Pots With Heat Exchangers

[Roger Caffin]

Any number of eBay vendors selling them for about $1 – empty. You can’t post full ones. Refill from standard lighter refill can.

Refill OUTSIDE: a messy business. Some butane always leaks.

Stove Net Weight: 360g

A bit heavy maybe?

[DAN-Y]

If I leave my ukelele at home I can justify the added weight :-)

Watch the video of the stove and envision all the snow you can melt with that inferno :-)

This photo is misleading:

[Jon Fong / Flat Cat Gear]

The stove itself weighs 360 grams:  BL100-B15

The pot weighs 305 grams: S2400 

Looks like an efficient flamethrower, from the video, it doesn’t look like it will simmer.  It does look pretty wind resistant as long as you are using the matching pot.  Not my cup of tea.

[Roger Caffin]

It’s a Reactor-style stove. They can be tolerable at full throttle, but turn them down to a reasonable level and they can be CO bombs. The Reactor emits lethal levels, and this one looks the same.

Cheers

[DAN-Y]

I actually posted this for snow melting folks out there in Alaska. I also thought it was interesting the cost of items coming out of Chinatown.  Thought David would be interested in sharing the info with his hunting buddies for Alaska adventures for 2 or more in a party. 1.5L is reasonable. I think he has one that size already. I’m tempted to purchase one just for the reactor type stove…can’t have too many stoves

[David Thomas]

Thanks. I haven’t played with a reactor style stove yet.  I do have the 1.5-liter pot already – it’s with me now.  I also got their 2.5 (+/-?) liter one recently and have been meaning to do speed and efficiency tests post and post the results. Right now, I’m outside of Denali. Breezy and 11F now. -2F forecast for dawn tomorrow.

[Roger Caffin]

Hi David

Very seriously: do not do the testing in any confined space. While 20 ppm CO was reasonable for the good stoves (some were even lower), and 100 ppm was imho a bit too high, the Reactor was hitting 2,000 ppm. At low power it neither sucks in enough oxygen, nor does it complete the combustion cycle. This new stove looks identical.

Cheers

[DAN-Y]

I like what I saw in the video, no fluctuation in flame output was visible. It’s interesting how the pot design worked out so well with the stove design that the pot could sit so low onto the stove to provide maximum wind resistance.

It looked as if the stove/pot boiled 4 cups in 4.5 min. Not too shabby.

[Jeff McWilliams]

Does it work with the canister in inverted, liquid feed mode?

[Roger Caffin]

Dunno.
IF it has a preheat tube somewhere, then yes. If it does not – tricky.
I would be reluctant to give an opinion without having one in my hand.

Having read all of the threads on HX pots I am thinking that skirted pots are the better solution and it seems nobody is making such at the moment.

Not so difficult but I am reluctant to hack up a new  pot to try the experiment with

Suffering has returned 

[Eric Blumensaadt]

Yeah BUT…, it’s Chinese. I just can’t bring myself to buy Chinese unless it is the only item of its kind.

Ex. I bought a Chinese made REI eVent parka & pants a few years ago B/C no US made items were available at the time (within reason, that is).

No. it’s not racial, I’m married to a Filipina, it’s the lack of Chinese quality control and the Chinese government treatment of Tibetans and the S.China Sea island building/maritime takeover. Way too arrogant of a dominating Han culture thing for me. As a former Peace Corps Volunteer (Philippines) I’m a bit more culturally sensitive than most regarding Chinese expansionism. Jus’ sayin’…

[Adam Kilpatrick]

This is a great thread, thanks all involved! I’ve learnt so much reading through it this evening :-)

Looks like “Bulin” makes a reasonable variety of HE and non-HE pots. And kettles! Some variations in both, so the added weight (at least going by their listed weights) can sometimes be compared. Eg the kettles here:

 

https://www.ebay.com.au/itm/0-8-1-5L-Camping-Heat-Exchanger-Water-Kettle-Tea-Pot-Energy-gathering-Coffee-Pot/253114118803?hash=item3aeec6f293:m:mGyhzH_bC7ZibEURhbd209g:rk:43:pf:0

 

Ie 60g addition to 1.2L, 72g 1.5L

…kettles with same listed diameter…something is fishy haha).

 

I can see myself taking a cheap HE pot with canister stove on future trips to Japan with my significant other… efficiency/weight aside, the speed bonus may sometimes be worth it. She gets cold incredibly easily and doesn’t have the same experience I do…gotta look after her and keep her happy. Having said that, just sticking an extra 2-3 oz of down on her (say in a jacket) probably makes more of a difference than waiting a few extra minutes for that first cuppa once out of the rain (or in the morning).

 

I really like Jerry’s Al+steel wire solution too. The weight isn’t too bad for the benefit.

Thanks again!

 

[Adam Kilpatrick]

Hmmm. Though I’m just remembering (how could I forget) that the only thing that irritates me more dealing with a stove at the end of the day than esbit smell/funk, is fiddling with foil-esque windscreens. Maybe a HE pot really is for me…

[Roger Caffin]

The extra weight of 60 – 70 g is not bad – better by far than the seriously heavy Jetboil pots for instance.

The handles are actually stainless steel I think, and rather heavy. I removed the SS handle on one of these and replaced it with some Ti wire, for a significant weight saving. I put some heatshrink on the wire for safety.

Cheers

Do what I did?

Get a jetboil ( I was given an old PCS)

Get rid of the underpowered burner,

Keep the pan and cut slots in the skirt to accept the soto windmaster 4 way potstand.

This setup is more windproof than the jetboil, nearly 100g lighter and near 2 mins faster to boil a pint on the same amount of gas.  What’s not to like?

I use it for work several times a week. Day walks and occasionally backpacking. (Prefer alcohol/Esbit and a cone usually)

[DAN-Y]

Lots of interesting info in this thread, don’t let it go to the wayside.

[DAN-Y]

Bump for renewed interest. Any new designs found  since last posting?

Gotta like this design of burner Might hack one up for my modified milk pot project :-)

[DAN-Y]

HX pot with HX Skirt weighs 5 ounces/145 grams

[Roger Caffin]

Dan – are you sure about that 145 g?
The Bulin web site says 305 g on the page for S2400.
Did you take the handle and the lid off for this weight?
I imagine the handle is steel and therefor massively heavy. What does the lid weigh?
Could be interesting though.

Cheers

[DAN-Y]

Roger, it’s not a Bulin pot. I weighed it again this morning, it gained weight, 147 grams.

With the lid, 154 grams.

Volume of pot is one Australian serving of morning coffee…500ml :-)

Boil times are averaging 2.5 min I have not measured how much fuel is being used. I’ll be doing more tests this week. The most important/often question asked about canister stoves is….How fast can it boil? ;)

Titanium skirt fits easily inside pot.
