     The electrolyzed water IL delivered to the receiving portion  190 , for example heated electrolyzed water IL, may be used for a variety of applications. 
     The heated electrolyzed water IL may be directly supplied where hot water is needed. To this end, as an optional embodiment, the heated electrolyzed water IL in the receiving portion  190  may be transferred to a separate tank not illustrated. 
     In addition, as an optional embodiment, the heated electrolyzed water IL in the receiving portion  190  may be used as a supply of a heat source.

     For example, the temperature sensing portion may be formed and disposed to measure the temperature of the electrolyzed water IL in the second flow path portion  102  in real time. 
     As an optional embodiment, the temperature sensing portion  140  is connected to the second flow path portion  102  and reduces or prevents temperature measurement accuracy reduction, performance degradation, and occurrence of malfunctions or defects due to the heated electrolyzed water IL flowing through the first flow path portion  101 . 
     As an optional embodiment, a cooling portion not illustrated may be disposed adjacent to the temperature sensing portion  140  to prevent overheating of the temperature sensing portion  140 . 
     The control portion  130  may be formed to control a current applied to the electrode portion  120 . 
     As an optional embodiment, the control portion  130  may be connected to the conductive portion WL connected to the electrodes  121 ,  122 , and  123  of the electrode portion  120 . 
     Through this, the control portion  130  may control the current applied to the electrode portion  120  in real time. 
     At this time, the control portion  130  may check an amount of current applied to the electrode portion  120  and control the current to increase or decrease according to a set value. 
     As an optional embodiment, the control portion  130  may check the amount of current applied to the electrode portion  120  in real time and control the current to increase or decrease according to the set value, thereby reducing a rapid temperature change of the electrolyzed water IL. 
     In addition, as an optional embodiment, the control portion  130  may be connected to the temperature sensing portion  140 , and may control the current applied to the electrode portion  120  by using the temperature measured by the temperature sensing portion  140 . For example, when the temperature measured by the temperature sensing portion  140  exceeds a normal range, the current applied to the electrode portion  120  may be decreased than a normal range, and when the temperature measured by the temperature sensing portion  140  is less than the normal range, the current applied to the electrode portion  120  may be increased above the normal range. 
     In this case, the control portion  130  may have information on “decreased temperature” or “increased temperature” set higher or lower than the normal range as a preset value. 
     In addition, as another example, the control portion  130  may change the current according to the “increased width” and “decreased width” corresponding to a difference value obtained by comparing the normal range of the measured temperature, and the control portion  130  may have the information on a value of the current to be changed according to the preset “increased width” and “decreased width”. 
     As an optional embodiment, the control portion  130  may be separated from the temperature sensing portion  140  and connected through communication. 
     As another example, the control portion  130  may be disposed to be connected to the temperature sensing portion  140 , and specifically, the control portion  130  may be disposed on a surface of the temperature sensing portion  140 . 
     In addition, as another example, the control portion  130  may be integrally formed with the temperature sensing portion  140 . 
     The control portion  130  may have various types of easily changing current. For example, the control portion may include various types of switches, and may include a static relay such as a solid-state relay SSR for sensitive and rapid control. 
     As an optional embodiment, a cooling portion not illustrated may be disposed adjacent to the control portion  130  so that overheating of the control portion  130  is prevented. 
     The electrode boiler system of this embodiment may heat the electrolyzed water in the body portion by controlling the current applied to the electrode of the electrode portion. The heated electrolyzed water is delivered to the receiving portion through the first flow path portion, and the heated electrolyzed water may be used as the heat source to heat others directly or indirectly in the receiving portion. 
     In addition, a process in which the electrolyzed water flows from the receiving portion to the body portion, and the electrolyzed water is heated and delivered may be repeated. 
     Through this, hot water or heat may be easily supplied, current applied to the electrode portion may be easily controlled, and electrolyzed water may be stably heated. 
     In addition, the body portion receiving the electrolyzed water, the receiving portion receiving the electrolyzed water, the entire or inner surface of the first flow path portion, and the entire or inner surface of the second flow path portion are formed of insulating material, so the leakage of current is reduced or blocked when the electrolyzed water flows, resulting in implementation of a safe and efficient electrode boiler system.

     As an optional embodiment, in the electrode boiler system  400  of the present embodiment, at least where the electrolyzed water IL flows or the electrolyzed water IL is present, all regions in contact with the electrolyzed water IL may include an insulating layer or a Teflon resin layer such as an anti-static Teflon resin layer. 
     The electrode boiler system of this embodiment may heat the electrolyzed water in the body portion by controlling the current applied to the electrode of the electrode portion. The heated electrolyzed water is delivered to the heat exchange portion through the first flow path portion, and the heated electrolyzed water may be used as the heat source in the heat exchange portion, and may provide heat to the heat exchange portion adjacent to the heat receiving portion. 
     In addition, a process in which the electrolyzed water flows from the heat exchange portion to the body portion, and the electrolyzed water is heated and delivered may be repeated. 
     Through this, hot water or heat may be easily supplied, current applied to the electrode portion may be easily controlled, and electrolyzed water may be stably heated. 
     In addition, the body portion receiving the electrolyzed water, the heat exchange portion receiving the electrolyzed water, the entire or inner surface of the first flow path portion, and the entire or inner surface of the second flow path portion are formed of insulating material, so the leakage of current is reduced or blocked when the electrolyzed water flows, resulting in implementation of a safe and efficient electrode boiler system. 
     In addition, in the electrode boiler system of the present embodiment, the region in contact with the electrolyzed water may include an inner layer, for example, an anti-static Teflon resin layer, thereby improving electrical stability as well as thermal efficiency. 
     As a specific experimental example, it was confirmed that 1720 watts W are required to generate 3600 watts W when an anti-static Teflon resin layer is used, whereas it was confirmed that 3440 watts W are required to generate 3600 watts W when other layer, for example, a resin layer is used, and a coefficient of performance 2.09 when the anti-static Teflon resin layer is used may be increased than a coefficient of performance 1.05 when a general resin layer is used.
