1. What is a Radiant Heat Load Calculator?

Definition: This calculator estimates the radiant heat load based on the area and load density.

Purpose: It helps HVAC professionals and engineers determine the heat load for radiant heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Load} = \text{Area} \times \text{Load Density} \]

Where:

\( \text{Load} \) — Radiant heat load (Watts)
\( \text{Area} \) — Surface area (square meters)
\( \text{Load Density} \) — Heat load per unit area (Watts/square meter)

Explanation: The area is multiplied by the load density to calculate the total heat load required.

3. Importance of Radiant Heat Load Calculation

Details: Proper heat load estimation ensures efficient system design, energy savings, and comfortable indoor environments.

4. Using the Calculator

Tips: Enter the area in square meters and load density (default 100 W/m²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical load density for radiant heating?
A: Residential spaces typically use 80-100 W/m², while commercial spaces may use 100-150 W/m².

Q2: How do I determine the correct load density?
A: Consider factors like insulation, climate, room type, and desired temperature.

Q3: Does this include heat loss calculations?
A: No, this is a basic calculation. For precise results, perform detailed heat loss analysis.

Q4: Can I use this for cooling load calculations?
A: No, cooling loads require different calculations accounting for humidity and solar gain.

Q5: How accurate is this calculator?
A: It provides a rough estimate. For critical applications, consult a professional HVAC engineer.
