Condensing combi boilers help save space, heating bills and the environment
Combi boilers just got better, the new generation of space saving boilers are highly efficient at their job which in turn reduces your carbon footprint. We take a closer look to see if they live up to the hype.
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. If you want to learn more about your heating system, check out our guide to central heating systems.
