I have a Gainsbourgh 9.5sc shower uniy, and in the last few months I have noticed, that I have to turn the temp dial way up to get a hot shower, where previously I only had to turn the dial just over half way...
I there anything that I can to to get the water temperature hot again?
other than that the shower is working ok..lol
any help would be much appreciated.

cheers

I've seen the same. It's a summer/winter thing.
The shower works from your cold water supply (direct from mains or from a header tank in the loft), and heats the water with its fixed 9.5kW of electrical power. If the water supply's colder, then so is the water coming out of the showerhead, so you have to slow down the supply (turn the dial towards hot) to get the temperature back.
The solution: wait for summer.
