1. What is a Radiator Output Calculator?

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

Purpose: It helps HVAC professionals and homeowners understand the power output of existing radiators in different units.

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 power.

3. Importance of Radiator Output Calculation

Details: Understanding radiator output helps in system balancing, energy efficiency assessments, and comparing different heating systems.

4. Using the Calculator

Tips: Enter the radiator's heat output in BTU/h (typically found on the radiator's specification plate). 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 can I find my radiator's BTU/h rating?
A: Check the manufacturer's label on the radiator, specification sheet, or product documentation.

Q3: Is 3412 an exact conversion factor?
A: It's the standard conversion (1 kW = 3412.142 BTU/h) used in HVAC calculations.

Q4: Can I use this for other heat emitters?
A: Yes, this conversion works for any device that outputs heat in BTU/h (convectors, baseboard heaters, etc.).

Q5: How accurate is this calculation?
A: The conversion is mathematically exact, but actual radiator output may vary based on operating conditions.
