What Are The Key Feature of A Combi Boiler?

A combi boiler, short for combination boiler, is a compact and highly efficient heating appliance that provides both hot water for taps and central heating for your home. Unlike traditional systems, combi boilers heat water directly from the mains when you need it, eliminating the need for a separate water storage tank or cylinder.

This design not only saves space but also ensures a constant supply of hot water on demand, making them popular for smaller homes. Combi boilers are energy-efficient, as they heat water only when necessary, reducing energy waste and providing convenience in a single unit.
