Common Boiler System Types
Combi Boiler
Heats water on demand with no need for a separate tank or cylinder — popular in smaller properties.
System Boiler
Works with a hot water cylinder, drawing water directly from the mains — suited to homes with higher hot water demand.
Conventional Boiler
Uses a cold water tank and hot water cylinder — common in larger properties with multiple bathrooms.

⚠️ UK Legal Requirements — Boiler Installation
New boiler installations must comply with Building Regulations Part L (energy efficiency) and Part J (combustion appliances). All gas boiler installations must be carried out by a Gas Safe registered engineer and must be notified to the relevant building control authority. Since April 2005, new boilers in England and Wales must be condensing boilers unless there are exceptional circumstances.
