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. Don't be fooled by their "Heavy-Duty" label. They are a fan-forced heater.
Models: Mastertemp 125, 200, 300, 400
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
Yet another re-branded Pentair Mastertemp, this time with a different outside casing. The internals are identical.
Models: Max-E-Therm 200, 300, 400
We carry almost all spare parts on-board, and were an Authorized Service Agent. Unfortunately Pentair Australia proved to be one of the very worst companies we have dealt with. They will say and do almost anything to avoid warranty (We've seen it first-hand). We only supply these heaters where space is a requirement, and handle all Warranties directly. We do not recommend Pentair Heaters for most installations.
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 are also more prone to issues with water chemistry.
