1. What is a Size Electric Heater Calculator?

Definition: This calculator determines the electric heater size (Q) in watts based on the required size input.

Purpose: It helps in selecting the appropriate electric heater size for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heater size (watts)
• \( Size \) — Required heater size (watts)

Explanation: The calculator directly converts the input size to the heater size output.

3. Importance of Heater Size Calculation

Details: Proper heater sizing ensures efficient heating, energy savings, and prevents equipment overload.

4. Using the Calculator

Tips: Enter the required heater size in watts. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect heater size requirements?
A: Room size, insulation quality, desired temperature, and outdoor temperature all affect sizing.

Q2: How do I convert watts to BTUs?
A: Multiply watts by 3.412 to get BTUs per hour.

Q3: What's a typical heater size for a small room?
A: A 1500W heater is common for a 150 sq ft well-insulated room.

Q4: Should I oversize my heater?
A: Generally no, as this can lead to short cycling and inefficiency.

Q5: How does voltage affect heater size?
A: Higher voltage heaters can deliver more power (watts) with less current.
