  Further, in the present invention, the energy saving operation mode command transmission unit of the remote control device outputs an energy saving operation mode command for reducing the maximum hot water supply amount when a target achievement impossible determination signal is output from the target achievement success / failure determination unit. For example, since the amount of hot water used for hot water such as a shower depends greatly on the usage time, the amount of energy used can be efficiently reduced by reducing the amount of hot water supplied during hot water supply.

  In addition, in the present invention, if the user is conscious of energy saving execution, the user will not feel a great inconvenience even if the amount of hot water supply per unit time at the time of shower is somewhat small.

  Further, in the present invention, when a target achievement failure determination signal is output from the target achievement success / failure determination unit of the remote control device, the energy saving operation mode command transmission unit transmits hot water heated by the hot water supply heat exchanger through the hot water filling passage. According to the configuration that outputs the energy-saving operation mode command to reduce the maximum hot water supply amount during hot water supply excluding hot water supply by automatic hot water filling function to the bathtub, the capacity of automatic hot water filling is determined, Since the energy consumption cannot be reduced even if the maximum hot water supply amount is reduced, pouring water does not reduce the maximum hot water supply amount, and by reducing the hot water supply amount for other hot water supply, it is easy to use. However, the amount of energy used can be reduced efficiently while improving the environmental impact.

  The operation of the hot water supply function is started by turning on the operation switch of the remote control device 10 and opening a hot water tap (not shown) provided at the hot water supply destination of the hot water supply passage 11 in this state. When the hot water tap is opened, the control device 3 detects the flow rate exceeding the minimum operating flow rate through the water supply passage 5 by the flow rate sensor 4, burns the hot water burner 1, and heats the water passing through the hot water heat exchanger 7. Hot water is prepared, and the hot water is supplied to the hot water supply destination through the hot water supply passage 11.

  In the operation of the hot water supply function, the control device 3 determines the hot water temperature based on detection information of the incoming water temperature by the incoming water temperature sensor 6, the amount of hot water supplied by the flow rate sensor 4, and the hot water temperature (outlet temperature) by the hot water temperature sensor 8. The amount of gas supplied from the gas passage 49 is controlled by the valve opening amount of the proportional valve so that the hot water supply set temperature set by the remote control device 10 is reached, and hot water below the maximum hot water supply amount is appropriately supplied. The hot water supply operation is terminated when the hot water tap at the hot water supply destination is closed. That is, when the flow rate sensor 4 detects the stop of water flow by closing the hot-water tap, the control device 3 shuts off the gas supply to the hot-water supply burner 1 and stops the combustion of the hot-water supply burner 1.

  The operation of the hot water filling function is started by turning on the automatic switch of the remote control device 10 while the operation switch of the remote control device 10 is turned on. Then, the hot water solenoid valve 13 is opened, and the water passing through the hot water heat exchanger 7 becomes hot water by the combustion heating of the hot water burner 1 in the same manner as the operation of the hot water supply function.

The reheating operation of the bath is such that the circulating pump 21 is driven and hot water in the bathtub is circulated through the reheating circulation path 25 for the bath. In this embodiment, as described above, the heat for heating is circulated. The hot water passing through the reheating heat exchanger 15 is heated by using it.

  In this reheating operation, the bath temperature sensor 18 detects the bath temperature, and when the detected temperature reaches the set bath temperature, the combustion of the heating burner 2 is stopped, the circulation pump 21 and the heating pump 31 are stopped, and the solenoid valve. 44 is closed automatically. Further, if the turning-off switch is turned off during the chasing operation, the chasing operation is stopped during the chasing operation.

By this combustion control, the water passing through the hot water supply heat exchanger 7 is heated, and hot water can be discharged as hot water at the hot water supply set temperature set by the hot water supply related information input means 58.

  The hot water filling control means 71 receives an automatic switch on signal and controls the automatic hot water filling operation to the bathtub. Note that there are various ways of automatic hot water filling control, and in this embodiment, various automatic hot water filling control methods proposed so far and various automatic hot water filling control methods proposed in the future can be applied. Detailed description thereof will be omitted.

