    gravity to pumped

    It started as a gravity hot water system (1899) and was converted to pumped about 20 years ago. The boiler  is about 25 years old and was converted at some point from oil to gas.

    1 cph and that is usually what my experience has been. If you have O.D.reset, you might try 2 cph.



    A high mass system has a "flywheel" effect. Takes a lot to get it going and it wants to keep going after the ignition is turned off.
