1. What is Heat Load Calculation?

Heat load calculation determines the amount of heating required to maintain a comfortable temperature in a space. It's measured in British Thermal Units per hour (BTU/h) and considers factors like room size and type.

2. How Does the Calculator Work?

The calculator uses the heat load formula:

Where:

• \( Area \) — Room area in square feet
• \( Factor \) — BTU per square foot based on room type

Standard Factors:

• Living Room: 20 BTU/sq ft
• Bedroom: 15 BTU/sq ft
• Kitchen: 25 BTU/sq ft
• Bathroom: 10 BTU/sq ft
• Office: 18 BTU/sq ft

3. Importance of Heat Load Calculation

Details: Proper heat load calculation ensures efficient heating system sizing, prevents energy waste, and maintains comfortable indoor temperatures.

4. Using the Calculator

Tips: Measure your room's length and width to calculate area in square feet. Select the appropriate room type for accurate factor application.

5. Frequently Asked Questions (FAQ)

Q1: What if my room has high ceilings?
A: For ceilings over 8 feet, multiply the result by 1.25 for each additional foot.

Q2: How does insulation affect heat load?
A: Well-insulated rooms may require 10-20% less heating capacity, while poorly insulated rooms may need more.

Q3: Should I include windows in the calculation?
A: This simplified calculator assumes average window coverage. For many/large windows, add 10% to the result.

Q4: What about rooms with multiple exterior walls?
A: For each additional exterior wall beyond one, add 10% to the calculated heat load.

Q5: Is this suitable for whole-house calculations?
A: For whole-house calculations, sum the heat loads of all rooms and add 20% for duct losses.
