• Butane vs Propane in cold temps

    How cold will a butane gas bottle (calor 4.5 Kg) work till?

    I.e, if it is outside at say -4C, will gas still flow to the appliance?

    (Propane seems to be the lpg fuel of choice for gig shower blocks, etc. Is thot because it works at lower temps? Or maybe you get more bang for your buck?)

    Butane fails to vapourise around 0 C from memory.

    Propane will still vapourise, again from memory, below -30 C.

    Most things like heaters, cooking appliances, use vapour.

    I believe fork lifts use liquid propane - you may notice the cylinders are usually horizontal. Cylinders in vapour systems - at least the smaller
    ones- are used vertically so there is a volume for the vapour to collect to
    be drawn off.


    In France, it is common for people to use butane in houses to run kitchen
    hobs, certainly in semi rural / rural areas. That is why you see so many supermarkets selling refills.

    They also sell butane for outdoor use - caravans, motorhomes etc.

    In terms of energy output, butane is higher. However, this is offset by the vapourisation issue.

    How expensive are butane and propane in cylinders in France compared
    with here?

    My parents have a holiday cottage which has no mains gas supply to the village, and they chose bottled propane (2x 47 kg cylinders) for central heating. It is hideously expensive to run compared with oil. When we
    lived there for a year, a pair of cylinders only lasted a week or so in winter.

    I suppose if one uses oil for central heating and hot water, and only
    uses bottled gas where oil is not a substitute (eg a gas cooker) then
    the cost is less.

    No, From memory of caravanning around 60 years ago ,and conversations on Spanish Facebook groups it starts to fail around +4C. Whilst the boiling
    point is lower the problem is that as the liquid gas vaporises it cools
    due to the fact it is the higher energy molecules that escape as gas,
    leaving lower energy molecules in the cylinder, so the temperature is
    lower. So if the air temp is +4, whilst the butane starts at +4 it cools
    until it stops working.



    (Propane seems to be the lpg fuel of choice for gig shower blocks, etc. Is thot because it works at lower temps? Or maybe you get more bang for your buck?)


    It works down to much lower temperatures. I think the "calories per kg"
    is a little higher for butane, but I may be wrong.

    In this sentence, you can see what makes the butane work
    at low ambient.

    "i've ran my jetboil at 10 degrees I held the canister
    in my hands to keep it chugging worked pretty well...
    out of curiosity i set it down and the flame died rapidly"

    The heat from his hand, was helping to boil the butane
    and provide vapour for the job.

    As the ambient gets lower and lower, the heat loss from
    the tank surface, exceeds the heat input from a hand
    laid onto the cylinder. Sticking a hand on the side of the
    tank, to maintain a vapour flow, is only going to work
    at moderately cold temperatures. It wouldn't work
    in Antarctic winter, to use your hand.

    You sometimes see reference to these, in arctic adventure stories.

    A lot depends on how quickly you want it. For most practical purposes for
    a caravan or motorhome cooking/heating the off-gassing diminishes greatly
    as you near 4-#C.

    We made the mistake of using butane in our caravan many years ago early in
    the spring and had to bring the bottle into the van and heat with with a
    hair dryer (fortunately we had some mains power) to get it to work.

    Butane has a higher calorific value and the cylinders are cheaper in terms
    of -u/kg of gas so you do get more rCLbangs for your buckrCY but werCOve had issues with newer van appliances running poorly on butane compared to
    propane so werCOve just ceased buying it.

    Butane becomes difficult, when in temperatures below around 5C. There is
    no precise temperature, because it's usuability, depends on the internal temperature of the gas. It might be 5C ambient, but making use of the
    gas, evaporation, cools the contents down, and can cool it below the
    point of it being able to evaporate. To evaporate the gas, from the
    liquid state, it need to draw heat from outside the bottle.

    So what can happen is you begin using it just fine at 5C, then the
    pressure simply dives.

    Propane, is the stuff to use year round. Notice the frost appearing on
    the red bottles, when the contents is being used - it shows the liquid
    level.

    The cheapest way to buy gas, is in a bulk delivery, into a fixed tank,

    powered vehicles, to a refillable container such as Gaslow. Last I
    heard, around 54p per litre.

