What Is a Combi Boiler?

What is a combi boiler?

What Is a Combi Boiler?

A combi boiler (short for combination boiler) is a compact, all-in-one heating system that provides both hot water and central heating on demand. Unlike traditional systems, a combi boiler:

✔️ Heats water instantly as you use it—so there’s no need for a storage cylinder.
✔️ Connects directly to the mains water supply, eliminating the need for a cold water tank.
✔️ Saves space, making it ideal for smaller homes or properties with limited storage.

Since combi boilers only heat water when needed, they are highly energy-efficient and help reduce running costs. However, for homes with higher hot water demand, a system boiler or open vent boiler with a separate hot water cylinder may be a better option.


Is a Combi Boiler Right for Your Home?

For small to medium-sized homes, a combi boiler is an excellent choice due to its efficiency and space-saving design. However, if your property has multiple bathrooms, you may want to consider a system boiler or regular boiler instead. Compare different boiler types at Which?


How Does a Combi Boiler Work?

A combi boiler takes water directly from the mains supply, heating it only when needed. This reduces energy waste, making it one of the most efficient heating systems available. Learn more about how boilers work at Energy Saving Trust.


Benefits of a Combi Boiler

High Energy Efficiency – A-rated models help lower energy bills with improved performance.
Instant Hot Water – No waiting for a storage tank to refill.
Space-Saving Design – No need for a separate hot water cylinder.

Regular or heat only boiler, generally used with a hot water cylinder

What is an open vent boiler?

An open vent boiler, also called a regular or heat-only boiler, provides reliable heating for homes with a traditional system. The open vent heating system usually comprises of the boiler, a hot water storage cylinder and where required a feed and expansion tank in the loft. Open vent boilers can consistently supply hot water to a number of taps at the same time. They work well if you are replacing an old open vent heating system, and are ideal if water pressure is low in your area. Open vent boilers are also compatible with solar water heating and heat pump systems for a lower carbon footprint and lower energy costs.

System boiler range

What is a system boiler?

System boilers store hot water in a cylinder, and their built-in components remove the need for a cold water feed and expansion tank in the loft. They provide a constant supply of hot water to multiple taps at the same time. Without a loft tank, system boilers free up space and reduce the risk of leaks or frost damage. They also work with solar water heating systems and heat pumps, making them a great entry point into renewable heating solutions.
