Here you can see some of the design elements of the PNWR#2. Though I was very happy with the PNWR#1, the PNWR#2 features a number of changes from the PNWR#1.
Improvements over the PNWR#1:
1. This stove uses the base of a disposable propane tank for it's backbone and most of the combustion chamber instead of a thin iron can, which makes it much more durable, though an iron can is still used just above the combustion chamber. The design allows the use of a stainless steel water bottle instead of the iron can, but would sacrifice my precious water bottle.
2. An enhanced heat shield packed with fiberglass insulation has been added to increase efficiency and reduce burn hazard. This makes the stove a lot easier to use and safer to handle, as well as more efficient.
3. The draft tube is removable to allow easier packing and loading before lighting.
4. The bottom is closed except for air vents in front of the combustion area. This causes additional coals to line the bottom of the stove, which allows it to idle longer after cooking and be ready to cook another meal or after dinner drinks. Excessive ash can still be cleared via the air vents if needed.
5. The front air vent shield has been expanded for greater efficiency and safety.
6. The hopper has been relaxed to allow fuel rods to be inserted either vertically or with as much as a 30 degree angle. This keeps dry wood in the hopper from overheating before reaching the combustion chamber and allows sticks longer than the height of the stove to be used if desired since these now clear the cook pan. For wet wood, keeping the fuel rods vertical provides greater heating and drying prior to combustion. In addition, aluminum foil can be wrapped around the fuel hopper to further increase heat retention if desired.
7. The two heat shields are very solid and increase the stability and footprint of the stove making it less likely to be knocked over when cooking.
Drawbacks:
1. Total weight is 314 Grams, which is still lightweight, but heavier than the PNWR#1. My Whisperlite excluding fuel or tank weighs 318 grams. Including fuel and fuel tank, the Whisperlite weighs over twice the PNWR#2.
2. The combustion chamber is slightly smaller, which equates to slightly lower output power. This proved to be a problem with wet wood as it didn't obtain the critical mass to power through.
3. Because only part of the bottom is open, it is not as easy to light as the PNWR#1. This is a tradeoff which reduces ease of lighting and ease of clearing the combustion chamber, but increases efficiency, idle time, and containment of hot coals.
