That why you have a dirty big hole in your back alley now. If you can't go up, go deep down.

Couple more charts for anyone that is interested. Hourly demand as a percentage of daily usage and actual energy demand in GWh. This may be useful if you pay on a variable ToU tariff.

Can I also pocket the 10/pint reduction in alcohol tax that our Chancellor gave us.

Only if you have excess moisture to remove.

Welcome. I get a bit wheezy in the summer. High Voltage Alternating Current.

Been off work this week (well almost) so thought I would have a look at how much the nations electrical generation has changed. So some of my famous charts are coming up. Basically I downloaded the generation data, created half hour averages (means), then looked at the frequency of delivery to the national grid (the demand). I picked 3 years, 2012, 2018 and 2023 to save the charts getting too busy. I then did a second batch looking at the usage between midnight and up to 8AM. I find it interesting how usage has changed and how the distribution is getting smoother. First chart is all hours of the day. Second is the 'E7' window.

I would like to see some data on how well airtightness stands up are several years. Only got to see how much a house can shake when a hoolie hits to know that they are not as rigid as some people think.

Cut down on that is the cheapest. It is kW, not kw. It does make a difference.

Yes, it is the problem I have. I think my daily standing charge is about 75p/day, so close to £300/year before any usage. Taking the 30th November 2024, as I have the numbers to hand, I heated all my water for the day for 62p, supper time was 52p, the rest of the day was £1.37, total was £2.53. So about £1.80 for actual usage (8.4 kWh). I could, and can, reduce that a bit more, but I would then be heading into the realms of personal sacrifice i.e. a shower instead of a bath, but I like a morning wallow, could cook more efficiently and just microwave the left overs, and let the mean house temperature drop a bit more, from about 21°C to 19°C. But at under £3/day for winter usage, I am not going to change. Just makes adding heat pumps and PV not worth it for me. If I had a bigger house, mine is tiny at 48m2 TFA, with a better orientated roof, then maybe, but as I want to move one day soon (been saying that for 18 years), I am not spending any money on the place.

Start looking for a new team. If the company you are using is limited, check them, and the directors, out on the companies house website.

When you say 'pay cash', do you mean give him notes with no receipt in return?

Is that match the resistance to the PV output, which will vary with light levels. The other problem is switching DC.

Tell the neighbours, via a third party, that no action is being taken.

Cover it in fake grass. There is more than 0.3m variation in people's height. Should that mean only pigmies like myself should be allowed in the garden.

If you let go of your tinkle, your bladder will act the same.

Yes, but which model. The Davis Vantage is the best. (I got a Met Office Weather Station not that far from me, the ionising radiation collector is impressive. https://www.davisinstruments.com/pages/vantage-pro2

Yes, propane, can't remember if GSHP or no. Think it was a lockdown propject The site search facility really is worse that useless. Got google search the blogs at the moment.

Not thought of the mechanics of it much. Still trying to find who it was that made their own.

My laptop is running a bit slow, maybe I can warm it up with my mug of tea. The heat is in the thermal envelope, so no needs. Energy can be extracted out via the ventilation.

You could easily make an A2A one from a fridge. Just constantly pump some air into it (two holes in door, some pipe and a fan) and blow some air over the coils at the back.

Someone on here made a heat pump from an old freezer and a bottle of gas. Was a good write up, but I cannot remember who it was.

Get @ToughButterCup to do it, he can get to 4, then he has to expose some toes. Thankfully down here, we all have webbed fingers and toes, makes counting a quantum problem.

Usually, PV systems have a generation meter installed. You could make one of my energy monitors and attach it, then you will see what is happening every Wh, and when it occurs. And you get loads of data to play with. I have also made a simple solar intensity meter, but it needs more polishing (as I have no idea how to reliably move and store data from an ESP to a RPi across a wireless network). Then you will have even more data. Worth correlating it with your overall energy usage and the local temperatures. RH is useful to, but then you also need air pressure to get a truer reading.

Because of this thread, and never really having understood asymmetrical encryption, I have reread up on it. I think I understand it a bit more than I did. I still have not found a decent worked example i.e. the mathematical base of it.
