The great north south devide
SteamyTea replied to nod's topic in General Self Build & DIY Discussion
I am currently on a parallel that is equal to Bordeaux, and they pretend to speak French here. I think I am the only one that has been to France. Where I usually live, you are all Northerners! -

Just done a quick and dirty analysis of house sales in Harrogate, Oxford and Poole, they are next to each other in population ranking (i.e. size of borough). Make your own minds up if Harrogate is a 'southern' town. -

Name a comparable town to Harrogate in the South and we can compare the two. -

Always worth looking at the whole picture, rather than just an obscure quirk in the market. http://landregistry.data.gov.uk/app/ppd/ -
Yes I think this is a topic for another thread.

Not if you are one the cheapest duel fuel deal https://www.ukpower.co.uk/regional_energy_prices But shows that there really is little benefit in shopping around unless you are on a dreadful deal.

Was there not a story about a guy from Culdrose that got in trouble for having some WD40 in the boot of his car without the proper chit.

Too much sugar for my tea

How can you tell if it has asbestos in it. For some reason they decided to cover my house ceilings in it, no idea why. 1987 vintage.

Insulation, Heating, time constants etc. Am I expecting too much?

And that really annoying thing that happens every now and again has happened. No matter what I do with the formatting, it stays as strike though. -

If my memory is working right, thermal inertia is m2.K-1.s-1 for a given thickness of material i.e. your walls. So say you have 100m2 of wall and you have heated it up by 10°C in 24 hours, that is: 100 [m2] /(10 [°C] x 86400 ) 100 / 86400 0.000166 m2.K-1.s-1 Now if your wall is 200 mm thick, then 0.000166 / 0.2 0.0005787 m2.K-1.s-1 The reciprocal of this is 0.48 h.K-1, so about half an hour to raise the temp up by 1°C I have made some assumptions there as I don't know the size of the wall area, or the thickness. There is also the problem that the wall can only heat up (or cool down) once for every temperature change, it is not really like a proper battery as it only has the temperature differences to work with, not an excess of temperature. Then there is the problem of heat loss to the outside, that probably accounts for the wall being at the median temperature point of inside and outside. And I have not taken other losses, or gains, into account. -

I am sitting in my Aunt's kitchen, which is almost identical to my Mother's kitchen, except it is in a different country, on a different continent and separated by a decade at least (Aunt's is older). How odd is that. Both kitchens are almost the size of my house.

As long as I can make it do this:

Yes please. I am sure Build Hub could cobble something together with a Pi Zero and a 1-wire sensor

That is the way to do it, set achievable targets and get on with them A good rumour is halfway around the world before the truth has its pants on!

Be interesting to set one up that senses interior temperature as well. If it is a simple control system it could work well for roof lights.

I am keeping my mouth shut except to mention that the contingency is 17% for each element. To my mind that is just a fixed costing and is not based in reality or experience. Try getting away with that in a restaurant because the chef is useless and see how long your last.
