Dean,

IF they will sell them to you, the cost is going to be the real controlling factor.  These units are used in military and tourist subs.  You can purchase a lot of wool underwear for the difference in cost plus the special requirements for shipping.

Jay the heat is one of the things I was interested in. My 39 degree water temps do that.

Is the flammability a big concern?

The lithium hydroxide cartridges are of a larger diameter as compared to the much more common Extend-air slaked calcium hydroxide units.  The LiOH cartridges are MUCH more expensive with a proportionally extended duration time.  As a by-product, they produce a lot of heat.  In addition to the downside of the cost, exposure to water makes them flammable/explosive.  The other cartridges can be acquired through many SCUBA shops.

  Just a note...Lithium Hydroxide canisters were aboard my submarine in case of emergencies. I would assume that the navy did extensive research and found these to be the best purchase for the limited space available.
 
  My .02 cents