    They used to supply two different setting of pressure for the two gases,
    but now they have compromised on a pressure between the two. Modern
    caravan appliances seem to perform just fine on the compromise pressure.

    I buy propane year round, for the caravan, so it is guaranteed to work
    in the cold mornings of early spring and late autumn.

    The classic trick is to take a butane cylinder and set it on the steadily diminishing flame of the butane burner.

    Or take the big propane torch, blowing out many pounds of propane an hour, and fire it at the cylinder to heat it, with the propane level clearly visible as a layer of water ice on the outside of the bottle.

    What could *possibly* go wrong?

    with here?

    Last time we bought a fill up*, the difference on 6kg was probably about
    -u5.


    * We had a motorhome at the time which had space for 2 cylinders. In
    Europe, I used to carry a UK one and a French Le Cube. The latter was only
    used one trips to Europe, so tended to last a two seasons at least. We now have one with a refillable tank. Even here, that is FAR cheaper. Our tank
    holds 20 litre*, near enough 10 kg. Last time I topped it up - a couple of weeks back locally- it cost 99p / litre. Say -u20 to fill it. Last time I bought a 6kg Calor refill, it was about -u32.

    My parents have a holiday cottage which has no mains gas supply to the village, and they chose bottled propane (2x 47 kg cylinders) for central heating. It is hideously expensive to run compared with oil. When we

    You can get legally refillable cylinders but they tend to be smaller. I
    think 11 kg is the largest.
    You refill them at Garages selling LPG for cars. The cylinders arenrCOt
    cheap but, if you use a lot of gas, you can recover the cost.



    We first encountered French gas cylinders when we used to rent Gites. They usually had cylinders which were about 15kg size, in some cases tucked
    under the bench. I then bought a Le Cube when we started touring France etc
    in our Motorhome.


    * it is a 25 litre tank but they have a valve limiting to contents to 80%.

    The rCyportablerCO cylinders do but you can have a large, fixed tank installed.
    It is this kind of fixed tank Harry means.

    These fixed tanks are more akin to the large oil tanks people have for oil heating systems. You sometimes see them in the country.

    The Gaslow type do, as you say, top out at 11kg.

    Our MH has a fixed tank which holds 20 litres, 10kg near enough. I topped
    it up a couple of weeks back at Morrisons 99p / litre.

    In France a 13Kg propane or butane cylinder costs about the same as

    Thank you, your numbers are probably more up to date. It is a while since I bought a refill in France.

    As an aside, I am amazed by the availability of cylinders and the number of brands in France.

    When I first got a diesel car in 1986 I took a sample of the fuel and
    put it into the freezer for severla days, which was I suppose at -15 to
    -20C. It went milky white but still slopped around easily. I assumed
    that was because flakes of solid were forming within the liquid. So the
    fuel would flow, but might block filters or pumps. The car mitigated
    that by having an in-line electric fuel heater before anything critical.

    How cold does it have to get before you need to heat the bulk fuel and
    not the lines? Or was modern DERV different even back in 1986? Shortly
    after I got that car, filling stations started to advertise that they
    were selling "winter diesel".

    They used to supply two different setting of pressure for the two gases,

    We had a motorhome fridge soot up to the point of non-functioning after a relatively short period on butane.

    Butane fails to vapourise around 0 C from memory.

    Propane will still vapourise, again from memory, below -30 C.

    Most things like heaters, cooking appliances, use vapour.

    I believe fork lifts use liquid propane - you may notice the cylinders are usually horizontal. Cylinders in vapour systems - at least the smaller
    ones- are used vertically so there is a volume for the vapour to collect to be drawn off.


    In France, it is common for people to use butane in houses to run kitchen hobs, certainly in semi rural / rural areas. That is why you see so many supermarkets selling refills.

    They also sell butane for outdoor use - caravans, motorhomes etc.

    In terms of energy output, butane is higher. However, this is offset by the vapourisation issue.

