The Divertor Valve is also known as a 3 way valve/three way valve, its a mechanical boiler part that pushes the hot water that's produced by the Chaffoteaux boiler either to the hot tap (if there is a demand for hot water)or around the central heating if there is a demand for central heating. Note a Chaffoteaux combi boiler can only supply heat to 1 source at any one time, either hot water or central heating but not both at the same time.
