If all users of immersun and similar Fit Fraud PV divertor devices switched them off, Then less coal, gas and woodchips would be burned in electricity generating plants! As a consequence you would have to burn and pay for some extra gas and oil to be burned at home.

Rather disgusting post.
If diversion devices tip somebody over the edge into getting PV, then there is a net gain with PV displacing some FF leccy and FF DHW. Anything that improves the economics of PV should be celebrated not smeared.
During non space heating periods I doubt gas boilers are achieving much more than 50% efficiency, especially after accounting for heat loss in the internal pipe runs which is now no longer a space heating benefit, so replacement leccy generation from gas at 50% efficiency would seem to roughly balance out anyway.
If there is any concern about export v's export payments then I'm sure the companies would complain, but since most PV'ers export more than 50% of generation, I somehow doubt they will want to make a fuss.
I really don't see how spreading old (very old) anti-PV propaganda helps anyone today, I'm a PV'er, with no diversion, on the low export rate, that exports approx 70% of annual generation. For May my generation was 678kWh and my export was 547.6kWh's, I will be paid for 339kWh's and I (clearly) have no issue with PV complimentary technology.
Additional note: my May consumption of leccy was 214kWh, a bit high, but due to quite a bit of ASHP use in the early weeks when we had very cold air temps. During that period when the COP was probably 3 or 4, we didn't need to use the GCH at all which is a good thing since it would have been around 5x less efficient.
