Boiler Tenko Smart 9_220 Grundfos


The electric boiler of the SMART Series TM Tenko is a perfect engineering solution that embodies reliability and comfort standards.
The advantages are a housing convenient for installation and maintenance, a frequency-controlled circulation pump, copper heating elements blocks, a hydraulic group of European production. A special advantage is the 5'' color touchscreen display making it intuitive to enter parameters and monitor boiler working.
The built-in Wi-Fi module allows connecting the boiler to your home Wi-Fi access point, so you can:
- Control the boiler and monitor its status from anywhere in the world via a special application or WEB-interface;
- Synchronize the boiler time with the real time server;
- Receive the latest software updates. Boilers’ power range is 6, 9, 12, 15, 18, 21, 24, 30, 36 kW
Boilers with a 6 and 9 kW capacity are intended for supply voltages of 230V and 400V, and ones with a capacity of 12 kW and above may cover a supply voltage of 400V.
To ensure a high safety level, the following background functions have been added to the boiler control system: frost protection (AF5), selectivity, modulation, residual current device (RCD) function, overheating protection.
