Glow-worm 30ci water going to bathroom not very hot Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I have a glow-wrom 30ci my heating side is working ok but when I run a bath, shower or use the wash basin the water is not very hot.
Have tried shutting valves to central heating but this has made no difference ( hot water was back feeding down this pipe).
can anybody help
