We will fit "pid" temperture control to any HX (heat exchanger) espresso
machine for $345.00, with a six month warranty, parts and labor, on the
entire unit.

We've pimped over four dozen machines, for four dozen happy users, so we
know what we are doing.

typical Harmon B.S.

I have plenty of reference owners of machines so equipped.

1 'pid' Zaffiro and 2 'pid' vetranos sold THIS week.

Howdy Jack!
I forgot to ask in my earlier response but do you know if anyone has
compared, by measuring over a protracted period of heavy use, the temp
stability of a commercial-sized boiler equipped with a pstat and then
converted to a PID; or even using a prosumer-sized boiler so modified?

I'd be surprised if there was much difference in temps, hour by hour,
on machines equipped with either device. The thermal mass of this size
boiler on an HX machine would itself insure temp stability in the
boiler, as the only water drawn off is that used for steaming & the
occasional draw of water for an Americano

The main benefit of adding a PID to an HX machine is in lining the
pockets of installers.

It affords a measure of control -- and reliability -- not possible in
conventional pressurestat machines.

"Jack" seems to understand.

Howdy Jack!
Your response reminds me of why I keep two espresso machines on hand.
One is a PID'd commercial HX machine that I use whenever I need to
pull shots and steam milk for groups of people and the other is a
PID'd Gaggia Espresso that I keep for my everyday use.

The PID on the Gaggia lets me run the preset brew temp up and down as
I try different SO's or blends (doesn't always matter, but
sometimes...). This would be virtually impossible (or at best very
time consuming) to do with the larger boiler in the HX machine. Oh,
and since I have the HX powered up 24/7, I use it to steam milk so I
never have to mess with the Gaggia's preset.

As for adding a PID to an HX machine, I agree with what's been said in
previous threads; adding a PID to an HX machine doesn't add enough (if
at all) to the machine's temp stability to make it worth the effort
and cost. A PID can be a worthwhile addition if it's purpose is to
reduce the noise level inherent in pstat equipped machines.

How does it work to steam with a PID'd HX machine? Do you have to dial
it up to steam, then back down to brew, etc., like a single boiler
machine? I make a lot of milk drinks for my wife, so not sure PID
would be the best solution for me. . .

No, absolutely not. The PID takes the place of the pressurestat and the
boiler remains at the same (steaming) temperature as it was under pstat
control (except it stays in a narrower range) or at whatever temperature
you set it.

If your machine has weak steam at brewing temp, you could dial it up a bit
to steam and then back down again to brew. Or what I do in the summer to
save energy is dial the machine down to around 105C to idle during the day
when the machine is not in active use.

But most people just set their PIDs for what they view as the optimum temp
for brewing their usual blend and leave it at that - there's no need to ever
touch the set temp unless you want to. You could even install the PID out of
sight (inside the machine) so you'd have no awareness that anything was
different from a pstat.

Certainly "pimped out" is a valid usage of the term, but a little 'old
skool'.

newer usage: i.e. "Pimp my Ride" -- the MTV series. not "Pimp out
my ride"

some say pimp has become a verb much as google has.

If you mean "customized", I think the phrase you're looking for is "pimped
out".
