1. What is Boiler Size Calculation?

Boiler size calculation determines the appropriate heating capacity needed for a house based on square footage and climate factors. Proper sizing ensures efficient heating without energy waste.

2. How Does the Calculator Work?

The calculator uses the boiler size formula:

Where:

• \( BTU \) — British Thermal Units per hour (BTU/h)
• \( Sq Ft \) — Total square footage of the house
• \( 30-50 \) — BTU factor based on climate conditions

Explanation: The formula provides a basic estimate of heating requirements, with higher factors for colder climates and lower factors for milder areas.

3. Importance of Proper Boiler Sizing

Details: Correct boiler sizing is essential for energy efficiency, comfort, and system longevity. Oversized boilers cycle frequently, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter total square footage of your house and select the appropriate BTU factor based on your local climate. For accurate results, measure all heated areas.

5. Frequently Asked Questions (FAQ)

Q1: What BTU factor should I choose?
A: Use 30 for mild climates, 40 for moderate climates, and 50 for cold climates with harsh winters.

Q2: Is this calculation accurate for all house types?
A: This provides a basic estimate. Factors like insulation, window quality, ceiling height, and house layout affect actual requirements.

Q3: Should I consider other factors besides square footage?
A: Yes, consider insulation quality, number of windows, ceiling height, and local climate conditions for precise sizing.

Q4: What if my house has multiple floors?
A: Calculate total square footage of all heated floors. Multi-story homes may require adjustments for heat distribution.

Q5: When should I consult a professional?
A: Always consult with a qualified HVAC professional for final boiler selection and installation to ensure proper sizing and compliance with local codes.
