- Oliver: you If you a pallet heating, you usually yourself two questions. First, how big does the system have be? And then, where should all the pallets go? The good news first, the pallet heating often much more space than an old oil heating. In many houses, the former oil tank can as a pallet warehouse. And when to dimensioning, it's not about as much power as On contrary, an too large system often less efficiently. Such a rough rule There are about 50 watts of power per square meter of space. So house with 150 square meters then about 7.5 kilowatts of heating power. Modern family houses often in an between 6 and 15 kilowatts. And how much actually needed depends heavily on the insulation standard, the windows and the general condition of the building. The exact layout is then out by professionals via a heating load calculation according to the DIN EN12831. The often forgotten space eater is the pellet storage. The heating system itself is not the problem. The actual space needs to by the fuel supply that you need. For a typical family house, should a 6-9 cubic meters. This often to 8 square meters of space. For orientation, 1 ton of pellets requires 1.2-1.5 cubic meters storage space. 1 kilogram of pellets delivers about 5 kilowatt hours of energy. Such average family house needs 4-6 tons of pallets per year. Many owners are surprised how compact such pallet storage can For this annual supply, i.e. a average family house, space with a 2x3 meter base area This corresponds to the size of a small basement space. And even if the heating room itself too small, the storage does have to right next to the cauldron. There are modern support systems that can also pallets over a distance of up to 20-25 meters. without This allows you to garage, side buildings or separate basement rooms as a warehouse. But don't forget the buffer storage, because next the cauldron and pallet storage, a buffer storage is the system. As reference, 30 to 50 liters storage volume per kilowatt cauldron power With a 10 kW system, would be 300 to 500 liters. The storage ensures that the pallet heating can as long and efficiently in optimal power range as So is really a misunderstanding with pellet heating that you huge basement areas for As I said, you need a storage space of 6 to 8 m² That should be sufficient. The neck load itself is often only between 6 and 15 kW. And if you former oil tank room or a free basement space available, it already the most important prerequisite for pellet heating. And that is why pellet heating, especially in existing buildings, often an interesting alternative when the heat pump should optimally or should exactly on this biomass fuel. This is very interesting If you want to calculate how to the old oil heater, whether a heat pump is better suited for or perhaps a pallet heater, you are welcome to contact More information can be in the show notes.
