Saunier Diverter Valve (Page 2)
The diverter valve is a device 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 fact that a combi boiler wouldn?t require a cylinder to provide heating and hot water.
