    You’d need a UPS with sufficient capacity to power the boiler, pumps and any ancillary controls.

    calculate how much power is required to run the boiler and any pumps required, plus the inverter itself.  then how long you want to run off if the battery, size the batteries accordingly

    Bosch boilers use 2amps or less. A little more than a modern gaming PC.
