Some platform engineering dude, getting a little bit obsessed with his kilowatt hours!

Cycle to school week is imminent. As a parent who already cycles the sprog to school, I hope that week involves less cars overtaking too close, opening doors on me, overtaking on a blind bend and adults crossing the road without looking. Unfortunately all 4 happened to me TODAY.

Never been to a dedicated EV service station before. Clean, calm, well organised. Probably won’t last once EVs become more the norm.

A seemingly random farm with a shop and a café with beefy chargers in Norfolk. Not a bad place to find yourself needing to top up ☕️⚡️🐄

Let’s start the countdown again. Cables replaced in Mackworth, how long until the drooling knuckle draggers return to Nick the cables? I think last time it was 9 days?

Time. It took about 9 days. I think they got interrupted in the process…

The charger cables in Mackworth, Derby have been replaced yesterday by BP Pulse after having the cables cut by knuckle dragging, mouth breathers. How long will they stay this time? Got to beat the record of 4 weeks…

The summer of effectively free electricity, heating and car fuel is over and we’re now deep into the (at present) -4°c winter. Happy to report we’re still toasty warm inside. I’m collating the data for cost saving over the year.

Parked up at a hotel and every time I open my boot I am ambushed by swans and geese. Is this normal?!

In honour of my Twitter profile’s pinned tweet about people who like bitter coffee…

1 MWh in, 3.24 MWh out since our heat pump install. Toasty warm. Not quite at the 3.4 SCOP but most of the operation has been in February and March so we’ll see what it looks like in a year’s time.

The results of a full month of Solar + Heatpump are in! March 2025 cost £58.30 for electricity, heating and car fuel. If I had my MPAN set up, I probably would have only paid £33.57. Can't complain.

I love sunsets with clear skies around the equinoxes. I can’t put my finger on it but I just want to be sat out watching the light fade with a beer.

I’m in the nice situation today where I’ve got so much energy available that I can’t store it. So I turned on the dishwasher, the washing machine and mowed the lawn. An hour after finishing I have a full battery again. I may need to charge the car now 😀

I’m loving the sunshine right now…

Yesterday was a £0.04 / kWh kind of day. I can’t complain at that.

There we go! Too much energy to store now 😅

It’s still February and I’ve basically filled my 10kWh battery with energy from sunlight. I think that justifies me expanding my capacity in future 😉

Probably the last electrification post for a while, but because our Solar panels have been commissioned today, it's the last day of data for the estimated savings from the heat pump alone. Obviously a lot of factors involved that might muck up the numbers but it looks like it is saving us money.

Batteries in, panels up, switched on and producing! My heating this afternoon is powered by sunlight (and whatever charged the batteries to 25% before they arrived).

Panels are here, rails are up on the roof, batteries are being installed. Lots of progress today! I would be excited, but I’ve found out my EV charger is no longer compliant, due to poor wiring and CT clamp placement. There’s an unexpected cost! Looks like I need a MyEnergi Eddi.

And the work resumes, scaffolding now up for the solar panels!

Heat pump at full tilt (engineer test mode). Please excuse the silly “full powah” comment 😅. It’s quieter now, can’t hear it indoors at all, even though it’s 3°c outside. I’ll be interested to see what it’s like when it drops below freezing.

Day 4 of climbing up the EPC ratings, the heat pump has been wired up and plumbed in, the system filled with water and tested at full tilt. Now after 3 days with no heating (1-5°c outside), the house is slowly becoming nice and toasty again. Pausing now until end of February for Solar install!

Day 3 of boosting our EPC rating, the heat pump is wired up and plumbed into the hot water cylinder. Still some lagging required externally and the heat pump controller isn’t yet wired up, but we’re close. Heating should be turned on tomorrow! 🎉

Day 2 of upgrading our EPC rating and we’ve gained a cupboard! Not only that but we’re no longer burning fuel in our house. We’ve offloaded the burning responsibility to the grid, which over time should be getting greener. Heat pump not yet operational (PTC and jumpers tonight). Hot water is on!

Day one of increasing our EPC rating and the Cosy 6 (Dalek) is wired up and on the plinth. The scaffolding is a little bit misplaced so no plumbing yet, hopefully this will be rectified soon so the system can be drained, the new cylinder installed and the gas boiler decommissioned.

So my front door lock is broken from the outside (I think there’s some dirt/debris locking a pin out of place). Totally not a good look to be using picks to test the pins are moving. No luck.
