Steca used to do a system 2kW system that you can add extra 2 kW slave units to. And they kicked in at a low voltage, 80V I think. You may be able to do things with micro inverters as well.

Can raise the roof with one of those.

Probably. Still, make for a good woodstore, only sustainable carbon dioxide to kill you.

Why I am asking the question. Seem to remember that too many people have died from gas poisoning in them. Seems they are, but surrounded with more rules than safety guards. https://inspectionpits.co.uk/hs-guidelines-for-inspection-pits/

What are you measuring mass flow rate against? A dial position, a linear scale, a numerical display, or the power to run the fan? I think the power is the cube root of the mass flow rate.

Are they still allowed?

I thought we voted to leave Europe because we think everyone else is inferior.

Stop calling it a garage. Research Facility sounds better.

Problem is solved now, it is cloudy and 15.5°C outside. Feels like an autumn day.

As there is not going to be a building on top of it when you poor, if it does not get the finish to want, you can always grind/polish it after. Are you going to put some UFH pipes in, then you can collect some solar thermal from the roof and have a heated motor house.

I had one once, 1750HL. Was dreadful. Harsh suspension that somehow stopped the wheels gripping the road, accompanied with lots of banging and body shake. The steering got heavier and heavier the more you turned the wheel. The engine used almost as much oil as it did gasoline. It had a 5 speed gearbox, quite a novelty back then, but all of them were hard and heavy to select, no fast and slick changes, ever. And as this was a top of the range model, I wanted more than an MW or LW radio. The seat fabric was that velour, in brown.

So true, if only I could buy an Austin Allegro.

The reason I say that the problem is the wall, not the window(on the west side in the photo) is that there is a lot of area, the window is quite small. At this time of year, even west facing glazing is reflecting a lot of light as the sun is still quite high in the sky, we have also had high temperatures and lots of sunshine for 3 weeks now. I have picked Dorchester as an example. The solar is measured in the horizontal plain, so only noon is close to correct, either side of that, more power from the sun will be hitting the walls (if I feel up to it I shall look at the solar angles and do a bit of trigonometry, but I have a busy day tomorrow, maybe others can do it) Assuming your west facing wall starts to get a decent amount of light on it from 1 PM, then since the beginning of the month, there has been a mean of 375 W.m-2 hitting it, peaking mean is 579 W.m-2. The mean afternoon temperature, when the sun is out, has been 21°C. The night temperature has been 14.8°C, the morning till 1 PM temperature has been 16.7°C. The daily mean of the period has been 17.8°C. To see how things changed over the month, here are some more charts, but week based. Week 22 is the first week of June. Week 23 Week 24 (gone off the scale a bit) Week 25

The roof limits how much PV you can get on it.

I was a bit short of cash a while back and my partner was desperate to help. I suggested that going on the game would be an easy way to quickly get some cash. Reluctantly they agreed, came home after the first evenings work with £100.50. I asked who handed over the 50p. "Everyone"

Can you use a wobbly bar, inside a tube, attached to a drill, to vibrate the air out.

The physics days it should shield the wall from direct light, and as leaves absorb the red and blue light, they should heat up. As they are mostly water, quite a lot of energy is absorbed. But then, depending on the plant type C3 or C4, they transpire, mostly water vapour and a little oxygen, and a lot of nitrogen, so that shifts the energy balance somewhat. Also, plants are piss poor at converting sunlight into biomass, generally 0.25%. which leaves a lot of energy just passing though, one way or another. I am not sure how easy it is to calibrate for different emissivity, probably very complicated and needs special kit, though there may be general numbers that are good enough.

Is the idea of a bull float to barrow the concrete mix in, then, stand at one end, and push and pull the float over the mix? If so, how important is the mix? Are there mixes that are better than others i.e. additives?

Feel I am going backwards. Was in my 40s then, now late 20s.

I did an experiment where I grew some grass in a tray and compared the temperatures to a similar tray with just dirt in it. No real difference I seem to remember. https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7304&page=1 There is a lot of talk in the 'eco' world about it, but little evidence to back it up. I do like the look of it though, walls are a good size canvas and need to be decorated. I have a lizard and a butterfly on mine. Edit Just reread what I wrote 12 years ago. Seems I compared a roof tile and grass, with the soil making the difference, not the grass.

That is quite a lot of surface area to get hit by the afternoon sun. You could try a some solar reflecting paint. https://www.rawlinspaints.com/home/roof-paints/solar-reflective-paints/551-coo-var-solar-reflective-paint-white.html Putting a hand on a window is really showing how powerful the sun is. I still have my winter secondary glazing in place, so in effect, triple glazed windows. I am not sure if it is helping or hindering. Hindering I think, but that may be because I can only open two windows now, one upstairs and one downstairs. Leaving it as it is as I am collecting data and can do some analysis later. When we had the heat warning last year (first time it had happened in Cornwall) I found a just closing the curtains made no difference. The year before 2021, when in my location it was even hotter, I tin foiled the windows, that made a 10°C difference. So maybe cover the top half of the windows in tin foil to reflect the excess solar energy. But I think your problem is the wall.

Is the east or west wall the end. By the time the sun is on a west wall, the OAT is pretty high. My house temperatures have be high this last week, even with the OAT temperature dropping to 15°C last night, the house was 23°C this morning. I have a jumper on at the moment.

Will need a lot more data. Which wall is becoming a 'storage heater' assuming that the south facing wall is mostly windows and doors i.e. front of the house. What sort of areas? How does the internal temperature correlate with the outside temperature? How is the roof orientated and how well insulated?

Yes, it is a problem now. Mind you, not all Chinese made stuff is bad, they have very good engineers there.
