    FAQs

    How do I know if my gas boiler needs replacing?

    If your boiler is making strange noises or smells, or doesn’t seem to be working properly, it may need replacing. Boilers usually last about 10-15 years. Even if your boiler is working normally, it’s worth replacing when it gets this old. An annual check will establish if there are terminal problems with a boiler that cannot be fixed.

    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 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 much is a british gas boiler?

    If you’re looking for a reliable or reputable source for your new gas boiler, you definitely won’t find much better than British Gas. Using a big firm like British Gas comes with a plethora of benefits , but of course there are also some drawbacks, with the boiler prices being the main one and biggest turn off for most homeowners. However, just before we delve straight in to the price, let’s look at a thing or two about the big company.

    The company, “British Gas are not a boiler manufacturer as you probably would have first imagined. They’re actually a company that specializes in the installation of boilers. As a result, they’re able to install just about any type of boiler you can imagine from any manufacturer. Be it a Worcester Bosch Greenstar 8000 Style or a Baxi 600, they’re able to provide you with the cost of having these boilers installed in your home or property.

    Combi boilers are perfect boilers for space-saving and this makes them very popular on the market. They’re also very efficient when it comes to heating water instantly and warm your in few minutes. The price of a new British Gas combi boiler varies on a number of factors. Generally, the installation prices of combi boilers start from £1,800. Therefore, if British Gas are to be competitive with their pricing it should also be around this price.

    However, if you have a large house with several rooms with a higher demand for hot water, British Gas will most likely recommend boilers such as Worcester Bosch 440CDi and the likes. Judging from other firms in the market, the price to have these types installed should be in excess of £3,000.
