Product Overview & Application Area
The heating element with app 2.0 kW SELFA Smart Heater is an electric screw-in heating element for water heating in suitable hot water tanks. It is intended for open and closed enamelled storage tanks and, depending on the material version, is also suitable for stainless steel tanks.
The 2.0 kW version is intended for storage solutions where hot water is to be generated electrically, reheated, or supported on demand. According to the type table, this power class is intended for a minimum tank volume of 80 litres.
Technology & Equipment
The SELFA Smart Heater operates with a tubular heating element and is powered by a single-phase voltage of 230 V. The electronic thermostat has a wireless communication module and can be operated directly on the display module or via the SELFA SMART HEATER app.
The equipment includes several operating modes for different usage situations. These include manual mode, ECO mode, SMART mode, schedule mode, absence mode, and turbo/boost mode. In addition, the anti-legionella function and frost protection work as safety programmes in the background.
Everyday Benefits
App control enables convenient operation via Android and iOS mobile devices. This allows the operating mode, temperature, and time programmes to be flexibly adapted to the actual hot water demand.
In ECO mode, the water temperature is constantly maintained at 55 °C. SMART mode records usage behaviour and subsequently uses this data for more demand-oriented hot water preparation. Boost mode can be used when a higher hot water temperature is required at short notice.
System Integration & Compatibility
The heating element is screwed into a suitable socket of the storage tank. Depending on the version, mounting threads G 5/4" or G 6/4" are available.
When selecting, the thread size, material version, tank size, installation position, and tank material must be considered. Copper versions are not intended for stainless steel tanks; for certain stainless steel or titanium anode systems, suitable stainless steel or Incoloy versions must be selected.

Installation
The heating element is screwed into the designated connection of the storage tank. For the 2.0 kW version, the maximum immersion length is 305 mm; in addition, the non-heating zone of approx. 65 mm must be taken into account.
The heating element must be positioned completely below the water level. For horizontal installation, the permitted orientation must be observed according to the instructions so that the temperature evaluation can work correctly.
Notes
Before connecting to the 230 V socket, the tank must be filled with water and the heating element must be completely submerged in the water. The socket must have a protective earth contact.
With hard water, limescale deposits should be removed regularly with suitable agents, as deposits can impair heat transfer and cause damage. Mechanical descaling is not intended.
