Hi Ed,

Well yes it does, the prices can vary quite widely - although as the ex-refinery price of LPG is still increasing - it might be a good idea to buy it sooner rather than later.

Answering where or from whom would be cheapest - that's a different story - and depends on local circumstances.

In the UK you have (at the very least) the choice of buying Propane from Calor gas (it's this company that uses the red bottle), Shell-gas, Flo-gas, BP (Light Gas plastic bottle) and many others - and then you have the price differences between retailer outlets of the same gas.

If you say (roughly) where you are - then maybe people can post local prices to help.

One last thought - Propane and Butane bottles - you are aware that the fittings are different and if you don't have them already, you'll either need a new pigtail (new caravan) or a new regulator (at least)

thankyou, robert, yes we do have a new van,(i know, a bit excessive just to change the colour of the gas bottle).its my neighbours fault, he suggested that any camping outlet would charge more, (more than what ,im not sure) i thought it would all be the same price. we live west yorks. ive just ring my nearest gas outlet and the price seems ok.i might try some more though. thankyou again

Hi Ed, as Steve already says, any calor gas distributor will exchange a calor gas bottle, like for like or propane for butane and visa versa. They will also exchange any size for whatever size you want providing it is in stock. These outlets are usually the cheapest, a 13kg propane recently cost me

Hi, just while on the subject of gas, on a recent trip it was suggested to us by a fellow caravaner that we change our blue bottle for the red one. What is the difference? (other than colour) and can we change the fiting our selves.

Jennifer,

Butane (Blue bottle) is fine for summer vanning, but will not provide any gas when the temp drops to about 4 degrees C, as it stays a liquid in the bottle.

Propane (Red bottle) gives off gas down to below freezing, so will provide gas whatever the weather (UK weather that is).

There is consideration being given to the possible consequences of using Propane in hot weather, particularly in regard to vans fitted with bulkhead regulators.

The consideration is relating to the very high pressure build up that Propane produces in hot weather, and the ability of the Pigtail to withstand such pressures over prolonged periods.

This problem does not affect vans fitted withbottle mounted regs, as the output pressure is already regulated to 28mb, or 30mb.

Just to be on the safe side we use Butane in summer, and Propane in winter.

You will need the two different bottle fittings, or regulators if you dont have a bulkhead mounted regulator

Hi Jennifer,

Butane has a higher heat content than Propane - about 10% - so you'll use less gas to achieve the same outcome.

Propane has a much lower boiling point than Butane, so it still generates copious amounts of gas even at very low temperatures. Butane stops boiling around the temperature water freezes, so although we used it during cold snaps down to freezing, Propane would be better in that case.

Ultimately, it doesn't make much difference - if you area three seasons or Summer only caravanner then Butane is more efficient. If you venture out when it's -5C, then Propane is the only answer

Hi all

Butane freezes quicker than propane and propane is also hotter than butane.

Hello Lee

Your statement is not quite right,

With a falling temperature Butane gas will liquefy (not freeze) at around zero Centigrade, where as Propane liquefies at around minus 40 Centigrade.

Volume for volume, Propane has less heat energy than Butane, so you use more propane to achieve the same heat input to your appliance.

Rob...That is sort of correct. But the calorific value of both gasses of stored in identical 10Kg containers is almost identical. You are only correct if you talk in Volume so one gallon of Butane will have more calorific value than propane.

Sorry to pick. But as we buy it by weight you need to know the difference in the amount of energy stored in the bottles and if the weight is the same due to the heavier nature of Butane it will only carry the same amount of energy so both bottles would run out at almost the same time.
