The way you buy gas is often dictated by the amount you are purchasing. It can be divided into two groups:
When you purchase something these days, you often want to try and compare the different suppliers. There are often ‘smokescreens and mirrors’ which can make it difficult to directly compare all of the suppliers when buying a gas. Hopefully this article can popint you in the right direction on…
Smaller gas bottles are fairly straight forward to purchase if they are disposable.
For larger gas bottles, a lot of the decision making comes down to the type of gas and the size of bottle (cylinder) required.
Each supplier will often have their own different sized bottles and rental agreement (if purchasing gas in larger quantities). So how do you compare?
The size of gas bottle (and where you buy it from), may be dictated by a number of factors:
The refill cost is often dictated by the volume of gas. Note that:
There are three types of gas bottle rental I know of. These are often dependant on the size of bottle (cylinder) and their usage:
The volume of gas is often advertised by the size of the bottle. But this doesn’t tell you how much gas you will get. The actual volume of gas will be dependant on the pressure used to fill the bottle. For instance:
This will give you the actual volume of gas supplied…
|Gas Bottle Sizes – The Actual Volume|
|Gas||Bottle (Cylinder) Parameters|
|Pressure (Bar)||Bottle Size (L)||Volume (m3)|
From the table, you can clearly see the how the volume of gas supplied changes with the bottle (cylinder) pressure.
How heavy (tall) is the cylinder (bottle)?
Not easy to answer, as everyone’s usage is different? However, you can often take a petty good guess:
You could calculate it, but if you are unsure on the size of the bottle you want, you will probably be guessing at the figures needed to calculate it. So if unsure, always ask for advice.
And the most important question of all…
