ATTACK Electric Excellent electric boiler – Environmentally friendly heating solution

Clear, multi-purpose LCD display

The ATTACK Electric Excellent electric boiler features a clearly structured LCD display that shows all important information such as current temperature, operating status, and any error messages. Thanks to the intuitive menu navigation, settings such as setpoint temperature and operating times can be adjusted quickly and easily.

Even without prior technical knowledge, you can operate the boiler with just a few simple steps and always keep track of your heating output.

Control via room thermostat and smartphone

The electric boiler can be conveniently connected to an external room thermostat via an integrated interface, allowing you to precisely set the desired temperature. This ensures consistent comfort in your rooms.

Additionally, the optional remote control via smartphone allows for convenient control of temperature and time programs – whether on the go or comfortably on the sofa.

Precise PID control for efficient operation

The advanced PID control keeps the heating water temperature constant at the setpoint, minimizing temperature fluctuations. This ensures even heat distribution and noticeably reduces energy consumption.

This automatic control reduces the stress on the components, which sustainably increases the lifespan of the boiler.

Versatile use in residential buildings

Whether for a single-family home or a small multi-family home – the electric boiler is suitable for 1–3 heating circuits up to a total heating output of 7.5 kW and can also reliably heat domestic hot water in combination with an indirectly heated hot water storage tank.

Even in communal areas or bathrooms with increased heating requirements up to 22.5 kW, the ATTACK Electric Excellent delivers comfortable temperatures for showers and baths.

Excellent efficiency and quiet operation

With an efficiency of up to 99%, the electric boiler utilizes almost all of the supplied energy and operates extremely economically. This conserves resources and reduces your operating costs.

Thanks to its silent operation without combustion noise, the boiler can be installed discreetly in living rooms, offices or wellness areas.

Comprehensive protection functions

The ATTACK Electric Excellent comes standard with frost protection and overheat protection, reliably safeguarding the boiler and connected heating circuits from damage. Additionally, a pressure monitoring system warns of any potential pressure drop in the system.

This allows malfunctions to be detected early and costly failures to be avoided.

Equitherm control for automatic comfort

An external Equitherm controller automatically adjusts the flow temperature to the outside temperature, ensuring a consistently comfortable indoor climate. This means the boiler only delivers the required output, saving on ongoing energy costs.

This adaptive control optimizes the efficiency of your heating system and increases everyday living comfort.
