So that is the chlamydia sorted, how is the COVID-19

Shelia in town You sick bastard, she had only just left mine.

It's a date once I'm better! Maybe we could go onto Thorpe Park afterwards? Or Windsor to join the Queen for tea, Andy may be there to amuse @pocster

@Onoff Just a word of caution. COVID-19 can take a strange path in people. A day of two of roughness, then a day feeling better, then, and this is the bad part, you can deteriorate rapidly. Take it steady.

Seems a good reason to have a dumb meter, except it cannot log the time you export. But a bit of trickery with ToD and FiTs could pay dividends. I feel that all these ToD tariffs are going to vanish for the consumer. The large companies will develope systems that integrate seeminglessly into the grid and we will not have to worry about it. Will work out cheaper as well because they will fit it where it is needed for local grid reinforcement. It is cheaper to fit a MWh of grid integrated storage in one place than 100 10 kWh distributed system

Don't leave a hole in the ground too long, or deep, @pocster will come and try to build a house in it. Glad you don't feel too rough with the covids.

Possibly. I was in a meeting at the time. You will get 40% of the chemical energy as electrical energy.

PFP Energy went last week.

Both of you need a statistics lesson. Each spin is a new game and previous losses are no indication of the future At least it shows it is random (though not truly random, not many things are). Would be a better game if you could bank not playing and the odds of winning increased each time i.e take away the high or low winning options.

How much is it, then divide by 10.35 [kWh/litre]. Then multiply by 0.4 if you get a proper generator, or 0.25 if it is an old car engine. You could scavenge some thermal energy as well, maybe 0.1 of the maximum daily input. Kerosene will go up rapidly when air flights increase. There may be storage life in aviation fuel and it is being dumped on the open market.

https://www.current-news.co.uk/news/octopus-energy-sees-160-jump-in-revenue-but-still-records-loss-due-to-relentless-investment No sign of over expansion and ambition is there. And the Kraken Technologies seems to be a cloud database with basic AI (which is anything but intelligent at the moment).

What sort of disc or cutting wheel was on this low powered angle grinder, and was the guard fitted, and to what proportion of the disc was fully exposed to finger inadvertantly touching it, @ToughButterCup has a statistically lower risk advantage here with 2 fingers missing. or just take the (expletive deleted)ing batteries out and put them in a charger.

Or live in the far west, as I do.

Some RH sensors are capacitance based. Some switches are also capacitance based. Touching a terminal may just have changed the threshold enough to trigger the switch.

It is the place that organises all the generation data. @DamonHD is the main expert on it here. https://www.elexon.co.uk/knowledgebase/where-can-i-find-details-of-wholesale-prices-of-electricity-in-great-britain/ https://www.bmreports.com/bmrs/?q=eds/main

Those numbers seem insane. Is there anything on the ELEXON portal to show this as a general trend, or has Octopus over promised and under bought.

Probably not. This is a building control issue, not a planning one.

That is because your house is modern, and almost airtight. In an old Victorian place, both the above are missing. A secondary ASHP may need to add an extra 6 kW for 50 or 60 days a year, then occasionally an extra 8 kW. Too large a HP will short cycle horribly in the non heating season and be almost large enough to run an instantaneous shower. I am going these calculations in my head, and I am just off to work again, but I think having just one size ASHP, even allowing for modulation, is too high a risk.

It is your project, not the architects.

130 kWh / 4 h = 32.5 kW That would be a silly size. So maybe two ASHPs, one that does the space heating most of the time, so something like a 12 kW model into a thermal store/large buffer. And a secondary one for DHW and those odd days where air temperatures are lower than expected, say a 5 kW one. You are not going to get a cheap system that can run for only 4 hours and supply everything on the worse day. But we don't have many days like that, so why design the system for those extremes. And what do you do when Octopus pull the 4 hours cheap rate?

According to @pocster, everyone in Cornwall starts with 12 fingers and toes, it is only the webbing that masks the extra ones.

Dig a deep hole and bury your first attempt of building a house in it. Then build a new one on top.

An architect will work to minimum building regulations, while charging extra because they are 'the professional'. You really need to do a thermal model. Now as you like woodworking, have you considered a stick build?

10 quid fan heaters, it will not be long until the carbon content of our electricity supply will be 50g?kWh which will beat combustion technologies hands down every day. This is not how you set up a heat pump system. 130 kWh / 24 h is a power of 5.4 kW, which is ASHP terms is about as small as you can get.

The Building Regulations are here: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/697629/L1B_secure-1.pdf The L1B is for existing buildings. Seems to be 0.22W.m-2.K-1 unless it is an upgrade and then it is 0.25 While you may not have to improve the losses though the floor, you may want to. Part of thermal calculations is temperature difference, and as the ground does not change temperature much, and UFH heats the floor more than an unheated floor, it makes sense to insulate it more.
