Which boiler works best for you?

Are you looking to upgrade your boiler? Here at Glow-worm, we offer three different types of boilers to meet your heating and hot water demands. Our products offer the highest quality, reliability and performance and suit a wide range of living spaces.

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 your new boiler, there are a few things you need to consider. Depending on your requirements, we recommend doing a like-for-like replacement. However, if you are fully upgrading your heating system, you will need to consider your hot water output, if you have enough space and your budget.

If you need help with choosing your new Glow-worm boiler, contact your local Club Energy installer who will be able to 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.


Benefits of replacing your boiler

Extended guarantee available

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

Your boiler guarantee covers any repairs and defects related to the manufacture. You can register your boiler online or you can 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.

Boiler Plus

Boiler Plus is government legislation which ensures that homes in the UK have efficient heating systems. Since 2018, all new boiler installations require a minimum ErP efficiency of 92% and have time and temperature controls fitted.

If you’re having a new combi boiler installed, they now require one of four additional criteria to comply with Boiler Plus. Choosing the best option that works for each home is important as different homes have unique requirements.

Any new boiler installations after April 2018 must be compliant with Boiler Plus.
