ATTACK ELECTRIC EXCELLENT technical features
Key control features and ways to integrate the boiler into home heating.
Controls
Control
Precise PID control manages heating and minimises overshoot above the set heating-water temperature. This helps the boiler run efficiently and maintain a comfortable indoor temperature.
ATTACK ELECTRIC EXCELLENT is suitable for forced-circulation heating systems with one to three heating elements rated at 7.5 kW. It can serve homes, buildings and shared spaces with heat loss up to 22.5 kW. Connect an indirectly heated tank to use it for domestic hot water as well.
