At least the problem is now officially recognised, even if the solution is way off the mark. https://www.airqualitynews.com/2018/05/22/defra-launches-clean-air-strategy/

I only visit Devon when the weather is dry

We used to use Vapac units as steam generators. They were designed as HVAC humidification units. You may be able to find something, like a wall paper steamer, that can do the same thing. Just stick the pipe in the ducts to the rooms, simple RH controlled switch, and job done. I am not sure where you are in the UK, but my external RH has been pretty low, down to 62% on the 19/05/2018, by the time that has warmed up in the house it is probably down to 45%. Edit: Just looked at yesterdays RH numbers at between 2 and 3 PM, RH was at 50%. No wonder I feel so good.

When my Father was a site engineer in the 1950's, high temperature pipework was insulated with a wet asbestos mix, applied by hand. There were 4 British engineers working on the project, 3 died of asbestosis before they were 70. My Father was the one that did not. This was out in the Far East and the majority of the labour force was Indian or Chinese. As far as I know, even back then, there was concerns about asbestos. In 1977 Iwent for an apprenticeship at a company called Railko who made bearings. They were using asbestos then and part of my duties would have been to monitor the air quality. When I mentioned this to my parents (as I was quite keen on the job), they said 'No Way'.

If you take away mass, which is just the stuff something is made from, energy is transferred by radiation only. So it depends what colour and finish the outside of your roof is. Shiny silver, don't worry, matt black, worry. I think a pure vacuum's decrement delay is only limited by the speed of light. So no. But that is before virtual particles comes into play.

Because a vacuum has no mass. Not strictly true in the case of a vacuum panel, but they are of such low mass and low SHC (the kJ/kg.K or kJ/m3.K) that they can be treated as zero mass. They insulate by stopping conduction, which is usually the dominant transfer of power (the W/m.K). (this is often known as a 2 1/2 D problem)

Here is the digger I use. If it is good enough for Charlie Dimmock to get pleasure from, then I am happy to hold it afterwards, while imagining her 25 years ago. http://www.poundland.co.uk/charlie-dimmock-wooden-handled-trowel

I often wonder how much 'illness' is just caused by misdiagnosing the symptoms, coupled with the health profession's arrogance that they are always right. Also it is far to easy to spot a pattern, where no pattern exists, from a small sample of cases. This is not a new problem, "Three Men in a Boat" was about ill health.

All you need is a bit of unwanted UFH pipe, a pump maybe and a valve or two. You could stick the pipe in a bucket full of anti-free (or salty water) as that may control the temperature a bi better. Let us all know if you give it a go.

Murderer This is my old GP https://www.independent.co.uk/news/voices-in-doctors-head-told-him-to-kill-daughter-1574679.html

One of the problems of that class of drug is that it is not affective in all people. Estimates of effectiveness range between 0 and 70%. This is a case of very bad medical practice. "If you drink and smoke less than our Doctor, you will be fine". when having my lifestyle criticised by my GP, I offered to race him to the roundabout and back, he declined (my local GP surgery was put into special measures, and they wonder why the health of people in Cornwall is so bad, we have a dreadful NHS down here compared to most parts of the UK).

Most of that was done by reducing infant mortality and vaccination against killer, or life shortening, diseases. At the top end, improved working conditions, better home comforts and labour saving devices have played dividend. Also we have not had a major war that wipes out 3 million fit young men (7.5% of the population). Or Spanish Flu, that killed more people world wide than the Great War (though may not have killed more British, though it did tend to hit people in midlife worse than the two extremes). So like expectants, and the associated 'health' of the nation, seems to be unaffected by diet or self building. Edit Spanish Flu killed 228,000 of the UK population (0.5%).

How about an old freezer. Put a water coil in it, plumb it into your UF pipework, and when it is hot, turn thee freezer on and divert the heating water via the coil in the freezer (put the freezer outside in thee shade).

