1. What is a Stove Size Calculator?

Definition: This calculator determines the appropriate stove size in kilowatts based on your heating load in BTU/h.

Purpose: It helps homeowners and professionals select the correctly sized stove for efficient heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Stove power output (kilowatts)
• \( Q_{btu} \) — Heating load (BTU per hour)

Explanation: The formula converts BTU/h to kilowatts (1 kW = 3412 BTU/h) to determine the required stove size.

3. Importance of Correct Stove Sizing

Details: Proper sizing ensures efficient operation, prevents over-firing (which can damage the stove), and avoids under-firing (which leads to insufficient heating).

4. Using the Calculator

Tips: Enter your heating load in BTU/h. The calculator will output the recommended stove size in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my heating load?
A: Calculate based on room size, insulation, climate, and desired temperature increase. Professional heat loss calculations are most accurate.

Q2: What's the conversion factor 3412?
A: It's the number of BTUs per hour equivalent to 1 kilowatt (1 kW = 3412 BTU/h).

Q3: Should I round up the stove size?
A: Generally yes, but not more than 10-15% larger than calculated to maintain efficiency.

Q4: What if my room has high ceilings?
A: Increase your heating load estimate by 10-25% depending on ceiling height.

Q5: Does this account for heat loss through windows?
A: No, your heating load calculation should include window area and quality for accurate results.
