Wood Burning Stove Size Calculator

Stove Size Formula:

\[ P_{kW} = \frac{Q_{btu}}{3412} \]

Stove Size (kW):

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

Purpose: It helps homeowners and heating professionals properly size wood stoves for efficient heating.

The calculator uses the formula:

\[ P_{kW} = \frac{Q_{btu}}{3412} \]

Where:

Explanation: The conversion factor 3412 represents the number of BTUs per hour equivalent to 1 kilowatt of power.

Details: Correctly sized stoves ensure efficient heating, proper fuel consumption, and prevent overheating or underheating your space.

Tips: Enter the heat output in BTU/h (typically found in stove specifications). The value must be > 0.

Q1: Why convert BTU/h to kW?
A: kW is a more standard measurement for stove sizing in many countries and makes comparison easier.

Q2: What's a typical BTU output for home stoves?
A: Residential stoves typically range from 20,000 to 80,000 BTU/h (6-23 kW).

Q3: How do I determine the right size for my home?
A: As a rule of thumb, you need about 5 kW per 1,000 sq ft of well-insulated space.

Q4: Does this account for stove efficiency?
A: No, this is a direct conversion. Actual heat output depends on stove efficiency ratings.

Q5: Where can I find my stove's BTU rating?
A: Check the manufacturer's specifications, usually on the rating plate or in the manual.
