Ensure adequate space around the unit for maintenance and ventilation. The unit dimensions are 45 cm (depth) x 50.4 cm (width) x 91.6 cm (height).
Water Connections
Connect the cold water inlet (R 1/2) and hot water outlet (R 1/2) using the provided connection pipes. Ensure all connections are watertight. The integrated ball valve facilitates quick draining.
Electrical Connection
The electrical connection must be performed by a qualified electrician. The unit supports heating power from 2 kW to 6 kW, adjustable by repositioning internal bridges. The operating voltage is 400 Volts.
Important: Only connect the water heater to the electrical supply after it has been completely filled with water and all water connections are secure.
Operating Instructions
Initial Start-up
- Ensure the water heater is completely filled with water by opening a hot water tap until water flows freely and air is purged from the system.
- Switch on the electrical supply to the unit.
- Set the desired water temperature using the continuous temperature regulator.
Temperature Control and SmartControl
The eloSTOR VEH 80/8 allows for continuous temperature adjustment between 40 °C and 85 °C. An energy-saving position is available at 60 °C.
Figure 3: Front view of the eloSTOR VEH 80/8, showing the control panel with temperature adjustment and display.
The integrated SmartControl function learns your usage habits and heats water just before it's needed, minimizing standby energy loss and reducing overall energy consumption. This feature can save over 7% of energy requirements.
For immediate hot water, a quick heating button is available to rapidly heat the water to the set temperature.
Operating Modes
The unit supports single-circuit, dual-circuit, or boiler operation. The universal heating flange allows for flexible configuration.

- Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Troubleshooting
This section provides solutions to common issues. For problems not listed here, or if solutions do not resolve the issue, contact Vaillant customer support or a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No electrical supply; temperature setting too low; unit not filled with water. | Check circuit breaker; increase temperature setting; ensure unit is filled before powering on. |
| Water not hot enough | Temperature setting too low; high hot water demand exceeding recovery rate. | Increase temperature setting; use quick heating function; allow time for reheating. |
| Water leakage | Loose connections; damaged seals or pipes. | Tighten connections; contact a qualified technician for inspection and repair. |
| Unusual noises | Sediment buildup; air in the system. | Drain and flush the unit (consult technician); purge air from the system. |
