    FAQs

    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.

    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.

    Can I stay at home while my gas boiler is being replaced?

    When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!

    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.