I often wonder if freshwater fish has the same affect. Not putting i to the test to find out, but you can try it and report back. I always though that a tingling on the tongue and roof of the mouth was normal. I had an stomach infection, Helicobacter Pylori, for 40+ years, nearly all my life. So I always thought that indigestion was just normal. Was not until my Father got treated for it and we were chatting about the symptoms that I realised that I may well have it. My Father was one of those people that had a good long term memory and could place when it started. Balikpapan 1962. I was treated in 2003. So all I can say is that the two major world contributions from Australia are the rotary washing line and the cure for HP. Well done Australia.

Allergies: I am allergic to just about anything with fur. Most of my early life I was a wheezy child. Because it was the 1960's and 70's it was because I was all caused by what we now call stress. My parents always had a cat or two. Left home to go to university and my wheezing cleared up. A decade ago I started working back in catering as the hours suited me while I was studying again. As it was a fish restaurant I was eating fish 3 or 4 times a week. Fish is good for us as we all know. After a few weeks I could hardly talk, my voice was croaky and I had trouble swallowing. This was put down to me being a smoker. Stopped smoking and it did not get better. Bugger me I am allergic to fish. Rub a tiny bit on my skin and it erupts and cracks in minutes. So I am very wary of 'diets' being a cure all. The Mediterranean diet is a killer for me, almost. I like Pizza. Cleanliness: We live in a society that takes this seriously, it is very unlikely that we by goods that have anything nasty on them, food included. So an extra bit of cleaning around the house with bleach and sprays is not going to make much difference. I think obsessive cleaning is a different problem and often forced on others. I think they call it Münchhausen Syndrome by proxy. Medical Research: Just read Ben Goldacre's (who has a fantastic mother) Bad Science and other books to realise just how hopeless medical research has been (thankfully improving now).

I agree, and shall ponder it more as I drive up to Devon in a little while.

I am still thinking about this. My first thoughts are that there is a big difference in comfort levels at different RH levels when the temperature changes. I don't think that it is simply a case of trying to keep the RH fixed regardless of the temperature. The second thought I had was how will it cope when conditions are out of range i.e. high internal temperature and very high external RH (like yesterday). would the boost just be permanently on. Also, would the rate of change curves be fixed or dynamic? In the UK it really is possible to have 4 seasons in one day. I am sure it is all solvable, just a case of working out what is really wanted.

If you can't fit East or West, but have spare room on the South, then a few extra panels could generate just as much in the mornings. It is easy to be amazed by generation figures on a very sunny spring or autumn day, there are a number of reasons these can look impressive i.e sun angles, temperature. But the truth is we usually have cloudy weather, and when we do, angles become less important. Part load inverter efficiency can dominate then (though they are all pretty good these days).

"That's entropy man"

Shower circuits often take a tortuous route to the shower, often many times the shortest distance. Just a matter of cable sizing really.

As far as I know the rules about storage are the same as PV. It is to stop linesman's being shocked. And they like to know where all the isolators are. I would not be surprised that in the not too distant future the fire brigade would need to know as well. Lithium and fire do not mix well.

The main point I would like to make is 'know your usage pattern'.

Yes I am on E7 only. If I take the total cost i.e. standing charge and VAT into account then my kWh price is, on average 15p/kWh over the last 50 days. This goes down in the winter as my day time usage is pretty constant, but my night time goes up (all to cock this year as my E7 element broke, but other years show a consistent pattern 15% day usage, 85% night usage). Quite simply, if you want to store energy, do it as DHW first (200 lt cylinder with elements about £300 and will last 30 years), this can be either for direct usage or as pre-heating. A Sunamp will do the same, but at several times the cost. Then, if you have any spare electricity, stick it in a storage heater that is placed centrally in the house i.e. hallway, or somewhere that is permanently cold i.e. dark north side. Whenever I look at batteries they just don't make technical (you have to inform your DNO you got them if grid connected) or financial sense. Good fun to play with though. Realistically rather than looking at price, CO2 emissions should be the metric.

Lots of talk about what can be generated by PV, not much information about time of demand (TOD). That is the important thing here, the rest is just hardware (either what you have or can afford). TOD is behaviour. Here is mine for the last 90 days.
