1. What is a Wood Burner kW Calculator?

Definition: This calculator converts the heat output of a wood burner from BTU/h to kilowatts (kW).

Purpose: It helps homeowners and heating professionals understand the power output of wood burners in standard kW units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power output in kilowatts (kW)
• \( Q_{btu} \) — Heat output in British Thermal Units per hour (BTU/h)

Explanation: The conversion factor 3412 represents the number of BTU/h equivalent to 1 kW of power.

3. Importance of kW Calculation for Wood Burners

Details: Knowing the kW output helps in sizing the wood burner appropriately for your space and comparing it with other heating systems.

4. Using the Calculator

Tips: Enter the heat output in BTU/h (typically found in your wood burner's specifications). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU/h to kW?
A: kW is the standard unit for power in most countries outside the US, making it easier to compare with other heating systems.

Q2: Where do I find my wood burner's BTU/h rating?
A: Check the manufacturer's specifications, product manual, or nameplate on the unit.

Q3: What's a good kW range for a home wood burner?
A: Typically 5-15 kW for most homes, depending on insulation and room size (1 kW heats about 10 m² in a well-insulated space).

Q4: Does this account for efficiency?
A: No, this calculates theoretical output. Actual heat delivered depends on the burner's efficiency rating.

Q5: Can I convert kW back to BTU/h?
A: Yes, multiply kW by 3412 to get BTU/h.
