1. What is a Floor Heating Cable Calculator?

Definition: This calculator estimates the heat output in BTUs for electric floor heating cables based on their power input in watts.

Purpose: It helps homeowners and contractors determine the heating capacity of electric floor heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heat output (BTU per hour)
• \( P \) — Power input (Watts)
• 3412 — Conversion factor from watts to BTU/h

Explanation: The power input in watts is multiplied by the standard conversion factor to determine the heat output in British Thermal Units per hour.

3. Importance of Heat Output Calculation

Details: Proper heat output estimation ensures comfortable room temperatures, energy efficiency, and proper system sizing for your space.

4. Using the Calculator

Tips: Enter the power rating of your floor heating cable in watts. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the 3412 conversion factor?
A: This is the standard conversion from watts to BTU/h (1 watt = 3.412 BTU/h).

Q2: How do I find my heating cable's power rating?
A: Check the product specifications or nameplate on your heating cable system.

Q3: Does this account for heat loss?
A: No, this calculates theoretical output. Actual heating performance may vary based on installation and insulation.

Q4: What's a typical wattage for floor heating?
A: Most systems range from 8-15 watts per square foot depending on the application.

Q5: Can I use this for other electric heating systems?
A: Yes, the same formula applies to any electric heating system.
