Default Pot/Kettle shape

I've founds no end of threads discussing the merits of various volumes of kettle.

I found a place today that's selling short fat pots for sensible money. My concern is that almost all the photo's I've seen on here show pots/kettles that are normally taller than they are wide.

Is there a reason for using a tall skinny rather than a short fat one?

Yes, there is a reason. As the kettle diameter increases, so does the surface area of the boiling wort. Wider kettles will have more wort boil off. See post #10 here. If the kettle is really wide and short, the boil off for a batch may be excessive. What are the dimensions of the kettle?

Kinda like women, tall and thin work fine...but shorter and wider can work very well also You need to account for additional boiloff with a shallower pot. It's personal preference, I prefer a taller skinnier pot mostly for a more reasonable footprint.

I see that beersmith allows for varying boil off volumes in the brewhouse setup. This leads me to believe that it's not really critical.

I also think that a larger surface area might help with DMS.

The pot is 14.23 gallons filled to the very brim which makes it a bit bigger than I wanted but it's priced very well for South Africa at around $80

It measures 19.4882 inches accross on the inside and is 11 inches deep.

Life has happened and I am still kettleless.

I have an opportunity to pick a new 50litre/13.2 gallon coffee urn with a 240v 2500w element. LINKY to a similar model The one I can get is going for under $100

Some of the advantages:
Built in sight glass
built in controll to turn the heat down
has a "plastic tap" which means its predrilled.

The BIG question, is 2.5Kw going to be enough to do 5 gallon BIAB batches?

I would guess yes, 2500w is adequate, you won't set any speed records, and you may have to disable a thrermostat to reach boiling temps, FWIW IMHO.
