Boiler flues are an essential boiler part, preventing potentially dangerous fumes from building up in your home. The boiler flue carries these gasses safely out of your house either via the roof or an external wall. Horizontal boiler flues exit straight out of the wall, typically the external wall behind the boiler, and are the most common type of flue in the UK. Ensure your home stays safe and, of course, warm—explore our range of horizontal boiler flues below and find the perfect flue for your home.
