1. What is a BTU Calculator for Radiators?

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

Purpose: It helps determine the heating capacity of radiators, which is often specified in BTU/h in product specifications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BTU \) — British Thermal Units per hour (BTU/h)
• \( kW \) — Power input in kilowatts

Explanation: 1 kW is equivalent to 3412 BTU/h, as this is the standard conversion factor between these units of power.

3. Importance of BTU Calculation

Details: Knowing the BTU output helps in selecting the right radiator size for a room, ensuring efficient heating and energy use.

4. Using the Calculator

Tips: Simply enter the radiator's power input in kilowatts (kW). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kW to BTU?
A: While kW is the standard metric unit, BTU is commonly used in radiator specifications, especially in certain regions.

Q2: What's a typical BTU output for home radiators?
A: Residential radiators typically range from 5,000 to 15,000 BTU/h, depending on size and design.

Q3: Can I convert BTU back to kW?
A: Yes, divide BTU by 3412 to get kW (kW = BTU ÷ 3412).

Q4: Does this account for radiator efficiency?
A: No, this is a direct unit conversion. Actual heat output may vary based on radiator efficiency.

Q5: How do I find my radiator's kW rating?
A: Check the product specifications or nameplate on the radiator unit.
