1. What is a Radiant Heat Loop Calculator?

Definition: This calculator estimates the length of tubing needed for radiant heat systems based on floor area and tubing spacing.

Purpose: It helps HVAC professionals and installers determine how much tubing is required for radiant floor heating projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Loop length (meters)
• \( A \) — Area to be heated (square meters)
• \( S \) — Tubing spacing (meters)

Explanation: The area is divided by the spacing to determine the total length of tubing needed.

3. Importance of Loop Length Calculation

Details: Proper loop length estimation ensures even heat distribution, proper system performance, and accurate material purchasing.

4. Using the Calculator

Tips: Enter the area in square meters and tubing spacing in meters (default 0.2m). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical tubing spacing?
A: Most radiant heat systems use 0.15m to 0.3m spacing, with 0.2m being common for residential applications.

Q2: Does this account for manifold connections?
A: No, this calculates only the tubing in the heated area. Add extra length for connections to manifolds.

Q3: How do I convert from square feet?
A: Multiply square feet by 0.0929 to get square meters before using the calculator.

Q4: Should I add extra length for safety?
A: Yes, consider adding 5-10% to the calculated length for installation contingencies.

Q5: Does spacing affect heat output?
A: Yes, closer spacing provides more heat output but requires more tubing.
