1. What is a Radiator Heat Output Calculator?

Definition: This calculator converts radiator heat output from BTU/h (British Thermal Units per hour) to kW (kilowatts).

Purpose: It helps HVAC professionals and homeowners compare and understand radiator specifications in different units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Heat 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 in 1 kW of thermal power.

3. Importance of Heat Output Calculation

Details: Accurate heat output conversion ensures proper radiator sizing for efficient heating system design and energy consumption.

4. Using the Calculator

Tips: Enter the radiator's heat output in BTU/h. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between BTU/h and kW?
A: Different regions use different units - North America typically uses BTU/h while Europe uses kW. Conversion allows comparison.

Q2: Is 3412 an exact conversion factor?
A: Yes, 1 kW is exactly equal to 3412.142 BTU/h by definition.

Q3: Where do I find my radiator's BTU/h rating?
A: Check the manufacturer's specifications, usually on the radiator's label or technical documentation.

Q4: How many kW is a typical radiator?
A: Residential radiators range from 0.5-3 kW (1,700-10,200 BTU/h), depending on size and type.

Q5: Does this work for other heating appliances?
A: Yes, the same conversion applies to boilers, furnaces, and any heating equipment's output rating.
