There are 4 types of boiler you typically find in a domestic home, these are:

Combi Boiler – Provides instant hot water by heating up mains water through the boiler. No tanks or cylinders in airing cupboards/attics. Has 6 copper pipes connected to it.

Regular Boiler – Will typically have water tanks in the attic/airing cupboard and a hot water storage cylinder, most likely in the airing cupboard.

System Boiler – Will have a hot water storage cylinder but no water tanks in the attic. Like a combi boiler, it is pressurized, so you’ll likely see a pressure gauge in the airing cupboard or at the boiler.

Back Boiler Unit (BBU) – Back Boiler Units are built into a fireplace and are connected to a fire in front of it.
