The known heat exchangers according to the preamble of the main claim, which are usually, in particular for floating = · baths, free standing! are used in the field, have an unsatisfactory efficiency. An improvement could be achieved on the model of large-scale systems by extending the heating gas flues and the like Expansion of the water channels arranged in the hot gas flues Means for intensifying the hot gas flue, for example by using a higher chimney or a fan.

The invention is based on the object of improving the heat transfer and thus the efficiency with a compact construction.

According to the invention, this object has been achieved by that the shaft is provided with a roof-shaped upper part, the walls or roof surfaces of which carry water Contain or form channels. With this measure, not only can a decisive improvement in the Achieve heat transfer, the roof-shaped design also enables a particularly compact, low construction. It also has the advantage that the operation of the hot water generator is largely independent of the weather close.

The roof-shaped upper part can be created in that the upper part of the shaft itself tapers like a roof or that the upper shaft opening at a distance from a roof-like deflecting the rising heating gas hood is covered. These two possibilities are preferably combined with one another; it arises from it the advantageous possibility of increasing the heat transfer through the roof surfaces to a substantial extent To extend part of the shaft height and to cover the shaft opening to be relatively compact, so that it does not protrude beyond the base of the shaft.

Further features of the invention can be found in the following description of an exemplary embodiment, as illustrated in the accompanying drawing. In it is

Hot water generator according to the invention,

of Fig. 2.

The hot water generator shown, designed as a free-standing device and in particular for the operation of Swimming pools is intended, consists essentially of a shaft 1 with shaft base 1a and roof-like Upper shaft part 1b. The shaft has a more or less elongated rectangular base that extends below both long sides with air inlet slots 2.2 to the In the lower shaft part arranged heating gas burners 3 and above with over its entire length extending, also slot-shaped shaft opening 4 is provided and contains various channels around which the heating gas flows or which are coated and which carry the water to be heated.

Inside the shaft 1 there are heating gas on all sides surrounded by water channels 5, hereinafter referred to as inner channels designated. The two outer longitudinal walls of the Shafts are also designed as water channels. Furthermore, the upper shaft opening 4 is also of one formed as a water-carrying channel 7 hood 8 arched, the edges 9,9 with the outer sides 11,11 the longitudinal walls of the shaft form downwardly directed outlet slots 10,10.

The shaft part is tapered towards the shaft opening 4 and thus has the shape of a double roof.

The spatially parallel water channels 5, 6 and 7 are at their two ends on collecting chambers 12, 12 connected, which form the end faces of the shaft. The end of the hood 8 also has end walls completed as the water end chambers 13 in the collecting chambers 12 are included.

The inner channels 5 have polygonal cross-sectional profiles. Their wall sections 16 adjacent to the smooth, non-wavy inner shaft wall 14 extend essentially parallel to the shaft inner wall 14 and form with it accordingly from the lower to the upper shaft end smoothly rising outer heating gas flues 15. The adjacent wall sections 18 of the inner ducts 5 also run essentially parallel to one another, but their inclination to the vertical changes at the corners or edges of the water channels according to the different inclinations of the inner wall sections 18 such that these wall sections 18 inner heating gas flues 17 with wavy or zigzag shapes Form course.

The water-carrying channels 5, 6, 7, which run spatially parallel to one another, are attached to the front collecting chambers 12 not with their respective aquifer