  The reheating control means 73 replaces the hot water heated by the heating burner 2 when the heat retention function after the automatic hot water filling is performed or when the reheating switch is turned on, as a reheating heat exchanger for a water-water heat exchanger. 15, the reheating operation of the bathtub hot water is controlled, and the temperature of the hot water in the bathtub is changed to the bath set temperature input by the bath operation related information input means 59.

  The heating combustion control means 74 receives the heating switch ON signal and controls the combustion of the heating burner 2 (2a, 2b) by controlling the opening / closing of the gas solenoid valve 38 and the valve opening amount of the proportional valve 39.

  In the present embodiment, when the functions of hot water supply including hot water filling, reheating, and heating are executed by the control of the control means 72, 73, 74 as described above, the opening degree of the gas proportional valve 39, The signal of the detection value of the flow sensor 4 is applied to the energy usage calculation means 54 of the remote control device 10 through the signal transmission / reception units 81 and 80 and a signal line (not shown).

  The energy use amount calculation means 54 receives the signal of the opening degree of the gas proportional valve 39 and the detection value of the flow rate sensor 4, and from the opening degree of the gas proportional valve 39 to the gas during combustion of the hot water supply burner 1 and the heating burner 2. The amount used is obtained and integrated for a preset period (for example, 30 days). In addition, when using hot water, the amount of gas used may be obtained by the equation of (amount of hot water × (hot water supply set temperature−incoming water temperature)) / efficiency. Further, the energy usage calculation means 54 obtains the water usage based on the detected value of the flow sensor 4 and integrates it during the set period. Although the timing of this calculation is not particularly limited, in this embodiment, for example, it is performed at a time when the operating rate of the combustion device 40 is small, such as at midnight.

  The target setting unit 52 sets an energy saving target value related to the energy usage amount for each predetermined setting period (for example, 30 days) of the combustion device 40. For example, the user can display the display unit of the remote control device 10. The energy saving target value is set by operating the operation button while looking at the display screen 57. The energy saving target value is usually set by the value of the gas charge or the water supply charge, but can also be set by the gas use amount or the water use amount. The energy saving set value is added to the target achievement pass / fail judgment unit 53.

  The target achievement success / failure determination unit 53 takes in time information from the clock mechanism 62, and determines whether or not the integrated value of the energy usage amount of the combustion device 40 for each set period exceeds the energy usage amount target value corresponding to the energy saving target value. When the integrated value of the energy usage exceeds the energy usage target value, a target achievement impossible determination signal is output, and the energy saving operation mode command transmission unit 55, the target achievement impossible display command unit 56, Add to.

Output energy saving operation mode command to be shortened.

  As a second embodiment, the energy saving operation mode command transmission unit 55 sets an interval of reheating of the bathtub hot water within the heat retention set time when the target achievement failure determination signal is output from the target achievement success / failure determination unit 53 (for example, Output an energy saving operation mode command to be lengthened (such as changing from 30-minute intervals to 1-hour intervals).

  As an example of the third embodiment, the energy saving operation mode command transmission unit 55 outputs an energy saving operation mode command for canceling the operation of the heat retaining function when a target achievement impossible determination signal is output from the target achievement success / failure determination unit 53.

  As a fourth example, the energy saving operation mode command transmission unit 55 displays the bath setting temperature display unit 65 in the display unit 57 of the remote control device 10 when the target achievement failure determination signal is output from the target achievement pass / fail determination unit 53. Without changing the bath set temperature to be displayed, an energy saving operation mode command for lowering the bath temperature by reheating to be lower than the bath set temperature is output. In this embodiment, the reheating includes both reheating that is appropriately performed during the automatic hot water filling operation, reheating during the heat retaining operation, and reheating that is performed when the reheating switch is pressed. Note that a selection unit that can be applied only to the tracking at the time of any one of the operations may be provided.

  As an example of the fifth embodiment, the energy saving operation mode command transmission unit 55 outputs an energy saving operation mode command for stopping the tracking function when the goal achievement failure determination signal is output from the goal achievement success / failure determination unit 53.

