Mastertemp is dead, need rec for new heater, Please!
So we had a Pentair Mastertemp 400. 3 1/2 years old. The tub holding the heatexchanger and burner rusted through, and the heat melted the manifold and the manifold baffle. I could fix it, but I think I'm just going to replace it. This thing has been nothing but trouble: new motherboard, temp sensor, pressure sensor, transformer. Always breaks right before a big party. I have to cobble it together with a minimum of leakage to get it to survive through a party on Friday.
Anyway, I need a recommendation for a new 400K btu heater, We use it a LOT here in NY. What is the best constructed, most reliable unit?
