    pressurized tanks

    are tough to build in any shape but round. The jacket may be square like Ergomax, Buderus, Viessmann, the older Triangle horizontal tanks and a few others.

    I did see some clever oval tanks at Intersolar a few years back, designed to fit thru doorways. ASME a requirement probably?

    By solar tank do you mean with coils inside? I think Niles builds custom tanks with your choice of HX hanging inside.

    Just storage/ No exchange


    These will be for storage, no coils needed.

    I really don't care if it is round or square as long as I can get through the doorway. The width of the doorway to the mechanical room is 35". It is going to be hard enough getting 3 round tanks through the door!LOL!

    Thanks for the info.
  • Non-pressurized Tanks

    You wouldn't want to make a non-pressurized tank for storage?

    Thanks, Bob Gagnon
