electric shower question

[phl666]

Can I change the shower head on an electric shower? Does it matter which sort I use? I tried it, but since then, the water sometimes comes out cold. It might be a stupid question, but does the head which came with the shower unit offer just the right amount of pressure resistance - or something like that?

You should be able to fit pretty much any head. There is not that much difference between the amount of water different types pass - unless you fit one the size of a dinner plate !

Might be worth looking for one which 'aerates' the water as it leaves the shower head. These give a better shower without using more water - particularly good if your are on a water meter.

I seem to recall at Homebase that replacement shower heads were marked with the type of shower they were suitable for.

Hi,   Yes it does matter with an electric shower.  They are designed to only work when the water is flowing and this is sensed by a simple pressure switch,  If the new head you fit has holes which are too large then so much water flows that the pressure in the shower unit cannot build up and it will not switch on the heaters.

You must find a head with smaller holes or less holes whatever is easier (or increase the supply water pressure, usually impossible to do).
