1. What is a Radiator Output Calculator?

Definition: This calculator determines the required heat output for each radiator in a central heating system based on total room heat loss and number of radiators.

Purpose: It helps HVAC professionals and homeowners properly size radiators for efficient and effective room heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( O \) — Required output per radiator (BTU)
• \( H \) — Total room heat loss (BTU)
• \( N \) — Number of radiators in the room

Explanation: The total heat loss is divided equally among all radiators in the room to determine each radiator's required output.

3. Importance of Proper Radiator Sizing

Details: Correct radiator output ensures comfortable room temperatures, energy efficiency, and prevents system overloading.

4. Using the Calculator

Tips: Enter the total room heat loss in BTU and the number of radiators you plan to install. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my room's heat loss?
A: Use a professional heat loss calculation or online heat loss calculator that considers room size, insulation, windows, and climate.

Q2: Can I use kW instead of BTU?
A: Yes, but ensure all values use the same unit (1 kW = 3412 BTU). The calculator works with any consistent unit.

Q3: Should all radiators have equal output?
A: Not necessarily. You may want larger radiators near windows or exterior walls where heat loss is greater.

Q4: What if my radiators have different outputs?
A: The calculator provides an average. Adjust individual radiators based on their locations and specific needs.

Q5: Does this account for radiator type or placement?
A: No, this is a basic calculation. Consult an HVAC professional for complex installations.
