Abstract
The invention is concerned with a gas hot water heater intended for installation in a wall and including a combustion chamber from which are guided heating gas tubings within a water-carrying housing. The housing is provided with connections for forward and rearward flow of water and an exhaust gas collecting chamber provided with connections for exhaust gas and condensate discharge. In the practice of the invention, a heating gas tubing passing from top to bottom through the water-carrying flat box-type housing is in the form of at least one pocket extending parallel to a broad rear wall of the housing. A water-cooled combustion chamber, disposed in an upper portion of the housing substantially corresponds, in plan view, to a flat rectangular cross-section of the housing. A burner insert opening of the combustion chamber is provided within or approximately within the plane of a front wall having a width corresponding to, and extending parallel with, a rear wall. This will result in an extremely flat design of the hot water heater involving low manufacturing efforts and permitting an automated manufacture.
