What is a Combi Boiler?
A combi (or combination) boiler heats water instantly when you turn on the hot water tap. It does not require a separate hot water cylinder to store heated water like conventional boilers. Combis provide hot water and central heating in one compact unit, making them popular choices in many homes today.
How Combi Boilers Work
Combi boilers utilise an internal heat exchanger that rapidly heats water straight from the main water supply as it flows through the system. This on-demand design means you don’t have to wait for hot water like with traditional boilers. Most combis today have improved efficiency levels, helping save on energy usage over time.

Combi boilers offer numerous benefits but also some downsides to weigh:
Pros

- Compact size – All-in-one unit with no separate cylinder
Cons
