Piazzetta Wood Pellet stoves are designed to heat on demand so when a room or heating system reaches the correct temperature they switch off saving fuel and giving a more comfort and better economy than traditional wood stoves. The fuel is clean to use and leaves less than .5% ash to dispose off. The wood pellets used contain only saw dust and wood chippings that are bonded together by high pressure by the woods own natural chemical Lignin and as more trees are now planted than felled this fuel is truly sustainable. You can purchase them in easy to handle single bags or bulk loads and are normally of a guaranteed quality with very low moisture content, producing more heat (5kwh/kg) per kilo than using conventional logs at (2-4kw/kg.) No need to stockpile fuels years before you use it like you need to do with tradition wood stoves. Pellets can be purchased in convenient 10 or 15kg bags, or in bulk with waterproof bulk storage containers now available.
