For Indoor Pools Model I
1. Calculate the surface area of the pool in square feet.
2. Refer to the selection chart for either an indoor or outdoor heater.
3. Find the closest square footage in the 10° F (6° C) Temperature Difference column, and the heater models which correspond to it. For normal conditions,
Pentair recommends using the 10° F Temperature Difference columns; this will provide a temperature increase of approximately 6° F per 24 hour period.
