1. What is a Radiator Output Calculator?

Definition: This calculator estimates the heat output of a radiator based on its dimensions and temperature difference.

Purpose: It helps HVAC professionals and homeowners determine the heating capacity of radiators for proper system sizing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Output \) — Heat output in BTU
• \( Length \) — Radiator length in feet
• \( Width \) — Radiator width in feet
• \( Height\ Factor \) — Multiplier for radiator height
• \( \Delta T \) — Temperature difference between radiator and room (°F)

Explanation: The dimensions determine the radiator's surface area, which is multiplied by the height adjustment and temperature difference to calculate heat output.

3. Importance of Radiator Output Calculation

Details: Proper output estimation ensures adequate heating capacity, energy efficiency, and comfortable room temperatures.

4. Using the Calculator

Tips: Enter the radiator dimensions in feet, height factor (default 1.0), and temperature difference (default 50°F). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is Delta T in radiator calculations?
A: Delta T is the temperature difference between the radiator surface and the room air temperature.

Q2: How do I determine the height factor?
A: The height factor adjusts for taller radiators. Standard radiators use 1.0, while taller models may use 1.1-1.3.

Q3: Can I use this for metric measurements?
A: The calculator currently uses feet and °F. For metric, convert to meters and °C, then multiply the result by 0.293 for kW.

Q4: What's a typical Delta T value?
A: Most systems use 50-70°F difference, but this depends on your heating system's water temperature.

Q5: Does this include heat loss factors?
A: No, this is a basic calculation. For precise results, consider pipe losses, room insulation, and radiator material.
