I bought a year ago in an apartment to replace the old Italian brand (I will not name), which for several years of "work" brought us all the brains. I will say right away: I read the reviews and chose for a long time, because it is not an option to exercise with the boiler stably once a month. They read a lot of different things about Wissmanns, and nasty things, like F2, F5 errors popping up among people or the boilers themselves go out ... I personally traveled to service centers of several companies and got to the bottom of the specialists. And still bought this dual-circuit Vitopend 100.
I can definitely say: the boiler is good, it eats gas much less than the previous one, the automation works clearly, I have not yet issued any errors. The only thing is that hot water with a slight delay, 3-5 seconds, and when someone washes a second tap it is better not to turn it on, the temperature in the shower may drop. The rest works like a clock, hung in the kitchen, turned on and forgot about him if he had not rustled)))
And an important addition at the end. From the experience of reading reviews and my own use of the boiler, I can conclude: the technique is complex, smart, and if it is set up by a curved-handed installer, then you get tormented with Wissmann. Therefore, a tip: if you are buying a Vitopend 100, look for professional installers. Better pay more for the installation, so that later it is guaranteed not to have problems with the boiler.
pros
Reliable - turned on and forgot
Minuses
Noisy more than we would like; hot water with a delay of 3-5 seconds.
