Boiler size calculator
Which Glow-worm boiler is right for your home?
We know that trying to find the right boiler for your property is a difficult thing to do, so we have designed this boiler size calculator to help you find the boiler best suited for your home. Once you have submitted a few details about your property and the amount of occupants currently living there, our calculator will give you a suggested heating appliance for your home. If you are happy with the suggestion that has been given to you, feel free to get in touch with a local installer through our Find an Installer tool to enquire about it!
