1. What is an Electric Radiator BTU Calculator?

Definition: This calculator converts electric power in watts to BTU/h output for electric radiators.

Purpose: It helps determine the heating capacity of electric radiators in BTU/h based on their power consumption.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — BTU output per hour (BTU/h)
• \( P \) — Electric power input (watts)

Explanation: The formula converts watts to BTU/h using the conversion factor of 3412 BTU/h per watt.

3. Importance of BTU Calculation

Details: Knowing the BTU output helps in selecting the right size radiator for a space and comparing heating efficiency.

4. Using the Calculator

Tips: Enter the electric power consumption in watts. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 as the conversion factor?
A: 1 watt equals 3.412 BTU/h, so 3412 is the conversion factor for 1000 watts (1 kW) to BTU/h.

Q2: Is this accurate for all electric radiators?
A: Yes, since electric radiators convert 100% of electrical energy to heat energy.

Q3: How does this relate to room size?
A: Typically, you need about 20 BTU/h per square foot of space, but this varies by climate and insulation.

Q4: Can I use this for other electric heaters?
A: Yes, this applies to any electric heating device where all energy is converted to heat.

Q5: What's the difference between BTU and BTU/h?
A: BTU measures energy, while BTU/h measures power (energy per time).
