However in some situations a system boiler may be a much better alternative. Combi boilers are not suited for homes that have a high demand for hot water as they are only designed to support one outlet at a time. Because combi boilers typically switch the burner from heating to hot water when there is demand heating performance can also be impacted in high demand or very large households.  A system boiler in contrast features a separate cylinder for storing hot water. Although the major heating and hot water system components are built into the boiler the hot water is stored in the cylinder. This means that a constant supply of hot water can be provided to a large number of taps and showers at the same time. This makes it the ideal choice for a home with multiple bathrooms or small offices..
