          What happens at a boiler service?

          During a boiler service, your engineer will carry out various checks and inspections, including but not limited to:

           
          •    Correct gas pressure and flow
          •    Flue and combustion
          •    Condition of electrical connections
          •    Fans and other key components 
          •    Seals are intact
          •    Electrodes are in a good condition
          •    Safety devices are checked
          •    Condensate trap and pipe is not blocked
          •    Water and gas pipework

          Can I run a bath and shower at the same time?

          If you have a cylinder installed, you should be able to run a bath and shower at the same time. If you have a combi boiler, you may notice a drop in performance as the boiler splits the hot water between the shower and the bath.

          What are the different types of boilers?

          The main types of boilers are: 

          • Combi
          • System
          • Heat only
          • Electric

          Learn about the pros and cons of each type here.

          Why is my boiler leaking?

          If you suspect your boiler is leaking, check for error codes on the appliance, any dampness or dripping, and your pressure level for indications. We also have a range of How-to Guides to help troubleshoot the problem.
