The GBU generation of heaters has been developed within the GB family and contains all its outstanding features; additionally – due to its universal design – it also offers the possibility of vertical and horizontal wall mounting (with connection tubes on the left side).
An air heating element is inserted into a protective metallic tube within the heating flange. It allows for the maximum degree of protection of the enamelled tank surface in combination with a magnesium anode, reduces sedimentation and facilitates maintenance. The GBU heater is intended for the supply of a single outlet or for the central supply of hot water to numerous outlets from a single heater.
With an appropriate mixer tap, it can also be used in a non-pressurised system.
