Performance Guide

1. Confirm the color that aligns with your geographical location.

2. Calculate your maximum hot water demand in total gallons per minute (GPM) based on how many applications in your home will be used at the same time.


For example, 1 water saver shower head + 1 hand washing sink = 2 GPM

3. Based on your location's color (Step 1) and your maximum GPM demand (Step 2), confirm the unit will supply sufficient water to accommodate your hot water demand throughout the seasons of the year.
