to use electric immersion heater when the sun shines
and save on FIT electricity bills, is this a good idea?
and can anyone spot a difference between

That's far too much money though it's a good idea. I posted about a
similar thing myself a week ago-ish.
How long would it take you to recover? Probably never would.
As per above,wait for the price to come down.
Meantime look at the weather forecast & just use an ordinary plug type
timer.

£30 is "too much" kin ell is your profit margin really that tight?
