There is a very extensive habit that everyone is passed on by word of mouth, and that the industry started.
That strange tendency to have and generate social alert, to a pollution whose intensity does not exist and has not possibly ever existed.
You tell an installer that you are not following the imposed safety rules.
The poor ignorant man verbally attacks you and makes it clear that you are crazy and that you are reckless and a social danger. While his mother lives in a rural house with a pool full and in disuse, and surrounded by puddles.
This rare fear that does nothing but unleash what the industry intends to do.
Create new definitions, trends, regulations.
Obligations that, as always, end up generating a series of large expenses.
Expenses that always end up in the consumer's hand, and for the benefit of everyone else.
Anything goes to create business.
When someone knows that I have a home solar thermal installation, this is the first thing they ask me:
Is your facility protected against legionella?Most of the people who ask me this don't even know what legionella is.
If I ask them, many end up answering "I don't know, that's what I've heard out there"
Those who do know that it is legionella, always points to where the trade accuses, to everything that a consumer has in front of and can be attributed a maintenance obligation.
But what about the ponds? And the puddles? And the abandoned swimming pools? And the swamps?
Health is responsible for controlling this bacterium on drinking water.
It also advises us that the substances used for this control have a 48-hour guarantee.
Therefore, the notice refers to all those people who intend to bottle and store it.
Although nobody is taking into account how long the standing water remains in the underground conduits.
Nothing less than all the towns and cities, hundreds and thousands of kilometers.
And what happens in those towns where a pseudo-official controls the drinking water with a pH meter and nothing else? (Incredible, but there are)
What happened and continues to happen with the towns that follow the custom of consuming their rooftop pools? What happens and will continue to happen with the traditional representative sources that almost all the towns in southern Spain use? (whose maintenance is at most, an annual cleaning with bleach)
Has anyone ever been warned or liable for a consequence when storing your pool water for the following year?
Washing dishes in cold water and letting them air dry, could that be reckless?
As I have read, the supposed special antibiotic applied in drinking water to treat legionella does not end its existence.
What it does is control and lethargy the virus and supposedly in that state it does not act against our health.
Is this a coherent explanation? (We would have to be afraid of scrubbing)
That water is supposed to be in our digestive organs for long hours.
But it is that even after digestion, that water will be watering all our cells.
In the past there was no serious threat to cold drinking water, which in the past was stored on all rooftops (and from there was consumed).
There are still many rural houses that follow this custom without knowing exactly why. (The real reason for this tradition was based on being able to supply itself in the face of continuous water supply cuts)
Not even in this unhealthy use there were maintenance, and the now prohibited lead pipes were used.
Now the industry imposes on us the concern of a water that is consumed daily.
Whose temperatures will rarely drop below 30ºC.
When several regional councils consider that thousands of deaths per Xm2 enters normality, and does not activate any protocols. And now on our rooftops we have to protect ourselves from a horrible and deadly pandemic bug.
In the event that I want to avoid an alleged risk of contamination by Legionella (follow the regulations and their expenses).
I should have an electrical resistance in my installation turned on every time my water is consumed or drops below 60ºC.
Those times are, when much of that water is consumed, cold nights, cloudy days.
If at 8am the water warms up and the sun rises at 10am, the system does not know it, and it consumes the same as if it were 3 in the morning.
That is, 48º is not worth us, we must urgently heat up to those 60ºC, and maintain them.
This concept is confusing and contradictory when someone tries to sell me a green appliance.
They will sell me a solar heater, ecological, that works 100% with the sun, and has an electrical resistance that will work many times and behind my back.
That being the case, what I will be buying will be an electric accumulator with solar support. (although the pamphlet promotes otherwise)
I know that there are people who have realized that their solar heater heats the bill faster than water, and has canceled this resistance.
Then…. Is anyone able to calculate the energy consumption of?
Thousands thousands and thousands of electrical resistances consuming resources on roofs and rooftops.
Energy that is thrown away (not converted)
What is the benefit of many megawatts to keep water excessively hot?
Would anyone be able to evaluate the ratio of ‘risk’ VS ‘cost’?
Does this fulfill the theory of -> "kill a fly with gunshots"?
If we think about it a little ... whether or not that fear with risk inks against health is true ... .. there is a lot of fear ... but with very little foundation.
Do you really think Legionella is what they tell us?
