i just found this on another site ..
from New Zealand and imported by an company in Bellevue WA.
Thermette water boilers that work on the water jacket-flue
up the middle principle..i have seen these for campers in the
pint and quart size BUT--they also make them in a 30 liter
size with a tap..if you had a need for lots of hot water
this would be just the thing..anything that will burn can
be used to fire this up..they also have 10 and 20 liter models...i don't have a link but Google "thermette" should work

A little pricey for my taste but interesting nevertheless.

Poor Blast is going to be disappointed when he realizes that you didn’t simply misspell “Thermite Water Boilers”.

Looks like my coffee can cooker.

15" tall, about 3.4-4" wide, and it ONLY weighs three pounds. Yesh! It would be great if you had a vehicle or horse to carry it, but packing it might not be the most efficient. Also, if you are going to refill it, how long does it have to cool before getting dunked again?

RAVEN..
like most bits of gear it's made to fit the needs and
abilities of those who chose to use it..the New Zealand Army
used the thermettes widely in WW II...Irish fisherman were
using their version at the turn of the century..in a sitution
where there was no fuel to be spared or had, it would be worth
it's weight in gold,,well maybe silver--anyway..there are
thermettes made of tin that are lighter..and--not every bit
of gear made for survival needs to fit in a band-aid box with
10 other things..i don't have a BOB..i don't think i'll ever
need one,but if i lived someplace where i had to get in my car
and try to get away from a disaster of some sort i would want
one of these in my trunk along with the canned food and tent.
but then again you have seen my honking huge packs---

I agree. And if I didn't have a wood stove, I'd take a look at them. I have a wood stove, and I probably will be taking a look at them later on, for bugging in. But the way they were phrasing it to me made it sound like they were being used by packers.

I have not used the Thermette versions of this chimney boiler, but do have two Kelly Kettles. They are really excellent devices, particularily for an emergency kit. I carry mine as part of my car and emergency communications kit. There is always plenty of dry enough waste wood to boil water.

One of the 10L sizes would be a great addition to my communications kit. Coffee and tea can really buck up an excercise or a disaster response.



I have an article on my 1-pint Kelly over at the outdoors-magazine. I added the larger Kelly last year but have not updated the article.

Highly recommended devices.

Love my Kelly, too.
On the weight issue - no stove, no fuel, no fuel bottle, no boiling pot, no lid -- well . . . let's see . . . not so bad after all! Then again I come from a long line of Irish fishermen and we're just stubborn!
