Buying a New Boiler: What to Compare

Buying a new boiler can be a confusing task! That’s why we created our handy new boiler comparison tool so you can compare up to 4 boilers side by side across a range of different features. So what exactly should you compare when looking for a new boiler? We took a look at the things you might want to consider sizing up between manufacturers and models before you make the purchase.

Fuel and Boiler Type

The type of fuel you have access to will likely be the first thing to influence what kind of boiler you buy. Gas and electricity are the most popular, but alternatives like LPG and biomass (solid fuel) are also good options to consider.

The type of boiler itself is the next consideration you might want to make. This generally falls into 3 categories: combi, regular and system. Visit our guide for more information about different boiler types.

Size

The size of your new boiler will depend on the requirements of your home and family. By knowing the correct size you can purchase the most efficient model available – rather than a too small system which can’t fulfil your needs or oversized system which wastes energy. It’s important to note that boiler size is measured in kW rather than in physical dimensions, so look out for the ‘kW options’ row in our comparison tool.

Mounting type

Wall mounted or free standing? The answer to this will likely depend on the amount of space you have for a boiler and where it will be situated. The majority of boilers are wall mounted (also referred to as wall hung) but if you have the luxury of space there are free standing options available in the UK.

Efficiency rating

Making sure your new boiler has a high efficiency rating will help you to save money on energy bills and reduce your household emissions. A new rating system called the Energy related Products Directive (ErP) came into play in September 2015 but whilst manufacturers are still updating their boiler information we’ve opted to continue showing the SEDBUK ratings until the ErP data becomes available. The ratings are split into an efficiency rating shown as a percentage (the higher the better) and a band rating assigned a letter from A (most efficient) to G (least efficient).

Price

Once you know the kind of boiler you want to buy you can start to get a rough idea of the kind of price range you would be looking at. In our boiler comparison tool you can find both a typical price for the boiler itself as well as a typical installation cost. It is important to note that this could vary a lot depending on a number of factors including the company that installs your new boiler as well as the details of the installation itself, for example straight swaps are usually cheaper.

Shopping around for quotes is one of the best ways to save money on your boiler installation.
