The home heating system is amongst the most important parts of your own home. Your central heating boiler will provide 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 warmth through the year without a problem?
But wait, how pricey are your energy bills? Do you know upgrading your boiler can save you over £300 annually on bills as a result of enhanced efficiency? If your central heating boiler is in excess of 10-years old, then the chances are there's a massive saving to make.
Nevertheless, paying for a new central heating boiler isn't the least expensive of house improvements. It's not the most expensive either, and you could be looking at between £1,500 and £2,000 for a very efficient combination central heating boiler.
To help beat this initial cost you can consider boiler finance. With finance you'll pay back a month-to-month fee for however long you choose to cover the cost of the boiler. This might be as little as twelve months and of course helps those who can't pay the total one-off payment.
In case your boiler breaks down all of a sudden also, you might like to think of boiler finance without the funds readily available in the bank. Boiler finance is perfect and although there's a small interest charge, it's a convenient 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.

When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!
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 your boiler is making strange noises or smells, or doesn’t seem to be working properly, it may need replacing. Boilers usually last about 10-15 years. Even if your boiler is working normally, it’s worth replacing when it gets this old. An annual check will establish if there are terminal problems with a boiler that cannot be fixed.
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
