This hot water is then distributed throughout the home via a network of radiators or underfloor heating. It's one of the most economical and environmentally friendly alternatives to traditional fossil fuels. Unlike a traditional wood-burning stove, a boiler heats the entire house; a stove only heats the room where it's installed.<\/p><h2>Main types of wood boilers<\/h2><ul><li><strong>Traditional combustion boilers<\/strong>They operate by natural or forced draft. They have lower efficiency and require more frequent wood loading.<\/li><li><strong>Gasification boilers (Inverted flame)<\/strong>These are the most efficient. They burn the wood in an upper chamber and the resulting gases in a lower chamber. They achieve efficiencies exceeding 90%.<\/li><li><strong>Combination or multi-fuel boilers<\/strong>They allow you to alternate firewood with other fuels such as pellets, offering greater flexibility.<\/li><\/ul><h2>Advantages and Disadvantages<\/h2><p><!-- \/wp:paragraph --><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-5bd2d06 e-con e-atomic-element e-flexbox-base e-8ff559f\" data-id=\"5bd2d06\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"5bd2d06\">\n    <div class=\"elementor-element elementor-element-139a16c e-grid e-con-boxed e-con e-parent\" data-id=\"139a16c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<p class=\"e-097b32f-3b862fd e-paragraph-base\" data-interaction-id=\"097b32f\">Aspect<\/p>\n\t\t\t\t\t<p class=\"e-33b7f97-0ac1d32 e-paragraph-base\" data-interaction-id=\"33b7f97\">Advantages<\/p>\n\t\t\t\t\t<p class=\"e-cc34914-c238a2d e-paragraph-base\" data-interaction-id=\"cc34914\">Disadvantages<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-0644910 e-grid e-con-boxed e-con e-parent\" data-id=\"0644910\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<p class=\"e-e594ccc-eb1b67a e-paragraph-base\" data-interaction-id=\"e594ccc\">Economy<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"a3072b9\">Fuel is very cheap or free if you have direct access to wood.<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"7a05d67\">The initial investment for purchase and installation is high.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7c68912 e-grid e-con-boxed e-con e-parent\" data-id=\"7c68912\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<p class=\"e-ebb2fbb-8033536 e-paragraph-base\" data-interaction-id=\"ebb2fbb\">Sustainability<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"fab9e91\">Renewable energy with a neutral CO\u2082 emissions balance.<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"8a9e52f\">It requires a large, dry physical space to store firewood.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4a0be7b e-grid e-con-boxed e-con e-parent\" data-id=\"4a0be7b\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<p class=\"e-0d5e567-da029bc e-paragraph-base\" data-interaction-id=\"0d5e567\">Performance<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"dbeb301\">Advanced technology (gasification) that makes the most of every log.<\/p>\n\t\t\t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"4805310\">It requires constant manual maintenance (daily loading and ash cleaning).<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-101f88b e-con e-atomic-element e-flexbox-base e-a1494b5\" data-id=\"101f88b\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"101f88b\">\n    \t\t<div class=\"elementor-element elementor-element-63e250f elementor-widget elementor-widget-text-editor\" data-id=\"63e250f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Essential components in an installation<\/h2><ul><li><strong>Inertia reservoir<\/strong>This is a mandatory water tank for gasification boilers.
