Pressurised electric water heaters
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 offers the possibility of vertical and horizontal wall mounting (with connection tubes on the left side).
For better energy performance is available model with EcoSmart function GBU SM.
ADVANTAGES:
- Volumes: 50, 80, 100, 120, 150, 200 l.
- Vertical or horizontal wall mounting (connecting tubes are on the LEFT side).
- High-quality insulation for lower heat losses
- Heating flange with tubular air heating elements
- Electronic control unit
- Heater on/off and temperature adjustment key
- Temperature adjustable from 10 °C to 75 °C
- 7 LED temperature indicator
- Dry fire protection
- Overheating protection
- Anti-Legionella function
- Heating element operation indicator
- Error/fault indicator
- Working pressure 6 to 9 bar
