What is a Combi Boiler and How Does it Work?

What is a combination boiler?

A combination boiler, commonly known as a combi boiler, provides both central heating and instant hot water directly from one compact unit. Unlike traditional systems, combi boilers don't require separate hot water tanks or cylinders, making them ideal for smaller homes or apartments. This type of boiler is efficient, space-saving, and delivers hot water on demand whenever you need it.

How do combi boilers work?

Combi boilers heat water directly from the mains supply when you turn on your tap or heating, eliminating the need for storage tanks. When hot water or heating is requested, the boiler quickly ignites a burner to heat water instantly and deliver it throughout your home.

Is a Combi Boiler Right for My Home?

A combi boiler is ideal for homes that require efficient heating and instant hot water without the need for extra storage space. It's particularly well-suited to small or medium-sized properties with one or two bathrooms and good mains water pressure. However, if your household has higher hot water demands or multiple bathrooms used simultaneously, you might benefit from a system boiler or regular boiler instead.
