The Hidden Cost of Getting Radiators Wrong

(Why Settling for "Cheap" Costs You More)

Mistake

Consequence

Smart Fix

Undersized radiators

Rooms never reach the desired temperature

BTU-calculated sizing

Low-quality materials

Corrosion leaks in 3-5 years

Stainless steel/aluminium

Wrong type for the room

Cold spots + 30% higher bills

Room-specific designs

Poor valve pairing

Inefficient heat control

Thermostatic radiator valves

Trade Insight: "Many homeowners replace boilers when radiators are the real issue. Proper sizing and material choice impact efficiency more than your heat source."

The 4-Step Radiator Sizing Formula (No Maths Degree Required!)

Avoid costly miscalculations with this trade-approved method:

  1. Calculate Room Volume
    Length (m) × Width (m) × Height (m) = m³

  2. Multiply by BTU Factor

    • Standard room: × 70

    • North-facing/old build: × 90

    • Modern insulation: × 50

  3. Add Extras
    +10% per window, +20% for exterior walls

  4. Match to Radiator Output
    Example:
    5m × 4m × 2.4m = 48m³
    48 × 70 = 3,360 BTU
    +20% (exterior wall) = 4,032 BTU
    → Choose radiator with ≥4,000 BTU output
