There are a few on the market. I have installed some Immersun and I believe the sums do add up for them.

About £350-450 + installation + VAT, so I can't see it being cost effective. (Not to mention the highly questionable ethics, if you are receiving FIT payments.)
Someone receiving FIT payments would hold the view that ethics is somewhere to the North East of the Thames estuary.
The problem is that you have insufficient hot water capacity to store significant amounts of power.

I'm fed up of financially supporting mortgage holders and banksters. So I feel perfectly entitled to FIT payments.
You can certainly readily get a "3 phase" one with three, 1 kW elements. When you get inside the cap you will find three separate elements.
Lots of immersions of different sizes here:

'm sure they have a 3 x 1 kW (sorry, problem with Acrobat so can't open it to check)
