2. Safety Information
Always adhere to local regulations and standards for electrical and plumbing installations. Failure to do so may result in property damage, injury, or death.
- Installation must be performed by a qualified professional.
- Ensure the power supply matches the specifications of the water heater.
- Do not operate the water heater if it is damaged or malfunctioning.
- Before any maintenance or repair, disconnect the appliance from the main power supply.
- Keep flammable materials away from the water heater.
- This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
3. Product Overview
The THERMOR Malicio 3 water heater features advanced steatite technology, where the heating element is encased in an enameled steel sleeve. This design prevents direct contact between the resistance and water, significantly reducing limescale buildup and extending the lifespan of the heating element.
Key components include:
- Enamel-lined steel tank
- Steatite heating element
- Electric thermostat for temperature control
- Multiposition mounting brackets (for vertical or horizontal installation)
- Integrated control panel
4. Setup and Installation
The THERMOR Malicio 3 water heater offers flexible installation options, allowing it to be mounted vertically or horizontally to suit your space requirements. Due to its weight (32.5 kg) and electrical/plumbing connections, professional installation is strongly recommended.
4.1 Site Selection
Choose a location that is structurally sound to support the weight of the water heater when full (approximately 97.5 kg for the 65L model). Ensure adequate clearance for maintenance and proper ventilation. The appliance is designed for indoor use and must be protected from freezing temperatures.
4.2 Mounting
Use the provided mounting brackets to securely fasten the water heater to a wall. Ensure the wall material can safely bear the full weight. The multiposition design allows for either vertical or horizontal orientation. Refer to the detailed diagrams in the included physical manual for specific mounting patterns.

4.3 Plumbing Connections
Connect the cold water inlet and hot water outlet pipes according to standard plumbing practices. Install a safety group (pressure relief valve) on the cold water inlet to prevent overpressure. Ensure all connections are watertight.
4.4 Electrical Connection
The water heater requires a dedicated electrical circuit. Connect the appliance to a grounded electrical outlet using an electric cable. The type of electrical plug is designed for mural (wall) connection. Verify that the voltage and frequency match the appliance's requirements (2250 Watts output).
5. Operating Instructions
Once installed and filled with water, the THERMOR Malicio 3 is ready for operation. The electric thermostat automatically regulates the water temperature.
5.1 Initial Startup
- Ensure the water heater tank is completely filled with water before switching on the power. Open a hot water tap to allow air to escape until water flows steadily.
- Connect the appliance to the main power supply.
- The water heater will begin heating. The 65-liter model typically heats water in approximately 2 hours and 52 minutes.
5.2 Temperature Adjustment
The control panel allows you to adjust the desired water temperature. Refer to Figure 4 for an illustration of the control panel.

Figure 4: Detailed view of the control panel, showing the water droplet indicator, plus/minus buttons for temperature adjustment, and an 'ECO+' mode button.
Use the '+' and '-' buttons to increase or decrease the set temperature. The illuminated segments around the water droplet icon indicate the current temperature setting or heating progress. The 'ECO+' mode optimizes energy consumption.
5.3 Energy Efficiency
This appliance is rated Class C for energy efficiency. Utilizing the 'ECO+' mode can further reduce energy consumption by optimizing heating cycles based on usage patterns.

Figure 5: EU Energy Label for the THERMOR water heater, indicating an energy efficiency class of B and an annual energy consumption of 1315 kWh. Note: Product description states Class C, while the label shows B. Please refer to the most current product documentation for accurate energy class information.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater. Always disconnect the power supply before performing any maintenance.
- Annual Inspection: It is recommended to have a qualified technician inspect the water heater annually.
- Safety Group Check: Periodically operate the safety group (pressure relief valve) to ensure it is not blocked. Follow the manufacturer's instructions for the safety group.
- Descaling: While steatite technology protects the heating element from direct contact with water and reduces limescale buildup on the element, the tank itself may still accumulate sediment over time. Depending on water hardness, periodic draining and cleaning of the tank may be necessary. This procedure should be performed by a qualified professional.
- Exterior Cleaning: Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
7. Troubleshooting
Before contacting customer service, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power supply Thermostat setting too low Heating element failure | Check circuit breaker/fuse Adjust thermostat to a higher setting Contact a qualified technician |
| Insufficient hot water | High hot water demand Thermostat setting too low Limescale buildup | Allow more time for reheating Increase thermostat setting Schedule professional descaling |
| Water leaking | Loose connections Faulty safety group Tank corrosion | Tighten connections Inspect and replace safety group if necessary Contact a qualified technician |
| Unusual noises | Sediment buildup Heating element issue | Schedule professional descaling Contact a qualified technician |
For problems not listed here or if solutions do not resolve the issue, please contact a qualified service technician.
