If you&#8217;re having trouble finding the age of your boiler, or any other queries that we could help you with, <a href=\"https:\/\/www.plusheat.co.uk\/contact\/\" target=\"_blank\" rel=\"noopener\">give us a call at 0808 164 2892 <\/a><\/div>\n<h2>Find out your boiler&#8217;s serial number<\/h2>\n<p>The easiest way to find out the age of your boiler is to look for its serial number. A serial number is a long sequence of numbers &amp; letters that are unique to that boiler.<\/p>\n<p>The number can be found in a few different places, such as a drop-down front panel, the side, or underneath the boiler. If you have the installation manual, then it will likely be in there.<\/p>\n<p><strong>If these tips don\u2019t help, here are a few more pointers to help you locate your boiler\u2019s serial number:<\/strong><\/p>\n<ul>\n<li><strong> Inside the Boiler Cabinet:<\/strong> In some cases, the serial number can be found inside the boiler cabinet, usually on a sticker or a metal plate. You may need to remove the boiler cover to access it, so be sure to follow safety guidelines and turn off the power to the boiler before doing so.<\/li>\n<li><strong> Owner&#8217;s Manual:<\/strong> If you have the owner&#8217;s manual that came with your boiler, the serial number is often documented there. Manuals can be a valuable resource for boiler information and maintenance instructions.<\/li>\n<li><strong> Online Resources:<\/strong> In this digital age, some manufacturers may provide online tools or databases where you can input your boiler&#8217;s model and serial number to retrieve specific information about your unit. This can be a convenient way to access important data.<\/li>\n<li><strong> Contact the Manufacturer<\/strong>: If you&#8217;re unable to find the serial number or need additional information about your boiler, don&#8217;t hesitate to reach out to the boiler manufacturer&#8217;s customer support. They can guide you through the process of locating the serial number and assist in identifying your boiler&#8217;s age and specifications.<\/li>\n<\/ul>\n<h2><strong>How old is my Worcester Boiler?<\/strong><\/h2>\n<p>Unfortunately, Worcester Boiler&#8217;s serial numbers were designed for internal use only.<\/p>\n<p>You&#8217;ll need to contact their <strong>support team on 0330 123 3366<\/strong>.<\/p>\n<p>Alternatively, if you know the fuel type, boiler type, and model name, you can use the <a href=\"https:\/\/www.ncm-pcdb.org.uk\/sap\/pcdbsearch.jsp?pid=26\" target=\"_blank\" rel=\"noopener\"><strong>official industry database<\/strong><\/a>.

Sometimes, these documents may contain information about the date of installation or service, which can help estimate the boiler&#8217;s age.<\/li>\n<\/ul>\n<h3>Do you have a Baxi, Vaillant, Vokera, or Ideal boiler?<\/h3>\n<p>We can assist you straight away and provide you with the age of your boiler in an instant.<\/p>\n<h2>How old is my Baxi boiler?<\/h2>\n<p>If your boiler was manufactured after 2003, the 4th and 5th digits in the serial number represent the year, and the 6th and 7th digits represent the week number within that year.<\/p>\n<p>E.g., if the 4th, 5th, 6th, and 7th digits read: 0610, the manufacture date is the 10th week in 2006.<\/p>\n<p>If your boiler is older than 2003, you can contact Baxi with your serial number at 0330 678 0917.<\/p>\n<h3><strong>Here&#8217;s some more information for Baxi boiler owners:<\/strong><\/h3>\n<ul>\n<li><strong> Interpreting the Serial Number<\/strong>: If you&#8217;re unsure how to interpret the serial number, here&#8217;s a breakdown. Let&#8217;s say the 4th, 5th, 6th, and 7th digits of your Baxi boiler&#8217;s serial number are 0610. This indicates that the boiler was manufactured in the 10th week of 2006.<\/li>\n<li><strong> Contact Baxi<\/strong>: If your Baxi boiler predates 2003 or you have trouble deciphering the serial number, you can contact Baxi directly at 0330 678 0917. They will be able to assist you in determining your boiler&#8217;s age.<\/li>\n<li><strong> Keep Records<\/strong>: It&#8217;s a good practice to keep records of your boiler&#8217;s serial number and other important information in a safe place. This makes it easier to access details when needed, especially if you require service or maintenance.