    FAQs

    how much is a new gas boiler?

    If you’re thinking about getting a new gas boiler for your home or property, then you might also be wondering how much it’ll cost you so you can set a budget and start planning. As simple as this question sounds, it’s actually very tricky to provide a simple and short answer as the costs of installing a new gas boiler alone varies greatly based on the parts needed, the amount of work required, your location, their availability as well as the company you hire for the project.

    When it comes to purchasing a new gas boiler the price you’re expected to pay also depends on multiple influencing factors such as the type, brand as well as your most preferred gas boiler model. However, one thing you should have in mind is the fact that your gas boiler is right at the heart of your home or property and can be a complicated piece of machinery. As a result, you wouldn’t expect gas boilers to come cheap. Generally, it’s going to cost within the range of £500 to about £2,500 to get a new gas boiler. Therefore, it’s always advisable to obtain all necessary details and facts before you decide to purchase a replacement gas boiler.

    This price range may seem too high as it’s usually a turn off for most homeowners. However, it’s worth noting that gas boiler replacement costs and gas boiler installation costs are, more often than not, compensated by the saving you’ll make off your utility bills - all thanks to the new and more energy efficient boiler you just installed in your home. And even more importantly, when it has been estimated that roughly half of the amount spent on energy on an annual basis depends on your boiler.

    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.

    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!

    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.
