Pool and Spa Heater Service, Repair, Installation and Spare Parts
Pentair Mastertemp / Waterco Turbotemp Gas Heater Services
Pentair Mastertemp
Pentair Mastertemp pool heaters were popular for a few years by many pool builders. As they are complex and not many people know how to work on these, many builders have moved on to other brands. We see more blown heat exchangers on these than any other heater.
Models: Mastertemp 125 HD, 200 HD, 300 HD, 400 HD
Waterco Turbotemp
Waterco Turbotemps were simply a re-branded Pentair Mastertemp. Waterco has moved on from these heaters. Waterco now recommends a different brand of heater.
Models: Turbotemp 125, 200, 300, 400
Sta-Rite Max-E-Therm
Yet another re-branded Pentair Mastertemp, this time with a different outside casing. The internals are identical.
Models: Max-E-Therm 200, 300, 400
About Pentair Heaters
We carry almost all spare parts on-board, and were an Authorized Service Agent. We only supply these heaters where space is a requirement, and handle all Warranties directly. We do not recommend Pentair Heaters for most installations.
More Information
They use a finely tuned fan-forced blower for efficiency. Unfortunately they succumb to any problem with water flow and gas supply pressure. Their Heat Exchangers appear to be more prone to issues with water chemistry.
