OKHE SMARTSmart water heater with electronic thermostat and the option of connection to HDO. It includes autodidactic algorithm and heats water if required. It is possible to switch to several modes (MANUAL, MANUAL HDO, OPTIMUM, PROG, SMART, ANTI FREEZE). The heater is controlled by means of the operating system Android/iOS.


Heating flange


This device is used for electric heating of hot utility water designed for fitting into the flanged hole of OKCE 100–300 S and OKC 100–300NTR(NTRR)/BP water heaters. The heating unit is equipped with ceramic heating elements and operating and safety thermostat with the hot utility water temperature regulation range 5–74 °C. Heating flange TPK 210/12 can also be used in storage tanks with flange, thus NAD v1, NAD v3-v5 a NADO v1-v3.
