1. What is a Radiator BTU Output Calculator?

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

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: 1 kW of power is equivalent to 3412 BTU/h of heat output.

3. Importance of BTU Output Calculation

Details: Proper BTU calculation ensures adequate heating capacity for rooms, energy efficiency, and correct radiator sizing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert kW to BTU/h?
A: BTU/h is a common measurement for heating capacity in many countries, while kW is the standard power unit.

Q2: What's the conversion factor 3412?
A: It's the exact conversion from kilowatts to BTU per hour (1 kW = 3412.142 BTU/h).

Q3: How do I find my radiator's kW rating?
A: Check the manufacturer's specifications or product label for the kW output.

Q4: Does this account for heat loss?
A: No, this is the theoretical output. Actual heating needs may be higher due to insulation factors.

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