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.
In the UK, more than 50 percent of the money paid for utility bills is aimed at heating and hot water costs as stated by the Energy Saving Trust. This also means that when you settle for an old or ageing boiler, you’ll have to unnecessarily incur high utility bill in order to heat your home and have hot water on demand. In this kind of situation, the most effective and practical solution is to fit a new gas boiler in your home. This will provide you several benefits such as improved efficiency and reliability as well as reduced operating costs.
However, the only drawback here is the fact that removing your old gas boiler and replacing it with a new gas boiler isn’t a 5 minute task. And as you would have expected, like many other home improvement project there’s always an element of disruption that you’ll have to put into consideration when fitting a new gas boiler system. Good news is, with a qualified and experienced heating companies, these disruptions can be kept at a minimum. So now let’s take a look at how long it’ll take to replace a gas boiler depending on the type.
✓ An existing combi boiler upgrade - Installation times may vary, but typically the removal of an existing combi boiler and installation of a new one will usually be completed in a day - about four to six hours.
✓ Converting a regular to a combi boiler - Due to the fact that these type of project is usually labour intensive, it’ll take longer to complete - about 2 days.
✓ First time installation of new boiler to a home. This will usually take about 3 or more days because new pipes and other tasks need to the installation will be carried out.
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.
Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:
• Switch off your boiler and let it cool completely
• Make sure both ends of your filling loop are attached
• Open both valves to allow cold water into the system – you’ll hear it start to move
• Look out for your pressure gauge to show 1.5 bar
• Close both valves
• Switch your boiler back on
• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!
