    FAQs

    how long does it take to replace a gas boiler?

    In the UK, more than 50 percent of the money paid for utility bills is aimed at heating and hot water costs as stated by the Energy Saving Trust. This also means that when you settle for an old or ageing boiler, you’ll have to unnecessarily incur high utility bill in order to heat your home and have hot water on demand. In this kind of situation, the most effective and practical solution is to fit a new gas boiler in your home. This will provide you several benefits such as improved efficiency and reliability as well as reduced operating costs.

    However, the only drawback here is the fact that removing your old gas boiler and replacing it with a new gas boiler isn’t a 5 minute task. And as you would have expected, like many other home improvement project there’s always an element of disruption that you’ll have to put into consideration when fitting a new gas boiler system. Good news is, with a qualified and experienced heating companies, these disruptions can be kept at a minimum. So now let’s take a look at how long it’ll take to replace a gas boiler depending on the type.

    ✓ An existing combi boiler upgrade - Installation times may vary, but typically the removal of an existing combi boiler and installation of a new one will usually be completed in a day - about four to six hours.

    ✓ Converting a regular to a combi boiler - Due to the fact that these type of project is usually labour intensive, it’ll take longer to complete - about 2 days.

    ✓ First time installation of new boiler to a home. This will usually take about 3 or more days because new pipes and other tasks need to the installation will be carried out.

    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

    do i need a new boiler?

    Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

    ✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

    ✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

    ✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

    ✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

    How does the A-G gas boiler rating system work?

    The A-G scale refers to the energy efficiency of your boiler. G-rated boilers are the least efficient, and give you less heat and hot water for your money. Installing an A-rated boiler will reduce your energy bills and carbon emissions. Don't compromise on cheaper, lower rated boilers, you will save yourself more money longer term with an A-rated model.
