Pressurised electric water heaters
Mechanical control of the conventional OTG SLIM water heaters have been replaced with a modern electronic control unit . Modern control unit with LED indicators and water temperature display unit, and the added EcoSmart feature additionally highlight the already modern and visually appealing design with rounded corners, and allow reaching heater efficiency in compliance with the Environmental Directive.
ADVANTAGES:
- Supply of several outlets
- Vertical wall mounting
- High-quality insulation for lower heat losses
- Electric immersion heating element
- Electronic control unit
- Heater on/off and temperature adjustment key
- Temperature adjustable from 10 °C to 75 °C
- 7 LED temperature indicator
- Dry firing protection
- Overheating protection
- Anti-Legionella function
- Heating element operation indicator
- Error/fault indicator
- Working pressure 6 to 9 bar
- Anti-corrosion tank protection with enamel and a magnesium anode
- Available volumes/capacities: 30 l, 50 l, 80 l, 100 l, 120 l
