the extra 3 kW from the immersion
Just in case relevant ...
We schedule our immersion to start latest possible time, during Off Peak, to be certain to complete by end of Off Peak. So that the water will remain hottest for when we get up, and not heat-early and then potentially "top-up-a-bit" later on in the night.
That might avoid the car charging slot or, worse case, the car would have plenty of time to charge before it then drops out as the immersion comes on stream, so you'd have "some charge" is that happened.
