A regular boiler and a system boiler are very similar in that both rely on a hot water storage cylinder to keep a store of hot water ready for your taps. The key difference, however, is that a regular boiler is supplied with cold water via a cistern in the attic, while a system boiler takes its water supply directly from the mains.
