Three parts make up each metre: a fireclay flue liner, a rock wool insulation board around it, and an outer concrete block that carries the load. The insulation keeps the flue gas warm, which is what keeps the draught working and the condensate out of the masonry.\u003c\/p\u003e\u003cp\u003eIt takes any solid fuel — wood, coal, pellets, mixed-burner boilers, fireplaces and stoves, whether factory-built or built on site. Where the outer blocks include a ventilation duct, the combustion air can be drawn from outside the building instead of from the room, which matters in a well-sealed house.\u003c\/p\u003e\u003cp\u003eThe flue diameter is not a matter of preference. It follows from the boiler output, the fuel and the useful height of the chimney — Leier publishes a sizing diagram for exactly this. Too wide a flue cools the gas and kills the draught; too narrow a one chokes the appliance.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey benefits\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eInsulated: fireclay liner, rock wool board, load-bearing concrete outer block\u003c\/li\u003e\n  \u003cli\u003eSix diameters, from 140 to 300 mm\u003c\/li\u003e\n  \u003cli\u003eAny solid fuel — wood, coal, pellets, mixed burners, fireplaces, stoves\u003c\/li\u003e\n  \u003cli\u003eOuter blocks with a ventilation duct can supply combustion air from outside\u003c\/li\u003e\n  \u003cli\u003eResistant to high flue gas temperatures and to acid condensate\u003c\/li\u003e\n  \u003cli\u003eThree components per linear metre, dry and quick to build\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eProduct type: insulated ceramic chimney system\u003c\/li\u003e\n  \u003cli\u003eBrand: Leier\u003c\/li\u003e\n  \u003cli\u003eRange: LSK\u003c\/li\u003e\n  \u003cli\u003eFlue diameters: 140, 160, 180, 200, 250 and 300 mm\u003c\/li\u003e\n  \u003cli\u003eOuter dimensions: 35 x 35 cm (140 \/ 160), 40 x 40 cm (180 \/ 200), 48 x 48 cm (250), 57 x 57 cm (300)\u003c\/li\u003e\n  \u003cli\u003eWeight: 118–229 kg per linear metre, depending on diameter\u003c\/li\u003e\n  \u003cli\u003eConsumption: 3 pieces per linear metre of each component\u003c\/li\u003e\n  \u003cli\u003eUse: solid fuel boilers, stoves and fireplaces\u003c\/li\u003e\n  \u003cli\u003eSold by: linear metre\u003c\/li\u003e\n  \u003cli\u003eDelivery: made to order, subject to supplier stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eRecommendation\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSize the flue from Leier's sizing diagram, using the boiler output and the useful height of the chimney — the vertical distance from the appliance connection to the top. The diagram covers a single wood boiler on one flue; connecting two appliances to the same flue needs a separate calculation. Order the full height in one go, including the part above the roof, and add the terminal set. A chimney is not a place to economise: the cost difference between two diameters is small next to the cost of rebuilding one that does not draw.\u003c\/p\u003e","brand":"Leier","offers":[{"title":"140 mm","offer_id":57161659548026,"sku":"HGM-CS-LIR-LSK-14","price":0.0,"currency_code":"RON","in_stock":true},{"title":"160 mm","offer_id":57161659580794,"sku":"HGM-CS-LIR-LSK-16","price":0.0,"currency_code":"RON","in_stock":true},{"title":"180 mm","offer_id":57161659613562,"sku":"HGM-CS-LIR-LSK-18","price":0.0,"currency_code":"RON","in_stock":true},{"title":"200 mm","offer_id":57161659646330,"sku":"HGM-CS-LIR-LSK-20","price":0.0,"currency_code":"RON","in_stock":true},{"title":"250 mm","offer_id":57161659679098,"sku":"HGM-CS-LIR-LSK-25","price":0.0,"currency_code":"RON","in_stock":true},{"title":"300 mm","offer_id":57161659711866,"sku":"HGM-CS-LIR-LSK-30","price":0.0,"currency_code":"RON","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/5050\/8410\/files\/Cos-de-fum-Leier-LSK.webp?v=1786606573","url":"https:\/\/heligom.com\/en\/products\/leier-lsk-chimney-system","provider":"HELIGOM","version":"1.0","type":"link"}
