Heat Exchanger

Increase the efficiency of your MSR stove up to 25% with the MSR Heat Exchanger. MSR's waffled design channels heat from the stove up the sides of the pot, increasing the heated surface area of the pot. This means your water and food heat up faster, and you save fuel. Use the Heat Exchanger with all MSR 1.5- and 2-liter pots (with the exception of the Titan 1.5-liter).

  • Reduce cooking times with this stove attachment
  • Brass material increases heat transfer
  • Adjustable dial offers a secure fit
  • Made in Seattle, USA

I was like... WTF?

    I purchased one of these and was thinking it was going to be great to use instead of the clumsy aluminum that comes with MSR stoves. I went out to the garage and pulled out my different pots. This one is too big and so is this one.. Etc.. Etc.. I finally get down to my itsy bitsy pots and it finally wraps around them. I ended up getting a Reactor stove in the 1.7L and I just use that to crank out melting and boiling water when trying to pack light. I think it is a toss up whether to get one of these or not. I do like it when I have used it, I just wish they had a larger size option. The bigger the pot, the more liquid or snow needing to be efficiently heated.


      works great, have used it with a few different pots and seems to work better than without it. not sure how much faster or better it is, but it does work.

      great for helping to save fuel and speed boiling times

        i've used this on all my trips except for the most ultra light summer backpacking trips. it does a great job of heating teh sides of the pot, and saving valueable heat from escaping into the wild blue yonder. in cold temps, it aids boiling time, and i'm always boiled up faster than my buddies who don't use the exchanger. it's heavy, but can offset its own weight over long trips due to saved fuel. this is especially true in mountaineering/alpine trips where temps can be very cold. i'd give it 5 stars, but it is a bit heavy... sidenote, mine is litterally 16 years old, and looks brand new. well made and very durable.

        Gabe is right about the heat exchanger. I've had mine for years, and it heats meals faster and more evenly than without. One thing he didn't mention is that it really shines in windy conditions. I position the exchanger about 1 1/2 or 2 inches below the pot, and it catches the flame that is otherwise lost to the wind. I wish MSR would come out with a lighter version, though.

        Mine is also 15 years old and in perfect condition. Now that I have it, it's an essential part of my gear for any type of outdoor cooking. I like it for all the reasons Gabe and jnslop mention. MSR should make it a $25 dollar item.
