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.

With side flange

Character

BP design – side flange

  • Series of enamelled indirect heaters designed to be placed on the floor with volumes between 160–250 litres with enamelled vessel and one or two (beginning from the 200 l types) high performance heat exchangers for heating of hot water from external sources or combination of different sources. By connecting of both heat exchangers in series a user may get hot water source with the output up to 57 kW. The heater is equipped with hot water temperature regulation system (thermostat controlling the three-way valve or circulation pump) for the voltage 230 V/50 Hz and up to volumes 200 l with a safety valve and circulation outlet.
  • In the lower part of the heater is a flange manhole used to clean the inside of the vessel and eventual insertion of the auxilliary electric heating of the TPK series as an accessory. For the use of heaters for the solar system the heaters with the volume above 200 litres are equipped with a 6/4" neck located above the solar exchanger for the electric heating unit TJ from the accessories section.

Most common use

  • Year-round heating of hot water using heating water from the 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.
