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.

Storage tanks

Cut of the storage tankFunction of storage tanks NAD and NADO

Storage tanks are used to accumulate spare heat from its source.

Source can be:

  • central heating with solid fuel
  • solar system
  • stoves with heat exchangers
  • heat pump system etc.

Some storage tanks enable combining more sources of energy.

Storage tanks type NAD serve only to storage spare heat in the heating system. Type NADO allows also direct heating of hot water (HW) in inner enamel vessel or its pre-heating for another water heater.

Everything depends on temperature of heating water, which is stored in the tank. Solid fuel heating system in most cases allows direct heating of HW in inner vessel up to desired temperature, but solar or heat pump system will only pre-heat HW and it is necessary to place into the system a water heater or install a heating unit into storage tank, for example an electrical heating unit from TJ G 6/4" series or a heating flange from TPK series, to have HW at required temperature.

Storage tanks types NAD and NADO combined with a boiler with solid fuel assure optimal operation of the boiler at ideal temperature.

Accumulation tank accessories

Thermal insulation (see the drawing) is an accessory: strong 100 mm polyester fleece. The top cover, flange covers and hole caps are integral components. The insulation is supplied in separate packaging.

Other accessories for accumulation tanks are: a TPK flange heating unit and a TJ 6/4'' screw-in electric heating unit.
