What colour gas

[Mimi2]

We have always used green bottle gas for cooking, hot water, & mobile heaters! Are we right?

[Deniz1]

I have used both. Maybe my imagination but the blue seems to run out a little quicker than the green.

[Jonnie]

Its all pretty much the same, largely butane content which means it struggles a bit outside when very cold here as the BP is quite high for a gas.

I think the blue gas is under less pressure, so there is less of it in a cylinder.

[Gavin Simons]

I understood that they are the same (butane) except you can buy the blue cylinders without an exchange.

As for pressure within the cylinders, that remains fairly constant depending on the outside temperature and the vaporisation rate of the gas, which is in turn dependent on the rate you you draw it off! At this point it all gets far too complicated!!! So if the blue one runs out quicker I'd assume there was less gas in it to start with.

I always thought one was Jet gaz and one was koop until the other day when my koop green were rejected as Tempo only sell Jet green there goes my theory Thank goodness for supreme
