The diverter valve is a part that only appears in combi boilers.

It allows the hot water to be sent to the central heating system (radiators, etc.) or to the hot water system (taps, etc.).

This feature is what separates a normal boiler from a combi boiler due to the fact that a combi boiler wouldn’t require a cylinder to provide heating and hot water.
