My mad ex #2 graduated from throwing plates at me to throwing knives at me.  Plates I could handle, but a knife thrown while I had my back to her was too much.  I opted for a more peaceful life...

Did she swear that you reversed into the knife?

The local mafia who have been dumping bodies in oil drums are getting a little worried I'd wager.

Yeah, expect to see 'No scuba diving' signs going up very soon.

The only thing that's shocking is how easy it is that he can keep a straight face whilst feigning alarm.

I wonder how easy it will be for a Russian aircraft to obtain Boeing spare parts in Thailand?

Maybe Aeroflot can go along to Somchais Used Aero Parts in Suphanburi. They have plenty of barely used Boeing parts an Austrian gentleman donated years ago.

The falang mentality.

You mean pointing out Prayut says he'll keep the price of diesel below 30bht when it's been above that for some time?

BTW between 31 and 34.5 where I live....the locals aren't enjoying it at all.

Nonsense - the average death is OVER life expectancy. Below was from January 21 - ONS - it would be impossible for life expectancy to go down based on deaths above life expectancy !

 

Cumulative total of Weekly deaths by age band

Age Bands	Number of Deaths
<1	2
1-4	1
5-9	1
10-14	5
15-19	11
20-24	34
25-29	70

80-84	15,374

Wrong, older people dying younger than they would normally drags down the average.

Edit...edwinchester beat me to it with a simple explanation.

That could be interpreted as 50% but I know you don't mean that. It's the same...half of one-percent (written different ways).

You're wrong, 0.5% and 50% are entirely different by a factor of 100.

Should have bought some helicopter gunships rather than submarines.

Hi, does anyone have an idiot guide to the step by step process a Thai National with a young child has to go through to return to Thailand from the UK please?

They're aware they need to register at the Thai Embassy but then the guidelines get a little confusing regards the Certificate of Entry and booking flights.

Is there a health questionnaire that needs to be filled in as well?

 Why dont people provide links to their statements ?

Why do I constantly need to keep asking !!!!!!!!!

Do you have a link to that ?

Price paid by UK was in another article, will post when I find it.

"...and a 7-Eleven outlet in a PTT petrol station."

Glad they narrowed that location down.

Muang Thai Insurance T&C's say Thais only.

.....as do the first 3 companies listed by TQM Broker.

Seems a pointless thread as far as farang are concerned if that's the case.

Anybody know an Insurance Company insuring expats regards Covid as of now?

APETLEY ---Referring to your post #802--- Keep thinking about the simplest design as you do.

Other than generous pipe sizes, there is one factor I forgot; the steeper the angle of the plate obviously augers better for the turnover of the tank contents. This is really the "thermal pressure pump" if you'll allow. This would give George some grief how to set it, he being right on the equator? Can you enlighten us please George? What is the best angle all year round for steeper (as suggested) solar hot water panels without a pump and indeed solar P/V panels when fixed all year round?

Hi. Years ago I came across an online book where a guy had constructed a simple box with a network of piping and as you say quite upright to get a better flow. As an aid to collecting sunlight he actually fitted an angled mirrored strip behind each pipe. I wish I'd kept the link but he said it worked very well.

I've always thought about using a heat exchanger like that but even simpler. How about one at ground level and using the thermosyphon effect, heat rises, to let the hot water rise into a hot water tank higher up in the house, no need for the pump then.

recirculating the water for best efficiency requires a pump.

Agree a pump is more efficient at recirculating the water but interested in just how a effective a minimalist solution may be. The temperature of water in a garden hose can be unpleasantly hot so here in the tropics I suspect a passive siphoning effect of the hot water could warm a tank reasonably quickly.

Interested to hear from anyone with a better knowledge of physics who can crunch some numbers on the subject

Found a link with many diy examples like per attached pict.

My first thoughts about this one were the extra weight that the roof needs to support. Those tanks look like 200 Litres each so that's 400 kG plus the steel frame.

This is my setup. It is a flat panel heat exchanger made with copper pipe and aluminium fins encased in a wooden box with polycarbonate cover. size is about 1.2M square. The small pv panel supplies power for the circulation pump and monitoring electronics. The storage tank is 200 litre stainless steel with 50mm insulation. You will notice the temperature probe in a little cutout. Temperatures are usually in the low 40's which is a hot shower. Sometimes the water can be well over 50. The associated wiring is a bit scruffy because I'm too lazy to sort it out, having more interesting priorities to consider.
