Octopus Cosy 9 Vs 9kW Daikin Vs boiler

Mostly people don’t understand that saving many £k of capital costs can justify a lower COP, eg pay off the mortgage or invest the saved installation costs.

Running costs can be lower with a lower COP if the saved installation costs is used to increase home batteries

But the Daikins 9kw seems never to be a good option, unlike all the other heatpumps Octopus offers.
