Definitions
- the invention is based on a hot water supply system according to the genus of the main claim.
- this genus DE 34 31 555 A1
- the heater of which a a heating water circuit fed secondary heat exchanger for Has hot water heating the flow circuit for Circulation water through a storage tank, which is also from Heating water circuit fed and at least on Maintenance temperature of the circulation water is maintained.
- the frequency at which the heater is switched on can Times of low heating and hot water heating requirements be reduced.
- the arrangement according to the invention with the features of The main claim has the advantage that the heater in the pure Circulation mode is only switched on when the Temperature of the heat exchanger to the maintenance temperature of the circulation water has dropped. This will also without heating and installing a store Switch-on frequency of the heater in otherwise low heat consumption times and on the actual need to maintain the Circulation water temperature turned off.
- the heating temperature of the heat exchanger detecting temperature sensor can be provided.
- this can be done between the heat exchanger and the Hot water connection of the heater a sensor for detection the hot water or tap water temperature may be provided.
- the amount of circulation water can be simple and reliable by arranging a water flow limiter in the Circulation line to one below the Inlet water quantity may be limited. Of the different water flow between the circulation and the normal amount of tap water can be advantageous by a between the cold water connection and the heat exchanger arranged water quantity sensor can be determined.
- the system shown has a heater 10 with a Gas burner 12, the combined heat exchanger 14 for Heating water and domestic water heated.
- the as Lamella block trained heat exchanger 14 is penetrated from a heating water pipe, whose Lead strand 16 with a connection 18 for one through the Symbol 20 shown heating network is connected. Whose the other end is connected to the heater 10 via a connection 22 a return line 24 connected via a circulation pump 25 leads to the heating water inlet of the heat exchanger 14.
- the fin block of the heat exchanger 14 is also from Pipes carrying industrial water that passes through a Cold water line 26 with a cold water connection 28 and over a hot water line 30 with a hot water connection 32 are connected.
- a Hot water connection 32 At the hot water connection 32 is one Line 34 connected, which leads to taps 36.
- a water quantity limiter 38 built in, to the specified maximum value of the pro Time unit flowing through the tap water quantity is set.
- a temperature sensor 40 is on the hot water line 30 provided that with the not shown Control device of the device is connected, which u. a. controls the temperature of the tap water flowing through or regulates.
- the system shown also has a flow circuit for Circulation water, which via a circulation line 42nd leads.
- This has an inner wiring harness 44, the a connection 46 branches off from the cold water line 26 and over a water flow limiter 48 to a circulation connection 50 of the device leads.
- the circulation line goes from there 42 via a backflow preventer 52 and a Circulation pump 54 continues to tap 36 where it starts the line 34 leading into the tap water accordingly branched is connected.
- the flow circuit for the circulation water closes over the section of the tap water pipe that from the connection 46 to the hot water connection 32 and from there to the Tap 36 leads.
- This section is between the Water flow limiter 38 and the heat exchanger 14 a Turbine 56 installed as a water quantity sensor.
- the Water flow limiter 48 is set so that the Circulation water volume less than the switch-on water volume is where the heater 10 is used for heating of the tapping water provided goes into operation.
- a Water quantity sensor are used, with the help of the Circulation water volume can be controlled or limited. Due to legal regulations it is e.g. prescribed that the circulation water for disposal the risk of legionella has a minimum temperature.
- the circulation pump 54 can continue by known means such. B. by a Timer, be controlled.
- the water quantity sensor 56 recognizes the different Water flow between the circulation and the normal tap water withdrawal. If the temperature at Heat exchanger 14 below one of the circulation temperature assigned value has dropped, the gas burner 12 with the one for heating the circulation water to one specified setpoint or to the maintenance temperature required power put into operation. To capture the Temperature at the heat exchanger 14 can accordingly trained temperature sensor 40 serve or a additional temperature sensor directly on the heat exchanger 14 may be provided. If at the same time a warm request from the heating network, the Circulation water heating takes priority. But when when heat is requested from the heating network, the temperature of the Heat exchanger is above the setpoint, a Parallel operation of circulation water heating and Heating water heating can be provided.
