The floor temperature will be pretty close to the mean flow temperature, so no real need for extra sensors. Extra sensors would be good for data collection and analysis, but not many people are as nerdy about that as me.

Yes, and it never helped the fisherman.

It is all going to be fine, the Cornish have come to the rescue. https://www.bbc.co.uk/news/articles/cewzg77k721o All I will say is that we have been here before. https://www.cornwallislesofscillygrowthprogramme.org.uk/hot-opportunity-european-investment/

That is the hard bit. That is because I was being a bit flash to work around the charting limits in LibreOffice. I would recommend downloading the portable version as it does not install itself on a PC, just runs from a memory stick. I have some data about ground temperatures that I am looking at, so may be able to make some sense from it.

Was about 2 hours, over a coffee, but 45 years of studying.

Use an adhesive. You could do a couple of tests and see how it 'feels'.

Not as much trouble as when you find out it will only increase your energy usage.

Well at 0.1, 0.2, 0.3 and 0.5m depths, which is about the normal depths for foundations. There are many things that will affect the temperature at different depths, hours of sunlight and rainfall are probably the biggest factors. I think that data is available from the RU website. Wish I had more time to look at it all.

I just happen to be looking at some ground temperature data. I am not so sure it is a good idea to bury air pipes in the ground, even at 1m depth, it is only from mid March to September that the ground is cooler than the air, and then only by a maximum of 2°C. At the half metre it is about 1.5°C cooler. I also suspect that the energy transfer efficiency is not too good.

As this is temporary, could you not cut some plywood up that is deeper than the current beams/joists/rafter (not really sure of the correct terminology) and sister then up to the existing beams/joists/rafter. With correct trimming at the ends, they could bear onto the top of the wall. They could be cut to make the beams/joists/rafter either deeper or taller. Something like this. Or better still, if you are boarding, the other way around, so the original timbers are at the top.

@Gus Potter @SimonD I use Libreoffice Portable https://portableapps.com/apps/office/libreoffice_portable Can take it anywhere with me. The problem may be that I used REGEX() to split up the array's columns and rows headings, not sure if Excel supports REGEX() (it should as it is a normal function in the IT world). I did think of one problem and that is when using MVHR, the result should be added to the ACH result as it is, in effect, and extra 'leak'. This part was not a great deal of work. I may try and make one that separates the 'ground' face of the cuboid and adds in some percentage of window area.

@Gus Potter Seem to remember that JohnMo had a similar problem, must be Scotch Software. This, it is saved as an .xlsx file. Compare U-Values and ACH.xlsx

Been a bit bored as I have not been able to concentrate on anything much recently, but life is getting back to normal. I read on here a lot about the advantages of insulation, airtightness, MVHR etc, but this misses a few points. Form is one of them, a simple cube is a pretty good shape for thermal efficiency, and the bigger it is, the better it looks. So I thought I would knock up a very basic spreadsheet that can be used to explore the differences between size, form, thermal properties (just U-Value), air changes an hour for a cuboid. This is basically to just show the ratios and theoretical power transfers. Cells B3 to B11 can be changed with the snapshot results shown in cells B13 to B17. Below that are some data arrays that show ventilation and fabric losses, and ratios for surface area to volume and fabric to ventillation for different form factors for the cuboids. Not sure how useful this will be to anyone, but it does put numbers to changes i.e. you can change the ACH and U-Value and see which will have the greater effect. This is a very limited scope spreadsheet, so a lot of interpretation is needed. It does produce some charts though. Compare U-Values and ACH.ods

And very relaxed you will be as well if you put it next to the Bob Marley tree. Personally I just want some of this.

Try putting a cheap phone up as high as possible and see what happens. Or you could play about with an old satellite dish and see if you can get a stronger signal. When I was at the college, I managed to get onto the university network that way, and I was about a third of a mile away.

Replace with for for.

Or a U-Value of 0.35 W.m-2.K-1. U = 1 /R. Half the BR's wall regulations. Mineral/Rock wools, at 135mm thickness is 0.3 W.m-2.K-1 (at a k-value of 0.04 W.m-1.K-1. So not really sure what to make of that claim, other than they have somehow factored in ventillation losses.

There is a 5G mast 200 metres from my house. I must go down to Goonhilly and Poldhu, the spiritual home of radio, and see if there is still no signal.

Never tried one, but two things. Are the legal, seem to remember than some are not. Do they do a 5G version, 4G is to 2010s.

The new member was @jon-lee, but not posted in a while, think he was scared off by a mod. Shame.

Concrete is a fascinating subject. We had a new member joining a few months back that was involved in it, can't remember who now, think he was from the South East.

A legend in a loincloth.

Was an Alan Davis program about what would happen if all the rats vanished. Our lives would be worse. https://www.bbc.co.uk/sounds/play/m002rf05 Now this is how I deal with fat and waste. First we collect the food. Any fat, liquid or solid is kept here. Locked away for insurance purposes. This machine does a bad job of getting the crud off. With all the waste water going down this hole to the grease trap. It has been a slow day today so I have been hiding from workmates. They think I am writing a report about the drains.

Why would it if they were the same energy storage and similar power delivery. Workmate of mine did the same. Found out the problem is the way she used them i.e. turns the fan in when she gets home and leaves it on.
