Furnace BTU Calculator
Calculate the BTU (British Thermal Unit) requirements for heating your space. Compare different furnace types and sizes to find the most efficient heating solution for your needs.
Step 1: Space Details
Understanding BTU Requirements
BTU (British Thermal Unit) measures heating capacity. Larger spaces, colder climates, and poor insulation require higher BTU ratings for effective heating.
Step 2: Heating Factors
About Heating Factors
Insulation quality, window type, and climate zone significantly impact BTU requirements. Well-insulated spaces in mild climates require less heating capacity than poorly insulated spaces in cold climates.

BTU Requirement Breakdown
BTU Calculation Formula
BTU = (Volume × Temperature Difference × Climate Factor) ÷ Insulation Factor
The BTU requirement is calculated based on room volume, desired temperature increase, climate zone, and insulation quality. Additional factors like windows and doors increase the required heating capacity.
