1. What is a Hot Water Tank Calculator?

Definition: This calculator estimates the required hot water tank size based on daily water usage and a sizing factor.

Purpose: It helps homeowners and plumbers determine the appropriate tank size for efficient hot water supply.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of hot water tank (liters)
• \( D \) — Daily hot water usage (liters)
• \( F \) — Factor (dimensionless)

Explanation: The daily water usage is multiplied by a factor to account for peak demand periods and ensure adequate supply.

3. Importance of Proper Tank Sizing

Details: Correct tank sizing ensures energy efficiency, meets household demand, and prevents unnecessary costs from oversized tanks.

4. Using the Calculator

Tips: Enter your estimated daily hot water usage in liters and the sizing factor (default 1.5). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why do we need a sizing factor?
A: The factor accounts for peak usage times when hot water demand exceeds the average daily usage.

Q2: What's a typical daily usage for a family?
A: Average households use about 50-80 liters per person per day, but this varies with lifestyle.

Q3: When would I change the factor?
A: Use higher factors (1.8-2.0) for households with simultaneous high demand, or lower (1.2-1.4) for efficient systems.

Q4: How do I estimate my daily usage?
A: Track appliance use (showers: 30-60L, dishwasher: 15-30L, washing machine: 40-60L per cycle).

Q5: Does this include heat loss considerations?
A: No, this calculates volume only. Insulation and heating capacity affect performance but not tank size.
