1. What is a Radiator Output Calculator UK?

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

Purpose: It helps heating engineers and homeowners convert between these common UK radiator measurement units.

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: Proper radiator sizing ensures efficient heating system performance, energy efficiency, and comfortable room temperatures.

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: UK radiators are often rated in both units, and conversions are needed for system design and comparisons.

Q2: What's a typical radiator output?
A: Standard UK radiators range from 600-10,000 BTU/h (0.18-2.93 kW), depending on size and type.

Q3: How accurate is this conversion?
A: The conversion factor is mathematically exact (1 kW = 3412.14 BTU/h), rounded to 3412 for practical use.

Q4: When would I need this calculation?
A: When replacing radiators, designing heating systems, or comparing radiator specifications.

Q5: Does this account for radiator efficiency?
A: No, this is a direct unit conversion. Actual heat output may vary based on system conditions.
