Model overview based on user reviews  
The Beretta CIAO 24 CSI 23.9 kW gas boiler receives mixed reviews from users. Some praise its affordable price and ease of operation, noting that it can work reliably for several years, with one user reporting ten years of flawless performance. However, many users highlight significant issues, particularly with the heat exchanger, which tends to leak or clog, leading to expensive repairs. Several users experienced problems after a few years, such as pressure fluctuations and noisy operation. Despite these issues, some users find it a good value for the price, especially if proper maintenance like installing a pressure reducing valve and anti-scale filter is performed. Overall, while it can be a cost-effective solution, potential buyers should be aware of the maintenance needs and possible long-term costs.

Hello! I purchased the Beretta CITY 24 CSI Boiler No. F4NG2152162 in 2012. It only worked in heating mode for two heating seasons. The result is that the heat exchanger leaks, and the expansion tank does not work (problems started after the first season). The cost of the heat exchanger and the expansion is more than half the cost of a new boiler. The price-quality ratio is genuinely surprising. I'm attaching a photo of the heat exchanger. They should just write that the boiler is disposable for one season.
use Beretta CIAO 24 CSI month or more i recommend it don't buy
i worked well for 6 years, and then what? 2 weeks left until the start of the heating season

it might be easier to change the boiler to a new, modern ciao 24 csi boiler with the letter N. I just don’t know if a direct replacement is possible
i have been using a Ciao 24 csi boiler since May 2004. Before this, there was no hot water in the house for 7 years. After installing the boiler, I saw the happy face of my wife and children. I survived the cold winter of 2006 in Alchevsk - the whole family lived in comfortable conditions.
In the last 2 months (boiler ciao 24 csi) - the water pressure increases to 3 atm. instead of the normal 1.5-2.0. Checked - it seems that the cold water three-way valve with article number R-2265 is leaking. Where to find it or how to order it?

In principle, the boiler is decent

The pressure in the boiler fluctuates, then increases, then decreases. When hot water is turned on, the pressure drops from 1.6 to 1.0 and the temperature drops from 40 to 20.
