This type of system is increasingly being used in modern homes where there is no existing <a class=\"wpil_keyword_link\" href=\"https:\/\/pelletkachelvoordeel.be\/en\/pelletkachels-2\/installation-and-placement\/is-a-chimney-required-for-a-pellet-stove\/\" title=\"Do you need a chimney for a pellet stove?\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"51904\">chimney<\/a> is present or when a more efficient flue gas discharge system is chosen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"hoe-werkt-het-UMJNPOGoyE\">How does it work?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The smoke produced by burning wood is released via a <strong>double-walled flue<\/strong> led outside. This duct usually runs through the fa\u00e7ade or through the roof to the outside. Thanks to the double wall, the outside of the duct remains relatively cool, which increases safety and prevents condensation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"voordelen-van-een-houtkachel-met-externe-afvoer-UMJNPOGoyE\">Advantages of a wood stove with external exhaust<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Flexible placement:<\/strong> You are not tied to the location of an existing chimney.<\/li>\n\n\n\n<li><strong>Higher security:<\/strong> Using insulated flue pipes minimises fire risk.<\/li>\n\n\n\n<li><strong>Better returns:<\/strong> A well-designed exhaust system improves draught and therefore combustion.<\/li>\n\n\n\n<li><strong>Reduced odour and smoke pollution:<\/strong> Smoke is discharged higher, limiting nuisance to neighbours.<\/li>\n\n\n\n<li><strong>Sustainable alternative:<\/strong> When used correctly, wood is a renewable energy source.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"installatie-van-een-houtkachel-met-buitenafvoer-UMJNPOGoyE\">Installation of a wood-burning stove with external flue<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The installation of a wood-burning stove with external flue requires skill. It is important to comply with applicable building regulations and safety standards. Below are the main steps:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-keuze-van-de-juiste-kachel-UMJNPOGoyE\">1. Choosing the right stove<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Choose a stove that suits the size of your room and your heating needs. Pay attention to the <a href=\"\/en\/houtkachel-rendement\/\">wood stove efficiency<\/a>, which is ideally above the 75%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-bepalen-van-het-rookkanaaltraject-UMJNPOGoyE\">2. Determining the flue route<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The flue should rise as straight as possible to ensure optimum draught. Bends reduce efficiency and increase the risk of creosote formation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"3-gebruik-van-dubbelwandige-rookkanalen-UMJNPOGoyE\">3. Use of double-walled flue pipes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Double-walled stainless steel channels<\/strong>, also called insulated flue pipes, are mandatory when passing through walls or roofs. They ensure fire safety and reduce heat loss.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"4-dakdoorvoer-of-geveldoorvoer-UMJNPOGoyE\">4. Roof penetration or gable penetration?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Roof penetration:<\/strong> The most efficient option; provides natural draft.<\/li>\n\n\n\n<li><strong>Fa\u00e7ade penetration:<\/strong> Possible in low-rise buildings, but often requires additional ventilation facilities.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"5-professionele-installatie-UMJNPOGoyE\">5. Professional installation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Make sure you work with a recognised installer who is experienced in flue systems. Incorrect installation can lead to carbon monoxide poisoning or fire risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wettelijke-eisen-en-regelgeving-in-nederland-UMJNPOGoyE\">Legal and regulatory requirements in the Netherlands<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Installing a wood-burning stove falls under the Building Code. This means you have to comply with various requirements on fire safety, ventilation and emissions.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NEN standards:<\/strong> Installations must comply with NEN-EN 15287-1 (flue gas extraction systems).<\/li>\n\n\n\n<li><strong>Notification requirement:<\/strong> In some municipalities, you have to report when installing a new stove or duct.<\/li>\n\n\n\n<li>Central government on wood smoke nuisance<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"duurzaamheid-en-milieueffecten-UMJNPOGoyE\">Sustainability and environmental impact<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Sustainable heating<\/em> starts with well-dried wood (maximum 20% moisture content) and efficient combustion technology. Modern wood-burning stoves produce significantly less particulate matter than older models.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"duurzame-tips-voor-verantwoord-stoken-UMJNPOGoyE\">Sustainable tips for responsible heating:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Choose certified firewood:<\/strong> For example, FSC- or PEFC-certified wood.<\/li>\n\n\n\n<li><strong>Fit a particulate filter:<\/strong> Some models are equipped with catalytic converters or filters that reduce emissions.<\/li>\n\n\n\n<li><a href=\"\/en\/milieuvriendelijk-stoken\/\">Read more about environmentally friendly heating<\/a><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"kostenoverzicht-wat-kost-een-houtkachel-met-buitenafvoer-UMJNPOGoyE\">Cost overview: What does a wood stove with external flue cost?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Several factors influence the total cost:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Purchase stove:<\/strong> \u20ac800 - \u20ac3000 depending on brand and power.<\/li>\n\n\n\n<li><strong>External drain:<\/strong> \u20ac500 - \u20ac1500 depending on length, bends and choice of material.<\/li>\n\n\n\n<li><strong>Installation by installer:<\/strong> \u20ac500 - \u20ac1000 on average.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Total price is on average between \u20ac2000 - \u20ac5000 including VAT and installation costs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"onderhoud-en-veiligheidstips-UMJNPOGoyE\">Maintenance and safety tips<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Regular maintenance<\/em> is essential for optimal operation and safety.
