DIY canister stove windscreen

Looks good. I imagine a similar setup would work well to replace the factory screen on my snow peak gigapower.

But in cold weather you don't WANT to protect the canister from the warmth from the flames. You NEED the heat input to keep it going.

Unless you apply the heat in a controlled fashion, the effect on the cannister is inconsistent at best.

Ambient airflow is almost always an issue with any stove efficiency in an season. Cold airtemps are not. And a good windscreen acts not only as a wind deflector but as a reflective heat shield. Unless a design is too heavy,it always increases a stove's efficiency even in calm conditions.

Eric's bottom screen protects the pot from being robbed of heat by updraft around the pot sides. This is a net plus for most folks using an upright cannister stove.

For cold weather use, the ultimate setup might be a combination of Eric's rig above with a slot cut in the base for the insertion of Bob Moulder's heat exchange strip.

The everyone is happy. Even in cold weather.

Then,we can discuss more weighty issues like- can you cook with it inside your tent with out burning it down or dying of Carbon Monoxide poisoning ?..:)

Jimmer,

What is Bob Moulder's heat exchanger strip? Sounds interesting for cold weather canister cooking. (However I do have the new MSR Whisperlite Universal with the "upside-down" canister support thingy for cold weather. Heavier but effective.)

Is there a photo of Bob's heat exchanger strip on this site or elsewhere?

Eric, if you read the first and last page of this thread you'll have all the necessary information:

I have tested this a bunch and it obliterates the cold-weather canister conundrum.

Thanks Eric, I was trying to rig up some short pieces of wire, too fiddly. Your setup holds the windscreen up, not too much a concern for me to protect the canister though.

Your mileage may vary. I have no trouble getting a consistent warming of the canister.

I simply disagree.
In my experience the amount of heat lost through a small amount of air going past the canister is only a fraction of the amount of heat to be gained from radiation.

For really cold weather I use an inverted canister stove, which solves all problems.

Roger,

I bought the MSR Whisperlite Universal so I could have both a petrol stove and an inverted canister stove. It's my winter stove "system".

So I now have this new canister stove, an MSR Simmerlite and a Brunton hose connector to convert my Brunton Crux into a remote canister stove. So that makes three remote canister stoves in my gear closet. Guess I should sell the Simmerlite. The other two will be good for car camping.

BTW, The Brunton/Crux stove in the photos is for 3 season use.

Hi Eric

As you doubtless know, I am a fan of remote canister stoves. :-) I often use mine in the shoulder seasons as well, just because it is so light.

For summer use – I have never used a reflector above the canister in the last 10+ years. Never any problems. But I DO use a 3/4 wrap windscreen ALL the time.

Cheers

Awesome, just copied this in 5 minutes with a cake pan I had laying around. Thanks! I never actually use my microrocket anymore but it's still nice to have a better windscreen for it.