<\/li>\n<\/ul>\n<h2><strong>How old is my Vaillant Boiler?<\/strong><\/h2>\n<p>A sticker is usually found either on the boiler itself or inside the front panel.<\/p>\n<p>When you find the serial number, go to the 3rd and 4th numbers of the serial code, and this will be the year the boiler was manufactured.<\/p>\n<p>For if the 3rd digit is 0 and the 4th digit is 1, this means this boiler was manufactured in 2001.<\/p>\n<p>Here are some extra tips to locate Vaillant Boiler&#8217;s serial number if the above-given method doesn&#8217;t work<\/p>\n<h3><strong> Locating the Serial Number:<\/strong><\/h3>\n<p>The first step is to locate the serial number of your Vaillant boiler. Typically, you&#8217;ll find a sticker either on the boiler itself or inside the front panel.<\/p>\n<p>The sticker contains important information about your boiler, including the serial number.<\/p>\n<h3><strong> Deciphering the Serial Number:<\/strong><\/h3>\n<p>Once you&#8217;ve found the serial number, you can use it to determine the year of manufacture. The relevant information is usually found in the 3rd and 4th digits of the serial code.<\/p>\n<p>These digits represent the year the boiler was manufactured.<\/p>\n<p><strong> Example<\/strong>: For instance, if the 3rd digit in your Vaillant boiler&#8217;s serial number is 0, and the 4th digit is 1, this means that the boiler was manufactured in the year 2001.<\/p>\n<h3><strong> Contacting Vaillant:<\/strong><\/h3>\n<p>If you encounter any difficulties locating the serial number or need further assistance, don&#8217;t hesitate to contact <a href=\"https:\/\/www.vaillant.co.uk\/contact\/contact\/\" target=\"_blank\" rel=\"noopener\">Vaillant customer support<\/a>.<\/p>\n<p>They can provide guidance on how to find the serial number and help you determine the age of your boiler.<\/p>\n<h3><strong> Keep Records:<\/strong><\/h3>\n<p>It&#8217;s always a good practice to keep a record of your boiler&#8217;s serial number and the date of manufacture for future reference.<\/p>\n<p>This information can be helpful when scheduling maintenance or when selling your property.<\/p>\n<p><span style=\"text-decoration: underline;\">By following these steps, you can easily determine the age of your Vaillant boiler and gain a better understanding of its history.<\/span><\/p>\n<p>Knowing the age of your boiler is essential for maintenance and ensuring it continues to operate efficiently.<\/p>\n<h2><strong>How old is my Ideal boiler?<\/strong><\/h2>\n<p>Refer to the Benchmark Certificate that can be found within the installation manual.<\/p>\n<p>If this isn&#8217;t available, the boiler age can be determined by the serial number, which can be found underneath or on top of the boiler.<\/p>\n<p>There are 3 different types of serial codes:<\/p>\n<ul>\n<li><strong>Ideal Logic\/Ideal M Series boilers:<\/strong> The very end code will be the manufacture date. Pre-2015 boilers are dated in the following format: YY\/MM\/DD; post-2015 boilers are dated following the normal UK format: DD\/MM\/YY<\/li>\n<li><strong>Ideal Classic:<\/strong> The 3rd cluster of numbers represents the year and week of the boiler being manufactured. E.g., if the 3rd cluster of numbers was 0612, the manufacture date was in the 12th week of 2016.<\/li>\n<li><strong>Ideal Mini:<\/strong> Go to the last 4 digits, which represent the month and year the boiler was manufactured. E.g., if the last 4 digits are 0308, the boiler was manufactured in March 2008.<\/li>\n<\/ul>\n<h2>How old is my Vokera boiler by serial number?<\/h2>\n<p>Find your serial number on a silver data plate on the underside of the boiler. The serial number will contain sixteen digits and one letter.<\/p>\n<p>The first eight digits refer to the boiler model, whilst the letter and the subsequent numbers refer to the year, month, and day the boiler was manufactured.<\/p>\n<p>Note that the serial number will never start with the number sequence 235.<\/p>\n<p>This number is the <strong>boiler&#8217;s bar code<\/strong>, not the serial number.<\/p>\n<h2>How old is my glow worm boiler?<\/h2>\n<p>If you own a Glow-worm boiler and want to know how old it is, the quickest way is by checking its serial number.
