Our Boiler Size Calculator helps you determine the precise heating capacity (BTU) needed for your space. Prevent energy waste and ensure optimal comfort by accurately sizing your boiler for residential or commercial applications. Get quick, reliable results now!
Formula:
Boiler Size (BTU/hr) = [Heated Area (sq ft) × Base BTU/sq ft Factor] + [Number of Occupants × Domestic Hot Water BTU Factor]
Where:
Heated Area (sq ft): The total square footage of the space to be heated.
Base BTU/sq ft Factor: An estimated BTU requirement per square foot, influenced by climate and insulation levels.
Number of Occupants: The number of people requiring domestic hot water from the boiler.
Domestic Hot Water BTU Factor: Additional BTU capacity allocated for hot water usage (e.g., 10,000 BTU per person).
