ATTACK Electric Excellent electric boiler – environmentally friendly heating solution

Powerful multi-purpose LCD display

The ATTACK Electric Excellent electric kettle is equipped with a clearly structured multi-purpose LCD display that clearly shows all relevant information such as temperature values, operating status and error messages.

The user-friendly menu navigation allows for quick adjustment of the settings directly on the device, so that even laypeople can operate the boiler safely without prior knowledge.

Flexible control via room thermostat and smartphone

An integrated interface allows connection to external room thermostats, which allow you to regulate the desired temperature precisely and in an energy-efficient manner.

In addition, the electric boiler offers remote control via smartphone app, so you can conveniently adjust heating times and temperatures while on the go or from the comfort of your sofa at home.

Precise PID control for high efficiency

The linear PID control of the Electric Excellent ensures constant heating water temperatures at the set target value and minimizes fluctuations.

This automatic temperature control significantly reduces energy consumption and extends the service life of the components.

Versatile use in residential buildings

The electric boiler is ideal for heating systems with one to three radiators up to 7.5 kW and can also heat domestic water in single-family homes or common areas with up to 22.5 kW heat output.

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

Excellent efficiency and quiet operation

With an efficiency of up to 99%, the electric boiler converts almost all of the supplied electrical energy into heat and is therefore extremely energy-efficient.

The silent operation without combustion noise makes the boiler the ideal solution for living rooms, offices and other environments with high comfort requirements.

Comprehensive protection functions

The ATTACK Electric Excellent features integrated frost protection and a reliable overheating protection device that protects both the boiler and connected underfloor heating systems.

An additional safety function monitors the system pressure and detects pressure losses in the heating system at an early stage in order to report faults in a timely manner.

Automatic equitherm control

By connecting an optional equitherm controller, the flow temperature automatically adjusts to the outside temperature, optimizing heating comfort.

This intelligent control ensures consistently comfortable room temperatures while simultaneously reducing running costs by only providing the power actually needed.
