    FAQs

    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.

    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.

    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.

    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.
