which is best and or :wave:more available blue bottle butane or red bottle propane

They are both pretty much as available as each other, although the 6-7kg seem to be the ones that sites have the most of.

I would just say that if you're going to use quite a bit, which many MHs do - I can really recommend installing a refillable bottle with an external filler point, the gas is less than half the price.

My first post on here, so I hope I got it right!

depends where your going and what temp it is, apparently. blue calor is said to have problems sometimes in colder climes, where as red propane is better at lower temps.

I dont do europe or skiing etc, but i do use propane and dont bother changing, but i only do uk touring.

Hello Colin Welcome aboard. Propane burns hotter than calor is all I know

Both types are readily available especially Calor, Propane [ red bottle ] is better for use in very cold circumstances as it will still turn to gas from liquid .

Sorry that is incorrect, Butane burns hotter, [ is more calorific ] that is why it is regulated at 28 millibars .Propane is regulated at 37 millibars.

i would say,if you stay in temperate climes,butane regulators are simpler to change and i find propane regulators a pain in the bum. i use butane in my van and propane in the house

Really it's all down to the regulator as stated, Propane lets more gas through hence the higher temp.

ok calm down i only asked i think i'll get one of each might even convert to nuclear just to be on the safe side do camp sites have waste disposal for this do camp shops do uranium :banana:sorry just had my appointment with dr smirnof

I only use propane, but I have a refillable bottle and it saves a fortune, especially if you use the MH in the cooler seasons

Full members get a discount from Gas-It see:http://www.wildcamping.co.uk/forums/motorhome-knowledge-base/16481-change-refillable-gas-10-mins-totaly-legal-legit-offer-wildcamp-members.html

Heating at half the price of Calor!!!

If you're crossing the Channel you cant get Calor!

Simple.

Calor only sell gas in UK.

Blue bottles are available all over Europe in garages and supermarkets, but its expensive!

If you're going to travel in Europe you need to get a refillable system (Gaslow, Gas-It etc) and perhaps carry a full calor as a back-up.

As stated, the advantage of propane is that it boils at a lower temperature and you can use it below 0 deg C. The advantage of butane is that it is denser so you get more gas out of the same size bottle - 7kg instead of 6kg. You do pay more for the extra butane, though - 21.49 v 19.99 from Calor. The difference in the regulator pressures doesn't affect the amount of gas coming out, the gases have different vapour pressures so propane has to be regulated at a higher pressure. Propane has a slightly higher calorific value, about 2%

What gas is used in the refillable LPG? is it a blend or just propane or something else completely?

hi depends what country you are in here in uk its propane .but as you go south they add butane . some places add pentane as well. but it all works . but a southern mix used in northern europe in winter might not create gas ,just stay as a liquid.
remember all bottles are refillable .or they wouldnt want them on exchange.

How can you do that? I use 47kg propane cylinders for gas cutting to be able to fill a small cylinder would be really handy ( and cheap). Is there a venting bit of kit available, or do you just connect one to the other and let the pressure equalise?

I discovered this so use the red bottles all year round. They work in the cold too whereas the blue ones pack in. So the kettle boils faster with propane basically :)

Sorry that is incorrect, Butane burns hotter, [ is more calorific ] that is why it is regulated at 28 millibars .Propane is regulated at 37 millibars.

Butane has a calorific value of 3200 btu per 1 cubic feet
Propane is 2500 btu per 1,cubic feet.


Butane generates a max flame temperature of 1996 degrees. Celsius propane a mere 1980.

The boiling point of propane at atmospheric pressiure is minus
42 butane minus 2 which makes propane better for winter use.

Size of cylinders are down to take off rate which is all down to demand on the system and is a seperate issue

30mbar is the current standard for both butane and propane
I have 28/30/37/50 ...and they all work fine with both butane and propane on my appliances

in france it is currently cheaper to buy in bottles than from the lpg pump [ which is propane ] , and the price of bottles is now very low , last one I bought cost 1 [ energas from intermarche ] although 5 is the price on their website

En1949 which spawned en12864 2001 annex d. Does prescribe regulators at. 30 mbar this is exclusive to motor and touring caravans, statics and houses still work on the 28 37 mbar regs
I posted a while ago peoples experience of 30 mbsr regs and there certainly from a user view doesn't seem any detriment..
7k


I am a qualified lpg gas engineer lav vehicles my specialism, the reason for my curiosity is the French standard of NSF 56 400 ran at pressures much greater than the applances required

We had 8500 statics dotted about Europe, made commercial sense to go 30 mbar on replacement regulators new commissions we could potentially source at a better price.

We remained Sat on the fence and still insist upon dedicated regulators for the specific gas used
