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 and to the boiler by hoses pellets supplied, because these are transported by a suction probe / snail / mole located in the underground tank via the suction hose to the storage tank. The filling takes place via the filling coupling attached to the underground tank. Different sizes of underground tanks are available depending on the manufacturer.
