High usage comfort
ATTACK ELECTRIC EXCELLENT is an electric boiler that can heat a building with lower energy demand in places without a gas connection. You can also use the boiler as a backup source for heating systems – for example, for solid fuel boilers. The boiler offers guaranteed comfort in the form of simple operation and reliable operation.
Suitable for every type of house, apartment, or recreational object
ATTACK ELECTRIC EXCELLENT is an ideal solution for undemanding systems, even smaller recreational objects with heat losses up to 7.5 kW. It provides the comfort of a gas boiler and is also suitable for underfloor heating.
Electric boiler connection
The connection of an electric boiler is simple. The connection requires a 380 V power supply. With an electric boiler, you ensure ecological heating with minimal environmental impact wherever other heating sources cannot be used. A combination of an electric boiler with a solar system, which can provide up to 70% of hot water for a household during the year, is also suitable for an electric boiler.
Electric boiler functions
It includes a built-in automatic air release function. Other functions that protect it from unexpected influences are: anti-frost, anti-overheating, and anti-pressure loss. If you also need to heat hot water, you will have no problem with this boiler and you can easily connect a DHW heating cylinder to it.
Simple operation
The built-in LCD display facilitates operation and displays all the necessary information. The display shows an indication of faults diagnosed by the system. You can control the boiler via a room thermostat, but you will experience much greater comfort if you use a mobile phone for control.
The heating process is controlled by a control unit with precise PID regulation, which ensures highly economical operation by minimizing heating water temperature overshoots above the set temperature. You can use the boiler mainly for heating in heating systems (1 – 3 heating elements with 7.5 kW power) with forced water circulation and DHW heating in family houses, buildings, and common spaces with heat losses up to 22.5 kW. You can also use the Electric Excellent boiler for heating hot water by connecting an indirectly heated cylinder.
