    FAQs

    How do I re-pressurise a boiler?

    Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:

    • Switch off your boiler and let it cool completely

    • 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!

    What size boiler do I need?

    The size of boiler you need will depend on the size of your home, how many radiators and bathrooms you have and how many people live there. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you. Other boiler types such as system boilers or conventional boilers may be better suited to larger homes because they have bigger outputs.

    How long does a boiler last?

    If you get the right size boiler for your home and you get it serviced regularly, your boiler could last up to 15 years. It may even last longer than this, but you’ll find that your boiler begins to become less efficient as it gets older. Also, as technology improves, a boiler older than 15 years may not be the most efficient one on the market.

    how does a gas boiler work?

    A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

    Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

    ✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

    ✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

    ✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

    ✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer
