But, I\'m sure you can understand that in most instances, people are not willing to re-plumb their home to make use
of a recirculating pump. Also, recirculating the water is preferable to dumping in the drain. In my area the cost for sewer
is almost 2 times the cost of the water.
btw, could you list those multiple kinds of wrong?

you generally don\'t want any risk of getting contamination, including your hot water, into the potable cold water system

So hot water is not potable??? I never knew that. I guess everytime I run the hot water, I should then run the cold water a while to clean the tap?

This whole idea of running hot water through the system to keep the water in the pipe hot is silly. They make instant hot water heaters for sinks, that do this job and only need an outlet.
Not everybody can use those; they need an ample electricity supply.

For a sink, it uses a standard 120V, 15A connection. Who doesn\'t have that??? Are you talking about some third world country? If they can\'t power this unit, how could they possibly power a hot water tank? Mine is 240V, 18A.
Most houses here have a contract that limits total instant power to 3.5
KW. It certainly is not a third world country. You can have more power,
up to 15 KW, but it is significantly more expensive.

Hot water tanks take 1 KW, maybe two if the tank is big. Mine I changed
to take 0.5 KW.

It must take forever to heat a tank of water. Sounds rather dysfunctional. My microwave oven uses more than 0.5 kW and it is some 40 years old.. A hair dryer uses 1.44 kW. I guess you have to turn off all sorts of things to use a stove. But then maybe you have gas. No, if that were true, you would have a gas hot water heater.

Sorry, this is not very easy for me to digest. The water uses the same amount of energy to heat up if you do it at 0.5 kW, or 5 kW. I just can\'t picture how it can be practical at 0.5 kW. I can take a shower and have a tank full of hot water in an hour. At 500 watts, it takes 10 hours.
Actually, it takes about four hours, the tank has 50 litres. Runs on a
timer during the night, if I activate it. I prefer the gas fired on
demand hot water system (yes, I have both systems). There is only one
person in the house, I don\'t need the hot water tank to reheat till next
day.

Wow! I\'m sorry, but that\'s clearly not first world. Or something is wrong with the math. 4 hours of 500W is 2 kWh, or 7.2 million joules. Divide by 4.186 (water specific heat) to get 1.7 million g°C, or 1,700 liter°C. That\'s around 34 °C for 50 liters. So room temperature to 130°F or about 55°C.
Well, if it starts at 20°C then in 4 hours it goes to 54°C, which is hot
enough to burn the skin. If the tank was not fully spent, it goes up to
70°C, which is about the max temp I set.

(room temp typically 20°C)

So you live somewhere hot like Puerto Rico, where the water never comes in cold. Still, the math doesn\'t lie. I don\'t know why you would want 70°C water. That\'s dangerously hot. 55°C will give you a first degree burn if you keep your hand under it until you are forced to pull it away.. 70°C will give you second degree burns, even if you pull your hand away. Not the best idea.
Because a 50 litres tank at 70°C lasts a longer shower than a tank at
50°C, or two people. That\'s how it is done here. You simply mix the hot
water with cold. Me, I set the tank to a hotter temp in winter than in
summer.

hope you don\'t have hard water

At least you have electricity. So 2.5 world.
Interesting how you judge countries.
We have solar heated water that can get up to 90°C. The solution is to use a \'tempering valve\' which mixes the hot and cold water so that the outlet temperature is 55°C to 60°C <https://www.google.co.za/search?q=https%3A%2F%2Fwww.takealot.com%2F15mm-solar-tempering-valve%2FPLID71231164>

So there is not room in your home for a larger tank, so you set the hot water to dangerously hot temperatures to provide longer showers. I seem to recall some comment from you about others being wasteful. Here I thought you were talking about taking shorter showers. But clearly that\'s not the case.

You can install an automatic mixing valve to the tank, or at point of
use.

Not sure what a mixing value does. Will it prevent overly hot water from coming out the faucet? The ones I\'ve seen have a setting, which can be set to very hot. If someone doesn\'t remember to turn it back, you get scalded.

There are many cases of children and people who are otherwise infirm being scalded by overly hot water. That\'s why, in the US, it is recommended that the hot water tank be set no higher than 130°F (55°C). That\'s a temperature that gives you time to prevent scalding.

The only reason to set a higher temperature in a home hot water heater, is to allow the hot water to last longer. But the same thing can be done with a larger tank, at a lower temperature. A lower temperature saves on heat losses too.

Sadly, yes.  I recall, growing up, it was common to \"sweep the
driveway\"
with a hose (instead of a broom).  Someone doing that here would
promptly
be told to stop (by concerned neighbors).

Yes, we should do that here as well. We typically \"mind our own
business\".

Oh, the neighbors would *politely* draw your attention to your waste.
We realize that people who \"aren\'t from around here\" likely don\'t
understand the preoccupation with water; what was normal for you in
the last place you lived is likely not the same, here.

However, someone who repeatedly ignores such \"prompting\" can
just as easily find a uniformed police officer making the
same \"threat\" -- with legal consequences!

Oh, I was just thinking that there are cultural differences. Most
people here would think \"mind your own business\" and say nothing, even
if some/many bitch in private about a neighbour that wastes water.

