1. What is a Bradford White Water Heater Sizing Calculator?

Definition: This calculator determines the appropriate water heater tank size based on household size and estimated water usage per person.

Purpose: It helps homeowners and plumbers select the right Bradford White water heater capacity for optimal performance and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Size = Family \times Gal\,per\,Person \]

Where:

Explanation: The family size is multiplied by the average hot water consumption per person to determine total capacity needs.

3. Importance of Proper Water Heater Sizing

Details: Correct sizing ensures adequate hot water supply while avoiding energy waste from an oversized unit or insufficient capacity from an undersized one.

4. Using the Calculator

Tips: Enter the number of people in your household and gallons per person (default 12 gal/person). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 12 gallons per person the default?
A: This is Bradford White's recommended average for typical residential use, accounting for showers, dishes, and laundry.

Q2: When should I adjust the gallons per person value?
A: Increase if your household has high water usage (15-20 gal) or decrease for low usage (8-10 gal).

Q3: Does this account for simultaneous usage?
A: The calculation includes a buffer for peak usage times. For multiple bathrooms, consider adding 10-20% to the result.

Q4: How does this work for tankless water heaters?
A: Tankless units are sized by flow rate (GPM) rather than tank capacity. Use our Tankless Sizing Calculator for those models.

Q5: What about energy factor considerations?
A: This calculates capacity only. For energy efficiency, consult Bradford White's Energy Guide labels.
