A gas boiler by Ferroli: problems here, there and not only!

There are a few reasons why I regret buying a Ferroli gas-fired condensing boiler BLUEHELIX PRO 25C. The video shows first how the boiler’s poor programming makes it start at 2/3 of max power (two flames in the rightmost part on the LCD) in the heating mode (the 15 sec of the video clip) , run for a minute and then shut. The heating temperature is set at 43 C. At 1 min and 56 sec you will see that the boiler starts at 1/3 of max power (one flame in the rightmost part on the LCD) in the hot water mode. The video proves that the boiler’s burner can start at 1/3 max power, but it never does so in the heating mode, thus speeding up wear and tear of the boiler’s parts (e.g. this shortens the gas valve's life more than two times!!!). This is the main problem with the boiler. I have found no way to fix it. There is a web-link in the description part of the video with more details. Main observation # 1: The boiler is of a sound design (except burner being too powerful in the hot water mode) and has high-quality parts, but has a number of flaws that are too hard to fix without changing the boiler's brain.

Main observation # 2: the Ferroli customer service is instructed neither to hear you, nor to accept any fault on the brand's part, however hard you try. The main office in Italy did not reply to my enquiry. So don't waste your time, there are better things to do. Besides the main issue, the boiler has such problems: 1. As just mentioned, the burner is too powerful in the hot water mode to allow any economic use of water. 2. When a room thermostat turns off the boiler, the letter's pump stops immediately without a delay to let just heated water to get out of the boiler.

3. It has a few instances of poor workmanship, e.g. clogged at the factory pump and poorly soldered pipes allowing for oxidation. 4. A syphon of the condenser is too small and hard to put back without a leak. Now the boiler starts at 1/3 of max power (one flame in the rightmost part on the LCD) in the hot water mode There is a web-link in the description part of the video with more details. Thanx for watching!.
