1. What is a Radiator Output Calculator?

Definition: This calculator converts heat output from BTU/h to kilowatts (kW), which is the standard unit for radiator power ratings.

Purpose: It helps HVAC professionals and homeowners compare and understand radiator specifications across different measurement systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Radiator Output Calculation

Details: Accurate conversion ensures proper radiator sizing for heating systems and energy efficiency calculations.

4. Using the Calculator

Tips: Simply enter the radiator's heat output in BTU/h to get the equivalent value in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU/h to kW?
A: kW is the standard international unit for power, making it easier to compare radiator specifications globally.

Q2: Is 3412 always the conversion factor?
A: Yes, this is the exact conversion (1 kW = 3412.142 BTU/h) based on the international steam table BTU.

Q3: Where do I find the BTU rating?
A: Check your radiator's specification plate, product documentation, or manufacturer's website.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact, but actual radiator performance may vary based on operating conditions.

Q5: Can I convert kW back to BTU?
A: Yes, multiply kW by 3412 to get BTU/h (reverse of this calculation).
