Your boiler is the heart of your home. When the time comes to replace it you want to know what is the price of a new boiler to make sure you’re getting the best option for your budget.

How much difference does a new boiler make?

Although replacing your boiler can seem like an expensive home improvement, you can save yourself considerable money that can be utilised elsewhere in your home. Up to 60% of your energy costs are on heating alone, so if your system isn’t effective you could be spending unnecessary amounts to keep your home warm. When boilers age, they can become less effective and, therefore less energy efficient. Replacing your boiler with a modern A-rated system could save you as much as £340 on your energy bills each year.

Types of gas boilers

The cost of a boiler can vary depending on the type of boiler you choose. When choosing your boiler, you should consider the size of your home and the needs you have for it. The two most common gas boiler options are;

Conventional boilers

Conventional or heat-only boilers use storage tanks to hold water, with the tank usually stored in your attic. The water is heated as and when it’s required. The tanks can take up a lot of room, and if you don’t have an existing conventional boiler, then having one installed can be lengthy and difficult.

Combination boilers

Combination or combi boilers are the most popular boiler replacement option due to their slimline design and easy installation. Combis don’t have storage tanks which is why they’re so compact. Combi boilers work by heating the water when you need it, and, despite their size, they can handle a fair amount of water.

Which boiler is right for me?

If you have a larger home with two or more bedrooms, a conventional boiler could be the right choice as they can heat much larger areas due to their water storage tanks. Conventional boilers can also provide hot water to multiple taps simultaneously, meaning someone can run a bath upstairs whilst someone does the dishes downstairs.  Don’t forget, as they need storage tanks to work; you need the space available in your loft to install and store the tanks effectively.

Combi boilers are a fantastic option for smaller homes or flats as they’re compact and don’t require storage tanks. There’s no need to worry about their efficiency; they can still provide your home with plenty of warmth and hot water. The only negative is you can’t use multiple hot water sources simultaneously without a notable drop in pressure.