    I always use propane in the caravan to avoid problems on cold mornings,
    but when I needed some new (non-refillable) canisters for use with a
    garden 'Flame Wand', I bought butane because a) They were a bit cheaper
    and b) I was going to be using them in the middle of a hot summer - so
    who cares about low temperature performance?

    I wuz wrong.
    Even in ambient temperatures over 20C, the flame would gradually reduce
    until after maybe 10-12 minutes use the thing was useless even at
    maximum setting.
    I ended up using two canisters & swapping between them at frequent

    The blending recipe that refineries use, is changed on a
    weekly basis, based on weather forecasts and existing
    conditions. You make 25C fuel, consumed on a 25C day.
    You do not make -40C fuel, and serve it on +30C day.
    The temperature and the blend, are hand-in-glove items.
    It is custom blending, for absolutely the best running
    conditions possible.

    The oil companies and this business, are one strange beast
    from end to end.

    Ask yourself this. The word "tariff" and "gasoline" do not
    appear in the same sentence. Do you know what a riot looks
    like ? That's what would happen if "tariff" and "gasoline"
    appear in the same sentence in print :-/ The oil industry
    is so fragile, so "teetering on the edge", you don't
    dare touch it for fear of breaking it. We can close
    old, worn out refineries. Yet, we cannot build new ones.
    It's become like some law of physics, building a new
    refinery is like traveling faster than the speed of light.
    If *two* refineries close for maintenance on the same week now,
    the price of diesel *doubles*. That is what I mean by
    teetering. It hangs by a thread. You cannot fuck with it,
    you cannot change any blend recipes. You can't even
    fart near a refinery.

    Did I mention your vehicle should be "multi-fuel ready" ?
    well, it should be. Do what you can, to identify two fuels
    that your vehicle can burn in an emergency.

    Butane boils at 0 -#C & propane at minus 42 -#C.



    You can watch propane boil here, at 4 minutes into the video or so.
    This shows the available heat at room temperature, ready and able
    to boil the liquid.

    "Boiling Propane with Doug Reid"

    https://www.youtube.com/watch?v=94dCGHSoTXM

    This is liquid propane in a beaker, outdoors in winter, in the Yukon.
    They apply a source of heat, and the liquid doesn't even have a chance
    to reach an equilibrium, giving the impression boiling happens at
    a temperature below the textbook value. Notice he didn't use hand
    warmth to bring it to a boil.

    https://www.youtube.com/watch?v=9wbX9tN7Y9Y

    Notice as well, his "ignition demo" at the end of the video, is
    less than spectacular, due to the low ambient temperature. If
    you splashed liquid propane around at 25C, and there was a flame nearby,
    you'd be over in the bleachers somewhere by now :-) The ignition at -40, reminds you of a small quantity of petrol at room temperature.

    Winterised diesel has an additive that keeps it dissolved

    I remember in the days before winterised diesel a popular suggestion
    doing the rounds was to put a gallon of petrol in the tank then fill
    the tank with diesel, and that was supposed to prevent waxing.

    I didn't know anyone using diesel in those days so I don't know if it
    worked or not.


    It was popular enough to be in the manual for my Citroen BX17RD (2* at
    about 1 to 10 ratio)! I never tried it, I used to buy diesel additive in
    a small tin and dose after each fill. Stopped when they started claiming
    to sell winter diesel.

    Ive been driving pretty much all diesel for around 13 years. No problems
    on icy morning starts except its a little rougher till it warms up
    Additives + glow plugs make light work

    It becomes a vicious cycle.

    I like my fish from the cabinet when the batter has had a chance to go a
    bit soggy. This means the fish needs to have been cooked in advance and
    left in the cabinet.

    "Back in the day" this was no problem. And they stack the cabinet as the
    queue moved so you nearly always got a nice steamy batter fish.

    Then the price went up, the queues slowed and no one will cook fish
    unless it's ordered. Meaning it is now "nice'n'fresh" and totally not
    what I wanted.

    I've not had fish from a chippy since before 2020 and lockdown.

