Electric combination / Storage boilers

A combi boiler system is a single, compact unit that provides both central heating and hot water on demand. It combines the functions of a traditional boiler and a hot water tank into one appliance, typically wall-mounted. This means there's no need for a separate hot water cylinder or cold water storage tank, making it a space-saving option, especially for smaller homes. 

What is the difference between a storage boiler and a combi boiler?

Unlike a standard combi boiler, which heats cold water directly from the mains supply, a storage combi boiler has an internal hot water cylinder, allowing it to meet higher demand for hot water. In situations where multiple outlets require hot water simultaneously, storage combi boilers excel.
