Or better still, in front of it!blueblob said:well done crafty....
I think that the diagram should hang in the TATE next to EMINS latest masterpiece of an open tin of sardines....

The saga continues..
I bought a 7.2kW shower......on a 6mm cable...double socket switch..to Consumer unit with RCD on a 30 amp...
I turn the shower on set the POWER SELECTOR SWITCH on HIGH sitch the shower via water control knob & turn anti clock wise from star to about
9 O`clock mark...the water comes out hot...weeee hheee....
But not much of a water pressue.....if iturn the WCKnob around to 1 O`clock the water comes out fast but cooler to cold.
any idea what I can do to increase my water pressue so that the water comes out if such force that if it hits my eyes I will end up looking like a panda...er sorry got carried away there!!!

Turning any tap/stopcock does not effect the pressure at all, just the flow unless you turn off completly of course. The only way to adjust the pressure is via a pressure reduction valve.
Pressure of water in your cold water pipes is dependant on the water authorities system pressure at your point of intake only.

bluebob, this time of year, think about it, the incoming water is freeeezing, so you are not going to get top notch performance out of your shower, as the water has to flow slowly thru the shower to heat up sufficiently.
also, 7.2kw is not very powerful at all, and our 9.5kw shower struggles to give enough pressure at a "just right" temperature, this time of year. Summer, it wacks out hot water like no tomorrow. You will have to find a balance between pressure and temperature, im afraid.

you do the maths (I=P/V) 7200/230 = 31.3amps, you might get away with it, but the MCB will run warm and might trip after, say, 10-15 mins constant use.
Just wait for summer . . . your shower will belt out lovely warm water

Then please stop messing with your electrics - it's not a suitable task for someone who is too thick to do very basic maths.blueblob said:Crafty it is very important that you realise that I iz fick!!!!

Or a shortcut instead of all the above: click this.
Calculate your shower rating as KW (Max stated) divided by 240 for actual amps. 230 is just the notational voltage but in practice it has not changed nor will it in the forseeable future.
Most manufacturers now quote both 230v & 240 v figures so the highest one you see say 7.2KW is at 240 volt.
Static pressure is dependant upon supply,
Running pressure is really flow.
