And Ripple say you save typically 25% on your bill.
But at Nowty Towers its 900%.
Its not Science Fiction but its Science Fact.
Lets do another calculation,
1kWh from GF pays me 27p, and my IO cheapslot is 7.5p / kWh, therefore that gives me 3.6kWh.
COP of 3 from my heatpumps, 3 x 3.6kWh = 10.8 kWh of heat energy.
And in a recent post I calculated the cost per each kWh (to me) over GF's basic lifetime at 3.24p / kWh.

So that 3.24p (pro rata cost to me of 1kWh of GF) gives me 10.8kWh of heat energy or 0.3p / kWh.
And that can be time shifted to the depths of winter using the octopus virtual battery (VB).
So compared with someone heating water with an immersion heater on standard Flexible at 34p / kWh.
Mine is 34p / 0.3p = 113 times cheaper.
Its the green crap again.
