    The potential code problem with the just plug it in idea is that a boiler is usually classed as a fixed appliance -- and in some jurisdictions the AHJ will insist on that being hard wired on an independent circuit with an appropriate emergency switch (or switches). It varies. You might be able to get away with having any plug within reach of the cord wired on that independent circuit, with the required emergency shutoff switches. You might not.

    Any competent electrician would know the local codes and, if it is permitted, just about do the job in his or her sleep.

    Codes are funny. Physical disconnect sounds safer than a switch? This thread reminds me of how in the good old days steam was considered THE reliable source of power for industry. Fired with coal of course. After switch to dual fuels....

    We never use China fittings, nipples, pipe or controls on our work. Never did and never will. Even our electrical components are absolutely domestic.

    But a backup battery that customers supply and plug in? That's on them.
