Description

  The present invention relates to a heating system that performs heating by operating a heater such as an air conditioner or a heating mat using hot water supplied from a heat source device, for example.

  For example, as shown in FIG. 6, the hot water produced by the heat source device 40 is supplied to one or more (generally plural) hot water terminals 9 (here, 9a, 9b) via a pipe and connected to the hot water terminal 9. There is used a heating system that supplies warm water to a heating machine such as an air conditioner 47 or a mobile fan convector 48 to perform heating. The hot water terminals 9 are provided, for example, in a room such as a living room as needed, and hot water (hot water) as high as 80 ° C. is supplied from the heat source device 40 to each hot water terminal 9.

  Some heating systems have a function of changing the temperature of the hot water to be supplied to 80 ° C. or 60 ° C. Even in this type of heating system, the plurality of hot water terminals 9 all have the same temperature. In addition, it is preferentially determined to supply hot water at 80 ° C. In other words, if an air conditioner 47 or the like that needs to be supplied with hot water at 80 ° C. is connected to one of the plurality of hot water terminals 9, 80 ° C. hot water is supplied from the heat source device 40 correspondingly. It is supplied to all the hot water terminals 9.

  On-off valves (not shown) are built in heaters such as the air conditioner 47 and the mobile fan convector 48. The on / off valves turn on / off the supply of hot water to the heaters to control the heat radiation amount of the heaters. Heating is performed at the heating set temperature.

  There are various types of heaters. A typical example of a heater that operates by supplying hot water is a heating mat (hot water mat). In general, a heating mat is optimally operated to operate in an optimal state. The hot water temperature is 60 ° C. In addition, although the heating mat (heating panel) corresponding to high temperature warm water supply is also considered in some, this heating panel is not generally used (for example, refer patent document 1).

  By the way, since the demand for floor heating has increased in recent years, for example, in the heating system as shown in FIG. 6, floor heating is performed by connecting a heating mat to the hot water terminal 9 instead of the mobile fan convector 48 or the like. Can be considered. Thus, if floor heating is performed using the existing hot water terminal 9, it is considered that the cost can be reduced as compared with the case where a new heating system is formed for floor heating.

  However, as described above, the heating mat generally used has an optimal operating hot water temperature of 60 ° C. for operating in an optimal state, and is different from the hot water temperature supplied from the heat source unit 40 to the hot water terminal 9. For example, when a heating mat having an optimum operating hot water temperature of 60 ° C. is connected to the hot water terminal 9 of the heating system as shown in FIG. 6, the temperature of the hot water supplied from the heat source unit 40 to the heating mat and the optimum operation of the heating mat The hot water temperature will be different.

  Further, since the heating mat is not provided with an on / off valve that is built in a heater such as the air conditioner 47, the supply of hot water to the heating mat cannot be turned on / off.

  Therefore, even if the heating mat is simply connected to the existing hot water terminal 9, the temperature unevenness of the heating mat becomes large, and the heating mat cannot be operated satisfactorily at the heating set temperature to perform comfortable floor heating. For this reason, it has been difficult to form a heating system using the existing hot water terminal 9.

  In addition, although the heating panel of the said proposal example was considered corresponding to high temperature hot water supply, it does not have an on-off valve of hot water supply, and this proposal example is hot water supplied to the pipe line of a heating panel. The flow rate adjusting valve is provided in the external piping of the heating panel to adjust the heating temperature, and therefore cannot be applied to the existing heating system as shown in FIG. Moreover, the heating panel of a proposal example also has the problem that it is not easy to eliminate the temperature nonuniformity in a panel.

  The present invention has been made in order to solve the above-mentioned problems, and its purpose is to reduce the cost by using, for example, an existing system, and to operate a heater such as a heating mat in an optimal state. An object of the present invention is to provide a heating system that can perform comfortable heating by operating a heater well even when hot water having a temperature higher than the above temperature is supplied from a heat source device.

  In order to achieve the above object, the present invention has the following configuration as means for solving the problems. That is, 1st invention is a heating system which heats by supplying warm water to one or more warm water terminals via piping from a heat source machine, and supplying the warm water to a heater connected to each warm water terminal A hot water temperature non-matching heater in which an optimal operating hot water temperature for operating the heater in an optimal state is different from a temperature of the hot water supplied from the heat source device in a low temperature direction is one of the hot water terminals. Connected to the hot water terminal, a hot water temperature detecting means for detecting the temperature of the hot water supplied to the hot water terminal in the vicinity of the hot water terminal to which the warm water temperature incompatible heater is connected, and the hot water terminal A hot water supply on / off valve that performs on / off operation of hot water supply to a corresponding non-conforming hot water temperature heater, and detection that detects the timing of on / off operation of the hot water supply on / off valve by the hot water temperature detecting means And a means for solving the problems with the arrangement having a valve on-off timing control means for controlling in accordance with the timing control information defined in advance corresponding to the time to on the basis of the detection temperature and the set heating temperature of the heater.

