Purchasing a new boiler can be a daunting process, particularly if you have never done it before. Here Sime’s John Moran explains the installation process and how to choose the right boiler for you and your home.

  1. Choosing your boiler

Deciding on a new boiler can be a difficult decision, but it’s an extremely important one. There are three different types to choose from: system, combi and conventional and the type you can have will depend on space, how much water you use and your gas connection. Boilers generally last for 12-15 years and can cost anything between £500 and £2,500 (not including installation) depending on the type and size you choose, so making sure that you select the best one for your home and lifestyle is essential.

When replacing an existing boiler, many homeowners choose to install the same type as they had before as this is the cheapest and easiest option, but it is not always the best. For example, a more energy efficient boiler can save you money in the long run, so the benefits can outweigh the initial expense and disruption. It is always worth considering your options.

  1. Choosing an installer

Selecting an installer to fit your boiler is another important decision. You want someone you can trust but also, most importantly, someone who is Gas Safe registered. You can find your nearest Gas Safe registered installer here.

Your installer will be able to advise you on the type of boiler they would recommend, as well as the size and where to install it. However, it’s important to remember that not all installers install all types of boilers and installers will usually have a preferred manufacturer.

  1. Preparing for your installation

The amount of preparation you do will minimise the disruption caused to you and your family/housemates on the day of the installation. Your installer will usually visit you before your appointment to update you on the process and ask you a few questions about your current boiler.

It’s important that you know what they will need access to before the installation begins. For example, if you water cylinder is in your loft, it’s important that this is easily accessible so your installer can complete the job. Also, as your installer will be in and out of your house during the day, moving furniture might also be a good idea – particularly if there is not a lot of space between the door and the boiler location. Clearing a space on your driveway or outside your house for the van is also something to think about.

  1. The installation process

Your installer will give you a date and time prior to your installation and the process itself will usually take no longer that a day to complete, however this depends on the type of installation and if the installer encounters any problems.

We would always recommend that you are at home while the installation is taking place to manage the process and to sort out any issues.

  1. Once your boiler is installed

Once your new boiler is connected and ready to use, you have 30 days to register your new boiler on the Gas Safe register and with your boiler manufacturer. Boiler warranties usually last between one and 10 years, so it’s important to check this with the manufacturer and download a user manual.  You can register your Sime boiler here.

It’s important to remember that your boiler should be serviced annually, so we would recommend making a note of the date of installation so you know when your service will be due.

Do I need a new boiler?

If your boiler is more than 12 years old or it is starting to show signs that it might need replacing, it is a good idea to contact your local gas engineer for advice. By putting the relevant preparations in place over the summer, you are reducing the risk of a breakdown over the winter months – the time you need it the most. Remember that the winter is also the busiest time for installers so it could take longer to get your problem fixed!
