Alright guys I need your help on this one.....
Im looking into a couple of ways of externally heat a mash tun. So heres my question:
If I were to use a sanke 15.5 gallon keg as a mash tun and then place a larger cylindrical barrel with a larger diamenter, so that there was approx. 8" of space from the outside of the keg wall to the inside of the barrel's wall, and then attached to the inside of the barrel's wall four ceramic infrared heaters in the north west east and southern positions measuring in length 9.65" and in width 2.36" and putting out 1000watts at 240V would that create enough heat to one, hold a mash temperature for an hour or so? And two, would that deliver enough heat to raise temperatures if needed? e.g. step mashes.
Now I realize that many will ask why complicate life this much, Im just curious and would like to hear what the mathematically inclined have to say about this. As always thanks for your feedback.

Trying to heat stainless steel with an IR heater is very difficult because of the low emissiveity of the material itís one of the reasons that stainless steel pots donít work well on inductive ranges.

Paint the kettle black? If external heating is the key issue, then consider the use of heat blankets. www.mcmaster.com, catalog page 450.

Seems like a complicated method to heat, and maintain temperature. Why not just use a regular burner, or heating elements? It's cheaper and a more direct method of heating. If your worried about temp. loss, wrap the keg, it won't lose much heat over an hour or so mash.
