Problems solved by technology

Potentially incorrect measurement of the discharged liquid in the event of incorrect fittings
It is also possible that the flow sensor does not output any signal at all, i.e. it cannot be determined whether liquid has been discharged

Embodiment Construction

[0034] in figure 1 A straight-through heater 1 with a heat exchanger 2 is shown in the figure. The heat exchanger 2 has a domestic water inlet 21 and a domestic water outlet 22. The thermal energy generated in the heat source 52 is sent to the heat exchanger 2 via a secondary circuit 5. Here, the transfer of thermal energy from the heat source 52 to the heat exchanger 2 takes place by means of liquid, especially water, which is driven by a pump 51.

[0035] When properly installed, a cold water pipe 31 is provided on the domestic water inlet 21 and a hot water pipe 32 is provided on the domestic water outlet 22. The flow direction through the heat exchanger 2 then proceeds from the cold water line 31 to the hot water line 32. Here, the heat energy is transferred to the liquid in the heat exchanger 2, that is, the liquid is heated, and the liquid is heated and discharged on the hot water pipe 32. It is assumed below that water is used as the liquid, but other liquids are also co...

Abstract

The invention relates to a through heater (1) and a method for operating a through heater with a heat exchanger (2) for heating a liquid flowing through, the through heater The type heater has a domestic water inlet (21) for connecting the cold water pipeline (31) and a domestic water outlet (22) for connecting the hot water pipeline (32), wherein, there is a control or Control device (4) for regulating the external temperature of the discharged liquid. To enable operation of the through heater even when the cold water line (31) is connected to the domestic water outlet (22) and the hot water line (32) is connected to the domestic water inlet (21), the (21) arranges a temperature sensor (6). Depending on the direction of flow through the heat exchanger ( 2 ), the actual temperature of the liquid is adjusted to a predetermined target temperature.

Description

Technical field [0001] The present invention relates to a straight-through heater having a heat exchanger for heating a liquid flowing through it. The straight-through heater has a domestic water inlet for connecting a cold water pipeline and a hot water pipe The domestic water outlet of the road is provided with a control device for controlling or adjusting the temperature of the liquid. [0002] The invention also relates to a method for operating such a straight-through heater with a heat exchanger for heating a through-flow liquid. Background technique [0003] The straight-through heater is used for heating domestic water, for example. Here, the water is sent to the straight-through heater through the cold water pipe, is heated by the heat exchanger inside the straight-through heater, and is discharged through the hot water pipe. The heat exchanger can be heated directly or via a secondary circuit. The term domestic water is generally understood and includes drinking water ...
