Vertical/Horizontal Electric Water Heater with WiFi Thermor Onix Connect 120

The Thermor Onix Connect 120, reference 261143, is a multiposition electric water heater with high capacity and an extra-slim design for domestic hot water production. It features WiFi connectivity, double vitrified tank, double ceramic heating element and smart electronic control, offering a solution designed to combine comfort, energy savings and flexible installation. Although its commercial name is Onix Connect 120, Thermor specifies for this model a technical capacity of 100 liters.

Its flat format provides high storage capacity while reducing the depth of the unit compared with conventional cylindrical water heaters. In addition, it can be installed both vertically and horizontally, making it easy to integrate into bathrooms, utility rooms, technical rooms and other spaces intended for DHW production.

WiFi connectivity and control via Cozytouch

The Thermor Onix Connect 120 includes WiFi connectivity to manage the water heater through the free Cozytouch app. From the app, it is possible to check water and electricity consumption and schedule the unit’s operating times, enabling more precise management of domestic hot water.

The water heater also features an integrated touch digital display, from which its different operating modes can be selected and the main settings can be adjusted directly on the unit.

Four smart control modes

The Onix Connect offers four control modes: Eco+, Manual, Turbo and Absence, allowing hot water production to be adapted to the regular or occasional needs of each home.

• Eco+: learns the user’s usage habits to adapt hot water production and help reduce energy consumption.
• Manual: allows the water heater to be managed according to the user’s preferences.
• Turbo: designed for situations with higher occasional hot water demand.
• Absence: intended for periods when normal operation of the unit is not required.

Double vitrified tank and double ceramic heating element

The Thermor Onix Connect 120 uses a double vitrified tank, a configuration that combines high storage capacity with a reduced-depth design.

Heating is carried out by a double sheathed ceramic heating element with low loading rate. This technology prevents the heating element from being in direct contact with the water and is part of the durability solutions used by Thermor in the Onix Connect range.

The protection of the tank is completed with a double magnesium anode and high-density thermal insulation, designed to reduce heat losses from the stored water.

BriseJet system to optimize stratification

The unit incorporates the BriseJet system, developed to promote proper water stratification inside the tank. This technology helps limit mixing between incoming cold water and stored hot water, allowing more efficient use of the available volume.

For reference 261143, Thermor indicates a heating time of 4 hours and 25 minutes to 65 °C with a temperature increase of 50 °C.

Vertical or horizontal installation

One of the main advantages of the Thermor Onix Connect 120 electric water heater is its multiposition design. The unit can be installed both vertically and horizontally, making it easier to adapt to different configurations and available spaces.

When installed horizontally, Thermor specifies that the hydraulic connections must be on the left. In addition, the water heater comes as standard with a mounting plate to facilitate wall installation.

Its extra-slim format has a depth of 320 mm, a particularly useful feature for installations where reducing the unit’s footprint is important without giving up high DHW capacity.

Energy efficiency and performance

The Thermor Onix Connect 120 has energy efficiency class B and load profile M. It operates with a power rating of 2250/1000 W and a 230 V power supply.

The combination of WiFi connectivity, Eco+ function, high-density thermal insulation and BriseJet system allows hot water production to be adapted to usage habits and provides greater control over the water heater’s operation.