  Further, in the second invention, in addition to the configuration of the first invention described above, the valve on / off timing control means is in a period from the start of operation of the hot water temperature incompatible heater until a predetermined on / off timing control start condition is satisfied. The hot water supply on / off valve is turned on, and when it is determined that the on / off timing control start condition is satisfied, the operation timing control for alternately repeating the on / off operation of the hot water supply on / off valve is started. .

  Further, in the third invention, in addition to the configuration of the second invention, the valve on / off timing control means starts the on / off timing control when a predetermined set waiting time elapses from the start of operation of the hot water temperature incompatible heater. It is determined that the condition is satisfied, and the operation timing control for alternately repeating the ON operation and the OFF operation of the hot water supply ON / OFF valve is started.

  Furthermore, the fourth invention has heating temperature detection means for detecting the heating temperature of the heater in addition to the configuration of the second or third invention, and the valve on / off timing control means is controlled by the heating temperature detection means. When the detected temperature reaches a value obtained by subtracting a predetermined reference temperature for determination from the preset heating temperature of the heater, it is determined that the on / off timing control start condition is satisfied, and the hot water supply on / off valve is turned on / off. It is characterized in that operation timing control that alternately repeats the operation is started.

  Furthermore, in addition to the structure of any one of the first to fourth inventions, the fifth invention is characterized in that at least one of the heaters includes a plate-like mat portion provided with a pipe through which hot water passes, A heating mat having a header connected to the mat portion to connect the pipe and the hot water terminal in communication with each other.

  According to the present invention, at least one of the hot water terminals for supplying hot water from the heat source machine has an optimum operating hot water temperature for operating the heater in an optimal state, the temperature of the hot water supplied from the heat source machine and the low temperature. Different hot water temperature incompatible heaters are connected in different directions, and in the vicinity of the hot water terminal, hot water temperature detecting means for detecting the temperature of the hot water supplied to the hot water terminal, and the hot water temperature corresponding from the hot water terminal A hot water supply on / off valve for performing on / off operation of hot water supply to the nonconforming heater is provided, and the valve on / off timing control means is based on the detected temperature detected by the hot water temperature detecting means and the heating set temperature of the heater. The timing of the on / off operation of the hot water supply on / off valve is controlled in accordance with timing control information determined in advance.

  Therefore, even if a hot water temperature non-compliant heater such as a heating mat with an optimum operating hot water temperature of 60 ° C. is connected to a hot water terminal of an existing heating system that supplies hot water of high temperature such as 80 ° C. from a heat source machine, the valve is turned on / off. If the hot water supply is controlled by the on / off operation control of the hot water supply on / off valve by the timing control means, it is possible to realize a heating system that can operate the warm water temperature incompatible heater well and perform comfortable heating. Moreover, since the existing heating system can be used, the cost of system construction can be reduced.

  Further, in the present invention, the valve on / off timing control means turns on the hot water supply on / off valve from the start of operation of the hot water temperature incompatible heater until a predetermined on / off timing control start condition is satisfied, and the on / off timing control According to the configuration that starts the operation timing control that alternately repeats the ON operation and the OFF operation of the hot water supply ON / OFF valve when it is determined that the start condition is satisfied, the ON / OFF timing control starts from the start of the operation of the hot water temperature incompatible heater Until the condition is satisfied, the hot water supply on / off valve is turned on to quickly increase the temperature of the hot water temperature incompatible heater, and then the hot water supply on / off valve can be turned on / off to perform heating comfortably. .

  Further, in the present invention, the valve on / off timing control means turns on the hot water supply on / off valve until a preset waiting time elapses from the start of operation of the hot water temperature incompatible heater, and when the set waiting time has elapsed. According to the configuration in which it is determined that the on / off timing control start condition is satisfied and the operation timing control for alternately repeating the on / off operation of the hot water supply on / off valve is started, the warm water temperature incompatible heater is set during the set standby time. The temperature can be raised quickly, and then the hot water supply on / off valve can be turned on and off to perform heating comfortably.

