The OTG generation is distinguished by its original octahedral design, endowing it – and thus any room in which it is fitted – with a completely new character that heralds the dawn of the new millennium. OTG heaters thus flirt with the future and mark a new trend in design at Gorenje.
The tank is manufactured from a high-quality steel sheet and is protected against corrosion by an enamel coating and a protective magnesium anode. The thick insulation made of hard polyurethane foam keeps thermal losses to a minimum.
The OTG heater is intended exclusively for vertical wall mounting.
With an appropriate mixer tap, it can also be used in a non-pressurised system.

Values are valid for mixing water with temperature of 15 °C from the cold inlet with water at 65 °C from the heater (standard SIST EN 60379:2005).
Measured at 20 °C ambient temperature, and 65 °C water temperature in the heater (standard SIST EN 60379:2005).
