I’m going to sneak out here in a few and go order a hood for my little 2X6. Of course I’ll be adding a pre-heater to it using the guidelines established in that Cornell paper published back in ’74.

Since I don’t have running water in the shack yet, the condensate will be used for a general clean up and wipe down (the wife hates it when I bring her a stack of sticky stuff to clean), the problem is that I don’t know how much condensate to expect. Provisions will have to be made for too much or too little.
There is a blurb in the paper about 980 BTU will generate 1 lb of condensate, but trying to wrap my head around the math this early in the morn has proven futile, better to just get the questions out there.
My pre-heater will be a parallel flow with 1.25” manifolds and about 30’ of ¾ copper. I figure that the hood with pre-heater and the addition of air over/under fire (slated for the ’14 season) should push me up to near 50 GPH. Sizing the pre-heater as stated should give ample flow for an emergency dump without being so large as to be inefficient.
So, if you have a 2X6 with a pre-heater of a similar size, how much condensate, in gallons per hour, do you get?
If your evaporator is larger, what is the diameter of the tube, how many feet of tube do you have, and what is your GPH of condensate? (I can extrapolate from there.)
