MIRA Sprint electric shower issue

[jeronimo917]

I have a problem with the MIRA Sprint electric shower in my house.
When turning the water to cold the shower works perfect, pressure is brilliant. When I turn the water to warm the pressure drops significantly. I already took the shower head and hose off but that did not make a difference. Any suggestions?

naturally this is how an elec shower works, by slowing the flow the water is 'heated up' for longer and thus is warmer

The process should be better on the higher power setting as both elements will be on then

Can you feel a temperature difference between the two power settings?

turning the water towards warm/hot will decrease the flow because the water has to be slowed to allow it to be heated by the heating element.
