      If You Don't Know

      The foot of tubing or heat loss how would you size a pump? There is no magic chart. What seems to be the problem that you are experiencing to make you think there is a problem?

      Did this just happen or has it always been an issue?

      pump sizing

      Suspect this problem on 2nd floor has always been there, the bldg goes through 1 mtc. man a year. No past record keeping. Have found some good info through watts , taco and Cal Steam, today.  thanks all !
