Not sure what to make of that.

Probably twist the picture frame.

A hinged bucket on wheels then. Now, I lived in France and was joined by my Belgium cousin for a few days. He was always amazed how well I got on with the local girls and wanted to know my secret. I said it was simple, I just put a potato down my Speedos. The next day, he came up to me and said that he had been trying the potato trick but he was just laughed at. I said 'You need to put the potato in the front of your Speedos'.

There is another way to look at efficiency, and that is comparing the surface areas of the emitter and the receiver. This is something that bugs me about radiative heating. If the object to be heated has an exposed area of 1m2, and the emitter covers 10m2, then that is a simple 10% conversion, with 90% not heating the object. This ratio cannot be reduced by increasing the temperature of the emitter, or reducing the distance between the emitter and the receiver. That just changes the temperatures reached. Also, when keeping people warm, the claim that the local air temperature is unimportant just seems odd to me. As we breath in and out, we move air about. If we breath in cold air, we have to heat that up, using energy. As we breath out, that warm air is expelled, loosing some of the energy that we have used in heating it. There is also the enthrapy losses from the change in humidity. It is much easier, cheaper and more efficient to just heat the air that we live in.

Took me ages to find out the difference between an oral and anal thermometer. It is the taste! Jeremy is going to post up something really serious and sciency about efficiencies soon, hope I have not put people off.

Tougher in fact.

Welcome Mark Without seeing the pictures, and if you don't want to change the doors/thresholds, can you get some ramps made up to make entry and exit easier.

My Father chopped some toes off with his petrol Flymo. Just for clarity, if you chop your big toe off, you only temporarily loose your balance.

Joe90 lives in Devon, they do odd things there with pasties and cream teas.

Just pulling up your data now. Here it is, big loads first, then the little ones.

Pick you up too, you will need to keep that garage warm when working all winter on your car and tractor.

Chop Chop then as I am interested in seeing the data, methods used to analysis it and the conclusions drawn. Where is your factory, if it is local to me I may drop in. Just seen you are in Andover, about time I did a trip up country, can pick up @JSHarrison the way.

My major loads are at night, but if I look at the fraction of time that I am drawing up to 10W, it is, between 28/06/2019 and 07/07/2019 (last week) 0.6, so 60% of the time. 10W up to 20W is 0.01, 1% of the time. So that is basically the radio, laptop and fridge, toilet MVHR unit. If I look at the same time period, but bin the data into 1kW chunks, then 0W up to 1000W is 0.92, 92% of the time. 1000W up to 2000W is 0.004, so less than 0.5% 2000W to 3000W is 0.05, so 5% (probably kettle and cooking and maybe washing machine) 3000W plus is 0.021, so water heating is around 2% of the time. I need to work on my sub 1000W loads, but mainly below 50W as that accounts for 72% of the time. Radio is 3W, laptop 8W, fridge, on average 5W. But when I look at the numbers at 1W resolution, 60% is between 0 and up to 1W. So I am not going to worry. 60% of the time I use no power at all, I should ask for a reduced meter rental.

Plenty of radon down here, one of natures own nuclear reactor.

Few metres lower, I am always surprised how high I am, probably accounts for the wind and rain.

So 2.55°C different for 200 km West, similar altitude I think (you may be a bit higher), but 25 miles from coast.

For a laugh I have just looked at my external temperature, it is 21.75°C at 11/07/2019 13:47:24 What are other people reading for a similar time?

If we just put PV on our roofs, that would reduce the energy getting though by about 20%. We could also put reflective film on windows, probably cut out 30%. Flooding is probably a bigger risk than drought, but personally I can't see London getting the same climate, or even the same weather as Barcelona. London is in a plain, Barcelona is coastal, but the Med, which is a unique sea. Barcelona is also surrounded by hills. Worth remembering that Barcelona had a lot of infrastructure changes brought about by the Olympics, London did not.

And set up a radio station. The pictures are better on radio.

Mining area here, so all badly polluted, leaks radon, agriculturally worthless (good land is Grade 3b). Or something like this: USS West Mahomet in First World War dazzle camouflage

They didn't collapse then, and they would be bailled out again. I have often wondered if you found a bit of common land, put some plastic pipes in it, cordoned it off with spikes and hi-viz tape, then put some signs up saying: "Contamination Survey: Do not remove" Then, if it does not get disturbed for a year, put a large box filled with concrete on it. Then a shed, then a few piles. Then a bigger shed, but with windows. You get the picture.

Welcome I would spend some time properly learning all you can about building physics and planning law. If you really want to make a difference, get on the local parish council and work your way up the political ladder. There is a serious lack of 'young' people involved in local politics. Failing that, how about a houseboat.

Would you really want that actuator cluttering up the view.

My argument was not to do with the emitter area or temperature, it was to do with the albedo, temperature, area, line of sight and distance of the object receiving the IR.

It is selling the infra red dream again. Work well until you put some clothes on. I really thought this nonsense had been banished, but seems that people think there is a real advantage to it still.
