Subject: How do I reduce the temperature of the Racillio Sylvia?
 

Hello!
How do I lower the tmp of the water that comes out of the Rancillio group head?
Can I open it up and reduce the boiler temp?

I know about PID and I do not want that.
Right now I reduce the temp by turning the machine on and doing a blind. Turn it off. When I turn it back on the temp sits around 70 degrees rising so I work fast to pull my shot.

Is there a way to actually reprogram the machine to sit lower than 90 degrees?

Thanks

I did not search for a specific thermostat, but could find a lower temperature brew stat.  What are you trying to do?  You could also probably learn a way to flush a certain amount bringing in enough cool water to lower the temperature, trial and error and taste.

I just want the water that runs out of the group head to be lower, it tuns at 90 degrees.
I was thinking maye one could open up the machine and maybe there a way to program the temp lower?

I am not sure why lower unless you have measured group water temperature, but look here

Click Here (b2b.lfspareparts724.com)

I saw 88C and 85C and quit looking.

The thermostats click on and off, open and close a circuit, so no programing.  See bimetal thermostats.

Hey Petey:

Sounds to me what you are really asking is how to control the brew temperature in a non-PID'd Silvia.  This is a subject that has been discussed in great detail, with lots of good advice / suggestions on this very forum.  

Try searching for temperature surfing and reverse temperature surfing.  Either technique will provide a rather repeatable method to to brew at a desired temp.  Of course, the fact that there is some ritual associated with this technique on Silvia (or any other SBDU machine) is one of the factors associated with utilizing a PID as a more pragmatic (and accurate) means of brew (and often steam) temperature control on Silvia.

For starters, take a look here

The stock thermostat on Silvia is not "programmable" in any way. It has the characteristics of lower and upper limits as functions of it's design, that provide the respective "on" and "off" for the heating element.  Unfortunately, the temperature range between these limits is rather large (dead band) with either extreme of the limits either too cold or too hot to brew espresso.  So, the idea of temp surfing, is to capitalize in one way or another on an identifiable part of the heating cycle (either full on - when the boiler shuts off at the high limit, or full off - when the boiler kicks on at the lower limit) and then initiate the brew at some repeatable time interval form these points (i.e. during the temperature ramp-up part of the cycle, or cool-down part of the cycle).  Good technique and attention to detail (time) can produce repeatable temps for brewing.

Hope that helps a bit!

Best,

Rick

Thanks Rsinger yes I htink you are right!
The reason I wanna do this is because heat kills water! I wanna keep the nutrients! I am onto a igh nutrient diet now and I love it!

I have just invested in a water purifier and am now putting fresh pure water into my coffee! amazing!
Will look at the link with Kat yes seen many of her vids lol

thanks!

Are you mocking me mate! Here is an idea go grab the popcorn and educate yourself on nutrients! Also here is another little thing you can do. Go burn the crap out of your water and compare it to natural spring water found on a mountain! Ignorant prick.
