1. What is a Radiator Output Calculator?

Definition: This calculator converts a radiator's heat output rating from BTU/h to kilowatts (kW).

Purpose: It helps heating engineers and homeowners understand radiator performance 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
• 3412 — Conversion factor (1 kW = 3412 BTU/h)

Explanation: The radiator's BTU rating is divided by 3412 to convert it to kilowatts, the standard unit for heating system specifications.

3. Importance of Radiator Output Calculation

Details: Accurate output calculations ensure proper heating system design, energy efficiency, and comfortable room temperatures.

4. Using the Calculator

Tips: Enter the radiator's BTU rating (typically found on manufacturer specifications). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU to kW?
A: Many heating systems and energy calculations use kW as the standard unit, making comparisons and system design easier.

Q2: Where do I find my radiator's BTU rating?
A: Check manufacturer documentation, product labels, or specification sheets. Many radiators have this printed on them.

Q3: Is 3412 always the conversion factor?
A: Yes, this is the standard conversion (1 kW = 3412.142 BTU/h) though we use 3412 for simplicity.

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

Q5: What's a typical radiator output?
A: Residential radiators typically range from 0.5-3 kW (1,700-10,000 BTU/h), depending on size and type.
