    That would have been because they were too small for the property. I limit the charge period of mine to 4 hours. Works well. But that is because they are sized correctly for the house and climate.

    When I am at work. I am still worried about these 'challenger' companies. How can they do it so cheap compared to the big boys.

    Shows how useful network cable is. One can be used as a washing line. Probably the biggest energy saving device available.

    Not bothered to look at the Notts site for years, but does the 20p/kWh include meter rental and taxes? Or a blend of day and night rate (which is tricky as you need a split). It may also reflect standard rates, rather than one off introductory offers. It is really quite easy to go to Google and find out what prices are being charged by the big 5.

    Can you get hold of decent weather data in Slovenia? Our Met Office is pretty good, but there is a large amateur network, WeatherUnderground, that has thousands of weather stations in most countries. Always worth a look to see what is near to you. The calculations of heat loss are fairly basic. This site is a mine of knowledge: https://www.engineeringtoolbox.com/heat-loss-buildings-d_113.html

    See if you can read the other meter. If the numbers are similar, then get it sorted. If the numbers are in your favour, get it sorted. Think you know what is coming next, if they are not in your favour, keep quiet.

    Do you know the thermal properties for each component that is exposed to the outside? Then it is a case of hunting around on here to find @Jeremy Harris's heat loss spreadsheet, punting in the numbers and seeing what comes out.

    Yes, why I was wondering what the max is they deliver.
  9. SteamyTea
    Ah, I thought it was the maximum from a wall socket. So what is the maximum it can deliver, 10A?
  10. SteamyTea
    Is that for any EV, or just yours? I can understand limiting the load when charging from a regular socket, but 6A is a bit low.

    There was a bit on Radio 4's You and Yours about someone paying £400 a month to run a couple of 'electric heaters'. That is around 2 MWh. Or around 2.8 kW. No idea how large the place was, or how much she is actually paying for electricity, just that it had leaky windows. Was about the new fines coming in for landlords who rent out G and F places.

    I suspect that Yorkshires moved here as economic migrants in the 18th and 19th century, then took what they learned back, including Trevithick's boiler designs.

    And a Cornishman is a Yorkshireman with the last drop sucked out. I got my car MOTed and a mate, instead of asking if it passed, said 'how much did that cost?' Now I just put silly numbers on things to upset him.

    Are you using MicroPython on them. @TerryE knows a lot about them but he uses a different language, and I don't really want to learn too much as I struggle with programming. As soon as I see a {} I get nervous.

    Buildhub should set up a calibration service. I always wanted to work in the calibration office where I did my apprenticeship. It was cleaner and quieter than the toolroom, and women worked in it (I worked for an American company and there was not one female engineer in the whole place, seems odd looking back at it now).
  16. SteamyTea
    Buy one, then I can calibrate the cheap ones I have bought. You know you want to.
  17. SteamyTea
    Just bought a couple of those cheap MH-Z19. Once the Chinese get back from holiday, get over the flu, and trade is back to normal, I may get them in the post.
  18. SteamyTea
    Is it possible to suck the CO2 out of the air for calibration purposes by adding something like calcium carbonate (in a container), or maybe just reducing it to a known level by heating up some distilled water and letting that absorb some. Or maybe just 'burping' a jamjar with nitrogen. RH sensors can be calibrated in a similar way with a salt, or copper sulphate solution, just wondering if something similar is possible.
  19. SteamyTea
    Right, thought the VA had a built in sensor. I am internally debating about getting one of those cheap sensors. Just to add to all the other ones I have. Need two really, one inside and one outside.
  20. SteamyTea
    Be fun to see the readings when there is a bonfire nearby. So how come the VentAxia is showing 1000 ppmv and the other sensor was showing 3000 ppmv? Was it before mechanical ventilation?

    Not in NI at the moment. https://www.belfasttelegraph.co.uk/news/northern-ireland/mot-tests-for-cars-and-light-vehicles-in-northern-ireland-suspended-38901362.html

    If it is a proper 88 kBTU, then that is 26 kWh. Or just over a constant 1 kW (1.08 kW). 26 kWh / 24 h Get your heating people to give the answers in SI rather than Imperial. (You may find there is a few of us that seem a bit nitpicky about the whole kW and kWh thing, the idea is to save confusion in the long run. We also like to work in SI units as these are established and agreed upon)

    Used to make log saunas, they sold for about £1500/m2, 30 years ago.
  25. SteamyTea
    Yes, it was posted before I had finished my first mug of tea.
