Safe shopping by GeoTrustA regular boiler is often also referred to as a "traditional" or "conventional" boiler.
If you are replacing an older model of boiler, the odds are that you will have a regular boiler. A typical conventional system incorporates a boiler and extended controls, a feed and expansion cistern, and a hot water cylinder (frequently in the airing cupboard), which is often fed by a cold-water storage cistern positioned in the roof space.
