Does anyone know why my SIME FRIENDLY FORMAT 80E combi boiler will only give us hot water while the central heating is on?
If the heating is off, then water is cold.
the divertor valve is not working correctly you do not stay weather boiler comes on when you have hot water only on if not it could be the diaghram requires replacing only if it does the divertor valve will require replacing you can fit service kit but valve not expensive
