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.

Suspended, vertical

Character

Operating position – vertical (suspended on the wall)

  • Combined storage water heaters designed for suspension on the wall with volumes of 80–200 litres. The manufacturer throughout all the history of the heaters production keeps same pitch of the anchoring bolts in order to assure easy replacement of time-expired water heaters. It is also possible to buy the suspension for the pitch of the anchoring bolts reaching 350 mm.

Heating options

  • Electric power. Ceramic heating element controlled by the operating thermostat and secured by the safety thermostat (thermal fuse).The thermal range is 5–74 °C. Connection voltage is 1-PE–N/AC 230 V/50 Hz. The IP 44 electric shielding enables mounting of heaters above baths.
  • Heat exchanger. The heater may be connected to an external hot water source with the max. temperature of 110 °C and pressure of 1 MPa . Heater with the adequate output of the heat exchanger must be linked depending on the output of the source. The heat exchanger works in forced circulation mode and also in self-circulation system. The heating water regulation sensor may be inserted into the common receiver with electric installation sensors.

Most common use

  • Preparation of hot utility water for premisses with hot water central heating using gas and solid fuels during a winter season.
  • Electric heating off the heating period is enabled with the possibility to use the low tariff of electric supply (night tariff).

Accessories

  • Safety valve

Optional equipment

  • Circulation input
  • Two and three-phase connection 400 V/50 Hz
  • The heating element with higher power output, max. 4 kW
