1. What is a Radiator BTU Calculator?

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

Purpose: It helps determine the heating capacity of radiators for proper sizing in heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The conversion factor 3412 represents the number of BTUs equivalent to 1 kWh of energy.

3. Importance of BTU Calculation

Details: Proper BTU calculation ensures adequate heating capacity for spaces, energy efficiency, and system balance.

4. Using the Calculator

Tips: Enter the radiator's power rating in kW. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kW to BTU/h?
A: BTU/h is a common unit for radiator specifications in some regions, while kW is used in others.

Q2: What's the exact conversion factor?
A: 1 kW = 3412.142 BTU/h (rounded to 3412 for practical calculations).

Q3: Does this account for radiator efficiency?
A: No, this calculates theoretical output. Actual heat output may vary based on efficiency.

Q4: How do I find my radiator's kW rating?
A: Check manufacturer specifications or product labels.

Q5: What's a typical BTU requirement per room?
A: Approximately 20 BTU per square foot, but this varies by climate and insulation.
