OKHE SMART

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.

Heater design

  • Indirect water heaters designed to place on the floor with volumes between 100–250 litres with an enamelled vessel and powerful heat exchanger used to heat hot water from external sources. Heaters with volumes 200 and 250 litres are produced in versions with two heat exchangers used for connection from two heating water sources (e.g. gas boiler + alternative source) . By connecting of both heat exchangers in series the user may get hot water source with the output up to 44 kW. The heater is equiped with hot water heating temperature regulation system (thermostat controlling the three-way valve or circulation pump) for the voltage 230 V/50 Hz, safety valve and circulation outlet.

Most common use

  • Year-roung heating of hot water using heating water from gas boiler with priority connection into hot water heating. In the OKC x NTRR type the gas boiler may be combined with an alternative heat source or by connecting both heat exchangers into series will become indirect heating reservoir for the boilers with the capacity above 24 kW.
