Abstract
The invention relates to a heating device comprising at least one heat exchanger that spirals helically around a spiral axis, is traversed by a heating medium and is configured as a flat tube comprising ends of the spiral on the feed flow and return flow sides and heating medium connections, said heat exchanger defining a corresponding spiral-shaped flow opening. A cap-type sealing housing is attached in a fluid-tight manner to at least one end of the spiral and the heating medium connection is situated on the housing. At least one end of the spiral is obliquely truncated in relation to the spiral axis and the end of the sealing housing on the spiral side has a corresponding inverse oblique configuration. Preferably, the heating medium connection on the cap-type sealing housing runs in the direction of the spiral axis.
