110v small bunn hw tower probably cost under 400
i know coleman has a propane tank heater one that might work? but i think you could get 110 where ever you are, if your looking for max recovery time then maybe a 220v fetco or bunn
but i think a 110 might do it

Great topic. I will build a commerical cart when time allows so this is a hot topic for me. I have not studied the existing carts that are out there now so I'm very green on this question. I want to duplicate my commercial set up but is that possible? All water to my espresso machine is filtered.
If I could dupicate this setup the water for the presspot would come from the water spout on the espresso machine. No recovery time and pure water to boot. Now if the cart doesn't have a 'spro machine none of what I said here counts.

when you say filter for espresso it should be a water softener or an r/o system, you dont want to soften water to a coffer brewing device the reason being is if the water is to soft the lack of minerals in the water wont pick up the coffee as well i know this is a vague description but basically you need the hard minerals more so in the coffee, see http://en.wikipedia.org/wiki/Solubility . . . if you wanted to go nuts you could always contact someone at this site http://www.scaa.org/awards_golden_cup.asp#judging for a best water hardness level im sure they'd know they do a test to see how much coffee you can dissolve in water by using a tds meter (total dissolved solution) the two main factors in this are 1. temperature (does your sugar dissolve well in iced tea vs hot) and 2. hardness of the water. you could say the amount of coffee (grounds being used aswell but im not getting into that nor counting it in this discussion)
although you could just use a normal in line filter that shouldn't affect your gpg

hope this helps

Bill, Thanks for the thoughts on this, although I did my homework on my first project. We have between 250k and 300K invested in this coffee shop so no stone was left unturned. Our water was tested and no softener in this system. I'm using everpure filter treatment in front of the Faema. I would like to do something like this for a portable tow behind commercial cart. As soon as I have a spare 20K.???? Lets see, how much is a good used two group LM rebuilt plus all the extra's to build a nice cart, you get the idea.