It is preferable to provide an energy-saving renewal stop display unit for performing a display indicating that the

  In the present embodiment, the energy saving function stop display unit 75 functions as an energy saving renewal stop display unit. For example, a display such as “cannot be reworked because the energy usage exceeds the target value” This is performed on the energy saving function stop display section 75. The display form is not particularly limited, and is appropriately set.

  In the case of the first to fifth embodiments as described above, each energy saving operation mode command is applied to the reheating control means 73 via the energy saving operation mode command receiving unit 70 of the combustion device 40.

  The combustion device 40 compares the amount of water flow per unit time in the pipe of the hot water supply heat exchanger 7 with a reference value that is determined before or at the beginning of use of the combustion device 40, and changes over time in the use of the combustion device 40 When the water flow rate becomes smaller than the reference value due to the difference between the reference value and the water flow rate, the maximum hot water supply amount is increased from No. 24 to No. 20 according to the number, for example. There is a case where a maximum hot water supply amount variable execution unit that is gradually reduced is provided such as No. 20 to No. 16.

  In this type of combustion apparatus 40, when the energy saving operation mode command for reducing the maximum amount of hot water supply is output from the energy saving operation mode command transmission unit 55, the maximum amount of hot water supply variable execution unit determines the maximum amount of hot water supply in advance.

  As a seventh embodiment, the energy saving operation mode command transmission unit 55 displays a hot water supply set temperature display unit 66 in the display unit 57 of the remote control device 10 when a target achievement failure determination signal is output from the target achievement success / failure determination unit 53. An energy saving operation mode command for lowering the temperature of the hot water supplied to the hot water supply destination to be lower than the set temperature of the hot water supply is output without changing the hot water supply set temperature to be displayed.

  As an eighth embodiment, the energy saving operation mode command transmission unit 55 outputs an energy saving operation mode command for stopping the hot water supply function when a target achievement failure determination signal is output from the target achievement success / failure determination unit 53.

  In this embodiment, the energy saving function stop display unit 75 also functions as an energy saving hot water supply stop display unit. For example, a display such as “Cannot supply hot water because the amount of energy used exceeds the target value” is displayed. The function stop display unit 75 is used. The display form is not particularly limited, and is appropriately set.

  In the case of these sixth to eighth embodiments, the energy saving operation mode command is applied to the hot water supply control means 72 via the energy saving operation mode command receiving unit 70 of the combustion device 40.

  As a ninth example, the energy saving operation mode command transmission unit 55 reduces the heating set temperature upper limit value when the heating function is executed when the target achievement failure determination signal is output from the target achievement pass / fail determination unit 53. A mode command is output.

  In this ninth embodiment, the remote control device 10 is connected to an outdoor temperature detecting means for detecting the outdoor temperature of the building where the heat source device is provided, and corresponds to the outdoor temperature detected by the outdoor temperature detecting means. The heating upper limit temperature determining means 76 shown by the broken line in FIG. 1 is determined to determine the heating set temperature upper limit value at the time of the energy saving operation mode command, and the energy saving operation mode command transmitting unit 55 is determined by the heating upper limit temperature determining means. If it is configured to output an energy-saving operation mode command with the temperature set to the heating set temperature upper limit value, for example, the heating set temperature upper limit value will be lowered unnecessarily even when it is very cold, giving the user discomfort. This is preferable because it can be suppressed and an appropriate heating set temperature upper limit value can be determined.

  As a tenth embodiment, the energy saving operation mode command transmission unit 55 sets the heating usage time for each unit period within the heating usage time setting upper limit value when the target achievement failure determination signal is output from the target achievement success / failure determination unit 53. Outputs the energy saving operation mode command to be restricted.

