The rules are stricter than for <a href=\"https:\/\/parte.be\/en\/blog\/technical\/when-must-a-gas-boiler-be-inspected-in-belgium\/\" type=\"post\" id=\"3005\">natural gas boilers<\/a>, as heating oil can cause more pollution and poses a higher risk in the event of poor combustion. <\/p>\n\n<p><strong>How often must a heating oil boiler be inspected?<\/strong><br\/>An annual maintenance obligation applies to heating oil boilers throughout Belgium.<\/p>\n\n<p>This means that your boiler:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Must be cleaned every year<\/li>\n\n\n\n<li>Must be checked every year<\/li>\n\n\n\n<li>Must undergo a combustion check every year<\/li>\n<\/ul>\n\n<p><strong>This applies in Flanders, Brussels, and Wallonia.<\/strong><br\/>What happens during the inspection of a heating oil boiler?<\/p>\n\n<p>A certified technician performs tasks including:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Cleaning of the burner and heat exchanger<\/li>\n\n\n\n<li>Inspection of the chimney and flue gas discharge<\/li>\n\n\n\n<li>Measurement of the soot number<\/li>\n\n\n\n<li>Checking CO and flue gas values<\/li>\n\n\n\n<li>Adjustment of the burner<\/li>\n<\/ul>\n\n<p>Afterwards, you will receive an official cleaning and combustion certificate. You must retain this document. <\/p>\n\n<p><strong>Who is responsible for the maintenance?<\/strong><br\/>Responsibility depends on the situation:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>In a rental property, the tenant is usually responsible for the annual maintenance.<\/li>\n\n\n\n<li>In an owner-occupied house or apartment, the owner is responsible.<\/li>\n\n\n\n<li>In the case of a communal heating installation in an apartment building, the Owners Association is responsible, via the Property Manager.<\/li>\n<\/ul>\n\n<p><strong>What if you do not have your heating oil boiler inspected?<\/strong><br\/>Failure to carry out the mandatory maintenance can have consequences:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Fines during inspections<\/li>\n\n\n\n<li>Insurance issues in the event of fire or a CO incident<\/li>\n\n\n\n<li>Higher fuel consumption<\/li>\n\n\n\n<li>Increased risk of soot formation or chimney fire<\/li>\n\n\n\n<li>Danger of carbon monoxide<\/li>\n<\/ul>\n\n<p>Furthermore, a poorly maintained heating oil boiler may break down more quickly.<\/p>\n\n<p><strong>What is the conclusion?<\/strong><br\/>In Belgium, a heating oil boiler must undergo a mandatory annual inspection and maintenance by a certified technician. This is stricter than for natural gas, where a biennial obligation usually applies. Annual maintenance is essential for safety, efficiency, and legal compliance.  <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>One maintenance service per year keeps you worry-free and warm through the winter.<\/p>\n<\/blockquote>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dashed\"\/>\n<div id=\"block-simple-banner-block_bbec2b7407f9dcc8001dcdbe7201f8e3\" class=\"block-simple-banner\">\n    <div class=\"bg-bg-inverse-base rounded-tl-[32px] rounded-br-[32px] rounded-bl-[164px] rounded-tr-[164px] overflow-hidden flex flex-wrap md:flex-row items-stretch\">\n        \n        <div class=\"w-full md:w-1\/2 flex flex-col justify-center p-8 md:p-12 md:pb-20 bg-bg-inverse-base inverse\">\n            \n\n<p class=\"has-text-align-left block-cta\">Work with Parte<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Will you also choose Parte<\/h2>\n\n\n\n<p class=\"p-subtitle subtitle-light\">At Parte, you get the best of both worlds: the personal approach of a local team that knows your building, combined with the strength of a professional group.
