worcester Bosch Greenstar 42 combi.condesing. Installed 5 yeras ago but not used so much as I live alone and work away. The hot water is run seldom. Central heating working fine but hot water not firing up now. I tried to find a circuit diagram so far no luck. I assume there is a flow demand sensor to signal burn?

Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
heating ok but no hot water
- Thread starter vigo
- Start date
Possibly diverter valve?
Check the pushrod is making the switch when hot tap is turned on.

Thanks John, I`ve found and printed out the complete Installation, commisioning and servicing manual and found the Diverter V and Div. V motor. Should I be checking the movement of this spindle (DVM) which I assume inputs to the DV when HW is demanded?
Thanks Tony, that`s got to be the flow sensor #15 in manual I`ve been looking for. Senses flow and sends signal to DVM which opens DV. I`ve got it now, thanks to both of you.
