摘要

The arrangement has a pot-type housing (22) with a base region and a wall region. A base projection arrangement (42) with multiple of rib-shaped base projections (60) that extend radially from inwards to outwards with respect a longitudinal middle axis of the housing is provided at a side (40), which is turned towards interior of the housing, of the base region. The projections are connected with each other in a radial inner region. The projections comprise sectors (64) with an angle extension of 90 degrees. An independent claim is also included for a heating device comprising a burner region.
