1. What is a Heating Radiator Size Calculator?

Definition: This calculator determines the required radiator size based on room heat loss and radiator output per unit.

Purpose: It helps homeowners and heating engineers select properly sized radiators for efficient room heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Radiator size (number of units)
• \( H \) — Heat loss (Watts)
• \( O \) — Output per radiator unit (Watts/unit)

Explanation: The total heat loss is divided by the output of each radiator unit to determine how many units are needed.

3. Importance of Proper Radiator Sizing

Details: Correct sizing ensures efficient heating, prevents energy waste, and maintains comfortable room temperatures.

4. Using the Calculator

Tips: Enter the room's heat loss in Watts and the radiator's output per unit in Watts. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my room's heat loss?
A: Use a heat loss calculator or consult a heating engineer who can perform a proper heat loss calculation.

Q2: Where can I find radiator output specifications?
A: Output is typically listed in the radiator's technical specifications (usually in Watts at ΔT 50°C).

Q3: Should I round up the result?
A: Yes, always round up to the nearest whole number to ensure adequate heating capacity.

Q4: Does this account for different room types?
A: No, the heat loss value should already account for room characteristics (size, insulation, windows, etc.).

Q5: What's a typical output for radiator units?
A: Standard single panel radiators output about 80-100W per section, while double panel models output 150-200W per section.
