One guy made a test between two cooking systems where the heat exchanger system weighted 143g more than the one without, but used 4g less fuel per 1l water boiled (11g vs 15g). He boiled 2l on a regular day, with a total saving of 8g per day if using heat exchangers. 8g saved fuel per day meant almost 18 days on the trail before he saved weight from the 143g extra that the heat exchanger cooking system weighted (143/8). Of course the amount of days before you save weight depends on the weight difference between a system with heat exchangers and one without. Less difference means you save weight faster.

This is with a Snowpeak Gigapower and an Evernew Ti pot:

I've looked at jetboil clones because they're about $50 these days, but they are definitely heavier - I could spend that money on a Ti pot.One guy made a test between two cooking systems where the heat exchanger system weighted 143g more than the one without, but used 4g less fuel per 1l water boiled (11g vs 15g).

I would personally use one even if it weighed more because I hate buying stupidly expensive little bottle of gas

Orion wrote:I think that what you're trying to do will likely increase the efficiency somewhat. Or, for a given efficiency, increase the speed. But whether it's worth it or not is hard to say. I would guess it is not worth it. But regardless, you will probably find it entertaining to play around with.

Ooh, maybe - can't remember the exact massdrop price but think it was around the 60 usd mark. 100ish seems to be standard locally, which won't break the bank but is a bit rich for just a stove...Lamont wrote:Is/was not the Windmaster a similar price at Toms outdoors compared to massdrop?
Soto seem to be the champs.
