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 area.

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)
• \( Area \) — Room area (square meters)

Explanation: The calculation assumes a standard requirement of 0.1 kW per square meter for storage heaters in well-insulated rooms.

3. Importance of Correct Heater Sizing

Details: Proper sizing ensures efficient heating, avoids energy waste, and maintains comfortable room temperatures.

4. Using the Calculator

Tips: Simply enter the room area in square meters. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 0.1 kW per m²?
A: This is a standard rule of thumb for well-insulated rooms. Poor insulation may require 0.15 kW/m².

Q2: What if my room has high ceilings?
A: For rooms with ceilings over 2.4m, consider increasing the calculated size by 10-20%.

Q3: Does this work for all room types?
A: Bathrooms may need slightly more (0.12 kW/m²) while bedrooms may need slightly less (0.08 kW/m²).

Q4: How accurate is this calculation?
A: It provides a good estimate but consult a heating professional for precise requirements.

Q5: What about room orientation and windows?
A: North-facing rooms or those with large windows may need 10-15% more capacity.
