Make an Inquiry

The most efficient on the market Italtherm

Modulation ratio > 1:20

City Top is the only wall hung gas boiler in the world with a modulation range higher than 1:20.

This allows:

  • a decrease in switching on and off
  • silent operation
  • reduced gas consumption and polluting emissions
  • a longer life of the appliance

City Top is the most efficient and flexible boiler on the market, able to adapt to the actual heat requirement of the system.

It checks, adjusts, fits

Italtherm has developed the ICS (Intelligent Combustion System). Thanks to this system, City Top can be considered an intelligent boiler, checking, regulating and adapting itself independently.

The ICS controls combustion values and regulates gas flow in order to get always the correct air/gas ratio, thus obtaining:

  • a reduction of gas consumption
  • lower CO/CO2 emissions
  • a shorter installation time (there are no manual adjustments to be made).

Silent and safe

City Top ensures the highest safety standards in the market thanks to the double sealing of the combustion group.

The double sealed chamber, further increasing the level of safety, improves the acoustic performance of City Top inside the home. City Top has thus reached the lowest noise levels in the market, to the benefit of comfort.
