I just put mine in a keg for conditioning yesterday afternoon. Good thing too since my ferm chamber heater burned up overnight! Damage was limited to the chamber since it was constructed of all fire retardant materials and well sealed so no O2 was available to feed the fire. The only real loss were two secondary carboys of beer- a Columbus IPA & a California Common.
HOLY SH!T. glad no one was hurt and your house is fine. Sorry for your losses.
