Jeremy Vine, was just so fine Fished every day with his line He spun it along, while all hope was gone But claimed that the fish were mine

100 kWh.m-2.a-1

Yes they are. 30 quid each for some DHT11s

Does it make it taste better when sold in an imperial unit? It is my sovereign right to use 3.412142 Btu/h (aprox) instead of 1W. Can't see any confusion. So that means I can have a short ton of of ice made in a mere 24 hours.

Cast acrylic is alright, extruded is the ne that gives problems. You can also get flexible acrylic. By twin walled polycarbonate is probably the easy one, though it does degrade fairly quickly when exposed to UV. Why acrylic is used on sunbeds it does not degrade.

I am not so keen of the remote disconnection facility. I also don't know if I will be able to use my data logger with a new one.

That is how I fixed it when it got stuck, wish I could get it to stick in the night position, any idea if that can happen?

I do. Weigh the amount of timber you put in, and every 15 minutes, note the rise in air temperature. Work out the mass of air in the room, then calculate. And while you are at it, count the number of 'rings' on each log, work out the mean, and compare the number of years it takes to grow, compared to the number of minutes it takes to burn.

I have done a quick power frequency analysis, my water heating and space heating accounts for around 9% of my total load, just water heartng is 6%, so that leaves 3% for space heating. 87% of my total usage is 600W or under. So if I divide my 4.122 MWh/Year by 48m2, my heating load is will be 3% of that, or 2.6 kWh.m-2.y-1 Suck on that. (actually I live in a very mild part of the UK, some years I have never put the heating on, and there are incidental gains to be had, which are amplified by having a small volume, I probably heat the place up a degree or two)

Do you accept that ASHP (actually all heat pumps) need to be 'plumbed' differently that a gas combi? If you do, then it is just a case of designing both systems, costing them out, and seeing which comes out on top.

And it is getting us in a right muddle. But people believe what they want to believe. Trouble is, it is very dangerous and costly. Just today, this was on. Stick with it, shows how easily 'experts' can be fooled, and fools are always fools. https://www.bbc.co.uk/programmes/m000q3d5

Yes, as the volume increase, the volume to surface area decreases, so large houses use less energy when measured by square metre. This is party because fixed loads are similar i.e. cooking, refrigeration, bathing. One of the reasons mine seems to high, but my total usage is pretty reasonable.

I have an energy monitor on @joe90's meter. Not sure where the data is as I have backed it all up, but did upload it once, so may check Drive/Onedrive and see if it is still there.

For a shower, a quarter of a tonne. You are not in Cornwall, that would cost you £2.

Luxury When I was a lad, we had ice baths, with grit instead of soap.

There must be a Limerick there.

What I wanted to know, at the time, well, just before I looked at it, is why is the medical version so much thicker than the eBay version, sure the thinner it is, the easier to clean. And why do they need to bend it though 90° once it is inside, surely a mirror would be easier.

Still, could be worse, just imagine if a Physiatrist joined, there would be special pill deliverers to Wales. Like Screaming Lord Such said when they got more votes than the Liberals "We could do with a good Doctor". And I am sure we can get some high quality borescopes.

Oh good, Physics. https://www.independent.co.uk/news/science/stephen-hawking-black-hole-hairs-information-problem-a6819986.html

Right, I have spent 30 seconds doing what anyone can do. Got this: https://medium.com/@simon.aubury/home-power-monitoring-65d0fded7769 I am sure with a bit of extra coding, it can sense when the main meter LED is permanently on i.e. exporting. Then it can either start logging the generation meter pulses, or again, with some extra coding split the data up into times when it is purely imports, purely exports and a mixture of the two. All nicely timestamped and in an easy to read format. It would also be easy enough to put an indicator on it as well, or a switch or 10.

There are evaporation losses to consider, these can be quite substantial. https://dengarden.com/swimming-pools/Determine-Evaporation-Rate-for-Swimming-Pool

Shipping Forecast is on then, everyone should be up. https://www.metoffice.gov.uk/weather/specialist-forecasts/coast-and-sea/shipping-forecast None of us will be surprised with that, they may well know that you keep turning it off, some of these units have loggers in them and they will know what is going on.

You are not sleeping anyway, and I think, if you do get your house up to temperature, it may well not have to run during the night. There is no way you can not try this in reality. If I was the installer, I would just claim that you were turning it off all the time and making a fuss about nothing, then charge you £10k to remove it. It is a bit like trying to drive a car up a hill, a car where you refuse to use the brakes at all, but after you have moved 50 metres, you just let it roll back. Then claim it is the car/hill/life that is faulty.

I shall get back to this, got some sunshine so outside at the moment.

Yes do
