The budget for a new heating system in an old building is often not sufficient for a heat pump, as the investment is associated with several follow-up investments. If radiators need to be replaced, or the house needs to be insulated, or perhaps a PV system needs to be installed so that the heat pump can work efficiently, the costs increase considerably and may no longer be profitable in many existing homes in the long run. Pellet boilers can be integrated into an existing heating system more simply and economically, which keeps the purchase costs moderate. Our modern boilers are very efficient and provide even heat output regardless of outdoor temperatures. It is advisable to speak with one of our sales consultants to determine the best option for your home.\u003c\/p\u003e\n\u003ch4\u003eA pellet boiler works similarly to a gas or oil boiler, but with wood pellets as fuel.\u003c\/h4\u003e\n\u003cp\u003eThe pellets are fed into the burner by means of a screw conveyor, where they are burned to generate heat. This heat is then passed through a heat exchanger that warms the water in the heating system. The heated water is then distributed through pipes to the radiators or underfloor heating systems in the house to heat the rooms. An electronic control system ensures that the fuel is transported to the burner in sufficient quantity and that the combustion air supply is automatically regulated to maximize efficiency. \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEnvironmental friendliness: Wood pellets are a renewable fuel and have a low CO2 footprint compared to fossil fuels such as oil or gas.\u003c\/li\u003e\n\u003cli\u003eEfficiency: A pellet boiler is very efficient and can convert up to 95% of the fuel into heat.\u003c\/li\u003e\n\u003cli\u003eCost savings: Wood pellets are generally cheaper than oil or gas, so you can save money in the long term with our pellet boilers.\u003c\/li\u003e\n\u003cli\u003eConvenience: Pellet boilers operate automatically, and some models are fully automatic, requiring little intervention.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003ePellet boilers and environmentally friendly heating!\u003c\/h4\u003e\n\u003cp\u003eFrom the perspective of \"environmentally friendly heating,\" pellet heating and wood heating are still an excellent choice. When burned, wood releases as much carbon dioxide as it absorbs during growth. It is therefore considered a carbon-neutral fuel. Wood is a constantly renewable and therefore sustainable raw material. Our wood and pellet boilers were therefore designed in accordance with the applicable emission guidelines and meet the strict requirements of the applicable BImSchV.\u003c\/p\u003e\n\u003ch3\u003eDownload\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" title=\"Alpha II Datenblatt\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/ALPHA_II_Datenblatt.pdf?v=1729244053\" aria-label=\"Besuchen Sie eine Webseite über Alpha II Datenblatt\" target=\"_blank\"\u003eData sheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Defro","offers":[{"title":"12kW \/ Base","offer_id":49005340393820,"sku":"DAII12","price":10057.76,"currency_code":"EUR","in_stock":true},{"title":"12kW \/ Plus","offer_id":49005340426588,"sku":"DAII12P","price":10543.76,"currency_code":"EUR","in_stock":true},{"title":"17kW \/ Base","offer_id":49005340492124,"sku":"DAII17","price":10798.94,"currency_code":"EUR","in_stock":true},{"title":"17kW \/ Plus","offer_id":49005340524892,"sku":"DAII17P","price":11284.94,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/pelletkessel-defro-alfa-ii-12-17-kw-forderfahig-5867235.png?v=1770692732","url":"https:\/\/ee.gemashop.de\/en\/products\/alfa-ii-pelletikatel-tsentraalse-pelletipoletiga-12-17-kw-toetuskolblik","provider":"GEMA Shop","version":"1.0","type":"link"}