    On the odd occasion I use a chippy it's either a fishcake, roe or kebab

    It needs to be vaporised to go remotely 'bang' in air. ANFO has the

    The other big advantage of cook-in-advance is that it will have cooled

    I've had diesel cars since the mid 90s (Peugeot 306 with 1.9 non-HDi
    engine, Peugeot 306 2.0 HDi and Peugeot 308 1.6 HDi, and my wife's two
    cars - Honda Civic and Honda CR-V were/are diesel).

    I've never had problems with starting or running when cold. The only
    problem is that when the oil is very viscous, the starter motor has
    trouble turning the engine to get it up to firing speed - but the actual ignition of the fuel and the running when very cold is faultless. Much
    better than the petrol-engined cars that I had which suffered
    engine-fade as I tried to accelerate, if the engine was very cold.

    The Honda Civic used to give out a lot of blue/white cold-diesel smoke
    when it was very cold weather for the first few minutes. It was
    definitely incomplete combustion of diesel, and not the very different
    smell of engine oil burning.

    As far as I know (I've not driven behind my Peugeot to see its exhaust)
    it still has clean (non-sooty) exhaust during acceleration, after 17
    years and 200,000 miles and it still goes very well - good acceleration
    when needed, fuel economy almost as good as when it was new. The only
    problem is a bit of hesitance and flat-spot at about 25-30 mph around
    town, if I approach a slight bend, or ease off the power for a moment,
    and then accelerate (gently) out of it. Still a bloody good car.

    Some years ago it needed a new diesel particulate filter and catalytic converter which cost -u1000 in total. Ouch! Given its age, I'd have got
    next to nothing if I'd sold it to the garage without those fixes, so I
    bit the bullet and kept it. I'm glad I did.

    The next big bills will be new cam-belt once that becomes due, and at
    some point it will need a new clutch since the bite point started to
    rise about 10,000 miles ago (up until then, the auto-adjustment
    compensated for gradual wear). But there is no sign of clutch slipping
    at all: it will still do a hill-start on a 1:3 hill (Rosedale Chimney,
    near me *). And it's not done badly: 200,000 miles on its original
    clutch - unless it was changed (highly unlikely!) in the first 18,000
    before I bought the car as an ex-demonstrator.


    (*) When the car in front of me ground to a halt, I had no option but to
    stop as well. The driver ahead of me panicked and kept rolling further
    and further back, eventually using up the very generous gap that I
    always leave when going up there, so I had to get out and drive his car
    to the top (**) and then go back for my car!

    (**) I stalled the first time - unknown engine, unknown clutch bite
    point - but I didn't roll back an inch because I know how to hold a car
    on the handbrake until the engine starts to pull the car uphill, unlike
    the guy whose car it was. Being a petrol engine, it needed a *lot* of
    throttle to pull the car, unlike my diesel which pulled away at about
    1200 rpm, so only a little bit above idling.

    Notice as well, his "ignition demo" at the end of the video, is less

    over in the bleachers somewhere by now :-) The ignition at -40,
    reminds you of a small quantity of petrol at room temperature.

    I remember in my first job when we had a fire safety demo, seeing the difference between the flammability of petrol and diesel. On a hot sunny day, the lecturer laid out two shallow metal trays on the grass, each
    about 1 cm deep and about 1 metre square. He applied a flaming rag on
    the end of a pole to each.

    The one containing petrol ignited before the rag even touched the
    surface, so it was the vapour which lit first and then ignited the
    liquid. No surprise there.

    However the one containing diesel refused to ignite. There was no significant amount of vapour, even though the diesel had been standing
    at about 30 deg C for a few hours, and when the rag touched the liquid
    it went out. The only way he could get the diesel to light was to bubble nitrogen (chosen to be relatively inert compared with oxygen or
    atmospheric air) through it, to create small droplets - but even though those burned, they didn't ignite the pool of diesel for a long time. One
    it was alight, it burned very fiercely with filthy black smoke.
    Likewise, a perfume atomiser of diesel produced a very impressive "flamethrower" jet because the atomiser acted like a fuel injector and produced a mist of droplets which could be ignited by the burning rag.

    Isn't diesel used in ANFO ?

    Yes but the AN is what supplies the oxygen.

    almost like it is biological activity on a wet surface.

