And if I have cocked up and the thing is suddenly costing me a fortune, then I can start a new thread.
Bear with me here because it's a long long time since my Physics O Level and I don't promise this is accurate but Assuming 100% efficiency, no losses anywhere to keep the sums straightforward and assuming a starting water temperature of 18c and bath temperature of 45C then an 80 litre bath will take around 9,072,000 Joules to bring it up to temperature, whatever method is used to generate those joules. A 40litre (5minutes ish) shower will take 4,536,000 Joules to reach and maintain the same temperature. 9,072,000 Joules equates to 10.5KwH 4,536,000 Joules equates to 5.3Kwh So I'd be interested to see the figures in 6 months because if you are getting what you seem to be then there's a big energy hole somewhere.

Excellent , will it be a you were right I’m eating humble pie Or up yours I’m in the money As we will get this green stuff forced on us it will be good to know
I have been following this thread with interest, and some amusement. On the one hand there is an experienced professional, an expert in the field, who helpfully supplies real facts, accurate figures, and valid arguments based on the laws of physics and the commercial realities of energy markets. These are supplemented by links to e.g. numerous examples of false advertising by the (unfortunately named) Fischer. And on the other hand, there is waffling, blithering, vagueness, unsupported assertions, facetious sarcasm, and refusal to accept reality. It all reminds me of Brexit. Or religion.
As @PerryL has provided real factual data on energy usage since his new system was committed, I consider your comments about @AirCon to be rather harsh!
