Ariston Diverter Valve (Page 5)
The diverter valve is directional water mechanism that only appears in combi boilers. It allows the hot water to be redirected to the heating system (radiators, etc.) or to the DHW system (taps, etc.). This feature is what makes a combi boiler so popular due to the fact that a combi boiler wouldn?t require a cylinder to provide heating and hot water.
