Storage in underground tank

If there is no space in the building for a pellet store, there is also the option of an underground tank outside the building. This is dug under the ground and connected to the boiler by means of hoses and supplied with pellets, because these are conveyed by a suction probe / snail / mole located in the underground tank via the suction hose to the storage container. The filling takes place via the filling coupling attached to the underground tank. Different sizes of underground tanks are available depending on the manufacturer.
