Electric shower advice

[someonelse]

My mum's shower's playing up. Triton. Seems to be an electric, fed by cold water only.

It comes out cold. Turn the stat up and just as it reaches 'max' it clicks on then comes out boiling. Turn it down and you have to turn down a long way before it clicks, then freezing again.

I'm guessing a faulty thermostat? If so, can they be replaced or is it a new shower unit?

If not, could it be that the cold supply is just too cold for the stat to handle? If so, recommendation for a better unit?

I've also seen references online to elctric showers which have a 'summer/winter' switch. What are these and how do they work?

thats the symptons of a faulty stabiliser valve.
to check the valve remove head turn to fully cold the flow should be powerful then turn to fully hot the flow should gradually reduce down to a trickle.

Many thanks.
Mum found a leak in the supply pipe outside - temp fix in place and shower now fine.
Low water pressure!!
