For your interest, some of the best quality espresso machines (e.g.,
Faema) use an electric pump to pressurise cold water, which is then fed
through a heat exchanger before it reaches the brew head. The water in
the boiler acts as a heat reservoir but doesn't actually end up in the
coffee. If you search for a history of the Faema company online you
should find more information. There was also a Faema dealer who had many
detailed pictures of Faema machine parts online, but I'm afraid I can't
remember the address right now.

I've always hankered after a Faema E 61, but can't afford it. Maybe one
day I will pick up a broken one and restore it.


What I am looking for is the ability to have a machine that is able to
squirt water through coffee at what ever temperature I want and what ever
pressure I want. Commercially available machines have several drawbacks,
the price is one and the "tweakability" is another.

I built a roaster I cobbled together out of a scrap gas BBQ grill and now I
want to build something that will give me a brew that tastes as good as my
beans smell.
