Very short notice - almost missed this one myself!
@octopus.energy customers, opt in to earn Octopoints and help to take some load off the grid during the peak this evening.

Charging the home battery, boosting the ASHP for some extra space heating, popped the immersion on for extra hot water, and got the oven doing a pyrolytic self-clean.

🚨 #SavingSession alert 🚨
Seems a little odd considering the amount of wind we’ve had lately, the session being outside of the usual evening peak, and the Agile pricing not crazy at the time. Maybe it’s a test 🤔

Just finished reading ‘Frank & Red’ by Matt Coyne a.k.a. Man Vs Baby. Wonderful heartwarming story. I cried. I laughed. I cried some more. Very much recommended.

650% efficient hot water run - best I've had yet, but will likely only get better as the weather warms up 😎
Only very slightly flattering as I don't have every electrical input monitored, but a great result compared with my own overall average hot water COP of 362%.

Woop - just shy of 600% efficiency with the hot water run this afternoon, with all the electricity consumption coming from the solar PV. Nice to have the warm afternoons and sunshine back :)
