    FAQs

    how long does a gas boiler last?

    When it comes to gas boilers, this is one of the most frequent questions that always pops up and for a good reason. When you invest a considerable amount of money to acquire and install a gas boiler in your home or property, it’s only reasonable not only to expect the boiler to warm up your home efficiently, but also to do so for a long period of time. If you’ve just bought or about to get a new gas boiler, it’s likely you won’t have to worry about getting a replacement for a lengthy period of time. Several gas boilers will last for anywhere between 10 to 15 years on the average. However in the event whereby you have an existing one that’s fast approaching the end of it’s useful life, then you should know the time go get a new gas boiler is just around the corner, and the earlier you make the purchase, the better (to avoid any surprise breakdowns that’ll leave your home super uncomfortable).

    Just like any other home appliance, it’s a fact that an older gas boiler ( especially those that have been installed over a decade ago) are significantly less efficient that the new modern ones. When the older versions were manufactured is a completely different time to now as both technology and climate concerns are wide apart. So when your existing boiler is approaching the end of it’s useful life, it’ll be wise to start saving up to cover the cost of getting a new one. However, if it’s only about 5 years ago your boiler was installed, it’s highly likely to still be very efficient.

    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.

    what is a condensing boiler?

    Condensing boilers are the in-thing when it comes to modern heating systems in UK homes and across the globe for a good reason. This is primarily due to the fact that condensing boilers happens to be highly efficient as it enables the fuel you’re burning to heat up your home go a lot further. Having a new high efficiency condensing boiler rather than an old G-rated non condensing boiler will not only enhance your heating controls, but also save you a lot of money annually. In this article, we’re going to take you through the basics of a condensing boiler. Let’s take a closer look!

    If you’re interested in getting a greener and more efficient boiler, you simply can’t afford to look beyond a high efficiency condensing boiler. This is purely due to the fact that these condensing boilers happens to make a better use of the heat they’re able to produce from burning fuels like oil or gas ( in other words, they require less heat from the burner, which makes them a lot more efficient).

    So how does a condensing boiler work? Unlike a non-condensing heat-nly boiler, some heat will be wasted in form of hot gases which are released from the flue. Meanwhile a condensing boiler captures some of the heat from these gases and puts them to use for heating up water that’s coming back from your central heating system. As a result, it requires just a minimal heat from the burner which make the boiler more efficient.

    You should take note that all new modern boilers are condensing boilers. Therefore if you’re planning to replace an old boiler with a new one, you’ll definitely be buying a new condensing boiler and benefit from all the efficiency and savings that comes with it.

    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