  Further, in the present invention, there is provided a heating temperature detecting means for detecting the heating temperature of the heater, and the valve on / off timing control means has a detection temperature detected by the heating temperature detecting means determined in advance from a heating set temperature of the heater. The hot water supply on / off valve is turned on until reaching the value obtained by subtracting the judgment reference temperature, and when the detected temperature reaches the value obtained by subtracting the judgment reference temperature from the heating set temperature, the on / off timing control start condition is According to the configuration in which it is determined that the temperature is satisfied and the operation timing control that alternately repeats the on / off operation of the hot water supply on / off valve is started, the temperature of the hot water temperature incompatible heater is quickly increased to a temperature close to the heating set temperature. Then, the hot water supply on / off valve can be turned on and off to perform heating comfortably.

  Further, at least one of the heaters is a heating mat having a plate-like mat portion provided with a pipe through which hot water is passed, and a header connected to the mat portion to connect the pipe and the hot water terminal. According to a certain configuration, for example, an existing heating system is used, and a heating mat can be used even after retrofitting. Therefore, it is possible to realize a heating system that can comfortably use floor heating that is in great demand at a low cost.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 schematically shows an embodiment of the heating system according to the present invention, and FIG. 1 is a block diagram showing the control configuration thereof.

  As shown in FIG. 2, the heating system of this embodiment is formed by connecting a heating mat 51 to the hot water terminal 9 (9b) instead of the mobile fan convector 48 in the heating system shown in FIG. ing. The heating mat 51 is a non-conforming heater with a hot water temperature that has an optimal operating hot water temperature of 60 ° C. and that is different (lower) in the lower temperature direction than the temperature of hot water supplied from the heat source device 40 (here, 80 ° C.).

  A feature of the present embodiment is that such a hot water temperature incompatible heater is connected to one or more hot water terminals 9 (9b in this case) of the hot water terminals 9 of the heating system, and the hot water temperature incompatible heater (here Then, in the vicinity of the hot water terminal 9b to which the heating mat 51) is connected, a control configuration having a hot water temperature detecting means 52, a hot water supply on / off valve 53, and a valve on / off timing control means 54 as shown in FIG. It is provided.

  The hot water temperature detection means 52 detects the temperature of the hot water supplied to the hot water terminal 9b to which the heating mat 51 is connected. The hot water temperature detection means 52 adds the detected temperature to the valve on / off timing control means 54.

  The hot water supply on / off valve 53 performs a hot water supply on / off operation from the hot water terminal 9 to a corresponding hot water temperature incompatible heater (here, the heating mat 51).

  The valve on / off timing control means 54 takes in time information from the timepiece mechanism 55 and controls the timing of the on / off operation of the hot water supply on / off valve 53. The valve on / off timing control means 54 detects the detected temperature of the hot water temperature detecting means 52 based on the detected temperature detected by the hot water temperature detecting means 52 and the heating set temperature of the heating mat 51 set by the heating temperature setting means 56. And the timing of the on / off operation of the hot water supply on / off valve 53 are controlled in accordance with timing control information determined in advance corresponding to the heating set temperature of the heating mat 51.

  The timing control information is stored in the timing control information storage unit 57, and an example thereof is shown in FIG. For example, FIGS. 3A and 3B are examples of a plurality of individual data corresponding to the detected temperature detected by the hot water temperature detecting means 52 and the heating set temperature of the heating mat 51. FIG. These are examples of data that collectively represent the off time of the hot water supply on / off valve 53 corresponding to the detected temperature detected by the hot water temperature detecting means 52 and the heating set temperature of the heating mat 51.

  The data shown in FIG. 3A is data representing the transition of the on-time and off-time of the hot water supply on / off valve 53 in a time series when the detected temperature detected by the hot water temperature detecting means 52 is 80 ° C. Corresponding to the heating set temperature (for example, A ° C> B ° C> C ° C), when the heating set temperature is A ° C, the characteristic line α, when the heating set temperature is B ° C, the characteristic line β, and the heating set temperature is C ° C. Sometimes the characteristic line γ.

