My water isn't heating up that well. I can't even get it to register 140 degrees. I was told to ask you about the preheater on the prochems. They said you would know the difference between running with one vs without one.
I bypassed my preheater on my prochem legend. I was told by the guy that worked on it that it doesn't make a big difference so we bypassed it since it was leaking a little. I have a brand new blue baron aftermarket heat exchanger.
