1. What is a Storage Heater Room Size Calculator?

Definition: This calculator estimates the required storage heater capacity (in kWh) based on room volume and a heating factor.

Purpose: It helps homeowners and heating professionals determine the appropriate storage heater size for a given room volume.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kWh \) — Storage heater capacity (kilowatt-hours)
• \( V \) — Room volume (cubic meters)
• \( F \) — Heating factor (kWh per cubic meter)

Explanation: The room volume is multiplied by a heating factor that accounts for insulation quality and desired temperature.

3. Importance of Proper Heater Sizing

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

4. Using the Calculator

Tips: Enter the room volume in cubic meters and heating factor (default 0.04 kWh/m³ for average insulation). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate room volume?
A: Multiply room length × width × height in meters. For irregular rooms, divide into rectangular sections.

Q2: What heating factor should I use?
A: Typical values are 0.03-0.05 kWh/m³ (0.03 for well-insulated, 0.05 for poorly insulated rooms).

Q3: Does this account for room usage?
A: No, for frequently used rooms you may need to increase capacity by 10-20%.

Q4: What about room orientation?
A: North-facing rooms may need 10-15% more capacity than calculated.

Q5: How accurate is this calculation?
A: It provides a good estimate but consult a heating professional for precise requirements.
