This obligation exists not only for your safety but also to guarantee energy efficiency and correct combustion. The exact rules depend on the region where you live.  <\/p>\n\n<p><strong>How often must a gas boiler be inspected?<\/strong><br\/>In Belgium, a mandatory inspection every two years applies to natural gas boilers in most cases. This applies in: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Flanders<\/li>\n\n\n\n<li>Brussels<\/li>\n\n\n\n<li>Wallonia<\/li>\n<\/ul>\n\n<p>Stricter deadlines apply to heating oil boilers, but biennial maintenance is the standard for natural gas boilers.<\/p>\n\n<p><strong>What does the inspection of a gas boiler involve?<\/strong><br\/>During the mandatory inspection, a certified technician performs, among other things:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Cleaning of the boiler<\/li>\n\n\n\n<li>Inspection of the burner<\/li>\n\n\n\n<li>Measurement of combustion values<\/li>\n\n\n\n<li>CO emission check<\/li>\n\n\n\n<li>Checking draft and ventilation<\/li>\n<\/ul>\n\n<p>Afterwards, you will receive an official maintenance certificate. You must be able to present this document during inspections or in the event of insurance claims. <\/p>\n\n<p><strong>Who is responsible for the inspection?<\/strong><br\/>Responsibility depends on your living situation.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>In a rental property, the tenant is usually responsible for the periodic maintenance of the gas boiler.<\/li>\n\n\n\n<li>In an owner-occupied house or apartment, the owner is responsible.<\/li>\n\n\n\n<li>For communal heating installations in an apartment building, the Owners Association (VME) is responsible. The Property Manager then handles the planning and follow-up of the maintenance. <\/li>\n<\/ul>\n\n<p><strong>What if you do not have the gas boiler inspected?<\/strong><br\/>Failure to comply with the maintenance obligation 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 case of damage<\/li>\n\n\n\n<li>Increased risk of CO poisoning<\/li>\n\n\n\n<li>Reduced energy efficiency<\/li>\n<\/ul>\n\n<p>A poorly maintained gas boiler can be dangerous and consume more energy.<\/p>\n\n<p><strong>Must a gas boiler be inspected upon sale?<\/strong><br\/>When selling a home, there is no separate \"sales inspection\" as there is for electricity. However, the installation must be compliant and correctly maintained. The maintenance certificate can play an important role in the sales file.  <\/p>\n\n<p><strong>What is the conclusion?<\/strong><br\/>In Belgium, a natural gas boiler must undergo a mandatory inspection and maintenance every two years by a certified technician. The tenant or owner is usually responsible, unless it concerns a communal installation. Regular maintenance is not only legally required but, above all, essential for safety and energy-efficient use. Whatever the cause, always take the problem seriously. If the malfunction persists, an inspection by a certified electrician is necessary. Electrical protection exists to prevent danger, not to be bypassed.     <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>An inspection takes an hour \u2014 peace of mind lasts two years.<\/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_2e9a52831859a8da73f5c583502f12ee\" 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, and the strength of a professional group.