For other things, yes.  Leave your trash cans out at the curb an extra day
and folks will grumble *privately*, but likely not comment.

Water, OTOH, affects each of us.  That\'s *my* water you\'re wasting!

There are too many houses with pools (when the beach is meters
away), or have a well kept grass garden.

Thankfully, grass is obsolescent (though still not obsolete).  The
diehards who are used to a \"lush green lawn\" move to artificial grass
(why not just PAINT the dirt green??)

There are other plants that keep the lawn green while using little
water. Not all of them allow to walk on it, though.

We have crushed granite as a ground cover.  Lots of plantings *in*
the yard but each has a dedicated irrigation line to ensure the
water *just* goes to its roots.

Xeriscaping (low water use landscaping) is common.  E.g., we have a
couple of large (15 ft) Texas Mountain Laurels adjacent to the
front door.  They are *never* watered.  Yet, perpetually green.
(in bloom, presently.  very pungent.  they smell like grape soda)

https://nativebackyards.com/texas-mountain-laurel-tree/

I was thinking of this one:

<https://plantasflores.com/cactaceas-suculento/carpobrotus-acinaciformis/>

<https://en.wikipedia.org/wiki/Carpobrotus_acinaciformis>

Or similar.

....

They, of course, feel that someone else should solve THEIR problem.
Like buying a diesel truck and discovering the nearest station
that sells diesel fuel is halfway across town (d\'uh... didn\'t you
think about that BEFORE you made your purchase?)

Heh.

(around here, diesel is found on every station)

It is, here, as well.  But, you might live someplace that doesn\'t have
any nearby stations.  (there are areas that don\'t have electricity
*or* municipal water)

One common strategy folks adopt as they get older and accumulate wealth
is to move \"farther out\" -- larger plots of land to build bigger homes,
etc.  Then, as they get older still, they realize it\'s a 30 minute drive
to the nearest hospital and they are increasingly likely to *need* to
make such a drive, \"unexpectedly\".

Ooops!

Yep.


Some folks have summer homes on the mountain and winter homes in town.
Pity them if they have a medical emergency in the summer as it\'s a
helicopter ride to the nearest hospital (or, over an hour in a car).
In addition to the expense, it\'s still a long commute as the
helicopters are based AT the hospitals (so they have to run up the
mountain, pick up the pt and then return back down).

[I can be at one of 4 hospitals in 15 minutes -- obeying all traffic
signals.  Give me an hour and I can be at one of 10!]

[Seems to me, you\'d want to be sure of that before sinking a few
hundred
kilobucks into an investment!]

Here there was a spree of building golf courses with lots of houses
around to sell mostly to British folk.

We have some \"world class\" courses -- well, at least some \"celebrity\"
tournaments are hosted on them.  But, it\'s largely a waste of real
estate.  The private ones are usually associated with a \"country
club\" (a means of transfering money from folks who want to APPEAR
wealthy to people who delight in giving them the impression that
they *are*!) with membership dues, requirements to spend $X monthly
eating *at* The Club (if you fail to spend the money, you are just
billed for it AS IF you had dined there), etc.

SWMBO used to golf (recreationally) ages ago.  She\'s found more
productive things to do with her time, now.  And, other neighbors
have realized that their bodies aren\'t up for the task (and NO ONe
wants anything other than a 6AM tee time during the summer months...
it\'s already 80F, here, now).

Yep, but it is not only the golf course itself. It is a whole
residential complex. The course, one hotel or more (different luxury
levels), individual houses (probably sharing a wall), apartments,
shops, restaurants, bars, discos, a Telco (to provide British TV
programming to them),... lots of things, huge investments. And lots of
grass, apparently the British love to see green even if this is almost
the desert.

Here, the course is just a centerpiece.  Unless you *join* the associated
country club, you\'re no better than any other plebian.  :>  The difference
is, you likely look out onto a large expanse of grass when you step into
your back yard.

Dunno what they do now, after Brexit.

each of the country clubs/courses are located just by looking for \"green\"!

Of course that here houses are smaller. Your country is empty, land is
cheap. And our tanks are put near the ceiling: try to do that with a
heavy tank.

LOL!!! You are a trip. My pressure tank is on the ceiling! We mostly put hot water heaters in the basement, or under stairs or even in the attic. No one has them in their living rooms.

(in bloom, presently.  very pungent.  they smell like grape soda)

https://nativebackyards.com/texas-mountain-laurel-tree/

I was thinking of this one:

https://plantasflores.com/cactaceas-suculento/carpobrotus-acinaciformis/

https://en.wikipedia.org/wiki/Carpobrotus_acinaciformis

Or similar.

\"Ice plants\".  We tried a couple of them.  But, they get really stressed
in the summer (or, maybe it was the winter??)

The TX MTN Laurel just keeps chugging along.  We have three \"trees\"
(exceedingly tall shrubs?) that line the entrance to the front of
the house.  They are arranged in such a way that they trap the air
on the front walkway -- after perfuming it!  It is really intoxicating.