  In the tenth embodiment, the remote control device 10 is signal-connected to an outdoor temperature detecting means for detecting the outdoor temperature of the building where the heat source device is provided, and corresponds to the outdoor temperature detected by the outdoor temperature detecting means. A heating utilization time upper limit value setting unit 77 shown by a broken line in FIG. 1 is provided for determining and setting an upper limit value of the heating utilization time for each unit period at the time of the energy saving operation mode command. When the energy saving operation mode command is output with the time determined by the heating usage time upper limit setting means as the heating usage time setting upper limit value for each unit period, for example, the heating usage time setting upper limit value is unavoidable even when it is very cold. By making it small, it is possible to suppress an unpleasant feeling for the user, and an appropriate heating use time setting upper limit value can be determined, which is preferable.

  As an eleventh embodiment, the energy saving operation mode command transmission unit 55 does not change the heating set temperature displayed on the heating set temperature display unit 67 when the target achievement failure determination signal is output from the target achievement pass / fail determination unit 53. In addition, an energy saving operation mode command for lowering the heating temperature to be lower than the heating set temperature is output.

  As an example of the twelfth embodiment, the energy saving operation mode command transmission unit 55 outputs an energy saving operation mode command for stopping the heating function when the target achievement failure determination signal is output from the target achievement pass / fail determination unit 53.

  In the case of the twelfth embodiment, when the energy saving operation mode command for stopping the heating function is output from the energy saving operation mode command transmission unit 55 to the remote controller 10, the combustion device 40 of the combustion device 40 is operated as in this embodiment. An energy saving operation display command unit 69 that outputs a display command indicating that the heating function is stopped, and that the heating function is stopped by the energy saving operation when the display command is output from the energy saving operation display command unit 69. It is preferable to provide an energy-saving heating stop display unit that performs display.

  In the present embodiment example, the energy saving function stop display unit 75 also functions as an energy saving heating stop display unit. For example, a display such as “cannot be heated because the energy usage exceeds the target value” is used for energy saving. This is performed on the function stop display unit 75. The display form is not particularly limited, and is appropriately set.

  In the case of these ninth to twelfth embodiments, the energy saving operation mode command is applied to the heating combustion control means 74 via the energy saving operation mode command receiving unit 70 of the combustion device 40.

  In the present embodiment, the energy saving operation mode command transmission unit 55 is configured to be able to output a plurality of items of energy saving operation mode commands so that two or more of the first to twelfth embodiments can be executed. Has been.

  In the present embodiment, the remote control device 10 is provided with energy saving operation mode execution presence / absence setting means 51. The energy saving operation mode execution presence / absence setting means 51 determines whether or not the energy saving operation mode is executed. The energy saving operation mode execution presence / absence setting means 51 determines whether or not the energy saving operation mode is executed for each item of the energy saving operation mode command. Item-specific setting means for determining That is, in this embodiment, only the energy saving operation mode command determined by the energy saving operation mode execution presence / absence setting unit 51 is selectively output from the energy saving operation mode command transmission unit 55.

  The present embodiment is configured as described above, and the target value setting means 53 of the remote control device 10 saves the energy saving target value related to the amount of energy used for each predetermined setting period (for example, 30 days) of the combustion device 40. When the energy saving operation mode execution presence / absence setting means 51 sets the energy saving operation mode to be executed, the target achievement pass / fail judgment unit 53 sets the energy usage target value corresponding to the energy saving target value by the integrated energy usage value. A determination is made as to whether it has been exceeded.

  When it is determined that the integrated value of the energy usage exceeds the energy usage target value, the energy saving operation mode command is output from the energy saving operation mode command transmission unit 55, and the operation in the energy saving operation mode is executed. .

  For example, as shown in FIG. 3A, when the target achievement pass / fail determination unit 53 determines for each set period whether or not the integrated value of the energy usage exceeds the energy usage target value corresponding to the energy saving target value. In addition, 30 days after the energy saving target value is set by the target value setting means 53, whether or not the target is achieved is judged, and the integrated value of the energy usage exceeds the energy usage target value corresponding to the energy saving target value. Sometimes the target achievement impossibility determination signal is output, the energy saving operation mode command is output, and the operation in the energy saving operation mode is executed.

  If comprised in this way, the timing of execution of an energy-saving operation mode can be measured for every setting period, an energy usage-amount can be made small appropriately, and the influence on an environment can be improved as a result.

