Pressure on a thermostatic bar type shower.

slaphead · 4 Sep 2007

Fitted a thermostatic bar type shower for my mum, don't know the make (from Lidl) works fine in my house (combi boiler&mains cold) but get rubbish pressure at my mums (gravity fed hot and cold). I have read something about these not liking tank fed cold water. Can anyone enlighten me ??

Probably made only for high pressure systems and have a smaller internal bore which is restricting flow.

Thanks for that, i will see if they sell different ones elsewhere.

otherwise you could fit a shower pump. shower mixers area bit expensive to buy on trial and error. British taps and showers are obtainable to suit low-pressure British supplies. Imported ones (mostly Italian) usually aren't.

What is the height difference between the bottom of the cold water tank, and the shower head? I have one with about 4metres head which gives a fair shower, and one at 10 metres head which gives a good shower.

It helps to have a shower head with big holes in it to get better flow.

The height is only about 1-2 metres but if i take off the bar and let it shoot straight out it has good pressure. I think i will get an electric shower and leave that in situ, i have easy acces to the main in the loft and a fairly easy route to electrics.
