Anybody seeing problems with this increase? seems it is a bit above what the boiler and indirect tank manufacturers reccomend.
A couple specs from HTP for tanks and boilers attached.

    I wouldn't be concerned. I run from 9-10. I think the manufacturers are a little conservative on the target PH because they don't want frothing/surging that could result in return service calls for installers/service companies. But if you watch your boiler I think you'll see it's fine below nine.

    edit: mine's a steam boiler...sorry I get a little steam tunnel vision. Others will comment on other applications :)
