ATTACK Electric Excellent electric boiler – environmentally friendly heating solution

Easy-to-use multi-purpose LCD display

The ATTACK Electric Excellent electric kettle impresses with its clearly structured, multi-purpose LCD display. It clearly displays all relevant information such as temperature, operating status, and error messages.

The intuitive menu navigation allows for quick adjustment of the settings, so that even laypeople can operate the boiler easily and without prior knowledge.

Control via room thermostat and smartphone

An integrated interface allows control via an external room thermostat, allowing you to precisely and energy-efficiently regulate your desired temperature.

The Electric Excellent also offers remote control via smartphone. Temperature and time settings can be conveniently adjusted while on the go or from the comfort of your sofa at home.

Precise PID control for efficient operation

Thanks to linear PID control, the electric boiler maintains the heating water temperature at the set target. Fluctuations are minimized, significantly reducing energy consumption.

This automatic control makes the Electric Excellent particularly economical and contributes to a longer service life of the components.

Versatile use in residential buildings

The electric boiler is suitable for heating systems with 1–3 radiators up to 7.5 kW and can heat domestic water in single-family homes and common areas with heat losses of up to 22.5 kW.

For hot water preparation, the boiler can be easily connected to an indirectly heated storage tank and reliably provides comfortable shower or bath water.

Excellent efficiency and quiet operation

With an efficiency of up to 99%, the electric boiler is extremely energy-efficient. Almost all of the electrical energy supplied is converted into heat.

Another advantage is its silent operation: With no combustion noise, the boiler is perfect for living rooms, offices, or other rooms with increased comfort requirements.

Comprehensive protection functions

The ATTACK Electric Excellent features integrated frost protection and an overheating safety device that reliably protect the boiler and connected underfloor heating systems.

There is also a safety function to prevent pressure loss in the heating system, so that possible faults are detected and reported at an early stage.

Equithermal control for automatic comfort

An additional equithermal controller can be connected to automatically adjust the flow temperature to the outside temperature, ensuring the optimal room temperature is always maintained.

This control method increases comfort and saves running costs, as the boiler only provides as much power as is actually needed.
