1. What is Radiant Heating BTU Calculation?

The Radiant Heating BTU calculation determines the required British Thermal Unit output for underfloor heating systems based on floor area and insulation factors. This ensures optimal heating performance and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the radiant heating formula:

Where:

• \( Floor\ Area \) — Total floor area in square feet (ft²)
• \( BTU\ Factor \) — Output per square foot (12-15 BTU/ft²)

Explanation: The calculation provides the hourly BTU output required to adequately heat the specified floor area using radiant underfloor heating systems.

3. Importance of BTU Calculation

Details: Accurate BTU calculation is essential for proper sizing of radiant heating systems, ensuring comfortable temperatures, energy efficiency, and preventing system overloading or underperformance.

4. Using the Calculator

Tips: Enter floor area in square feet and select appropriate BTU factor based on insulation quality and climate conditions. Higher factors (14-15) for poorly insulated areas or colder climates.

5. Frequently Asked Questions (FAQ)

Q1: What BTU factor should I use?
A: Use 12-13 BTU/ft² for well-insulated spaces, 14-15 BTU/ft² for average to poor insulation or colder climates.

Q2: How does floor covering affect BTU requirements?
A: Thick carpets or insulating underlays may require higher BTU factors, while tile or concrete floors may need standard factors.

Q3: Can this calculator be used for room additions?
A: Yes, calculate each room separately and sum the BTU requirements for whole-house systems.

Q4: What about ceiling height variations?
A: Standard calculation assumes 8-foot ceilings. For higher ceilings, increase BTU factor by 1-2 points per additional foot.

Q5: Is this suitable for commercial applications?
A: This calculator is designed for residential use. Commercial applications may require professional engineering assessment.
