MCX3 electronic under-sink heater 3.5 kW / 230 V 15003

Compact and efficient flow heater for a sink

The MCX3 heater is a small, electronically controlled device designed for quick and efficient water heating under the sink. It is ideal for both domestic bathrooms and commercial facilities – public toilets, offices, or kitchen backrooms. Its compact dimensions allow for discreet installation, while advanced technology ensures comfortable use and energy savings.

Functionality and comfort of use

The MCX3 features an intuitive control panel with buttons, allowing you to set the maximum water temperature to 35°C, 38°C, or 45°C. This makes it easy to adjust the temperature to individual preferences without the need to mix with cold water. The electronics precisely regulate the heating power consumption, ensuring a stable water temperature and minimizing energy consumption. The set includes a special water flow regulator and a complete connection kit (tee and flexible hose), making installation to a standard angle valve easier.

Construction and durability

A key feature of the MCX3 heater is the efficient open stainless steel heating element system, which is particularly resistant to scale build-up – which translates to a longer device life even when using hard water. Metal water connection fittings increase mechanical strength, and the solid construction guarantees reliable operation for a long time. The device has a built-in electrical connection cable, which further simplifies installation. Low flow activation allows for efficient operation even with low water pressure in the installation.
