Hi all... any advice on this will be most sincerely appreciated. :-)
First of all - am I right in assuming that the gas pressure from a 4.5 butane cylinder and a 7kg butane cylinder (or is it 6kg?) is the same? I.e. would I be able to run the same appliances from either cylinder?
I have three gas appliances and take one 7kg cylinder which is shared among them as and when, but I'd quite like to take two smaller cylinders instead (especially as I have no clue as to how much gas is left in the bottle, so if it runs out...)
2. Connections. Can I use this? It states "for LPG only", but butane is a type of LPG, right? (That's what it says on the net). If not, I'd be grateful for some other options where I don't have mess around pulling hoses off etc.
Any other tips on connections etc. which make life easier, are welcome!
The pressure supplied by the regulator should be the same (28mb in the case of butane) irrespective of the cylinder size, but if you're currently using a clip-on regulator on a 7kg Calor cylinder you'll need a screw-on one instead for the 4.5kg one.
Link isn't working, but yes, you could use a quick-release coupling.
To check how much gas is left in your cylinder, weighing the bottle and subtracting the tare weight (marked on the collar in pounds and ounces - just to complicate matters!) will give you the weight of the remaining gas.
yes you could use these but you need 1 for each appliance gas pipe unless you are contemplating removing the fitting from gas pipe of each appliance in order to fit it to another? I really do not see any advantage.I would imagine that each appliance you have is fitted with a gas hose & a suitable regulator.The coupling you mention would allow you to use 1 regulator but you would need to fit a coupling to each appliance hose in place of the regulator already fitted.
price wise it is dearer than a suitable regulator IF your appliances do NOT have them all ready fitted
thanks for the advice, all taken on board and order placed.
old chap, on the 4.5kg cylinders, the hose has to be pulled off the regulator which can be tricky. also, the coupling attached to each appliance will solve the problem of different regulators on different sized gas cylinders.
We use the 7kg Calor and each cooker has its own gas pipe and regulator . Luckily the 7kg uses a clip on regulator that can be changed in seconds with the turn of a switch.
To kudge what left weigh the cylinder on a bathroom scale, subtract the tare weight ( silver circular collar on the cylinder neck is stamped with this weight) and what you have left is the gas remaining .
Only roughly your cylinder empty weighs 9kg your cylinder on the scale is 12kg so it must have about 3kg gas or under half full .
