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.

The London Borough of Haringey is a London borough in North London, classified by some definitions as a part of Inner London, and by others as part of Outer London. It was established in 1965 by the amalgamation of 3 former boroughs. It shares borders with six other London boroughs. Clockwise from the north, they are: Enfield, Waltham Forest, Hackney, Islington, Camden, and Barnet. Haringey covers an area of more than 11 square miles (28.5 km2). The local authority is Haringey London Borough Council.
In line with population estimates from the middle of 2014, Haringey features a permanent population of around 267541 inhabitants. There are about 97101 homes in Haringey. Of these, 46 per cent are owner occupied. The borough is characterised by some extreme contrasts. Areas within the west, such as Highgate, Muswell Hill and Crouch End are among the most prosperous in the country. Within the east of the borough, however, some wards are classified as being amongst the most deprived 10 per cent inside the country.
Haringey is also a borough of contrasts geographically. The borough contains large areas of green space, which make up more than 25 per cent of its total area. A few of the more familiar local landmarks consist of Alexandra Palace, Bruce Castle, Jacksons Lane, Highpoint I and II, and Tottenham Hotspur Football Club.

The size of boiler you need will depend on the size of your home, how many radiators and bathrooms you have and how many people live there. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you. Other boiler types such as system boilers or conventional boilers may be better suited to larger homes because they have bigger outputs.
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.
A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.
Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.
✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.
✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.
✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.
✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer
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.
