Choosing the right boiler

Baxi makes three different types of boiler: combi, heat only and system boilers. All of these products include the latest condensing technology, so they are highly energy efficient and very cost effective to run.

Combi Boiler

Combination boilers, or combi boilers as most people call them, heat water instantly when you turn on a hot tap. As the water comes straight from the mains there is no need for a water storage cylinder or water tank. Hot water flow rates are usually very good.

Is it for me?

An economical choice for most households, combi boilers are the most popular type of gas boiler in the UK.

 

 

Heat onlyy layoutHeat only boiler

Also known as a 'regular' or 'conventional' boiler. This type of boiler is often found in older homes and needs a feed and expansion tank in the loft to store cold water. It also needs a hot water storage cylinder and a pump, to pump hot water around the system.

Is it for me?

A popular choice for replacing older heating systems, heat only boilers are perfect for large properties with a high hot water demand.

 

 

System boiler 

A boiler that works with a hot water storage cylinder but does not generally need a tank in the loft to fill the system.

Is it for me?

System boilers are quick and simple to install because all major components are built into the boiler.
