    Are you putting in a high-pressure boiler?

    That 3/4" supply line isn't going to work with a low-pressure boiler.
    Retired and loving it.

    Steam Kettle

    You should be able to get the pounds per hour and pressure from the manufacturer and size piping and boilers as needed. The only kettles I have done required small amounts of steam due to the small steam space around the kettle. It has been a while but it seems that the kettle run around 10 psi. You obviosly must stay within the design limits of the shell.
