aquapex for heating
BOONE Member Posts: 1
Found out that my radiant heating system has aquapex that is non barrier. Does anybody know have a solution? Can you install a 95% boiler with stainless/ no metal and be fine? Or is there another fix? Thanks.
The best way is to isolate the tubing from the boiler system by using a flat plate heat exchanger. An additional circulator (stainless or bronze), expansion tank and air eliminator is needed for this. Consider installing a strainer on the inlet of the plate hx.
Whether you decide to add a plate hx or not a system cleaner should be used to remove any residue in the PEX tubing.

depends on the boiler
Triangle Tube says you can use open oxygen systems with their boilers. the 110 solo an excellence have cast iron pumps built in that need to be replaced, but otherwise, no problem. make sure you don't use cast iron outside the boiler.Rob Brown

Where does it say Triangle Tube boilers can be directly connected to an open system? Here's what I found from their online documents:
Do not install the Excellence water heater on
any application if the boiler piping contains
non-oxygen barrier tubing or if the boiler
piping is considered an “open system”.
Exposing the outer tank of the Excellence
water heater to oxygen contamination will
lead to premature tank failure and denial of
Consider protecting your investment
The high cost of any appliance should cause pause when knowing the damaging effects this tubing can pose to all system components. Just because the hx is stainless does not protect other components (flow/temp sensors etc.) of these high buck boilers.
Isolation from the system is the safest way to prolong the life of a new boiler in this situation, not the least expensive now but could definitely save you a lot of money & headaches later. my two cents...again."If you don't like change, your going to like irrelevance even less"0
