Different types of boiler explained
Combi Boiler
The highly efficient, condensing combi or combination boiler is an ingenious space-saving idea and a popular choice in UK homes. The biggest difference between a combi and other types of boiler is its ability to eliminate the need to store hot water.
It is both a high-efficiency water heater and central heating boiler, combined - hence the name. Located in one compact unit, which usually sits in the kitchen or utility room, there’s enormous space saving benefits from the lack of a hot water storage cylinder or cold water storage cistern.
The combi also delivers significant savings and hot water is delivered through your taps or shower at mains pressure. So you can enjoy a powerful shower without the need for a pump. And as there are no tanks in the roof space, there’s less pipe work and a shorter installation time.
System Boiler
Both system boilers and regular conventional boilers provide stored hot water - but one differs from the other in some important ways.
With the system model, many of the components are built in, which means installation is quicker, easier and more efficient. The boiler also includes an expansion vessel so there is no need for a tank in the loft, saving you space.
High Energy Efficient
Since April 1st 2005, a change in building regulations has meant most boilers must be high-efficiency condensing boilers. This is the most efficient boiler model, converting more than 88% of the fuel it uses into heat, compared with 72% for conventional boiler types.
High-efficiency condensing boilers can be fitted to most new and old heating systems and are so small they can often be fitted in a kitchen cupboard. The easiest way to check if your boiler is energy efficient is by its age. If it’s between 10-15 years old then it is likely to be less efficient.
Replace it with a new high-efficiency condensing boiler and you could save you around a third on your fuel bills. If you’ve had your boiler for 15 years or more, then replacing it will avoid mounting repair costs as well as reducing your bills. If you're refitting your kitchen or bathroom, you can minimise cost and disruption by fitting a new high-efficiency condensing boiler at the same time.
