What is a System Boiler?
A system boiler is a sealed heating unit that connects directly to the mains water supply and works with an unvented hot water cylinder to store and deliver hot water efficiently. Unlike combi boilers, system boilers allow multiple taps and showers to run simultaneously without a drop in pressure. With a built-in pump and expansion vessel, they ensure fast heating response times and minimal external components for a streamlined installation.
