1. What is an Existing Radiator Output Calculator?

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

Purpose: It helps heating engineers and homeowners determine the power output of existing radiators when working with systems that use kW measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Radiator 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 equivalent to 1 kW of power.

3. Importance of Radiator Output Calculation

Details: Accurate conversion between units is essential when upgrading heating systems, comparing radiator specifications, or designing new installations.

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: Many modern heating systems and specifications use kW, while older radiators often have BTU/h ratings.

Q2: Where can I find my radiator's BTU/h rating?
A: Check the manufacturer's label on the radiator, product documentation, or look up the model number online.

Q3: Is the conversion factor always 3412?
A: Yes, 1 kW is always equal to 3412.142 BTU/h by definition.

Q4: Can I use this for other heat output conversions?
A: Yes, this works for any device where you need to convert heat output from BTU/h to kW.

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