Hi,

Please be so kind as to explicitly state exactly which nutrients are lost when you boil water and how significant that loss (of nutrients) is considering you drink one coffee a day.

Just found an experiment on  youtube, two actually. Both plants stunted by the boiled water. I could do the experiment myself too. Well the fact it stunted the plants, I find convincing to say there is nutrient loss.

Heat just does that.

Never mind.

Why does turning the Sylvia off not work? Once it is off the noiler is off thus the water temp lowers, ytes?

ok

I do not know how to diagnose and find exactly what nutrients are in water but the content vary around the world ecause of the environment.

There you are!

Also there are the nutrients in the grind that are extracted into the coffee cup that are also maintained by a lower temp.

I've got a solution for you if you want to pull shots at 70 degrees celsius and eliminate a lot of guess work with temperature management: open boiler lever espresso machine. Stick a thermometer/temp probe into the boiler, wait until it gets to 70 then pull the shot, done. Sell the Silvia and pick up an old Peppina or Caravel.

That's a possible explanation but nutrients aren't the only variable that affect plant growth.  I can't view the link here at work as our proxy blocks Youtube.  The scientific method exists because it is a proven process for testing hypotheses.  Without viewing the link it's impossible to say whether or not the linked Youtube experiments are credible or not.

In any case, this discussion isn't relevant.  If you want to brew at 60 or 70 C that's your call.  It's whether you're happy with what's in the cup that matters in the end.  If you're going to stick with the Silvia a PID is your best bet unless you can find a thermostat set to the desired temp.  However, from what I recall the Silvia thermostats aren't offered at such a low temp.

If heat is a concern for you I'm surprised you aren't cold brewing as suggested above.  No heat (even 60C is applying heat), no risk of losing nutrients.

What you're looking diverges greatly from the majority so you're not likely to find any quick, easy or cheap solutions.  Compromises always have to be made and in your case you're going to have to compromise on ease and cost.

Yes, nutrients are not the only thing that effect plant growth. The experiment etailed, cuty water, stove water and microwave water.
he did not mention what temp he went to, boil for stove I imagine.
The stove water plants grew but were greatlt stunted, the microwave plants grew a bit better and the city water grew the best. I would say because no heat was applied but none the less they all grew!

There is no scientific data here so if you want live by that then that person must forget all other suggestion. I am satisfied to know that heat does kill nutrients. I believe it and we have seen it's effect in the plant world.
I am happy to sayt no scientific evidence or proof is needed when one watched the differences in groth in a plant.

Now do put this into the human world become a much harder thing. When I look around I see a not so healthy people. Everyone has flu's cold, sicknesses of all sorts. I think this is because of the refined food we all eat.

Thus I no longer eat this. I am happy with the effect in me, no colds, no sickness.

I am happy to eat healthy nourished foods.
I have no doubt illness like cancer are cause by malnourished foods now after what I read on food.

I have no doubt eating healthy food will prevent cancer. I hitnk it is relevant because I believe it alters the taste in coffee and all this talk is linked to that.

To much heat is a concerm yes but I am ok with a lower heat. I like a lower heat.

Yes one man showed me a thermo stat that is aimed at 65 degrees. I could buy that and switch this one I have.

I think you are right, I am going to have to just turn the macine of and lower the heat that way lol

There is another way to do this, it will cost you very little, kind of manual heat control and entirely manual and consists of rising temperature to 60C not reducing.
According to some of your theories, you would first kill the water and then reduce the temp to 60C?

What you will need is an accurate digital temp meter with a sensor and an electric button "momentary type" (good Amp rating).
K-type meter example   Click Here (www.ebay.co.uk)

The way it works: the sensor is mounted to the tank and sends temp read out to the meter, so you know the exact temperature of tank=water.
The momentary switch should be spliced in line, replacing the actual wires on the thermostat for brewing. (where PID's  SSR would connect-bypassing thermostat).

Power on Silvia and push button to start heating water and watch the temp rising and stop (pushing) when you reach desirable temp. See it as a manual over-ride of the thermostat, you activate the coil  manually. Momentary switch is obviously a must. You should be able to get any temperature you want.

I thought this concoction up when I was trying to figure out a no cost manual PID. Where you mount the button etc is up to you...You can probably tune it, design it better, this was a rough idea, because I put together a $50 PID system, so I stopped bothering

Thanks mate!

I dunno about theory! How heat kills it. It is the way of it.
No I would not kill the water, I simply would not run water to hot. Anyway, thanks for this!

Man that is awesome!
Could you make a tutorial on you tube, I am not familiar with the internals of a coffee machine and have no idea what I am doing.

Thanks tho!

I can't make a tutorial on you tube because I abandoned the project and ATM I am struggling with making a decent espresso and waiting for parts of my PID....no time.
It really is easy. All you have to do is to drill a 1/2" hole somewhere to install your push button, few connectors and some wire.
All the wiring info is here http://www.frcndigital.com/coffee/Silvia/SilviaBrewing.html

These two will give you all the info needed  below is a button type example...
