For my fellow poolpros in extreme cold climates, what main heater brand do you guys go with?
I've been installing Mastertemps for a while now, and while there are a fair share of other issues with them (those bad stack flu's for years, bad exhaust welds during covid, ect. ect.) I figure any brand is going to have little problems like that. Right now mastertemp seems pretty smoothed out aside from one persistent problem: For units that run in the winter (down to -10 degrees where I'm at) the condensation from the exhaust blows back onto the unit and corrodes the sfs and the control board and consistently breaks those components in the middle of the winter which results in a midnight emergency call for me to repair a heater. And yes the heaters are running the water at 75-90 degrees minimum, but when it is that cold out (below 20) I've found that no temperature of water will stop them from billowing steam the whole time.
I'm talking to our Hayward rep and he's promising that their heaters don't ever have issues with condensate damage from winter running in our area, but ofcourse he's gonna say that it's his job. Figure the best place to get info would be here, so anybody in cold climates have a good heater figured out that doesn't destroy itself in cold weather?
Thanks for any input!
