I run triangle tube boilers is it ok to use RO water in the system? I have floor heat and fin pipe.

    Yes -- but you will want some sort of corrosion inhibitor and pH buffer in the system. RO is pretty "hungry" (but not as aggressive as DI)

    May be time to send a water sample to a lab and see what is the best direction to go as far as treatment/adding chemicals.

    There was a batch of short life heat exchangers on the market a few years back, weld issues. Contact the rep to see if yours are in the date code range.
