I don't know if this link has been mentioned or if will be of any use.  It's been helpful for me since I use kerosene for cooking and heating on Sea Elf.  https://classiccampstoves.com/

PS: A single-burner 2kW Origo 1500, plus a single-burner Hpv-salsa seem to me to be a good combination for a serious cook.

After all, my boil-test showed that the Origo cooked 1/2 litre in 4:39min while the Optimus 111 did it in 3:45min after preheating. David reported on 20.9 that his Maxie burner took 5m 48s  to boil the same amount. 

Arne, I'm not sure you're comparing apples to apples.  When I did a head to head with the Maxie and the Origo using the same pot/fuel/water volume/temperature, the Maxie is more efficient in fuel use and also faster.  However, the Origo is not so far behind, it still is a very useful stove.

“At the Stores I asked for a No. 3 Rippingille stove, and was confronted with a formidable and hideous piece of ironmongery, which burned petroleum in two capacious tanks, horribly prophetic of a smell of warm oil. I paid for this miserably, convinced of its grim efficiency, but speculating as to the domestic conditions which caused it to be sent for as an afterthought by telegram.”

Excerpt from Erskine Childers: “The Riddle of the Sands.”

Konstantin Stanislavski the Russian theatre dare I say 'guru' called it Sense Memory.  Those actors who have been trained in 'the method' and derive their skillset from the  teachings of the Actors Studio, Harold Clurman and Stella Adler use these triggers to regenerate a truthful feeling. As do some who don't! Using music of a relevent kind is a   useful technique.

File under 'useless info', David. 

I have checked up the multi-fuel burners. Most of them are of the loud type, and they don’t have an internal cleaning needle. However, some are with silent burners, and could probably be built into an old stove, like the Optimus 155, if needed. Their output seems to be very high, up to 3kW.

However, by searching on “Petroleum Kocher” (kerosene stove), a few German sites pop up. One even sells brand new Optimus 155 and spares. One, like the Topplicht site, operate in English for those who don’t read German.

I guess, for serious cooking, one 2.5kW kero burner, plus one Origo 1500 single burner stove is ideal. The last one’s ability to set on simmer heat (and then with a perfectly blue flame) is very useful.

Btw, during browsing the www, I came over a discussion about kerosene and smell. One fellow stated that by adding 5% denaturized alcohol to the kerosene, the kerosene lamps just about stopped producing any smell.

 PS: Yesterday I came over this Swedish site on Kerosene stoves. It is a Facebook site, so maybe one must be on Facebook to make it work. Hopefully the translator makes it understandable.