  Further, the target achievement success / failure determination unit 53 determines whether or not the integrated value of the energy usage amount of the combustion device up to the timing exceeds the energy usage amount target value at every timing when the set period is divided into a plurality of times. For example, as shown in FIG. 3B, even before the set period is reached, if the integrated value of the energy usage exceeds the energy usage target value corresponding to the energy saving target value, the target cannot be achieved. The determination signal is output, the energy saving operation mode command is output, and the operation in the energy saving operation mode is performed.

  With this configuration, when the energy usage is large and the integrated value exceeds the energy usage target value before reaching the set period, the energy saving operation mode can be executed early, The impact on the environment can be improved.

  The energy saving operation mode command transmission unit 55 outputs the energy saving operation mode command only for the items selected and determined by the energy saving operation mode execution presence / absence setting means 51 in the first to twelfth embodiments. Is performed.

  Further, in this embodiment, when the goal achievement failure determination signal is output from the goal achievement success / failure determination unit 53, a display indicating that the goal has not been achieved is performed. By performing this, the user can be made aware of the reason for executing the energy saving operation mode.

  Furthermore, in the present embodiment example, the target achievement success / failure determination unit 53 determines, for each set period, whether or not the integrated value of the energy use amount of the combustion device for each set period exceeds the energy use amount target value, and When it is determined that the integrated value of the energy usage is within the energy usage target value, a target achievement determination signal is output, and the target achievement pass / fail determination unit 53 receives the target while the energy saving operation mode is being executed. When the achievement determination signal is output, the energy saving operation mode command is canceled. Therefore, when the energy saving operation mode is executed and the integrated value of the energy consumption is reduced and the energy saving operation mode cancel command is output, the energy saving operation mode can be canceled as shown in FIGS. .

  Further, in the present embodiment, when the energy saving target value set by the target value setting means 52 is changed in the direction of increasing during execution of the energy saving operation mode, for example, as shown by an arrow A in FIG. The energy saving operation mode command can be canceled.

  That is, according to the present embodiment, the energy-saving operation mode is canceled at an appropriate timing by determination for each set period or by changing the energy-saving target value as necessary, and an easy-to-use combustion system can be constructed.

  Furthermore, in this embodiment, the following effects can be obtained by appropriately selecting the energy saving operation mode to be executed.

  For example, in the first embodiment in which the heat retention set time for executing the heat retention function of the combustion device 40 is shortened, for example, the heat retention set time is when the user enters the bathtub when the heat retention function operation starts for a while. However, since it is often set so that it is put in hot water of the set temperature, if the user bathes early, the user will not be inconvenienced even if the heat retention setting time is shortened, and the energy consumption will be reduced. It can be reduced and the impact on the environment can be improved.

  Further, according to the second embodiment in which the interval of reheating of the bathtub hot water within the heat retention set time by the heat retention function is increased, the interval of reheating of the bathtub hot water within the heat retention set time is usually slightly increased. However, since the bath water temperature does not drop significantly at the timing when the user tries to take a bath, the user is not so inconvenient, the energy consumption can be reduced, and the influence on the environment can be improved. .

  Further, according to the third embodiment in which the operation of the heat retaining function is canceled, the user feels a little inconvenience when the heat retaining function is canceled, but if the user manually retreats, the user takes a bath. And energy consumption can be reduced and the impact on the environment can be improved.

  Furthermore, according to the fourth embodiment in which the bath temperature by the reheating is made lower than the bath set temperature without changing the bath set temperature displayed on the bath set temperature display unit 65 of the remote control device 10, the energy saving operation is performed. Even if the temperature of the bath is changed to be somewhat low depending on the mode, the user can see the set temperature of the bath, and the energy consumption can be reduced without knowing the change.

  Further, according to the fifth embodiment in which the reheating function is stopped, according to the configuration configured to output the energy saving operation mode command, the effect of reducing the amount of energy used can be reduced by stopping the reheating function. Can be increased. In this configuration example, according to the configuration in which the energy saving operation mode command is output and the reheating function of the combustion device is displayed, the user is made aware of the recharging function stop by the energy saving operation mode command. Therefore, it is possible to prevent the user from erroneously determining that the combustion apparatus is out of order.

