This resonates with my friends who did it. I’ve not asked them for their spreadsheets or inside leg measurements lol.
One of my mechanical engineer friends hates it when the chemi ones call themselves an engineer; same person & posturing.

Well done. You timed it well. Things ain’t as good as they used to be.

Gas price cap is only 6p/kWh. With a circa 90% efficient boiler, that works out at 6.6p/kWh equivalent.
Little benefit in substituting gas with free electricity, or cheap overnight electricity (which can be more expensive than 6.6p/kWh!).
You should maximise selling back to the grid, and only load shed gas when you have no electricity left to sell.
