Not sure if 100c would work since they are mostly plastic, but I do have a
similar sized metal one that is significantly stronger....uses 110v...
Has anyone considered propane? My uncle out in Indiana makes his own
roasters...typically trailer deals for a quarter hog or more...The last one
he made I believe he used the burners from a couple old furnaces...he did
manage to max out what the tank was able to put out...had to turn off one
of the burners to get the pressure back up.
Anyways, just a thought though for all I know the stuff is probably
flammable
