4.2 How to Calculate BTU Requirements
Step 1 — Measure the room
Length × width × height (in metres)
Step 2 — Multiply by 153
This gives a good baseline BTU requirement.
Room Volume x 153 = Required BTU
Step 3 — Adjust for insulation
- Poor insulation: +20%
- Large windows: +10%
- North‑facing: +15%
5. Radiator Sizes Explained
Choosing the right size ensures your radiator fits the space and provides enough heat.
5.1 Height
Common heights:
- 300mm
- 600mm
- 1200mm
- 1800mm
Tall radiators are ideal for narrow walls.
5.2 Width
Wider radiators distribute heat more evenly across the room.
5.3 Projection
Projection = how far the radiator sticks out from the wall.
Important for tight spaces and walkways.
