When it comes to buying a new boiler you want to choose one that fits your needs as it’s not a one size fits all and there are a few things that you will need to consider.
You may have already done some research of your own and found a mind boggling amount of information. You may have come across condensing boilers and non-condensing boilers but what does this mean? Put simply it is the way the boiler is programmed to use fuel when it comes to heating your home.
As of 1st April 2005, all new gas boilers fitted in the UK had to be condensed. The change in regulation means non-condensing boilers are not allowed to be used for new installations. Condensing boilers are mandatory for new installs and must use condensed programming as standard.
This change means that you can guarantee that your boiler is energy efficient and better for the environment. Condensing boilers significantly reduce carbon emissions and could save you up to 1,220kig of carbon a year.
With that said, you will need to choose the type of boiler that fits your needs. In this article we will give you an overview of the three commonly used boilers and also take a look at the pros and cons of each.
The three boilers we will be looking at are:
Regular (Conventional) Boiler
A regular boiler system is often found in older homes and is fed by two tanks, which are situated in the loft. One tank stores the cold water, drawing the cold water from the mains supply. The other tank feeds the boiler system and manages any water that expands in the system after being heated known as a feed and expansion tank.
Once the boiler heats water it is then stored in a hot water cylinder until it is needed for radiators or domestic use.
In general, modern homeowners choose to replace their regular boiler with a system or combi boiler due to the higher water pressure that they deliver. It’s worth noting that some older properties may not have the pipework needed to cope with higher water pressure and will need to stick with using a regular boiler system

Combi can be a great choice if you are wanting to save space, they are also one of the most popular choices in the UK. They account for over half of domestic boiler installations each year.
Combi boilers are ideal for smaller properties and those that have no loft space or airing cupboard like a flat or house conversion. They work by heating water directly from the mains, so you won’t be needing a hot water storage cylinder or cold-water tank. They are also very energy efficient and affordable to run as there is no unused water being stored, so less gets wasted.
Although combi boilers have some great advantages, there are some considerations to be made before going ahead with an installation.

A system boiler works in a similar way to a regular (conventional) boiler, the main difference being that it does not require a feed tank or expansion vessel to be kept in the loft as the technology is built into the boiler unit itself. The boiler takes its cold water supply directly from the mains, heats it up and sends it to a hot water cylinder to be stored until it is needed.
