Runtal UF-2 Radiator Rusting from inside out
I have a radiant in floor PEX heating setup on my main floor, however the bonehead installer (who quickly went out of business) installed non-oxygen barrier PEX, so my system has been plagued with corrosion issues over the years. I had to replace my boiler to deal with the rust as well as oxygen removing components in the plumbing. However, the installer that fixed me up said eventually my Runtal Baseboards (in the basement) would “pit” out with rust from within, since they are not meant to be used with oxygen rich water.
Well, the day has come (see photo link below). So I’m starting to investigate options to replacement. It looks like from brief searching (nothing thorough yet), Slant Fin may be an option. Some literature I read on the Fine Line series said it had “rust resistant” from galvanized enclosures, but I’m not certain that isn’t just the cover. Anyhow, looking for any leads or advice on options. Thanks!photo of rust & radiator
