I have a bath mixer with shower facility which works off a combi boiler - water gets too hot when someone turns on a cold tap elsewhere in house. I would like to fit a thermostatic mixer valve onto the pipework supplying the shower, can someone explain how these are plumbed in ? They seem to have two inlets for hot and cold but only one outlet for mixed . Does this get plumbed into hot tap ? if so does the cold have a direct supply separate from that supplying the valve? I have looked at a manufacturers fitting instructions but they don't appear to be as basic as I need. Any simple explanation gratefully received.

As far as i'm aware it doesn't need a dedicated cold supply, It just needs the cold to callobate to the required temperature. This then will be the supplied to the hot outlet as you have stated.
I've only ever fitted one of these and it was years ago, i can't remember exactly how i did it now

If someone turned on a HOT tap, you'd still freeze
You need a thermostatic shower mixer, which would chop the flow if necessary.
it would work if you set thermostatic valve say at 40c, and just open the hot water tap to take shower
but the benefit of replacing it with thermostatic bath/shower mixer is that you can control the temp from the bath mixer instead of having to go and under the bath to control the thermostatic valve
