Bad luck on the busted boiler. You will probably need to buy a whole
engine to get a boiler. Keep in mind that any KJ Miller you buy has
a chance the boiler base is cracked even though the carbon blocks may
be whole...or both may be broken. No doubt these boilers are problematic.
Very problematic. Search you tube - I saw a video about this several
years ago.

came without a boiler but the other 4 had good carbon blocks but three had
cracked bases. The only fix I've seen is to replace the base and use
other short cartridge heaters to power it. The carbon block concept
is elegant and automatically stops the power when the water level gets
too low. Unfortunately, the implementation of this idea is too slick for
its own good.
Good Luck,
