My only reservation is that with my cheap standard direct cylinder
("Screwfix Direct direct cylinder") the amount of hot water you get
from
it off the electric immersion is probably only enough for a shower. I
think it really needs a larger cylinder, and/or maybe an immersion
heater
mounted at the bottom of the cylinder to _reduce_ stratification when
heated electrically. Probably something like a large off-peak storage
cylinder would be more suitable.

I suspect that this will generally be a problem with immersion heaters
anyway.

If you dump heat into an indirect cylinder from a boiler at 25-30kW,
there will be considerable convection currents inside the cylinder.

Nope.

Yes.

Matt, you are stupid and should not comment on things you know sweet FA
about. Post about Makitas, that is your level.
