Topic: Let down by Temp of New Technivorm in Georgia (10 msgs / 231 lines)
1) From: Tim Brown
Today (2/5/09) I received my new Technivorm *Moccamaster with Thermal Carafe
*and have a concern about the water temp.  During the initial cleaning
process I tested the water temp of the water coming out of the shower head
and the water in the carafe during and right after the last drop.  The
highest temp was 186 degrees from the shower head and water in the crafe 183
with two different digital thermometers and this was without coffee grounds
in the holder too.
Yes, I pre-heated the carafe with boiling water for 5 mins prior to running
each of the 3 cleaning brews.
After a lot of research and reading great reviews how this machine would
heat water to the correct temp (i.e. 200) am I being too critical about the
big difference in temp for such a PRICEY machine.  I could accept maybe a 10
degree difference but is a 14 to 17 degree lower temp difference for this
BRAND New Machine for the first 3 times it has been used.   Should I return
it and ask for a refund / replacement or go with a totally different brewer.
I am a total newbie and convert to "how everyone should enjoy" coffee.  Not
only did I get the new Tech., but also a top of the line burr grinder (I was
using an early 1990's Krups blade spice grinder) and the Nesco home
roaster.   The grinder and roaster worked Fantastic and I have two batches
degassing as I type.
Any advice would be greatly appreciated about the Tech concern.
Thanks,

Did you check the manual?   Is there a way to adjust it's thermostat?

Tim,
If I understand you correctly, you took tempature readings running hot
water through your TV for the flushes.  The water will be hotter when
you run cold water  like you should doing a proper brew.  My TV reads
between 198 and 201.  When flushing with hot water, the water moves
too fast through the heating coils to reach full tempature.  Try
taking the readings running a cold water tank through your new
machine.  I think you will be happy.

That is not an option / function available on this machine to my knowledge
and the manual is a half sheet of paper folded in half...lol

Les, I think that the hot water was used to pre-heat the carafe.  I don't
think Tim mentioned whether it was hot or cold water used...
but then again, I've been wrong before...

Hey Guys,
I used *cold water to do each flushing* and boiling water to the rim for
Pre-heating the crafe for 5 minutes and I put the lid as well....dumped it
after 5 minutes and begin the flush with cold water right then.
I appreciate your reading my post and trying to assist with my concern.
This morning for my first "coffee brew" the readings were the same and I
used cold water for the brew and pre-heated the crafe for 5 minutes with the
same steps I mentioned here above.  Needless to say the spouse and teenagers
weren't impressed after all of my boasting about having this specific
brewer...the kids opinion goes in the trash with most of the noise from
their 17 and 18 mouths but its the "Other One That" I have to handle with
care and justify my purchase as I'm sure some of you know what I mean.  LOL!
Maybe I should contact SM and see if I should return it or if these readings
are acceptable. I am just very disappointed that this barely performs better
than my 4 yr old Starbucks brewer.
Thanks again,
Tim

Les,
I forgot to ask in the other response did you take your readings from water
coming out of the "shower head and or crafe"  My readings are NO where near
those.

"Did you check the manual?
Is there a way to adjust it's thermostat?" No.
The last time I read the manual ~2 years ago, nothing was indicated about
making any adjustments.
The last time I had it apart ~1.5 years ago, there are no adjustments.
[I had been seeking to incorporate some means of adding heat to the brew
basket, because, while mine generates exactly 200 F brew water out the a=
rm,
the brew basket shows 187 F Max.]
But the coffee tastes excellent in spite of the numbers. Numbers or coffee,
it's up to you.
In my espresso machine, the pump and the heater are totally separate- it
will pump water through the grounds even if the heater has become a doornail
and doesn't heat. The vibe pump easily pumps faster than the heater can add
heat to a cold water supply.
In the TV, the Heater >is< the pump. The water doesn't advance until it's
hot, if it isn't limed up. If it's limed up, the temperature drops coming
out the arm. At that point, twice in my machine's history, the flavor
decline is shocking. White vinegar lets you bypass all the palaver and
expense of the marketing types to buy their overpriced snake oil.
I have purposely put warm water in the reservoir, up to 100 F, like my
espresso machine. The TechniVorm perks faster, but the water temperature out
the arm stays exactly on 200 F. It has never brewed at 200 F. It has
brewed great coffee for hundreds of pots. I have forced  200 brews in the
press pot beakers using a microwave oven. More hassle, no benefit to the
taste.

Well, OK- where can I get the PID heat tape?
I know- McGuckin's in Boulder probably has PID heat tape, or they know
exactly where to obtain it... They have everything else in stock!
