Sizing Compression Tanks

Neil Fay
Neil Fay Member Posts: 6
I have a failed steel 30 gallon (60" X 12") compression tank. The system was originally gravity circulation, now converted to forced, with much of the distribution piping reduced (substantially).

How do I determine the correct size of the replacement tank?

    Time ?

    Take the time to acurately estimate the contents of the system in gallons, then look at the manufactures of compression tanks to determine the best tank for the job. A second cheap way would be to buy a smaller tank say a size 12 and be perpared to add another if the relief valve leaks upon fireing up the system. the 60" one you have now is very big comparatively.

    The easy way...

    If the 30 gallon tank worked fine for you, and you've actually decreased the volume of the system, then any tank manufacturers #30 tank will work.
