Electric Shower low pressure

[diyplumber1980]

Hi, I've just changed my mates electric shower, and i've noticed the pressure on the water seems to be low when he has it on a higher heat setting.

Its a Triton Shower, got it for about £90 from bnq. He lives in an apartment type building. Is it normal for the pressure to be low on an electric shower on a high heat setting. When we go for a mid range heat setting, the pressure seems to be ok.

Many thanks

Triton what ?

Do you mean when you turn the flow dial (bottom) up the flow reduces ?

Its Triton Cara Electric Shower White 9.5kw.

If i put heat dial on "high" and turn the temperature dial up to about 8, the pressure of water coming out the shower seems to go low, but if i turn the temperature down to about 5 or 6, the pressure seems ok.

This is the shower

Yes thats right if you turn the flow dial from 1 to 10 the flow will gradually
reduce down to a trickle.
Don't matter where the heat setting dial is low,med, high.

That's how it gets hotter the speed of the flow through the shower.
Slower flow = hotter temp.

bit worrying. id get a general understanding of basic plumbing first.

thanks for this. I was thinking the shower might have been faulty
