The water flowing from my power shower is too cold/cool, what should I check?

Check that the hot water temperature at basin taps is acceptable this should be approximately 55 to 60C. If it is not, then the thermostat on the hot water cylinder needs adjusting. Is the water temperature acceptable by pressing the 'maximum temperature stop' override button, and increasing it to a higher setting? If it is then adjust the 'maximum temperature stop' as per the fitting instructions. Ensure that the inlet filters are not blocked. Check that air has been purged from the pipes up to the inlet elbows (as per the fitting instructions).