  Similarly, the data shown in FIG. 3 (b) is data representing the transition of the on-time and off-time of the hot water supply on / off valve 53 in a time series when the detected temperature detected by the hot water temperature detecting means 52 is 60 ° C. Corresponding to the heating set temperature (for example, A ° C> B ° C> C ° C), the characteristic line α is set when the heating set temperature is A ° C, and the characteristic line β is set when the heating set temperature is B ° C. At C ° C., the characteristic line is γ. When the temperature of the hot water supplied from the heat source device 40 is only 80 ° C. as in the present embodiment, only the data as indicated by the characteristic lines α to γ in FIG. May be given as

  Here, the data shown in FIG. 3A shows that the on-time of the hot water supply on / off valve 53 is a constant value (for example, about 3.5 minutes when the flow rate of hot water is about 1 liter / min), and the off time The OFF time is set shorter as the heating set temperature is higher. In the data shown in FIG. 3B, the ratio of the on time and the off time is changed with the on / off cycle being 20 minutes, and the ratio of the off time decreases as the heating set temperature increases (the ratio of the on time increases). It is set.

  Among the sizes of general heating mats 51 currently used for home use, the largest one is from the inlet side to the outlet side of the heating mat 51 when the flow rate of hot water is 1.0 liter / min. It takes less than 3.5 minutes for warm water to reach. Therefore, approximately 3.5 minutes, which is longer than this time, is given as the on-time of the hot water supply on / off valve 53 in the data shown in FIG.

  Further, for example, when the temperature of the hot water supplied from the heat source device 40 can be varied between 80 ° C. and 90 ° C., the on-time is set as a constant value, and for example, as shown in FIG. Data for changing the off time may be given when the temperature is 80 ° C. (characteristic line a) and when the hot water temperature is 90 ° C. (characteristic line b).

  Furthermore, for example, in the case of a device that can switch the hot water temperature supplied by the heat source device 40 in three stages, it is possible to adapt to each hot water temperature by providing characteristic lines corresponding to the respective temperatures.

  Note that the timing control information may be given by table data or may be given by an arithmetic expression, and the form of information is appropriately set.

  In the present embodiment, the valve on / off timing control means 54 turns on the hot water supply on / off valve 53 from the start of operation of the heating mat 51 until a predetermined on / off timing control start condition is satisfied, and the on / off timing control is performed. When it is determined that the start condition is satisfied, as described above, the on / off operation of the hot water supply on / off valve 53 is alternately performed based on the data of the characteristic line a in FIG. 3 (a) or FIG. 3 (c). The control of the operation timing to be repeated is started.

  Specifically, the valve on / off timing control means 54 determines that the on / off timing control start condition is satisfied when a predetermined standby time (for example, 20 minutes) has elapsed since the operation start of the heating mat 51, and supplies hot water. The operation timing control for alternately repeating the ON operation and the OFF operation of the ON / OFF valve 53 is started.

  For example, as shown in FIG. 4, the heating mat 51 includes a plate-like mat portion (mat material) 62 provided with a pipe 6 through which hot water passes, and the pipe 6 and the hot water connected to the mat portion 62. A header 61 that communicates with the terminal 9 is provided. The mat portion 62 is formed of foamed polystyrene or the like having a square shape. Usually, a groove for wiring the pipe 6 is formed on the surface of the mat portion 62, and the pipe 6 is accommodated and laid in the groove.

  In addition, a plurality of slits that alternately extend in the opposite side direction are formed from the opposite sides of the mat portion 62 in the longitudinal direction of the mat portion 62 (side length direction of the opposite side). For example, small joists 63 and small joists 65 made of wood or synthetic resin are accommodated in the slits. The intervals between the small joists 63 are equal, for example, at a pitch of 303 mm.

  There are also carpet-shaped heat dissipating mats such as small joists 63 and small joists 65 that are not provided with square members. It is also possible to apply such a heating mat 51 to this embodiment, and such a carpet-like heating mat 51 may be installed on the floor like an electric carpet, or may be installed under the floor. Some will do.

  On the upper surface of the mat portion 62, an aluminum foil (not shown in the figure) that is a sheet-like heat radiating member is usually provided so as to cover the pipe 6 and the joists (the small joists 63 and the small joists 65). Bonded and formed.

  Further, the configuration of the heat source device 40 applied to the present invention is not particularly limited, but in the present embodiment example, for example, it has the configuration shown in FIG. 5 and has a function of supplying hot water for heating. A gas combustion type heat source 40 having a function of supplying hot water to a hot water supply place such as a kitchen and a function of pouring hot water into a bathtub or reheating the hot water of the bathtub is applied. The configuration will be briefly described below.

  In the combustion chamber 50 of the heat source device 40, a hot water supply burner 1 (1a, 1b, 1c) as a heating device is disposed in the combustion chamber 50a, and a heating burner 2 (2a, 2b) is disposed in the combustion chamber 50b. A gas passage 49 is connected as a supply system for supplying fuel gas to the burners 1 and 2.

