A fire pit is an open burning bowl, whereas a chiminea is built with a chimney. The outdoor fireplace products on the market that have mesh wrap-arounds, multi openings or bowl designs should be considered fire pits.There are many fire pits incorrectly advertised as chimineas, but they are not chimineas.A chiminea will have a flue or chimney that drafts properly much like an indoor fireplace. The drafting on a chiminea naturally brings fresh air into the fire and directs smoke up, away from guests. cast iron or cast aluminum chiminea is always going to be a better investment that will last many years after a clay one falls apart. The majority of clay fireplaces have a life span of less then a year before needing to be replaced. We recommend metal chimineas to anyone considering purchasing a chiminea.
