Fig.2 (section AB of Fig.1) a section through the lower part of the lamellar tube with the Sleeve in opposite F i g. 1 larger scale. Arrangement for instantaneous water heaters, especially one with oval cross-section, with fins 2 More for hot water circulation heating systems, 5 set flow tubes 1 provided lamellar block with a heat sensor, which closes the heating shaft H, not shown, in a connection with a flow tube in the gas-heated water heater above. The lamellar block lying to the heating gas flow is standing and warming water flows through the flow tube 1 is tightly enclosed by a wall, one in the direction of the arrow. Several of these flow tubes lie next to one another on the lamellar block, preventing water contact with the heat sensor, and are connected to one another over the entire length and most of the other by elbow 3. At the deepest of its circumference with the wall of the water supply point of the flow tube 1, a metal sleeve 4 which is directly thermally sealed at one end is soldered.

Before installation cL: r metal sleeve 4, this is attached to your The main patent 1 301 035 relates to an arrangement underside pressed in, so that some one behind the other with continuous flow heaters, especially for warm-lying warts 4 '.

B. as a sensor via an air gap 7 is possible.
The wall formed by the sleeve is thereby assumed that the temperature limiter has an influence on the temperature of the metal parts of the lamellas - a closed heating system of a tub block - as well as on the temperature of the water heating system at a flow temperature. It has been shown, however, that the temperature should switch off from 110 ° C, so the heat temperature that the sleeve wall under these influences sensor 6, which also assumes from the higher temperature, is not uniform, but that in the 40 Door of the lamellar block or flow tube 1 affects the sleeve wall a temperature gradient after which the flow occurs to a shutdown temperature of 128 ° C water-facing side. Come in from there. If the water heater is temporarily never achieved for technical reasons with greatly reduced, z. B. half power that the inserted heat sensor ben everywhere, so the temperature of the flow tube 1 drops evenly on the sleeve wall, the 45 depends more than that of the water. From the side of the temperature that the heat sensor assumes, from the flow tube 1, the heat sensor 6 is now randomly located, which the heat sensor is supplied within the heat. The switch-off temperature of the sleeve is just taking. The temperature sensor therefore only reaches 128 ° C with one The invention is based on the problem of this higher water temperature than was previously provided with 110 ⁰ C difficulties in the arrangement after the main. The heat sensor 6 would be eliminated in ungünpatent. The invention consists in the fact that the metal sleeve 4 rests at the bottom, so in the case of an arrangement according to the main patent of the war, the water temperature rises to 122 ° C., as was determined by measurements only on that part of the inner wall Heat is applied, the outside of which the flow tube sensor 6 is facing its shutdown temperature of 128 ° C. It is achieved in that the submitter submits. This means that the shutdown by the flow of the water temperature on the heat sensor is opti- temperature limiter instead of HO ⁰ C only once, while the influence of the lamellar block temperature 12 ° C higher flow temperature of 122 ° C is weakened, but at least still so switches. If, however, the heat sensor 6 - as above remains large in order to describe the heat sensor in the event of overheating - is on top, ie on the water to cause the heating power to be switched off. 60 facing side on the metal sleeve 4, so reached. An embodiment of the invention is shown in it its shutdown temperature of 128 ° C in the drawing and described below a water temperature of 114 to 115 ° C, so that ben. So it only shows an overtemperature at half the heating power F i g. 1 shows a longitudinal section through a lamellar tube at 5 ^° C. instead of 12 ^° C. with a soldered-in thermostat sleeve 65 must.
