Replacing your boiler

Looking to upgrade your boiler? At Glow-worm, we offer three different types of boilers to meet your heating and hot water demands. Our boilers are designed to maximise home efficiency via the highest quality, reliability, and performance for any living requirements.

All our boilers have an ErP of 'A', making them highly efficient which can help to save you money on your energy bills.

When choosing a new boiler, there are a few requirements we recommend you consider:

  • Do you want a like-for-like replacement?
  • Consider hot water output.
  • See if you have enough space.
  • Make sure it aligns with your budget.

Our boiler-range is designed so that there is a system that meets the heating demands of your home regardless of size. If you need help choosing your new Glow-worm boiler read our 'What boiler do I need for my home' or contact your local Club Energy installer, who can advise you on the right boiler for your home.

Combination boilers

Combi boilers are a convenient all-in-one solution for smaller households with low hot water demands (such as one shower or bath), that would benefit from hot water almost instantly and a perfectly heated home.


System boilers

These boilers are fitted with a cylinder to provide steady hot water and a comfortable home temperature. These boilers are perfect if you have a high water demand from multiple sources at once.


Regular (open vent) boilers

Offering heating comfort and hot water for larger households with multiple bathrooms and high hot water demand.


The benefits of replacing your boiler

Glow-worm boilers are designed to be reliable and come with a minimum guarantee of 5 years. However there is the option to extend up to 10 years.*

Your boiler guarantee covers any repairs or system-related defects. You can register your boiler online on myGLOWWORM Web or ask your Club Energy Installer to do it on your behalf.

*Please note: Our extended guarantees are available when installed and registered by a Glow-worm Club Energy installer.

If you want to get the most out of your boiler, you can upgrade your system by adding a smart heating control or thermostat, so you really take charge of your homes heating.

We recommend pairing your Glow-worm boiler with one of our Glow-worm smart controls, as it allows you to control your home through your smart home via an internet connection. The controls let you tailor your heating and hot water to improve your home's energy efficiency.
