Hi Heatpro, Awhile back you helped me on purge system and expansion tank pressure in the boiler. On the site you sent me to, it said that divide the height of highest radiant floor heat divide by 2 and that would be your expansion tank pressure, and add 4 psi to that for your cold water static pressure. I just read on the taco site that the cold water static pressure should equal the expansion tank pressure. That dont seem to make sense. Think someone just typed in wrong info?
