Baxi 5111140 DHW Diaphragm Repair Kit - Max & Combi Instant - 1117798DHS

Product Description

This component is located within the diverter valve assembly. The diverter valve is a key component found in combination (combi) boilers and is responsible for directing heated water either to the central heating system, such as radiators, or to the domestic hot water supply for taps and showers. This allows a combi boiler to provide both heating and hot water on demand from a single appliance, removing the need for a separate hot water cylinder in most installations.
