What is a Combination (Combi) Boiler ?
Accounting for over half of new boiler installations high efficiency condensing combi boilers are a great space saving solution to that of a regular or system boiler.
Combi's work by heating hot water on demand which removes the need for a hot water tank in the airing cupboard, this provides good efficiency in smaller properties as the water is only heated as and when required.
A conventional boiler will require a cold water tank in the loft, combi boilers take their feed direct from the mains supply which saves yet more space, no hot or cold water tank, as a result of this less pipework is required which generally results in lower installation costs.
A combi boiler also handles the central heating system, hence the name, Combination boiler.
When Should a Combi be Used ?
It's important to seek professional advice on which boiler is best suited to your requirements.
In general a Combi boiler is a good choice if you live in a flat or wish to convert your loft into a living area.
If you have more than a couple of bathrooms or mains water pressure is low then a regular/conventional boiler is probably more suited, but remember, get professional advice.

Are They Any Good ?
As you can see in the table above the benefits far outweigh the disadvantages and will continue to do as long as the combi boiler continues to perform to a high level, at a reasonable cost.
This is the reason it's installed in over 50% of domestic households. It doesn't suit every household and if you do have space for tanks then a regular/conventional boiler may be more appropriate.
