907 gas refill cost

Is it safe to run a gas heater like that inside ie open flame
Personally I've always been paranoid about carbon monoxide
But I could be totally wrong
we only use these OUTSIDE, in the gazebo.

or in the front Tent porch area.

they are good radiant heaters, we dont use them inside the van if thats what you mean.
 
back on the 907 gas bottle. . .


we used this HeaterBuddy gas heater at Silverstone last week.

they work great.

but the Propane gas bottles are expensive, . . .

so we got the converter adapter and uses these C500 cans instead.

  • 'Comes with adapter for butane and propane cartridges with EN 417 thread (7/16 x 28 UNEF)

the question is. . . . what do i need to get this running off a 907 gas bottle. . . . . ?




.
looks like this is one option,

to go from 907 reg + QR hose,

to this QR to (1"/20 male disposable 1lb propane connector) adapter

another option,


seems to be to get a Propane refill hose set. ( and refill the 1LB bottles)


though its tricky . .


looking for a 27mm propane UK clip on connector,

prob a w20 hose,

then the tricky bit,

the 1/20 1lb colaman propane connector,


with a check valve or at least a screw valve.


been looking for an hour. . . .
 
i have a question for you very clever Gas knowledgeable people. . .


we have one of these from Costco from the other month,

Not so much a gas issue more a physics issue.

Your problem isn't the regulator or the gas mix, it's the size of the cylinder.

Whenever you use a liquified gas it needs to turn from a liquid into a gas - and that takes energy exactly the same as when you boil a kettle and the water turns from liquid into steam.

Now in a gas cylinder it's doing that because you are releasing the pressure that's physically forcing the atoms in the gas together back into a liquid - but when the liquid vaporises it still needs energy and it will take that from the environment. Hence why all gas bottles chill themselves.

The smaller the bottle you use the less thermal mass it has so if you use the gas at a great rate the remaining liquid gas will chill itself down a lot and with much less heat energy the rate of vaporisation will drop even if the pressure is "right"

In your case the issue is the burner is using gas at too great a rate for a 907 cylinder so it's getting too cold. It's why it says to run them off the much bigger 9-13kg cylinders.
