1. What Is a Radiator Output Calculator?

Definition: This calculator converts a radiator's BTU/h rating to kilowatts (kW), the standard unit for measuring heat output.

Purpose: It helps homeowners and heating engineers understand and compare radiator outputs in different measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Radiator output in kilowatts
• \( Q_{btu} \) — Radiator rating in BTU per hour

Explanation: The conversion factor 3412 represents the number of BTUs in one kilowatt-hour.

3. Importance of Radiator Output Calculation

Details: Understanding radiator output helps ensure proper heating system design, energy efficiency, and room comfort.

4. Using the Calculator

Tips: Enter the radiator's BTU/h rating (usually found on the product label or 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 heating systems in many countries, making it easier to compare with boiler outputs and heating requirements.

Q2: Where do I find my radiator's BTU rating?
A: Check the product label, manufacturer's website, or installation manual. For older radiators, you may need to estimate based on size and type.

Q3: What's a typical radiator output?
A: Standard radiators range from 0.5-2.5 kW (1,700-8,500 BTU/h), depending on size and type.

Q4: How accurate is this conversion?
A: The conversion is mathematically precise, but actual heat output may vary based on water temperature and system conditions.

Q5: Can I convert kW back to BTU?
A: Yes, multiply kW by 3412 to get BTU/h (the inverse of our formula).
