The heating system is amongst the most significant areas of your home. Your central heating boiler provides you with heat and hot water all year round and the chances are you take little notice of it. Why would you if it's rolling out heat through the year without having a problem?
But wait, how expensive are your energy costs? Do you know replacing your central heating boiler can save you over £300 a year on bills due to the enhanced performance? If your boiler is in excess of 10-years old, then the likelihood is there's a large saving to make.
Nonetheless, investing in a brand new central heating boiler isn't the most affordable of home improvements. It's not the priciest either, and you could be looking at in between £1,500 and £2,000 for a very efficient combi boiler.
To help overcome this initial price you might consider central heating boiler finance. With finance you'll pay a monthly fee for however long you want to cover the cost of the boiler. This can be as little as 12 months and certainly helps people who can't afford the full one-off payment.
If your central heating boiler stops working all of a sudden also, you may want to take into consideration boiler finance without the funds quickly accessible in the bank. Boiler finance is ideal and although there is a small interest rate, it's a handy option.
The average cost of replacing your gas boiler is £2,500. Costs differ based on the type and brand of boiler you choose as well as the provider you decide to go with. For example, a small local business may be able to offer a better price than a large national tradesman as they will have fewer overheads. Itâs best to get a range of quotes from different boiler engineers so you can compare prices, reviews and references before going ahead.

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.
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.
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!
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.