They are reasonably prolific seeders.  But, the \"volunteers\" are
really hard to transplant; disturbing their roots is the kiss of
death.

Dunno what they do now, after Brexit.

One of the more well known clubs, here:

 From the air:
https://www.google.com/maps/search/ventana+canyon/@32.3204583,-110.847146,1278m/data=!3m1!1e3

Zoom out to see how brown everything is, normally.  You can spot where
each of the country clubs/courses are located just by looking for
\"green\"!

What does \"RM\" stand for?  Rue...?  And, why some in yellow and
others in
green?

RM? Where?  :-?

On the map you cited.  RM### for roadways (?)

Ah. \"Región de Murcia\". That is, \"RM-F30\" is a road that is owned and
maintained by the Murcia Region, number \"F30\". Dunno what the F stands
for, maybe avoiding three digit roads. Huh, no, I see \"RM-313\".

Dunno why some in yellow and some in green. Good question. Maybe
\"quality\" of the road, the width. [...] Found it. Black on yellow is
regional (autonomic) third level road. White on green, same but second
level.

Autonomic 1st level roads are \"CL-XXX\", where the X are numbers, black
letters on orange background.

\"N-340\" is national road 340.

\"AP-7\" is \"Autopista de Peaje\" number 7, ie, toll highway number 7.

So there is not room in your home for a larger tank, so you set the hot water to dangerously hot temperatures to provide longer showers.

You can install an automatic mixing valve to the tank, or at point of

Not sure what a mixing value does. Will it prevent overly hot water from coming out the faucet? The ones I\'ve seen have a setting, which can be set to very hot. If someone doesn\'t remember to turn it back, you get scalded.

There are many cases of children and people who are otherwise infirm being scalded by overly hot water. That\'s why, in the US, it is recommended that the hot water tank be set no higher than 130°F (55°C). That\'s a temperature that gives you time to prevent scalding.

The only reason to set a higher temperature in a home hot water heater, is to allow the hot water to last longer. But the same thing can be done with a larger tank, at a lower temperature. A lower temperature saves on heat losses too.

Dunning Kruger strikes again.

I have not heard of any one being scalded here. Maybe we are just
smarter :)

No, just more arrogant.

LOL.



Oh, we also have smart mixing taps.

And smart flash gas heaters that provide a constant temperature flow, on
demand.

So they don\'t produce 70°C water? That\'s the only thing you\'ve said that is smart.

Sure they do, if you adjust it so.

Of course that here houses are smaller. Your country is empty, land is
cheap. And our tanks are put near the ceiling: try to do that with a
heavy tank.

LOL!!! You are a trip. My pressure tank is on the ceiling! We mostly put hot water heaters in the basement, or under stairs or even in the attic. No one has them in their living rooms.

Again, world 2.5.

We put hot water tanks or heaters near the places where the hot water is
used most. If gas, on the kitchen. If electric, in the main bathroom.
And near the ceiling, so that they don\'t use floor space.

Where it makes sense :p

At this point, you are just being silly. You live a life style that has to preserve every square foot of space, and squeeze every penny on your electric bill. I talked to someone else in Spain who had similar restrictions from the power company. Many places don\'t have such restrictions. The power company provides 50 kW connections for most homes in the US. That doesn\'t mean you have to use 50 kW. It just means you can have a proper hot water heater that just runs when it needs to, rather than being run at the pleasure of the power company. We have room in our homes to put a hot water heater under stairs or in the back of a closet, without worrying that we are taking up valuable floor space.

I\'m sure you manage to deal with these issues, but life is better when you just don\'t need to worry with it.

I pay $0.12 per kWh, with a $14 a month service charge. I turn off my water heater when I\'m away for a week, but it actually saves very little money, maybe $2 a week, at most.

Life is good when you can have things, and not worry with them being scarce.. I would hate to have to turn my water heater off and on every day. Being on a timer is fine, until the timer gets off track.

Yes, world 2.5.

\"Owned by\" is an interesting way of putting it. That may, also, apply
here. But, we tend to think of it as \"maintained by\".

E.g., there are roads that are maintained by the city, county, state,
federal government -- as well as private roads (e.g., in some subdivisions,
the homeowners are responsible for the maintenance of the roads that
interconnect their homes).

Some roads are \"toll-ways\" (pay for use) but most are open for general use.

Dunno why some in yellow and some in green. Good question. Maybe \"quality\" of
the road, the width. [...] Found it. Black on yellow is regional (autonomic)
third level road. White on green, same but second level.

Second vs. first vs. third? Does this have anything to do with the
quality of the road, how wide it is (lanes), the type of traffic it
supports, etc.?

Here, that distinction is separate from the road\'s \"ownership\". E.g.,
the city road that my subdivision empties onto is 6 lanes. There are other
city/county roads that may be just two lanes. The interstate (federal)
highway to the next metro center is no larger than the road by my
subdivision -- but, the speed limit, there, will be 65 whereas here it\'s
45 (which means 55) and the road construction will be of a higher quality
(better signage, wider shoulders, smoother/more-durable pavement, etc.

He thinks getting the same result in a dumber less efficient way is better. No amount of explaining educates someone that isn\'t even interested.
