Basically even with a full tank of hot water we only get hot water out of
the tap and the mixer shower with only initially let out warm water for max
8 seconds then stay cold.

I'm no expert and am hoping some one may know why and how to fix it before
its call the expensive plumber time.

Is the cold fed from the same source as the hot, ie the header tank?
If the cold is fed from the mains and the hot from the header tank
via the hot water tank, then the cold will be at much higher pressure
than the hot and will dominate any water flow.

Unfortunately, the fix is to call a plumber to run a length of pipe
from the header tank to the cold tap (unless this is a job you are
capable of doing yourself).

Was it working OK previously?

Is it thermostatically controlled or not?

hot and cold pipes reversed and the anti-scald protective thermostat
shutting down the flow?

Funnily enough a friend of mine just described the same problem and
also he is experiencing the same symptoms on a non thermostatic mixer
tap/ shower. His is pumped though with hot and cold from tanks. The
only thing I could come up with was a problem with the cold water
supply to the hot tank.

Did you get yours sorted. What was the solution.

Thanks
