Just in case you aren't 100% sure what a combi boiler is, or how it functions -
Unlike conventional boilers, combi (combination) boilers link a home’s central heating system and water heating.
A combi takes water directly from the mains and heats it upon usage. After detecting a hot water request, the combi begins to burn gas in a combustion chamber.
The hot gases rise and move through a series of pipes and into a component called a heat exchanger, the hot gas running through the exchanger then heats the surrounding cold water.
In a conventional boiler system, this process is done according to a programme and the water is stored in a separate cylinder until it’s needed. A combi only starts this cycle upon request (initiating the heating or turning on a hot water outlet), therefore the hot water is instant.
