  • How do I prepare my home for a boiler installation?

    From finding the perfect boiler for your home, understanding the various types of boilers and preparing your home for an installer, there are a few important steps you need to take to ensure your home is ready for a new boiler installation.

  • How often do I need to service my boiler?

    The answer to this depends on how your boiler is used. It requires servicing annually, which for the vast majority of installations is fine.

    If you have a boiler installed or used for an unusual application, which means the boiler is operating more than expected, it may require servicing more frequently. However, for normal use, annual servicing is sufficient.

  • How do I register my boiler for warranty?

    There are a few different ways you can register your free boiler warranty, which needs to be done within 30 days of installation.

    • Installers can log in or sign up for a Connect loyalty account and earn points for every eligible product registered through your account - visit InstallerConnect.com to learn more.

    If this is not available, you can also determine the age of your boiler by calling our Customer Service team on +35319617700. From here, you can quote the boiler serial number, which can be found either underneath or on top of your boiler, depending on your specific appliance.

  • What is a condensing boiler?

    A condensing boiler is a high-efficiency boiler which runs at a lower temperature than older, traditional-style boilers. Condensing boilers are able to collect gas generated by burning fuels like gas and oil and use it to heat water entering the system, saving money and reducing carbon emissions in the process.
