Selection of the right size OTF/ITF Heater
There are many factors related to proper sizing of Pool Heaters. We recommend you contact your installing dealer for
help in determining the correct size for your particular application.

NOTES: 1. These heat losses are based on an assumed wind velocity at the water surface of 5 m.p.h. and an ambient
temperature of 60°F.
2. Where surface area and gallons do not coincide, surface area must take precedence.
