Help needed - Replacement pool/spa heater

[Geeper]

Mark,

Thanks for your reply. We have a 1.5" line running just under 50 feet. My pool guys stated he would not have installed this particular heater if it was up to him and that he would have installed a larger line from the meter. In the end, neither of these really matter since our line "should" be big enough and we already have the heater. Replacing the supply line is not an option as it would require digging up my yard, destroying me deck, etc which we are not looking to do.

I'm looking for recommendations on heaters that can operate on 4" wc pressure that I have consistently. Due to the features of the LT Laars unit I have, it will not.

I'll check the screen issue, but in the end, I may need a different heater. Call it poor design of the system on the builders part, restrictive design constraints by the heater mfr, whatever. In any event, I have just under 5" sc pressure to work with and need to find a way to make it work. Otherwise I have a $2500 boat anchor waiting to happen.
