Radiator Calculator
Calculate the right radiator size for your room. Understand how room dimensions, insulation, and climate affect heating requirements.
Step 1: Room Details
Understanding Radiator Sizing
Proper radiator sizing ensures efficient heating. Undersized radiators won’t heat your room effectively, while oversized ones waste energy. The calculation considers room volume, insulation, and desired temperature.
Step 2: Additional Factors
About Insulation Factors
Insulation level affects how much heat is needed. Well-insulated rooms (1.0-1.2) require less heating power, while poorly insulated spaces (1.3-1.5) need more. Modern homes typically have values around 1.0.

Heat Requirement Analysis
Radiator Calculation Formula
BTU/h = Volume × ΔT × Insulation Factor × 0.133
The radiator output is calculated using a standard formula that considers room volume, temperature difference, and insulation quality. Actual requirements may vary based on window quality, external walls, and specific room characteristics.
