I would boost for a bath and it's been talked about a lot dishes are cheaper to boil a kettle for.

I know it seem archaic but the savings add up.

I barely have my immersion on in almost 14 yrs I've lived in this property and I used to use the kettle for wash-up water once daily but now I heat a big casserole dish of cold water in the oven when cooking dinner at same time to utilise the oven being on. Two birds with one stone. Lol.
And the water comes out the oven much much hotter than the kettle water. 

Does anybody know if you put the immersion heater on through night, does that hot water get used if you put electric shower on or does it only come through the taps? Out of interest.
I'm thinking it only comes through taps but wanted to ask in case.

It'll come through kitchen, bath and sink hot taps. Electric shower is fed by cold and heated up

Water heated in an unpressurised oven cannot be hotter than boiling water from a kettle.

Indeed it can't 

And I am not convinced indirectly heating a casserole dish of hot water in an oven that is in use anyway will save anything over heating the same volume of water in an electric kettle.

I would have thought there was more opportunity for external heat loss from the oven and wasted energy heating the dish than the losses from a modern kettle.

I've been trying to make the same point (in less detail, admittedly) over in this thread.

If you put it in the oven after its turned off then its using the waste heat... but then you want that heat in a direct electric heated house in heating season. But then if you have an air source heat pump heating the house cheaper than the oven its a win.
