An engineered cooking accessory for improving fuel economy while melting snow or boiling water on longer trips. Not recommended for delicate cooking or simmering, since any spillage will be difficult to clean out of the unit.

Increase the efficiency of your stove up to 25% with the MSR Heat Exchanger. The 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).

MSR’s Heat Exchanger increases the efficiency of your stoves up to 25%. The unique waffled design channels the heat from the stove up the sides of the pot to increase the heated surface area of the pot. The Heat Exchanger is compatible with all MSR 1.5- and 2-liter pots. (with the exception of the Titan 1.5-liter)

The heat exchanger increases efficiency up to 25% by wrapping around a cook pot to capture heat normally lost to the atmosphere.

This corrugated metal windscreen wraps around your cookpot and funnels heat up the sides for faster, more even heating.
The MSR Heat Exchanger decreases boiling time significantly by capturing lost heat and redirecting it back into the cook pot.

Saves Fuel | |
| Rating: | ![]() |
| Tested 6 stoves/fuels, side by each at ambient temp of 20 degrees. Water was at 40 degrees. Matching MSR pans cooled in snow three minutes between tests. regardless of stove selected, cover and heat exchanger made difference. On the Whisperlite Internationale, for example: An uncovered pot took 6 minutes and thirty seconds to boil; adding a tight lid dropped the boiling time by a minute and a half; fitting it with the heat exchanger and cover reduced the boiling time to just four minutes. The MSR heat exchanger was advertised at 7 oz; ours weighed in at 5.2. Saves 2 oz fuel per pint at 20 degrees. Troop 6 did the test, you do your math. We'll take one every trip. | |

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. | |

| Works great. Got mine with my Alpine cookset, well worth the money. Only problem: it takes up the space in my cookset that I use for my stove or MSR Kitchen Cupboard. I take it for cold weather or high altitude, and for my 2 week survival trip every other year. It really cuts down on the fuel usage. | |

"boil faster = save fuel" | |

| i bought a while back and really have no use for it. i can see how it really drops the boil time but i have really never been out when it was cold enough to need it. oh well, its gold and msr makes it so buy it you cheap son of a bitch. | |

| Works really well. Shortens cooking time which saves fuel. Durable construction. worth the weight and space it takes up. | |
