Understanding the different types of boiler on the market

If you are looking for a new boiler for your home, you may already be aware that there are a number of different types available. Given that a new boiler is a large investment, you will want to make sure that you do your research and choose the right type. Let’s take a look at the three main types available.

Regular boiler

Also known as heat only, conventional or traditional, this type of boiler is suitable for homes that already have a cylinder for hot water and a storage tank for cold water. They can generally be replaced on a like for like basis without the need to remove tanks and cylinders.

They are particularly useful if your home has a radiator system that is several years old, as they deliver a lower water pressure than other boiler types. Too high a water pressure pumping through an old radiator system can cause problems.

Combi boiler

Also known as a combination boiler, this is one of the most energy- and cost-efficient types of boiler on the market, supplying both hot water and heating. As they only heat water when taps are turned on rather than constantly storing a full tank, you only pay for what you use.

They can also help to free up additional space in your home, as you will no longer need the water storage tank, which is generally found in the loft, or the cylinder for hot water in the airing cupboard.

If you are looking for boiler installation Bristol, companies such as can help. Whoever you choose to supply and fit your new boiler, you should ensure that they have the appropriate certification to install your boiler safely. The Gas Safe Register enables you to check the list of registered members.

System boiler

A system boiler sits somewhere between the regular and combi boiler. You will still have a cylinder for the hot water but there is no cold water tank in the loft, so they are often installed when a loft conversion is planned. Both the system boiler and the regular boiler are suitable for use with solar systems if you are looking for an eco-friendly solution.

It is worth doing your research before you buy a boiler, with any reputable Gas Safe registered engineer able to provide further advice.
