Product Overview & Area of Application
The SELFA Smart Heater 1.5 kW heating element with app control is an electric heating element for water heating in suitable hot water tanks. It is suitable for open and closed enamelled storage tanks and, depending on the version, can also be used in stainless steel tanks.
The 1.5 kW power class is particularly interesting for smaller storage solutions, supplementary water heating, or controlled electric reheating. Operation is carried out directly on the display module or via the SELFA SMART HEATER app.
Technology & Equipment
The SELFA Smart Heater operates with a tubular heating element and is powered by a single-phase supply voltage of 230 V. The electronic thermostat features a wireless communication module and supports multiple operating modes for different usage situations.
Available modes include manual mode, ECO mode, SMART mode, schedule mode, away mode, and turbo/boost mode. In addition, safety functions such as frost protection and anti-legionella cycle run in the background.
Everyday Benefits
The app control enables flexible operation via Android and iOS mobile devices. The schedule mode is particularly practical, allowing water heating to be adapted to daily or weekly routines.
ECO mode keeps the water temperature constant at 55 °C, while SMART mode records usage behavior and subsequently adjusts water heating accordingly. Boost mode can be used for temporarily increased hot water demand.
System Integration & Compatibility
The heating element is intended for heating water in suitable storage tanks. Depending on the version, mounting threads G 5/4" or G 6/4" are provided for 1.5 kW.
When selecting, attention must be paid to the material version, thread, tank size, installation position, and suitability of the tank. For stainless steel tanks, only material versions suitable for this purpose may be used.

Installation
The heating element is screwed into a suitable sleeve of the storage tank. For the 1.5 kW version, the maximum immersion length is 305 mm; additionally, the non-heating zone of approx. 65 mm must be observed.
The heating element must be positioned completely below the water level. For horizontal installation, the permitted installation position must be observed according to the instructions so that the temperature evaluation functions correctly.
Notes
Before connecting to the 230 V socket, the tank must be filled with water and the heating element must be fully immersed. The socket must have a protective contact.
With hard water, limescale deposits should be removed regularly, as they impair heat transfer and can cause damage. Mechanical descaling is not intended.
