and re the "heat exchanger"? sounds like a preheater -- not heat
exchanger as understood in the machine design sense.

daveb, first you demonstrated that you know nothing about Brewtus. Now
you demonstrate that you don't know what a heat exchanger is.

"Heat exchanger
From Wikipedia

A heat exchanger is a device built for efficient heat transfer from one
fluid to another, whether the fluids are separated by a solid wall so
that they never mix, or the fluids are directly contacted."

Or, from Taftan Data, "Heat exchangers are devices built for efficient
heat transfer from one fluid to another and are widely used in
engineering processes. Some examples are intercoolers, PREHEATERS,
boilers and condensers in power plants." (Capitals added).

That's exactly what Brewtus has, a heat exchanger. The fact that it is
used to preheat water running to the boiler rather than to preheat
water runing through the portafilter doesn't change the fact that it is
a heat exchanger. You said Brewtus doesn't have one. You were mistaken.
This happens to all of us. Learn to live with it. To accept it if
possible.

Karl "only 1 pidded Silvia, but knows a heat exchanger when he sees
one" Rice


Karl, When I was considering the Expobar Brewtus II at WLL it was
described
as a double boiler, not a HXr. All other Expobars are HX machines though.

afaik Karl never claimed it was a heat exchager machine but that it
contained one, here's what he said:
"since its much larger boilers, and the heat exchanger, defeat the annoying
wait for a pidded Silvia"
The reason WLL doesn't describe it as one is that it's not a heat exchanger
in the traditional sense but rather uses a heat exchanger to pre-heat the
water incoming to the brew boiler so providing better temperature stability.
