Hi dear

I recently installed pool heater but even after 40 hours non stop operation water temperature is not sufficient for swimming. Pool size is 12x52 and is avg 4.5 feet deep. Temp setting is at max.

I shifted all filter output to heater that than goes to pool.

Is this heater sufficient for this capacity?

In my area temp at night is 45f at night and 75f highest during day.

Pls guide.

I believe the Pentair mini max is 100,000 BTU gas pool heater.  Your pool is approximately 21,000 gallons.  100,000 BTU is too small for your size pool.  250,000 BTU unit would be more appropriate.

Best, Asa Strong