  The gas passage 49 is provided with electromagnetic valves 37 and 38 for opening and closing the passage and a proportional valve 39 for controlling the gas supply amount by the valve opening amount. Combustion fans 26 and 27 for supplying and exhausting combustion of the burners 1 and 2 are provided below the hot water supply burner 1 and the heating burner 2, respectively, and above the hot water supply burner device 1 and the heating burner 2. Are respectively provided with a hot water supply heat exchanger 7 and a heating heat exchanger 16.

  A water supply passage 5 is connected to the inlet side of the hot water supply heat exchanger 7, a hot water supply passage 11 is connected to the outlet side, and a flow rate sensor 4 and an incoming water temperature sensor 66 are provided in the passage on the water supply passage 5 side. A hot water supply temperature sensor 8 is provided in the passage on the hot water supply passage 11 side. The hot water supply passage 11 is connected to the return pipe 24 of the bath via the pouring passage 14, the pouring electromagnetic valve 13 and the conduit 19.

  A water inlet passage 41 is connected to the inlet side of the heat exchanger 16 for heating, and a water outlet passage 42 is connected to the outlet side. Temperature sensors 33 and 34 are provided in the water inlet passage 41 and the water outlet passage 42, respectively. Yes. The inlet passage 41 is provided with a discharge port side of the heating pump 31, and a heating return pipe 28 and a branch passage 43 are connected to the suction port side of the heating pump 31 via a heating system 35. The branch passage 43 is connected to the water discharge passage 42 through an electromagnetic valve 44.

  As the heating pump 31 is driven, hot water for heating passes through the heating return pipe 28, the water inlet passage 41, the heating heat exchanger 16, and the water outlet passage 42, and then passes through the heating outgoing pipe 29 to the hot water terminal 9 ( (Not shown in the figure), passes through the heater, and then returns to the heating return pipe 28 from the hot water terminal 9. At this time, when the heating burner 2 is combusted, the hot water temperature passing through the heating heat exchanger 16 is increased along with the combustion, and the hot water terminal 9 passes through the water discharge passage 42 and the heating outgoing pipe 29. The temperature of the hot water sent is raised.

  Further, FIG. 5 shows only one heating return pipe 28 and one heating outgoing pipe 29, but these passages have the number of hot water terminals 9 (for example, 2 in the case shown in FIG. 2). For example, by opening a thermal valve provided in the branched passage, the hot water can be continuously supplied to the desired hot water terminal 9 (9a, 9b). .

  The reheating of the bath using this heat source device 40 is performed by opening the electromagnetic valve 44 and passing hot water through the branch passage 43 so that the middle portion of the bath forward pipe 23 is covered in a manner covering the branch passage 43. This is performed by the reheating heat exchanger 15 provided and formed. Bathtub hot water is circulated through a reheating circulation path 25 for a bath formed by a return pipe 24 for a bath and an outgoing pipe 23 for a bath. In the figure, 18 is a bath temperature sensor, 22 is a running water switch, Reference numeral 21 denotes a circulation pump, and 20 denotes a water level sensor 20.

  The present embodiment is configured as described above. In the vicinity of the hot water terminal 9 (9b) to which the heating mat 51 is connected, the hot water temperature detecting means 52 and the hot water supply on / off valve 53 are provided. The on / off timing control means 54 is based on the detected temperature detected by the hot water temperature detecting means 52 and the hot water supply on / off valve 53 according to the timing control information determined in advance corresponding to the detected temperature and the heating set temperature of the heating mat 51. Controls the timing of the on / off operation.

  Therefore, even if the heating mat 51 having the optimum operating hot water temperature of 60 ° C. is connected to the hot water terminal 9b of the existing heating system that supplies hot water of high temperature such as 80 ° C. from the heat source device 40, for example, the valve on / off timing control means 54 By controlling the hot water supply on / off valve 53 and controlling the timing of supplying hot water to the heating mat 51 by controlling according to the above, the heating mat 51 can be operated satisfactorily and comfortable heating can be performed. Moreover, the heating system of the present embodiment can reduce the cost of system construction by using an existing heating system.

  Furthermore, even if the heat source device 40 is replaced, the valve ON / OFF timing control means 54 and the heating mat 51 having the optimum operating hot water temperature of 60 ° C. can be connected to the 80 ° C. hot water supply pipe and can continue to be used. When the heating mat 51 having the optimum operating hot water temperature of 60 ° C. is connected to the hot water supply pipe at 60 ° C., the heating mat 51 can be used without providing the valve on / off timing control means 54.

