Combination (or 'combi') boilers
Combination boilers are the most popular type of boiler in the UK and are now found in around 70% of all homes.
Combination boilers provide central heating and hot water on demand without the need for a separate tank to store water which enables you to save space and means your boiler can be easily tucked away under the stairs or in the kitchen cabinets.
Benefits
- Instant and unlimited domestic hot water
- Compact, spacesaving and easy to fit if space is limited
Disadvantages
- Unable to run multiple showers or baths at the same time
- Lower flow rate for hot water than an open vent or system boiler
