What is a combi boiler?

Combination boilers have been increasing and increasing in popularity due to their space saving design. The boiler supplies heating and hot water in one and as such do not require a water tank or a hot water cylinder. They heat water on demand, straight from the incoming cold water mains supply. Combi boilers deliver instant, unlimited hot water and are a good choice if you enjoy a long shower with good pressure and flow rate.

Without the need for hot water cylinder or cold-water storage tank and that most can be installed easily within a stand kitchen cupboard and that you no longer need to heat water that you may not use combi boilers have taken the lion’s share of the UK boiler market in recent times.

One thing to consider before choosing a combi boiler is the lack of a backup hot water cylinder with immersion heater. If the boiler breaks down you won’t have any heating or hot water. Also, if you have a large home with several bathrooms, a combi boiler is unlikely to be able to meet your hot water requirements.
