What is Combi-Boiler?
A combi-boiler, or combination boiler, is a highly efficient heating system that provides both central heating and hot water on demand, without the need for a separate water tank. Unlike traditional systems that store hot water in a tank, a combi-boiler heats water directly from the main supply whenever it’s needed, so you get instant hot water for showers, faucets, and household appliances. This dual functionality makes it space-saving and ideal for smaller homes, as it combines heating and hot water into one compact unit. Combi-boilers are popular for their energy efficiency, easy installation, and ability to reduce heating costs.

A combi (combination) boiler is designed to heat a building, using hot water (similar to a boiler), but also includes the components and controls to internally heat the domestic hot water (DHW) required in the application. By having both heating and hot water in one unit, the combi will save space in the mechanical room and also save on the initial installation compared to separate appliances.
