The home heating system is amongst the most crucial parts of the house. Your boiler will provide you with heat and hot water all through the year and the chances are you take little notice of it. Why would you if it's churning out warmth through the year with no problem?
But exactly how pricey are your energy bills? Are you aware that changing your boiler will save you more than £300 annually on bills due to the enhanced performance? If your central heating boiler is over 10-years old, then the chances are there's a huge saving to be made.
Nonetheless, paying for a brand new boiler isn't the most affordable of home improvements. It's not the priciest either, and you can be looking at between £1,500 and £2,000 for a very efficient combi central heating boiler.
To help overcome this initial cost you can think about central heating boiler finance. With finance you'll pay back a regular monthly fee for however long you choose to cover the cost of the boiler. This may be as few as 12 months and certainly helps those who can't afford the total one-off payment.
If your boiler breaks down abruptly too, you might like to think of boiler finance with no funds quickly accessible in the bank. Boiler finance is perfect and even though there's a small interest rate, it's a practical alternative.
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.

Condensing boilers are the in-thing when it comes to modern heating systems in UK homes and across the globe for a good reason. This is primarily due to the fact that condensing boilers happens to be highly efficient as it enables the fuel you’re burning to heat up your home go a lot further. Having a new high efficiency condensing boiler rather than an old G-rated non condensing boiler will not only enhance your heating controls, but also save you a lot of money annually. In this article, we’re going to take you through the basics of a condensing boiler. Let’s take a closer look!
If you’re interested in getting a greener and more efficient boiler, you simply can’t afford to look beyond a high efficiency condensing boiler. This is purely due to the fact that these condensing boilers happens to make a better use of the heat they’re able to produce from burning fuels like oil or gas ( in other words, they require less heat from the burner, which makes them a lot more efficient).
So how does a condensing boiler work? Unlike a non-condensing heat-nly boiler, some heat will be wasted in form of hot gases which are released from the flue. Meanwhile a condensing boiler captures some of the heat from these gases and puts them to use for heating up water that’s coming back from your central heating system. As a result, it requires just a minimal heat from the burner which make the boiler more efficient.
You should take note that all new modern boilers are condensing boilers. Therefore if you’re planning to replace an old boiler with a new one, you’ll definitely be buying a new condensing boiler and benefit from all the efficiency and savings that comes with it.
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.
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!
If you’re thinking about getting a new combi boiler, you may be wondering just how much it’s going to cost so as to start making preparations as soon as possible. However, providing a precise cost for the acquisition and installation of a new combi boiler is simply impossible as combi boiler prices vary greatly in price - usually ranging between £1500 to about £3500 based on the brand of the combi boiler, the insurance or warranty, installation, your location as well as the size and power of the appliance. Due to the fact that combi boilers are compact units which doesn’t need a hot water cylinder or a cold water tank to produce heating and hot water for homes, it’s a very popular type of boiler that’s frequently used especially in the UK.
Combi boilers are also widely known to be the most energy efficient type of boiler because they are able to provide an instant supply of hot water anytime you turn on a tap. Combi boilers particularly perfect for flats and houses where space is limited as they have the ability to deliver instant heating and hot water without requiring any extra parts or components.
In the event whereby you’re about to choose a combi boiler for your home or property, it’s always advisable to compare models as well as prices from only the most reliable and sought after brands across the globe. Depending on the manufacturer, the overall quality of the boilers as well as their prices can differ. However, regardless of your budget, you’ll discover there are a plethora of combi boilers available in the market that’ll also suit your taste.
