Renault #HydrogenSoufflé commercial vehicle edition.

Incredibly predictable, at least some realism seems to be being expressed at CEO level from a major auto manufacturer now, shame the funds weren't invested in their EV platforms.

Shifted tariff to Octopus Go (8.5p/kWh 0000-0530, 26.87p/kWh otherwise). Heatpump running mostly on cheap rate&solar, reduced total grid demand ~21kWh, daily costs ~£5. ~4p/kWh heat, cheap running costs. Combination of PV/battery/tariff/heatpump is impressive. Average ~3.63kWh solar/day (22 days).

I'm impressed with the Tesla Powerwall's algorithm. It is a little frustrating to have such little automated control of it in the Tesla App but using the Netzero app (www.netzero.energy) you can tell it to switch between Self-Powered and Time-Based Control (uses time of use tariff data given to it).

@duncanlamont2.bsky.social I think you have an impersonator duncan-lamont .bsky.social (without the space), he follows your followers and reaches out in DMs (presumably to scam) reported account.

Solar production over 9 and a bit days is 26.15 kWh, averaging > than 2.6 kWh for 3.87 kWp system in mid to late January at 58.47N, production more than covers heat pump demand in Octopus Cosy peak period (via Powerwall) & approximately almost 10% of overall household demand during the same period.

Neat feature of the Tesla Powerwall 2 is Storm Watch grid charging, even without the DNO approval in place it grid charges (not normally possible) when Storm Watch is active. Period is 0600-2359 tomorrow. DGAF about peak rate, £2 for ~5 hours potential off grid heating feels worth it.

Heat pump installed 40 days ago, running well during briefly sub zero weather. Powerwall 2 installed last week along with solar (~3.6 kWhp). Solar generation covering all Cosy peak tariff (4pm-7pm) heat pump use in January (@58.47° North) since operational, admittedly mostly mild temperatures so far

8.5 kW R32 Ecodan installed 12/12/2024. Replacing resistive heat, mainly mild outside temps. Average flow temperature ~35C. Ecodan reported COP 2.63 (163kWh in, 429kWh out). Massive improvement in thermal comfort, house demand costs probably closer to 40% with Cosy, ~£7.3/day last 5 days.

My mother's home hit a daily electrical demand of 101 kWh in 24 hours (90% heating?). Met station temp avg ~1 C, 15 mph NW wind.

Poorly insulated timber frame house (~142 sqm) with electric heaters. A previous surveyor recommended a 11.2 kW heat pump, curious if 8.5 kW would be enough?
