Propane gas?

Today i took the butane gas bottle out of my van, and replaced it with a propane (red) one.
I have done this so i can use my propex heater when it gets to freezing point,as the butane is likely to freeze.
I just want to know is it ok to use propane all year round,and is there a difference in performance between the two gases?
If not i will just use propane all the time from now on even in the summer months.
Regards Lee.

no difference to the equipment they can run on both. Butane is slightly more calorific content for the same volume but propane is massively cheaper. I run propex cooker fridge etc all year on propane.

yep propane is the way to go, plus only one basic type of regulator.

Lee, if you have replaced your butane gas bottle with a propane one don't forget to fit a 37mb propane regulator as in Metalmick8y's post. Butane has a different regulator which iirc is set at 28mb.

Thats cool then,i will stick with the propane.
Bowton lad i put the new regulator on as well,i got one from just kampers a while ago. Cheers anyway mate.

Propane has a higher calorific value that butane, approx 850kj/kg more, so burns hotter. It makes sense as there's an extra CH3 group in every molecule. In fact when i run my heatsource 2000 on prop there's a definate increase in the heat output. This is the reason that propane is used as household gas and you see all mobile caterers using propane bottles instead of butane.

smarty pants!
http://en.wikipedia.org/wiki/Heating_value , got that the wrong way round then. I dont think you can conect a butane regulator to a propane bottle they are physically designed not to fit.

he he he
Propane --- 2,219 Kj/mol
Butane ------ 2,800 Kj/mol

Hi Robin
yes there's a noted difference propex bunr much more efficiently on propane
