ATTACK Electric Excellent 24 kW (nominal heat output 22.5 kW)

Product description:
The ATTACK Electric Excellent 24 is a wall-mounted electric boiler for forced-circulation heating systems with higher heating loads. Its PID control precisely switches between heating stages and maintains a constant flow temperature. Remote control via GSM/smartphone is available as an option. Domestic hot water can be generated via an external storage tank and a 3-way valve (TUV operation).

Highlights:

• 99% efficiency, quiet operation, display & Diagnostic memory

• Protective functions including frost/overheating/pressure loss protection

• Compact design despite high performance
