BTU Conversion Formula:
From: | To: |
Definition: This calculator converts electrical power in watts to heat output in BTUs per hour for electric heating systems.
Purpose: It helps determine the heating capacity of electric heaters and heating elements.
The calculator uses the formula:
Where:
Explanation: The formula converts watts to BTUs per hour using the conversion factor of 3412 BTU/h per watt.
Details: Proper heat output estimation ensures adequate heating capacity for spaces and helps in selecting appropriate heating equipment.
Tips: Enter the electrical power in watts. The value must be > 0.
Q1: Why is the conversion factor 3412?
A: 1 Watt = 3.412 BTU/h, so the factor comes from this standard conversion ratio.
Q2: Does this work for all electric heaters?
A: Yes, this applies to all electric resistance heating systems which are 100% efficient at converting electricity to heat.
Q3: How accurate is this calculation?
A: It's mathematically precise for electric resistance heating, but doesn't account for heat pump systems which can have higher efficiency.
Q4: Can I use this for three-phase heaters?
A: Yes, as long as you input the total power consumption in watts, the calculation remains the same.
Q5: How does this relate to heating area size?
A: While this gives heat output, you'll need additional calculations (30-40 BTU/sq ft typically) to determine appropriate heating for a space.
