1. What is a Storage Heater Size Calculator?

Definition: This calculator estimates the appropriate size (in kW) of a storage heater needed for a room based on its volume.

Purpose: It helps homeowners and heating professionals determine the correct storage heater capacity for efficient room heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kW \) — Storage heater size (kilowatts)
• \( V \) — Room volume (cubic meters)
• \( 0.04 \) — Standard multiplier for storage heater sizing

Explanation: The room volume is multiplied by 0.04 kW per cubic meter to determine the appropriate storage heater capacity.

3. Importance of Proper Storage Heater Sizing

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

4. Using the Calculator

Tips: Measure your room's length, width, and height to calculate volume (L × W × H in meters). Enter the volume in cubic meters.

5. Frequently Asked Questions (FAQ)

Q1: Why is 0.04 used as the multiplier?
A: This is a standard value representing 40 watts per cubic meter (0.04 kW/m³) for typical well-insulated rooms.

Q2: When should I adjust the multiplier?
A: Use 0.05 (50W/m³) for poorly insulated rooms or 0.03 (30W/m³) for very well insulated spaces.

Q3: How do I calculate room volume?
A: Multiply room length × width × height in meters. For irregular rooms, divide into regular shapes and sum volumes.

Q4: Does this account for room usage?
A: No, consider adding 10-20% for bathrooms or rooms with high heat loss through windows.

Q5: What about room shape and window area?
A: The basic calculation assumes average conditions. For rooms with large windows or unusual shapes, consult a heating specialist.
