What Is a System Boiler?
A system boiler provides heating directly to radiators and works with a separate hot water cylinder to store hot water. Unlike traditional heat-only boilers, system boilers do not require a cold water tank in the loft, making them suitable for homes where loft space is limited or where a sealed heating system is preferred.
