Which gas bottle

[Garyandlou]

Hi
Sorry for the daft question but I've seen both used. Do you use the blue bottle or the red one in the campervan or does it not matter

 

[glenn2926]

Use the red one it’s propane. The blue is butane. Red burns hotter and still works in cold weather whereas the blue stays as liquid when cold.

 

[JohnJan]

The blue one, butane, freezes at a higher temperature than the red one, propane. Most people use propane. Personal choice, it's up to you.

He had faster fingers above!

I’d suggest Propane (orange) rather than Butane (blue) as it has a better tolerance to cold temperatures if your planning on using it in the winter, especially in the U.K.

Doh.....only third

 

[DandG5515]

Hi blue is butane and red is propane, both will run the appliances, however butane can freeze, lpg is a mix of both. The bottles have different connections so need hoses changed to switch all the best Graham

No. Butane has a higher calorific value and burns hotter. But propane has a lower evaporating temperature so can be used year round.

It's a bit like comparing petrol (propane) and diesel (butane)

Propane produces 96 Megajoules of energy per cubic metre.

Butane 126 Megajoules of energy per cubic metre – far more than either natural gas or propane.

the last staement in that has got reversed probably from a caravan magazine,if you check the tables in link propane has the lower caloric value

Fuels - Higher and Lower Calorific Values

Higher and lower calorific values (heating values) for fuels like coke, oil, wood, hydrogen and others.

The only thing I’ve found is. The kettle boils quicker on propane than butane. Which is all that really matters.

I’ve just posted the calorific values.....

Obviously the increased propane pressure compensates a little towards the impression that it’s hotter.

I think that is the main answer....especially in winter.

By the way.....theres no such thing as a daft question, it would be daft not to ask if you don’t know the answer.

Except that 'Vans manufactured after 2002? have a fixed Regulator that reduces the pressure coming out of the bottle to the same, regardless of whether it's Butane or Propane.

As someone has said the only daft question is the one you didn’t ask

 

[David and Sally]

Propane. Always. Does not freeze. Who cares if it heats a kettle 0.01 seconds after butane?
Not a daft question. It is always good for a debate.

 

[TheBig1]

As some on here will testify, we used to struggle in spring or autumn when the temperature dropped and we only had butane. Especially the exposed bottles on old caravan draw bars, before integrated gas lockers were common. You would often have to heat some water and pour the hot water on the gas cylinder to get it warmed up so it would produce gas. Then put an insulated cover made from an old coat on the cylinder to keep it warm

I can see by your avatar that you got the Ro flag. Are you in Ro?

Beat me I was going to mention that to add a bit of info.
From 2002 both run at 30mb, previously UK ran butane at 28mb & propane at 37mb but Germany and some other countries ran propane at 50mb.

Another thing if you have a Truma Combi even when the weather is not that cold butane often can't supply the flow rate needed for a Combi.

 

[TUCANO]

Propane is Perfect.
Butane is a Bugger.

Only virtually Raul, I use a VPN and actually chose a server in Canada, but it routed me via Romania. Still a fast connection though. May show as china or Mongolia tomorrow

 

[Raul]

Maybe something to do with speed available. I have cable in rural Ro and under 80 meg speed is rare. Some towns are already on 1-2 terra. In London I struggled to get 16-20 meg with BT fibre.

 

[MisterB]

back to the debate .....

what some people forget is that pressure in a vessel depends on the altitude - so if you're taller than someone else, butane AND propane will both produce worse results as you are at a higher altitude than someone shorter then you. the kettle will take longer to boil and food longer to cook (or in our case, that could be defined as heating stuff up ....)

its for that reason that my wife is encouraged to make hot drinks and sometimes even 'cook' .......

of course i tend to do the bbq'ing as the bbq is always at ground level .......

Pressure in the vessel is directly related to outside temperature. There is a chart with pressure/ temperature. Also as it travels from the vessel, it absorbs the surrounding temperature. Hence when you have a high discharge, the vessel tends to ice up, up to the regulator. Apart from the fact that propane boils down to -37-40 deg C compared to butane, only down to -2degC, butane, has one extra molecule of CH, carbon hidrogen, witch translates into a higher calorific value per unit.

[Richard n Ann]

The temperature of a liquid is defined as being it's mean temperature. The warmer the molecules the more they jiggle about. The warmest molecules are at the surface of the liquid and the most jiggly ones break free (evaporate) thus lowering the mean temperature of the remaining liquid.

 

[SpeedyDux]

It can be handy to carry a spare pigtail for a Campingaz bottle in an emergency if only because Campingaz 907 (butane) is so widely available in Europe.
