Wood pellet vacuum system
Using silo for 3-5 tonnes of woodpellets can be enough to load the tank once per year. It provide very good comfort of daily use and also for maintaince. We have one delivery per year what ensure constant quality of the fuel.
We have a lot of solution for such system: not only silos but also feeding system like long spiral screws or vacuum system fo pellets feeding.
