Even in the UK on a fairly hot day solar-thermal heaters can achieve temperatures of over 100C in the fluid (not always water), and there have been a few cases of either the heater or the tank exploding.

And all of those mentioned issues will only occur if the system hasn't been installed correctly.
That's why solar systems are installed with a tempering valve. (well they are here at least. Some places get 50°c + temperatures for days on end, night time minimums around 30°c, 15 hours or so of daylight. Not heard about any solar systems exploding due to the water boiling over). Gas & electric systems you just set the thermostat to an appropriate temperature (although apparently many instant gas systems also make use of a tempering valve).


Edit- i can see issues occurring if the system isn't full of water, but those same problems occur with electric storage heaters that aren't full either.

Happy Palindrome Week

Duh! I thought that was a bit weird...

That only works for the topsy-turvy USA random ordering of month-day-year confabulation.


That ordering really does look weird!

More sensibly and far easier to understand we have 28 (th of) 1 (January, in the Current Era year of) 2021.

And even that under normal rules is wrong. We usually read numbers left to right in order of magnitude. Therefore date/time should read;

year/month/day/hour/minute/second

... And even that under normal rules is wrong. We usually read numbers left to right in order of magnitude. Therefore date/time should read;

Yes, we are badly topsy-turvy...

The "year/month/day/hour/minute/second" is normally used for computer timestamps for logical consistency and easy logical date/time sorting.

However, common human usage is both backwards and forwards with the common format used of:

hour/minute/second, day/month/year.

And there are many years of hubris that conspire against going logical!

Yep, that is a big problem. Especially so for maintaining incompatibilities just for the sake of being stupidly proudly different...

The very good and consistent ISO standard is to use:

Year, month, day, hour, minute, second.

That format has huge advantages...

Here in the UK we don't have a very high regard for people from Essex, it's just East of London, but this has to an example of why they get their reputation.

But did the car enthusiasts actually come from Essex or were they just driven there as it was a great place to meet? :-)

Cheers.

Almost certainly from Essex. The Ford plant at Dagenham was the reason their ancestors moved out of the heavily bombed East End of London. Rusty gas guzzlers are in their blood.

Hope she learned something from this.
Woman who styled hair with Gorilla Glue attempts to remove it, documents trip to hospital emergency room

Late last week, Tessica Brown admitted on TikTok that she decided to use Gorilla Glue spray adhesive after running out of Got2b Glued, her preferred brand of hairspray.

...Even Gorilla Glue chimed in, telling TMZ that perhaps Brown could try saturating her hair in rubbing alcohol to remove the glue...
