Glow-worm Boiler Calculator
Our latest boiler calculator has been designed to help you choose which boiler would be best suited for your home.
Simply enter your postcode into the interactive tool below to get started.
Details like your postcode help our machine to calculate intricate details such as the average sunshine hours, ambient temperature and ground temperature for your area. This gives us a better overview of the amount of energy you’re currently using, as well as how you can best reduce costs.
We’ll then ask you a few more simple questions about your property, such as its type and age, as well as the number of residents and bedrooms, in order to further refine our calculations.
Lastly, we’ll need to know what kind of heating system you currently use. If you’re unsure, you can always check your boiler’s literature or contact your current energy provider.
With the relevant data inputted, our calculator will get to work, crunching the numbers and finding the best Glow-worm boiler for your property.
