    • Make sure both ends of your filling loop are attached

    • Open both valves to allow cold water into the system – you’ll hear it start to move

    • Look out for your pressure gauge to show 1.5 bar

    • Close both valves

    • Switch your boiler back on

    • Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

And when it gets to the warm season or summer months, the combi boiler will only work when there’s a need for domestic hot water which also helps you save more money.

    Combi boilers are able to provide domestic hot water in such a way that’s energy efficient due to two primary reasons - the combi units possess a very high operating efficiency and also have a low internal water volume.
