Saving water tap with hot water

[Did67]

The main cost of the hot water that has cooled in the pipe is not water! This is the energy that is dissipated in vain.

All the "cooled" water recovered, it is necessary to imagine that at the end of the drawing, it will have been replaced by as much hot water coming out of the calorifier, and which will be cooled in vain. Depending on the source of the heat, the cost and the pollution can be significant (it is zero if you have a CESI; it is high when it comes to electricity of essentially nuclear origin).

Now, it is to save, of course. I do not want to discourage anyone ... Just, basically, this qasiment change shit.

We must always remember that the bulk of our water consumption is ... indirect! It is the one "contained" in what we consume, from the ton of steel in our car to the kg of red meat steak. 3 liters of water to make a liter of beer ... And there, we can easily, by adjusting our consumption a little, save tons (and in general, this also goes in the direction of better health - cf meats red!).

Absolutely, Did67! And the solution proposed by Guyguy37, Use a permanent closure of the hot water does not solve the whole aspect of things.
I see an analogy with the recycling of glass bottles, in which one tries to recover the raw material, which is very little, and not energy (yet significant) which served to shape ...

Yes. This is the other example where we focused on a match, without seeing the beam!

[Germany has opted for the set and re-use - although transport / cleaning / sterilization are also heavy energetically speaking!]

[Ahmed]

I would have thought a straw to a match, but why not: D

The set is actually a stopgap; there is no really satisfactory solution to a brief use of a container of small volume for packaging a beverage product away from the place of consumption, otherwise the questioning of the model itself.

Ah but it was to remain in lignin !!!

Your comments confirm that we are currently in a phase where we prefer to act on the consequences rather than the causes.

One explanation is that it makes industrial interest.

As long as we do not have his head completely into the wall, industrial (and political) will make the most of the citizens of the string to make the costs of all the waste and recycling base of consumers.

2 anecdotes that illustrate this societal functioning grotesque:

- Many Conteners of recycling (cardboard, plastics ...), carefully filled by the consumer base that separate their waste, are mixed in the collection trucks to be transported and re-sorted on arrival! (I've seen lately): it would be more economical to re-mix the waste sorted for transport as the transport sorted separately.
Although several trucks with several drivers, plus the labor required for the collection, cost a dear, but perhaps it would be more appropriate for large industrial groups in charge of waste treatment make the effort to see this operation and organization to avoid unnecessary work for consumers ... but this requires costs!

- the famous collection of plastic bottle caps that allow their recycling and the financing of projects in the disability sector (http://fr.wikipedia.org/wiki/1_Bouchon_1_Sourire).
For having worked in one of the links in this recycling chain (ESAT), I found that the cost of collecting, storing, sorting, packaging, ..., are supported by the community for the primary benefit of the industry will recover this raw material for a nominal cost .

It would be more effective than industrial invest in cleaner solutions that these millions of plastic caps much of which ends up in the environment.


In short, the main savings we can make are not where we believe it!

Yes, GrelinetteThe economy works from what does not ... or, if you prefer, the micro economy a field day in what is nonsense in macro economic ...
It is far from the wonderful story of the rationality of the market economy!
