First of all I would like to say that this forum has a wealth of knowledge and is very helpful!
I have an existing Laars pool heater which I am looking to replace. I am looking at Pool Heater Jandy Lxi. What has been people's experience with this line? Also, I have noticed that the heat exchangers come in varying alloys - Bronze copper, cupro nickel and cupro nickel? What environmental variables would affect your alloy choice? Also they further delineate their product line by ASME certification - is this important?
Appreciate the help.
