Outdated Product
Wall-mounted Italian double-circuit gas boiler of medium power with a combined (bithermic) heat exchanger and a turbocharged combustion chamber with forced smoke removal. It is positioned as a product of the basic price category, which can simultaneously provide heating and hot water supply to a cottage, a multi-room city apartment, as well as office, commercial or communal premises. Thanks to a significant useful thermal power of 24 kW, it is able to serve areas of up to 144 m². The closed combustion chamber of the BAXI Main 5 24 F boiler does not require the creation of a complex chimney system and simplifies the installation of the device in residential areas. The improved bithermic heat exchanger made of copper is distinguished by the oval shape of the hot water heating channels and a...special coating against salt deposits. The boiler is well adapted to Ukrainian heating systems and works great with water of medium hardness. A convenient electronic control system with an LCD screen makes it easy to control and manage the main parameters of the boiler. Due to the two temperature ranges of the heat carrier in the heating circuit, it can be used in underfloor heating systems. Works with a remote room temperature sensor and a programmer (purchased separately). It is completed with a corner and a coaxial pipe 60/100 mm.

good model, I liked it.
20 April 2021 
we've been using this boiler model for 3 years (we bought an apartment from the developer with individual heating, and the boiler was included in the price) so far, there are no complaints, the main thing is not to forget to switch between "summer/winter" modes.
simple and reliable

Good Italian boiler at a nice price
28 February 2016 
Good heat output and economical gas consumption. Savings are obtained due to the fact that the burner is modulated and the intensity of combustion varies depending on the operating mode of the boiler. It regulates the automatic burner and it is excellent in this boiler. There is a smooth ignition and an advanced system for regulating the thrust force according to the flue gas parameters. Automation can identify and diagnose possible causes of incomplete gas combustion. It also protects the boiler from freezing, high pressure, loss of pressure and other troubles. It heats perfectly, there is also enough hot water for the whole family. At the same time, the boiler itself is quite small and takes up a minimum of space. The new design of the heat exchanger is bithermic. It was this design with coaxial heating and hot water supply channels that made it possible to reduce the size of the boiler and make its price affordable. The boiler is well adapted to work in our country. He is not afraid of drops in gas pressure and continues to work with fairly strong power surges. It works quietly for me without an additional electrical stabilizer. Good price, competitive. I would say that for an Italian-assembled boiler, the best is not to be desired. Most European boilers of similar capacity are noticeably more expensive.
When you first turned it on, it seemed to start, but immediately knocked out an incorrect start error. It turned out that the matter was in the phase wire in the electrical network and you just need to swap the pins of the plug in the outlet.
use BAXI Main 5 24 F month or more
if it breaks, I won’t repair it, but I’ll install another one.

it's probably better to buy another one
compact
a couple of months after installation, the hot water stopped flowing. I had to change the heat exchanger. Moreover, the service center refused to replace it under warranty, citing bad water. Although, in my understanding, no matter what kind of water there was, the heat exchanger would not clog so quickly. But I didn’t want to spoil my nerves, but I wanted warmth in the house. Now it seems to have been working for 8 months without any problems.