  Further, in the present invention, the valve on / off timing control means 54 performs the predetermined standby time from the start of operation of the heating mat 51 until the predetermined on / off timing control start condition is satisfied, that is, from the start of operation of the heating mat 51. The hot water supply on / off valve 53 is turned on until it elapses, and the hot water supply on / off valve is determined when it is determined that the on / off timing control start condition has been satisfied after the set standby time has elapsed from the start of operation of the heating mat 51. Since the control of the operation timing of alternately repeating the ON operation and the OFF operation of 53 is started, the temperature of the heating mat 51 can be quickly increased, and then the hot water supply ON / OFF valve can be turned ON / OFF to perform heating comfortably.

  In addition, although the present embodiment is configured to supply hot water of high temperature of 80 ° C. from the heat source device 40 to the hot water terminal 9, for example, both hot water of 60 ° C. and hot water of 80 ° C. can be supplied from the heat source device 40. In this case, the valve on / off timing control means 54 may perform on / off timing control of the hot water supply on / off valve 53 as follows.

  For example, when hot water of 60 ° C. is supplied from the heat source unit 40 without operating the air conditioner 47, the valve on / off timing control means 54 performs timing control corresponding to 60 ° C. as shown in FIG. When the on / off timing control of the hot water supply on / off valve 53 is performed according to the information, and when the 80 ° C. hot water is supplied from the heat source unit 40 by the operation of the air conditioner 47, the 80 ° C. correspondence shown in FIG. On / off timing control of the hot water supply on / off valve 53 may be performed according to the timing control information.

  In other words, if it is attempted to supply hot water at 60 ° C. in a system in which the temperature of the hot water supplied to the hot water terminal 9 is variable, the heating panel of the proposed example cannot cope with hot water supply at 60 ° C. at all. Even in a system in which the temperature of the hot water supplied to the hot water terminal 9 is variable, the valve on / off timing control means 54 controls the on / off timing of the hot water supply on / off valve 53 on an as-needed basis by appropriately providing timing control information. Thus, the heating mat 51 can be operated accurately and comfortable heating can be performed.

  In addition, this invention is not limited to the said embodiment, It can take various aspects. For example, in the above embodiment, the heating mat 51 is provided as a warm water temperature incompatible heater, but a warm water temperature incompatible heater other than the heating mat 51 may be connected to the hot water terminal 9 to form a heating system.

  Further, the number and location of the hot water terminals 9 provided in the heating system are not particularly limited, and are set as appropriate. At least one of the hot water terminals 9 is connected to a hot water temperature incompatible heater. Then, a heating system may be formed.

  Further, in the above embodiment, the valve on / off timing control means 54 determines that the on / off timing control start condition is satisfied when a predetermined set waiting time has elapsed since the start of operation of the heating mat 51. The on / off timing control start condition by the timing control means 54 is appropriately set.

  For example, as shown by a broken line in FIG. 1, a heating temperature detection means 58 is provided, and the heating temperature detection means 58 detects the heating temperature of a heater such as the heating mat 51, and this temperature is the heating set temperature of the heating mat 51. When a value obtained by subtracting a predetermined reference temperature for determination is reached, the valve on / off timing control means 54 determines that the on / off timing control start condition is satisfied, and the on / off operation of the hot water supply on / off valve 53 is determined. The operation timing control may be started alternately.

  In the above embodiment, the timing control information for performing the timing control of the on / off operation of the hot water supply on / off valve 53 by the valve on / off timing control means 54 is as shown in FIGS. However, the timing control information is set as appropriate. That is, the timing control information may be timing control information determined in advance corresponding to the detected temperature detected by the hot water temperature detecting means 52 and the heating set temperature of the warm water temperature incompatible heater such as the heating mat 51, For example, when the hot water temperature is 80 ° C. or 90 ° C., not only the off time of the hot water supply on / off valve 53 may be varied, but also the on time may be varied.

  In addition, as the heating mat 51 currently used becomes small to medium, the time from the inlet of the pipe 6 to the outlet changes from 3 minutes to 4 minutes, for example, depending on the length of the pipe 6. Therefore, you may provide the manual setting part which can control the ON time of the heating mat 51 according to the size of the heating mat 51. In addition, since the pipe 6 will be arrange | positioned twice when the size of the heating mat 51 becomes large, the size of the heating mat 51 is small → medium → large → extra large. Then, the time from the inlet of the pipe 6 to the outlet changes, for example, from 3 minutes → 4 minutes → 3 minutes → 4 minutes.
