Experience reports with pellet heating

Hello everyone,

does anyone have experience with pellet heating systems? I am interested in acquisition and running costs and, of course, practical experiences in handling.
Thanks in advance.

At my mother-in-law's workplace (Gemeindehaus), they tore out the pellet heating system that was only a few years old because the feed screw kept getting clogged.

I would not buy pellets because of the CO2 balance. The idea of "sensibly using wood waste from the region" is hardly left; it comes from somewhere else, from trees cut down specifically for this purpose. Better to use wood chips or log boilers.

In our newly built kindergarten, you have installed one for whatever reason. So far, I have heard that there are constant problems and everyone complains because that thing smells so bad.. My parents also had one (old oil heating replaced). There were quite a few teething problems, but I believe they were more due to the interaction (or lack of interaction) with the solar thermal system.

I can give you practical experience in handling. I dealt with it professionally for several years. Stay away, the pellet boilers are relatively complicated in design, have many mechanically moving parts that tend to break, spare parts are relatively expensive, and many service technicians are not very familiar with them. In my own house, I could have installed something like that, but I preferred not to...

Thank you very much in advance for the answers. The emerging trend is clear.

Hello

In the new building 2001 a pellet stove with water circuit Wear repairs such as glow igniter and combustion bowl as well as a circuit board after overvoltage In the new building 2015 again one so far no repairs In the current building a pellet boiler is waiting to be installed Of various (about 30) systems installed at customers, there have been no serious problems except for two new developments.

I consider the idea that only pellets from "bad" wood exist to be a rumor.
