Excellent advise ,I have done exactly the same thing. The call backs I especially do not like are the ones after hours, you have to wait until the next morning ,so you spend all night thinking about what could be wrong. You cannot sleep, so you spend the time reading every book you have trying to find a clue to the problem, no fun.All.the best Jack

Ghost flow is a common occurrence but usually not a problem unless there is an extreme imbalance in the zone btu requirements. Recently I noticed a indirect hot water heater causing ghost flow, the couple didn’t use enough hot water to cause any over heat problem summer or winter. The piping to the indirect hot water heater went down so it did not overheat.

if the basement zone valve was situated on the return line before the connection to the system return would you still have had the same problem?

Never mind, I see the error of my thought.

ha ha. I knew old timers who celebrated invention of circulating pump that would make HHW so simple. Especially compared to steam. HeatingHelp shows nothing is simple.

What I noticed is that circulator is on the return so it's not pumping away, or did I miss something?
