    FAQs

    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

    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 much is a new combi boiler?

    If you’re thinking about getting a new combi boiler, you may be wondering just how much it’s going to cost so as to start making preparations as soon as possible. However, providing a precise cost for the acquisition and installation of a new combi boiler is simply impossible as combi boiler prices vary greatly in price - usually ranging between £1500 to about £3500 based on the brand of the combi boiler, the insurance or warranty, installation, your location as well as the size and power of the appliance. Due to the fact that combi boilers are compact units which doesn’t need a hot water cylinder or a cold water tank to produce heating and hot water for homes, it’s a very popular type of boiler that’s frequently used especially in the UK.

    Combi boilers are also widely known to be the most energy efficient type of boiler because they are able to provide an instant supply of hot water anytime you turn on a tap. Combi boilers particularly perfect for flats and houses where space is limited as they have the ability to deliver instant heating and hot water without requiring any extra parts or components.

    In the event whereby you’re about to choose a combi boiler for your home or property, it’s always advisable to compare models as well as prices from only the most reliable and sought after brands across the globe. Depending on the manufacturer, the overall quality of the boilers as well as their prices can differ. However, regardless of your budget, you’ll discover there are a plethora of combi boilers available in the market that’ll also suit your taste.

    what is a combi boiler?

    A combination boiler, also referred to as a “combi boiler, delivers both domestic hot water and space heating in a single package so as to save space, and in a lot of cases, money. These great features makes the appliance a very popular choice in UK homes and in fact, it represents more than 50 percent of all new boilers fitted in the UK on a yearly basis.

    Most modern and high efficiency combi boilers are usually stainless steel condensing boilers which normally features an in-built secondary heat exchanger to deliver domestic hot water to a home or property. What’s more? When it comes to the heating season or the cold months, the combi boiler will operated as required to heat a structure and offer hot water for showers, sinks as well as other hot water appliances around the house. 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. As a result, in during the hot summer when space heating is not required, you’ll only have to pay to heat up the hot water that you really need and not an entire tank.

    Combi boilers also have the following benefits:

    ✓ Lower costs. Due to the combined nature of the boiler and the lack of tank in the roof space, the installation time and costs are at a minimum.

    ✓ Saves space in your home as it effectively combines a central heating boiler with a water heater into one unit.
