No hot water! I've searched the forum

[syrup]

Hi,
I know this has been brought up many times but I cannot find a cure after searching the forum!

I have a Worcester Bosch oil fired boiler that is regularly serviced. The problem I have is that the central heating is fine but there is no hot water!

The pump is working fine (I'm not sure that is relevant for the hot water) I have a Honeywell two port motorised valve that has two positions, open/manual and auto, I have tried it in both positions to no avail. The header tank in the loft is working fine. There is a bleed pipe in the airing cupboard where the hot water cylinder is, if I undo this nothing comes out, air or water!

Everything was fine yesterday, the only thing I did was bleed a couple of radiators!

Any help greatly appreciated.

There may be another motorised valve somewhere that controls the hot water. How many pipes come from the boiler?

I've enclosed a picture, sorry it's so big!
There is one pipe coming from the boiler going to the pump, it is hot going in and coming out! The corrosion has been there forever!

As you can see there is a pipe coming from the ground going to the valve, this is also hot coming in & going out.

I've searched everywhere for another valve but cannot see one!

Thanks!
