OGB 30-200

A new generation of electrical water heaters

OGB heaters combine the properties of the GB family and the design of the OTG family. Internally, all the recognised characteristics of the GB family are retained, including the air-heating elements inserted into a metallic protective tube inside the heating flange. Both the tank and heating tubes are enamelled and protected with a magnesium anode against corrosion.

Distinguished by its distinctive countenance, this heater too defines a completely new character for such heaters in the new millennium.

The OGB heater is intended exclusively for vertical wall mounting.

With an appropriate mixer tap, it can also be used in a non-pressurised system.

  • Top Class Long Life model 
  • new angular shape
  • arbitrary water temperature setting to 75°C
  • additional functions:
    • thermometer for displaying water temperature inside the heater
    • display of electrical heating element operation
    • temperature setting options:
      • economical temperature and
      • protection against freezing
  • simpler maintenance and service
  • indirect tubular air-heating elements
  • 2 year general warranty, 7 year warranty for the tank
