Definitions
- the invention relates to a method for enabling the essentially instant tapping of hot domestic water in a combination heater having an intermittent burner and a primary heat exchanger for supplying heating elements operated with hot water and for supplying at least one hot water tap via a secondary heat exchanger, the primary circuit of which is optional can be connected to a heating circuit containing the radiator (s) and the primary heat exchanger and provided with a circulation pump.
- the aim of the invention is to provide a method of the type mentioned at the outset, which makes it possible to provide hot water immediately, even during the standstill phases of the burner, without any significant additional design effort.
- this is achieved by maintaining the temperature in the primary circuit of the secondary heat exchanger during the breaks in the burner at least temporarily maintaining a flow of the heated water through the circulation pump, which is only conducted via the primary heat exchanger and the primary circuit of the secondary heat exchanger.
- the method according to the invention also has the advantage that the radiation losses in the secondary heat exchanger are covered by the heat loss from the circulation pump, which is why Arrangement of a separate radiator in the secondary heat exchanger can be dispensed with, or the commissioning of the main burner with the associated additional losses becomes superfluous.
- Another object of the invention is a device for carrying out the method according to the invention with a primary heat exchanger acted upon by a burner, to which a secondary heat exchanger for heating the process water with its primary circuit and a flow line leading to the radiator (s) and the outlet are connected on the outlet side of the primary circuit of the secondary heat exchanger via a 3-way valve, to which a return line coming from the radiator (s) or a flow line leading to the radiator (s) is connected, with one to the suction side of the circulation pump, which is hydraulically connected in series with the primary heat exchanger lies, leading line is connected, with a depending on the room temperature and the flow temperature and the flow conditions in the secondary circuit of the secondary heat exchanger control for the burner, the circulation pump and the 3-way valve is provided beat.
- the circulation pump can be controlled independently of the burner, wherein a sensor monitoring the temperature in the primary circuit of the secondary heat exchanger or, if appropriate, a sensor monitoring the temperature in the secondary circuit of the secondary heat exchanger, influencing the control of the circulation pump in such a way that when the temperature falls below the temperature defined in the program of a controller, the pump is started until it is reached again becomes.
- a buffer store is connected directly upstream or downstream of the secondary circuit of the secondary heat exchanger and the secondary heat exchanger and the buffer store are accommodated in a common, insulated housing.
- the device has a burner 1, which can be supplied with gas via a solenoid valve 2 and acts on a primary heat exchanger 3.
- This primary heat exchanger 3 is connected on the output side to a flow line 4 leading to radiators (not shown) and to the input of the primary circuit 5 of a secondary heat exchanger 6.
- the return line 7 coming from the radiators is connected to a 3-way valve 8 to which the return line 9 coming from the primary circuit of the secondary heat exchanger 6 and the suction line 10, 9 of the circulation pump 11 are connected.
- the primary heat exchanger 3 is connected to the circulation pump 11.
- the secondary circuit 12 of the secondary heat exchanger 6 is connected on the input side via a flow switch 13 Cold water connection 14 and connected on the output side to a buffer store 15 which is connected upstream of a hot water tap 16.
- a temperature sensor 17 for detecting the flow temperature which is connected to the control unit 18, which is further connected to a warm start switch 19 and the flow switch 13 as well as the solenoid valve 2 controlling the gas supply to the burner 1 and with the drive of the 3- Directional control valve 8 and the circulation pump 11 is connected.
- a temperature sensor which is also connected to the control 18, can be arranged in the secondary circuit 12 of the secondary heat exchanger 6 and detects the temperature in the secondary circuit 12.
- the control 18 switches the 3-way valve 8 into the same position as when the process water is drawn off, so that a water circuit is formed via the secondary heat exchanger 6, the circulation pump 11 being kept in operation at times. This ensures that the heat generated by the operation of the circulation pump 11 is largely introduced into the water flowing through the primary circuit 5 of the secondary heat exchanger 6 and the radiation losses of the secondary heat exchanger 6 are covered.
- the circulation pump 11 is kept out of operation via the control unit 18 until a further increase in the temperature level in the primary circuit 5 is necessary due to heat losses.
- this is arranged together with the buffer store 15 in a housing 20 which is lined with heat-insulating material.