    The weird part of the picture, is this size always appear in pairs :-)
    As if, maybe, it has something to do with the tank filling
    ritual. Like, run off one cylinder, while the truck fills the

    this, to ask about the pair thing. Maybe at low temperature, you
    can "freeze out" one cylinder, and switch over to the other for
    a while.

    The next size up, is a horizontal tank, there is only the one tank,
    it might be equal to three or four of those tanks, and that is used
    on a farm, where perhaps some of the farm equipment runs off propane too.
    It would be a truck fill.

    The farm one is 1000 gallon. According to this page.

    https://www.superiorpropane.com/tank-sizes

    "Larger Propane Tanks

    If you have a large commercial operation and need a greater
    supply of propane, we have tanks ranging from 2,000 to 60,000 gallons.
    "

    I don't think propane is particularly cheap. And if the delivery
    truck doesn't show up (unreliable distribution scheme), that
    can be a stressor. We've had rail strikes, where they had to get
    creative to keep the propane tanks filled. It's OK if your
    propane is "mostly decorative" and you don't have a daily
    consumption pattern.

    And be careful with those little barbeque tanks, and the positioning
    of your barbeque with respect to the house. A neighbour four doors down,
    their outdppr barbeque lit the side of the house on fire. Two fire vehicles showed up, a pumper and a ladder truck. The ladder truck, the boom was maintained horizontal, and swung in near the property, and the firemen
    used an aerial attack on the fire (run along boom, carrying hose).
    As it would be harder to run a hose all way round the house and fight
    the fire from ground level.

    Nothing weird about that. In the UK you would have an automatic changeover valve that switches the supply when one tank empties. This would be on swappable tanks rather than ones that are refilled in situ but the same principle of maintaining a constant supply would apply.

    I've caught & skinned plenty of those ie dogfish or huss. Gloves &
    pliers recommended.
    Not quite as bad as skinning skate wings though.

    I leave fish prep to the experts. Even if I could source a filleting
    knife with ease.

    Oh its not hard to fillet a sardine or a mackerel, or a trout. Or cut
    steaks out of a Tuna fish!

    It's herrings I draw the line at.

    I can't recall if it was a dover or a lemon sole, but once was enough.

    Of course trying to find a fishmonger is now as much a challenge as
    finding a butcher.

    IIRC our local Tescos has a good one.

    several butchers in this area.

    we have a butcher in our village - but the fishmonger vanished at lest 30
    years ago. However, Waitrose have a decent fish counter.

    You obviously haven't visited for a while. Tesco closed all its fish
    counters in 2023. My Sainsbury's no longer has one either.


    several butchers in this area.


    My favourite butchers seems to be vanishing quicker than pubs. The one
    in my local Sainsbury's is no more as it also closed its butchery
    counter, our nearest Booths which had a great meat selection is now an
    Asda. My two "go to" independent butchers have also gone.

    Move up to Aberdeenshire - we have both in this village. More butchers
    in the villages east and west of us and a fresh fish van does the rounds weekly, from Peterhead I think.

    Swings and roundabouts though. We have an excellent doctor's practice
    and chemist in the village, but nearest hospital is 40+ miles away.

    Local Co-op serves us well, but nearest large supermarket is 25 miles
    with more choice 40 miles away.

    Had a wonderful old fashioned ironmonger, but he has just retired, at
    80. Nearest 25 miles away with 'sheds' 40 miles away.

    We do have a baker though :-)

    How cold will a butane gas bottle (calor 4.5 Kg) work till?

    I.e, if it is outside at say -4C, will gas still flow to the appliance?

    (Propane seems to be the lpg fuel of choice for gig shower blocks, etc. Is thot because it works at lower temps? Or maybe you get more bang for your buck?)

    Propane is the gas of choice if you want to be able to use it at any
    time of year, not just warmer months.

    But even at low temperatures propane produces less heat due to reduced pressure. For flying in the Alps hot-air balloon propane tanks are
    'spiked' with nitrogen in order to increase the pressure. However, you
    need to burn all the propane in the tank before the ambient temperature
    rises because the pressure will then increase further. The nitrogen
    doesn't sit on top of the propane it mixes into it so you need to get
    rid of all the propane.
