    I'm sure you'll find plenty of takers for your Taylors cooker!

    Q: Does "bio" ethanol give off a less unpleasant odour than Methylated spirit, or any odour at all? It's much much better!  Meths has nasty stuff added to deliberately taste and smell awful.  Bio ethanol doesn't.  If it has a smell, it's a little like brandy (I often referred to it as "distilled wine lake").  So it isn't quite odourless. You'd really need to try it - I have a recollection of some users complaining that even bio makes their eyes sting, so it's possible that you might not get in with it.  But I have no problems.

    Q Is an Origo stove second hand the best alcohol burner I'll get at the moment (I looked up Whitworths as mentioned earlier but no sign of a Maxie just now).  That I couldn't say.  I've heard well of the Maxie.  And Toplicht list an interesting looking ethanol stove: https://www.toplicht.de/en/shop/neu/neuigkeiten/spirituskocher-hpv but that seems to be out of stock.

    Q: How much slower is the Origo than propane?!  It is slower.  But acceptable (to me).   And not quite as controllable, but does simmer quite nicely.

    Q: Can we see the flame eg on a sunny day?  Not so easily.  And flames from any ethanol spills ditto.  Not a big problem, but something to be aware of.

    Q: If Origo is the one, do I have to make my own clamps to keep the pans on it?  I haven't tried their clamps.  Someone else will be along in a minute with some experience.

    I like my Origo running on bio.  In some ways, the ideal cooking setup would be a single burner Origo for general cooking, and a different stove that pumped out lots of heat for when you want to boil a lot of water in a hurry, or fry a steak - pressure ethanol?  pressure kero?

    Other opinions are available!

    Hi All,

    Some questions about changing from a Taylors pressurised paraffin stove to an alcohol stove..

    I have been working through this excellent series of posts in an attempt to educate myself on the subject of cooking stoves. However it spans 7 years, and I read very slowly...

    I've always used gas. Uneasily. Now we have a boat with a Taylors paraffin/kero stove. Very new and unused. But we all have a problem with the fumes. Meths for lighting, paraffin for cooking. It can't be good for us? And we sail in Scotland where we often have the fire on to keep us and the boat dry, so we don't want more ventilation than is necessary for that purpose.

    Since I doubt we can use anything other than paraffin on that pressure stove,I'm afraid I'm going to have to haul it out. Anyone interested in the stove please get in touch via my profile...

    Assuming for now that we'll try to avoid propane, may I ask a few questions?

    Does "bio" ethanol give off a less unpleasant odour than Methylated spirit, or any odour at all? Burnt and unburnt Meths is unpleasant to my crew.  I think the by products of the combustion of ethanol are pretty blameless compared to Meths. Is an Origo stove second hand the best alcohol burner I'll get at the moment (I looked up Whitworths as mentioned earlier but no sign of a Maxie just now). How much slower is the Origo than propane?! Can we see the flame eg on a sunny day?

    If Origo is the one, do I have to make my own clamps to keep the pans on it? There was mention that the fittings supplied aren't much good. The boat is a 34' Badger. Not planning on having gimbals as the cooker is athwartships and quite near the centreline. Coastal cruising at present. Any suggestions gratefully received!

    The new boat is Constance, built by John Greetham in SE England. I plan to bring her to the West coast of Scotland up the North Sea later this month. She will be on my profile as soon as I can.

    Jami, 

    my guess is that it has been cannibalised from some sort of equipment. The point is that the hot exhaust and the fanned air is separated. Only the metal gills are common contact surfaces. It should not be impossible to make for a metal sheet worker, professional or amateur.

    Arne,

    can you say what kind of heat exchanger is used in the video?

    Jami,

    That heater looked good, and suitable for live-aboard use. My ambitions are a bit more humble: I wanted to make a simple heater with max radiating power and minimum convection power (where hot air just rises to the ceiling). If I wanted an alcohol convection heater, I would just have bought the Origo Heat Pal 5100  -  or simply light up one of the Origo 3000 burners. That  would work well if an elephant trunk fan were added to circulate the heat. Adding a flue is for more serious use.

    I think my radiating heater works well now, but I will see if I can make a simpler version. My heater also started with an inverted steel bowl, but I found that without a lid on the bowl (insulated and with a hole in the middle for the flame), it would reflect so much heat back onto the stove that I was afraid that something expensive would happen.

    I’ll get back to this subject later  -  now I am busy on other fronts...

    A while ago I bought a new  Dometic Origo 1500 (single burner) to see if I could make a good heater of it. I used that one for my trials.

    Have you any results on your heater project? I have an Origo 3000 and I've bee fiddlling around with the idea of using one of the burners as a heater.

    This video has an idea. He uses a heat exchanger and a fan, and leads the burning gases outside. The removable system makes it possible to use the burner for cooking as well. I just don't understand what kind of a heat exchanger he is using and where to find one.

    To take the cone idea a little further:

    The original flame spreader has now become redundant. If the cone has a hole drilled through  it,near the top and horizontal, a thin rod can pass through and lodge in two grooves cut into the top of the cylindrical burner. Then it can be easily lifted out, using a little hook, for more convenient access for lighting.

    Good, Arne. This was the idea that I suggested here, and I'm glad that you've tried it out. 

    Ah, I had missed that one  -  great minds, etc...

    Anyway, I find that this cone is a lot better and practical than any of my earlier contraptions (..forced air of different kinds...), and it is the only version  I have made which appears to boost the burner. I am going to make two copies of it for my Origo 3000 on board Ingeborg.

    Now I have put more details on the diagram, so anyone, even without access to a printer, can make a paper pattern and then the real thing. The sheet of thin copper, which I had lying around, was easy to shape by hand.

    A minor sidestep: I have seen the new Origo One stove here; our dealer has both the 1500/3000 and the One/Two models. They seem identical when it comes burner and fuel canister. I chose the 1500 because it comes with a front rail, which takes the kettle holders (additional extras). These are easy to adjust, and hold any kettle or casserole very securely.
