Control the water temperature in your home with the SELFA SMART HEATER heating element using your phone

With the growing interest in smart home devices, SELFA announces today the launch of its latest product – SELFA SMART HEATER. Water heater elements controlled by an app on your phone via Wi-Fi. This new technology promises to revolutionize the way we control the temperature in our homes.

About the product:

The new heater, named SELFA SMART HEATER, allows users to remotely manage the water temperature in boilers or buffers using a dedicated smartphone app. This means you can adjust the heat even when you’re away from home, contributing not only to convenience but also energy savings.

Smart functions:

One of the key features of this innovative heater is its ability to learn. Using artificial intelligence technology, SELFA SMART HEATER analyzes user habits and adjusts temperature settings, providing optimal and energy-efficient use of hot water. By learning when we use water, it doesn’t heat it when we’re, for example, at work. This realistically contributes to energy savings.

Health and safety:

For us, health and safety are also paramount, which is why the SELFA SMART HEATER is equipped with sensors and a processor that monitors the water temperature even when the heater is off (in standby mode). It prevents water from freezing in the tank and stops the growth of the dangerous Legionella bacteria by heating the tank to a temperature that kills these bacteria. If you prefer a lower temperature in the tank on a daily basis (below 50°C), SELFA SMART HEATER will take care of your safety by automatically heating it to the appropriate temperature.

For everyone who wants to increase comfort in their homes while also caring for energy efficiency, the SELFA SMART HEATER is an exceptional and suitable product.

Immersion Heaters with Thermostat and Insulated Heating Element

Immersion heaters are electrical devices designed for heating water in both open and closed tanks. These heaters can only be installed in systems where they remain submerged below the water level at all times.

The insulation of heating elements is achieved by mounting them in a flange that is isolated from the head, which is entirely made of brass, including the threaded connection. This insulation is used to eliminate the galvanic connection between the heating elements and the tank.

When a galvanic connection occurs between a metal with a negative potential (the material of the tank's casing) and a noble metal with a positive potential (the material of the heater’s heating element), a galvanic cell is formed. This reaction accelerates the dissolution of the magnesium anode, causing magnesium deposits on the heating elements while the tank casing undergoes corrosion.

This solution optimally protects both the heating element of the heater and the tank from accelerated electrochemical corrosion while maintaining the cathodic protection of the tank. Additionally, it extends the lifespan of the magnesium anode.

ZGTi / ZGT type heating elements are designed for heating hot water in open and closed containers made of enameled or stainless steel. They have been designed to work in conjunction with the OHMPILOT controller in a power range from 3kW to 9kW.

• The automatic shutdown of the heating unit is controlled by the thermostat, and in case of its malfunction, an involuntary temperature limiter will activate at a water temperature of 98 (0/-8)°C.” (Regulacja temperatury: +7,5±6°C do +75±3°C.
• The anti-freeze function is designed to maintain the water temperature in the tank at +7.5 ± 6 ºC.
• The green light indicates that the heating element is connected to the power supply. The red light signals the flow of current through the heating element.
• Ingress Protection rating: IP44
• Threaded connection: G 1½”
• Maximum allowable pressure in the tank: 10 bar
• The insulation of the heating elements is achieved by mounting them in a ceramic insulator separated from the head made of brass or stainless steel, including the threaded part.
• A grounding resistor with a carefully selected resistance has been used for the partial connection of the heating elements to the tank, which integrates these elements into the cathodic anti-corrosion protection of the tank. This solution optimally protects the electric heating element in an enameled tank from accelerated electrochemical corrosion while maintaining the cathodic protection of the tank and the lifespan of the magnesium anode.
