shower bar mixer not producing hot water

hello all, happy new year!

i hope i have posted this in the right section

i have a shower bar mixer. the shower runs luke warm. a quick google search showed some ideas on how to adjust it. i tried adjusting it and it didn't change the temp. when i adjusted it the other way to test the cold, it was freezing cold. i wanted to find out how to get it hot. as an FYI, all other water facilities run piping hot, from kitchen sink to hand basins. this is the only one that doesn't. also i felt the inlet pipe of the bar mixer and that was hot. so it must be the bar mixer. any ideas on how to adjust

thanks

hi Shaun, i think i worked it out. something in the back of my mind went PING! and i went back to the shower to try something. when i let the shower run, like above, i placed the thermometer at the top of the shower head to get that reading. it reached 41d + and then the thermometer went off the scale! just like the hand held. the operative word in this is "rainfall!" as the water is falling its losing temperature. I was measuring it around lower chest height. the shower head is around 6ft, and i'm 5 8". so my lower chest is roughly 5ft. as the rainfall shower is not a "jet" like a handheld it is not going to be piping hot and has a distance to fall. i know it sounds "out there" but it must be that. so shower is correct, temperature is correct. How does that sound?

I've just read your thread. Most decent quality thermostatic shower valves can have the hot temperature increased slightly, normally by removing a handle and moving it on the splines, there should be details in the fitting instructions or online. Victorian or Victoria plumbing are terrible quality, cheap Chinese that looks good in an advert!
