4. Installation and Setup
Installation should only be performed by a qualified professional. Refer to the detailed installation guide provided with the product for specific instructions and diagrams.
4.1 Mounting the Water Heater
- Choose a suitable vertical wall location capable of supporting the full weight of the water heater when filled with water (approx. 156 kg for 120L model).
- Mark the drilling points for the wall brackets according to the provided template.
- Drill holes and securely fasten the mounting brackets to the wall.
- Carefully lift and hang the water heater onto the installed brackets. Ensure it is level and securely seated.
4.2 Plumbing Connections
- Connect the cold water inlet to the designated port, typically marked with blue. Install a shut-off valve and a pressure relief valve.
- Connect the hot water outlet to the designated port, typically marked with red.
- Ensure all connections are watertight.
- Fill the tank with water before connecting to power. Open a hot water tap to allow air to escape until water flows steadily.
4.3 Electrical Connection
- Ensure the main power supply is OFF at the circuit breaker.
- Connect the water heater to a dedicated electrical circuit with appropriate overcurrent protection, as specified in the product's technical data.
- Follow the wiring diagram provided in the full installation manual.
- Once all connections are secure and the tank is filled, restore power.
4.4 Smart Connectivity Setup

- Follow the in-app instructions to create an account and pair your Malicio 3 water heater with your home Wi-Fi network.
- The Wi-Fi indicator on the control panel will confirm a successful connection.
5. Operating Instructions
Your Thermor Malicio 3 water heater offers various modes and settings for optimal comfort and energy efficiency.
5.1 Initial Start-up
After installation and power connection, the water heater will begin heating water to its default temperature setting. This may take several hours for the first full tank.
5.2 Adjusting Temperature
- Use the + and - buttons on the control panel to set your desired water temperature.
- Alternatively, adjust the temperature remotely via the Thermor Connect app.
5.3 Operating Modes
- Smart/Auto Mode: The water heater learns your hot water consumption patterns and adjusts heating cycles automatically to optimize energy use while ensuring hot water availability. This is the recommended default mode.
- ECO+ Mode: Activates an enhanced energy-saving profile, potentially reducing hot water availability during off-peak times. Press the ECO+ button on the control panel or select via the app.
- Boost Mode: For situations requiring extra hot water quickly (e.g., guests), activate Boost mode. This initiates a rapid heating cycle. Deactivates automatically after a set period or when the tank is fully heated.
- Absence Mode: If you are away for an extended period, activate Absence mode via the app to maintain a minimal temperature, preventing freezing and saving energy.
5.4 Monitoring via App
The Thermor Connect app allows you to:
- View current hot water availability.
- Adjust temperature settings.
- Switch between operating modes.
- Monitor energy consumption.
- Receive notifications and alerts.
6. Maintenance
Regular maintenance ensures the longevity and efficiency of your water heater. Always disconnect power before performing any maintenance.
6.1 Annual Inspection
It is recommended to have your water heater inspected annually by a qualified professional. This inspection should include:
- Checking the pressure relief valve for proper operation.
- Inspecting electrical connections for tightness and corrosion.
- Checking for any signs of leaks around plumbing connections.
- Inspecting the anode rod (if applicable) for depletion and replacing if necessary to prevent tank corrosion.
6.2 Descaling (Hard Water Areas)
In areas with hard water, mineral deposits (limescale) can accumulate on the heating element and inside the tank, reducing efficiency. Descaling should be performed periodically by a professional. The frequency depends on water hardness.
6.3 Cleaning
Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
