Hi all,

We had a shower before that was like 7-8Kw and the presure was good and constant and now we have got a 10Kw shower and the presure is low and changes from hot to cold whenever the dishwasher is on or someone turns on the tap. I thought the higher the Kw the better the presure and even it if didn't support out 10Kw shouldn't it be backwards compatible with what we used to have? Thanks

 

Yeah i also had the same issue but it was sort out just be replacing the old one with the new one.

your shower is temperature/pressure sensitive - when the pressure goes down - ie when somebody uses water from the cold mains the sensor turns off the heater as the reduced amount of water flowing would be too hot and it might scald you.....it's an anti-scald device

I have a problem with shower head size, my shower 24 kW from gas boiler needs a minimum flow for boiler to run, and due to that I have learnt not all shower heads are the same. If the holes are too big you lose pressure, and too small you lose the volume so shower head needs to match shower.

I looked when doing my shower at the idea of size jets, but my boiler is not big enough need around 35 kW for side jets.

I really hate when on holiday having to use electric showers even the best seems like a dribble compared with one at home.
