I'm thinking getting immersion fitted this year.  I would imagine work out price per kw and hours run and put a rough figure in?

I do this for running pumps/heaters etc on ro and put a small amount through the books. My accountant is ok with this..

Next question, any reason not to mount the element vertically? Obviously the tank would need to be full but a 27" element would be a lot easier to mount from the top instead of drilling near the bottom and fitting an 11"?

As long as it is fully submerged I can't see a problem.  Some airing cupboard tanks have top mounted elements ..

All the heat is going to rising straight up - that's a lot of heat in one spot for a plastic tank.

With it at the bottom (ish) your heating a lot of water before it reaches the top of the tank

Good point - metal flange might get too hot.

Would 11'' be enough for 650L?

Domestic hot water tanks are either gravity or pressure fed which means they are constantly full. As soon as water leaves at the top it re-enters at the bottom. Also the water level is always higher than the element as it rises through the exit pipe at the top of the tank plus the top of the tank is cone shaped with the element located lower and to the side of the "peak". This is why some DHW tanks have top fed immersion elements. You would not recreate those circumstances in a WFP tank.
