I Inherited a bldg with rad floor heating (PEX Tubing)  any one know of any pipe T.E.L. sizing charts that I could use to to verify If my ft/head at my pump is adequate.  There are no mech prints.  I have 27 rooms, dont knowhow much tubing is under floor.

    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?

    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 !
