Dennis Senesac came by to investigate why, when we turn on the thermostat that supposedly controls radiant floor heating in the study, laundry, and master bathroom, the floor heat for the master bedroom, shop, shop lavatory, and storage room also comes on.  The problem seems to have been that, because we’ve never turned on the radiant floor heat anywhere other than the study, the valves controlling flow in those other lines had never seated closed, allowing “ghost flow” to happen.
