Product details
The Pentair 38000-0007S is the thermal regulator for the Max-E-Therm heater water system, supplied with its clip. Our category data lists it with the Sta-Rite Max-E-Therm SR200, SR333 and SR400.
What it does
The thermal regulator meters water through the heat exchanger so the exchanger works in the range it was built for rather than being flooded with cold water. Get that wrong and the heater either struggles to raise temperature or runs cold enough inside to condense on the exchanger, which is not a condition it survives for long.
When to suspect it
Slow or inconsistent heating with a clean filter and good flow points at the regulator. Because Sta-Rite is a Pentair brand, the service part for a Sta-Rite badged Max-E-Therm carries the Pentair number 38000-0007S.
