ABSTRACT:
This gas-powered apparatus comprises a substantially cylindrical combustion chamber having an inlet for the combustion air connected to the outside and an upper outlet connected to a burned gas flue. A tank is arranged around the combustion chamber and defines therewith an interspace, so that the water in the tank can be heated substantially by radiation. The interspace is downwardly connected to a duct having an opening for a fan sucking air from the enclosed space through the interspace and returning it to the enclosed space.
