New thermostatic bar mixer temperature fluctuation ?

Run the shower and check temps at the same time check the hot output from the boiler if the boiler temp is fluctuating from very hot to cold it may be the shower is not set up for enough water flow there is some times graded washers that are fitted in the inlet side to adjust for different pressures/flows etc

Hiya, yes it`s a standard thermostatic bar shower if there is such a thing, and the hot is on the left as it should be as is the pipework, thank`s.

Is the mixer designed for combi boilers or have you got the hot and cold inputs orientated correctly,not all shower mixers are the same
