The different types of boiler in a nutshell

As this is the first post regarding boilers on this blog, I thought it would be a good idea to start with a background on each type of boiler that is most commonly found. This is one of the most confusing elements for people looking for a new boiler and we have been asked questions time and time again on the differences between them.

To help save you money in the long run, it would be better to help develop an understanding on the different types of boilers. From here, this will hopefully help to influence your decision on the type of boiler that would be most cost effective for you.

The three most commonly referred to central heating boilers are:

Condensing Boilers

Condensing boilers are one of the newest types of boiler you will find, and when replacing one for a new household they have been compulsory designed by the Building Regulations as a replacement.

Condensing boilers consume small amounts of gas making the most of the energy that they consume, whereas compared to some non-condensing boilers which are the complete opposite.

Overall this type of boiler will consume a lot less gas and still provides the same amount of heat that a non condensing boiler would provide.

Combination (aka Combi) Boilers

This type of boiler is often mixed up with condensing boilers, but they are both unrelated. The Building Regulations requires a condensing boiler to be installed, whereas with combi boilers they are not required.

As you turn the hot tap, water passes straight through the Combi central heating boiler where it is heated by gas flames on the go. When compared with conventional boilers which heat a tank of water and store this for later use. This results in not only heating water which may not be used, but more importantly it would cost more money to heat a tank than to heat on demand.

Combination boilers are also extremely easy to fit and in most case a lot cheaper too when compared to the conventional types of boiler.

Conventional (Regular) Boilers

These refer to non-condensing boilers, but the term ‘regular boilers’ has only been used recently as most boilers were non-condensing.
