Product Information: The diverter valve is a part that only appears in combi boilers. It allows the hot water to be directed to the heating system (radiators, etc.) or to the hot water system (taps, etc.). This feature is what makes a combi boiler so popular due to the diverter valve allowing use of hot water and heating without the need for a cylinder
This part is present in 4 different boilers in the Ariston range including the Ariston SX 20 20 M , SX 20 MFF , SX 20 MFFI CE , SX 20 MFFI CE .