  Furthermore, according to the sixth embodiment in which the maximum hot water supply amount of the combustion device 40 is reduced, the amount of hot water used for hot water supply such as a shower greatly depends on the usage time, so the hot water supply amount during hot water supply is reduced. As a result, the amount of energy used can be reduced efficiently, and the influence on the environment can be improved without causing the user to feel uncomfortable.

  Furthermore, according to the seventh embodiment, the hot water supply temperature displayed on the hot water supply set temperature display unit 66 of the remote control device 10 is not changed, and the temperature of the hot water supplied to the hot water supply destination is made lower than the hot water supply set temperature. Even if the temperature of the hot water supply is changed to be somewhat low by the energy saving operation mode, the user can see the change of the hot water supply set temperature and can reduce the amount of energy used without knowing the change.

  Furthermore, according to the said 8th form example which stops a hot water supply function, the reduction effect of energy usage can be enlarged by stopping a hot water supply function. In this embodiment, by displaying that the hot water supply function is stopped by the energy saving operation mode command, the user can grasp the hot water supply function stop by the energy saving operation mode command. It is possible to prevent misjudgment as a device failure.

  Furthermore, according to the ninth embodiment that lowers the heating set temperature upper limit value of the combustion device 40, by lowering the heating set temperature upper limit value, it is possible to efficiently execute the energy saving operation and improve the influence on the environment. .

  Furthermore, according to the tenth embodiment that limits the heating usage time for each unit period within the heating usage time setting upper limit value, by limiting the heating usage time for each unit period within the heating usage time setting upper limit value, Energy saving operation can be executed efficiently, and the impact on the environment can be improved.

  Furthermore, according to the eleventh embodiment in which the heating temperature is set lower than the heating temperature without changing the heating temperature displayed on the heating temperature setting section 67, the temperature of the heating is slightly lower depending on the energy saving operation mode. Even if the change is made, the user can reduce the amount of energy used without knowing and not knowing the change by viewing the heating set temperature display.

  Furthermore, according to the twelfth embodiment for stopping the heating function, the effect of reducing the amount of energy used can be increased by stopping the heating function. In this embodiment, by displaying that the energy saving operation mode command is output and the heating function of the combustion device is stopped, the user can grasp the heating function stop by the energy saving operation mode command. It is possible to prevent the user from erroneously determining that the combustion device is malfunctioning.

  Further, in this embodiment, when the energy saving operation mode command transmission unit 55 outputs all the energy saving operation mode commands for stopping the reheating function, stopping the hot water supply function, and stopping the heating function, the function for energy saving is stopped. Only the function stop display and the clock display on the display unit 75 may be performed on the display unit 57 of the remote control device 10, and in this way, the power consumption of the remote control device 10 can be reduced. .

  In addition, this invention is not limited to the said embodiment example, Various aspects can be taken. For example, in the above embodiment, the energy saving operation mode command transmission unit 55 can output a plurality of items of energy saving operation mode commands so that two or more of the first to twelfth embodiments can be executed. However, the energy saving operation mode command transmission unit 55 may output only one energy saving operation mode command.

  In this case, the energy-saving operation mode execution presence / absence setting unit 51 does not need to be provided with an item-specific setting unit as long as it can determine whether or not to execute one energy-saving operation mode command.

  The energy saving operation mode execution presence / absence setting means 51 may be omitted. In this case, it is preferable to set the contents of one or more types of energy saving operation mode commands output by the energy saving operation mode command transmission unit 55 in consideration of usability.

  Further, as shown by a broken line in FIG. 1, a target achievement success / failure estimation unit 68 is provided in the remote control device 10, and the integrated value of the energy usage amount of the combustion device 40 is calculated by the target achievement success / failure estimation unit 68 within the set period. Whether the energy usage target value corresponding to the energy saving target value is exceeded or not may be estimated in consideration of the transition of the energy usage amount, and the target achievement determination may be made based on the estimation result.

