How to Properly Size Your Indirect Water Heater

Use the First Hour Rating (FHR) to properly size your Indirect Water Heater. The FHR is the amount of hot water in gallons the water heater can supply in the first hour of operation (starting with a tank full of hot water). The FHR is dependent on tank capacity, source of heat, and the size of the burner.

The Indirect Water Heater and Boiler sizing charts can be found on pages 23 and 24. Locate your Indirect Water Heater and Boiler along with your required First Hour Rating. This will also determine the flow needed between the Indirect Water Heater and Boiler.

NOTICE

The charts utilize only the upper boiler coil and the upper half of the tank.
