Outdated Product
A wall-mounted gas boiler designed for heating and hot water for domestic needs. This device can heat a house with an area of up to 226 m². The design of the Italtherm CITY CLASS 30 F boiler uses high-quality units and components. The primary heat exchanger (for heating) is made of copper, the secondary (for DHW) is made of stainless steel, and the hydraulic group is made of brass. A 3-speed Grundfos pump is responsible for the circulation of water in the heating circuit. The intelligent control system flexibly controls the modulating burner to achieve maximum efficiency and economy across the entire power range (from 10.2 kW to 28.2 kW). When operating at full capacity, the boiler consumes up to 3.17 m³ of gas per hour. The equipment has a set of sensors and safety systems that provide pr...otection against flame extinction, overheating of the liquid in the circuit, drop in gas pressure in the main line, lack of draft, freezing of the coolant, etc.

normal model, nothing special
28 April 2019 
All parts are copper or brass
It works very noisily, vibration is felt.. Replaced the air fan, noise and vibration decreased slightly
just bought Italtherm CITY CLASS 25 F  i recommend it don't buy
The boiler is simple and reliable. I recommend

Copper heat exchanger, brass hydraulic group, easy to maintain, all components are of high quality, European. Convenient settings, digital knobs, not mechanics as some reviews say. All intervals can be set in those menus, if it turns on often, depending on the volume and length of the coolant, you can set the heating operation delay as you like. Water heating is good, smooth, there are no temperature changes, enough for 2 points.
A little noisy. With factory settings, the heating turns on (clocks) every minute.
use Italtherm CITY CLASS 25 F few months
Terrible device

You won’t sleep with him, or you’ll get used to such a stupid mode of operation
Mechanical twisters
Loud, minimum temperature lights up and turns off every 2 minutes
use Italtherm CITY CLASS 25 F more than year