  That is, instead of determining whether or not the integrated value of the energy use amount of the combustion device exceeds the energy use amount target value for each set period, the target achievement pass / fail determination unit 53 uses the target achievement pass / fail estimation unit 68 to, for example, As shown in FIG. 4, the slope of the characteristic line “a” indicating the transition of the energy usage amount indicates that the energy usage target value E after the set period (here, 30 days) and the start time of the set period (period 0) For example, it is judged that the target cannot be achieved when the integrated value of the energy usage amount is estimated to exceed the energy usage target value when the set period has elapsed, for example, exceeding a preset allowable range. It can be configured to output a signal.

  In this case, the display on the target achievement impossibility display section 64 can be performed by, for example, a character display such as “If the user keeps using it as it is, the goal cannot be achieved. The display form is not particularly limited and can be set as appropriate.

  As described above, when the target achievement success / failure estimation unit 68 is provided to estimate the integrated value of the energy usage amount, the energy usage amount is large, and the energy usage amount target is reached before the integrated value reaches the set period. When the value is exceeded, the energy saving operation mode can be executed early, and the influence on the environment can be improved.

  Note that there is provided means for selecting whether the goal achievement pass / fail judgment by the goal achievement pass / fail judgment unit 53 is performed based on the above estimation or based on the integrated value of the energy usage, as in the above embodiment example, Either method may be selected by this selection means.

  Further, the target achievement success / failure determination unit 53 determines, for each set period, whether or not the estimated value of the energy usage amount of the combustion device for each set period exceeds the target value for energy use, and the estimated value of the energy use amount May be configured to output a target achievement determination signal when it is determined that is within the energy usage target value. Also in this case, the same effect as the above embodiment can be obtained by the determination by the goal achievement pass / fail determination unit 53.

  Further, when the target achievement pass / fail judgment unit 53 determines that the integrated value of the energy usage of the combustion device 40 for each set period is within the energy usage target value, the energy usage with respect to the energy usage target value. An energy-saving target value variable setting unit that obtains a ratio of the integrated value of the energy and variably sets the energy usage target value within the next set period as the ratio decreases according to the size of the ratio. It is good also as a structure which has.

  For example, when the ratio of the integrated value of energy usage to the target value of energy usage is 100%, the energy saving target value is set to the same as the previous set value, and the integrated value of energy usage relative to the target value of energy usage is set. When the ratio is 95%, set the energy saving target value 3% larger than the previous setting value. When the ratio of the integrated value of energy usage to the energy usage target value is 90%, set the energy saving target value to the previous value. It may be set to 5% larger than the set value. Further, the automatic setting value of the energy saving target value may be given by graph data or an arithmetic expression corresponding to the ratio of the integrated value of the energy usage amount to the energy usage amount target value.

  Thus, if it comprises the energy-saving target value variable setting part, the energy usage-amount in the period which has a period of multiple times of a setting period can be made into an average appropriate value.

  Furthermore, in the above embodiment, the setting period for determining the energy saving target value is 30 days. However, the setting period may be one week (7 days) or 10 days, and is set as appropriate. .

  Furthermore, in the above embodiment, the combustion device 40 is a device having a hot water supply function, a bath reheating function, and a heating function, but the combustion device may have one or more of these functions. Well, for example, it has two functions of a combustion device having only a hot water supply function, a combustion device having only a bath reheating function, a combustion device having only a heating function, a hot water supply function, a bath reheating function and a heating function Various combustion devices such as a combustion device can be applied, and details of the device configuration can be set as appropriate.

  For example, FIG. 5 shows an example of a combustion apparatus having a hot water supply function and a bath reheating function. In such a combustion apparatus, the bath reheating is performed by using a bath burner 46 and the bath burner 46. The recirculation circuit 25 is provided with a reheating heat exchanger 15 heated by the recirculation heat exchanger 15. In this case, when the heat retention time and the reheating interval are controlled by the energy saving operation mode command, these controls are the combustion control of the bath burner 46 and the drive control of the circulation pump 21 for the bath provided in the reheating circulation path 25. Is done.
