Boring gas bottle question??

[Nick2]

I have two gas bottles connected together and have always replaced both together as they seem to empty at the same rate.

Is it possible to just replace one at a time as we seem to use very little gas over the season?

Thanks

Nick

You will need to get the pipework altered to just have one bottle in use at a time.When one runs out you then connect the spare and get a refill at your leisure.

Change to calor, they've got a valve on the cylinder.

Got a gas tap for switching between two bottles. Never used, surplus to requirements, £10 + postage if it's any use to you. If so PM me.

If the cylinders have taps on them, only turn on one tap. When that one is empty, turn it off and turn on the other one

You can get afitting from a company called "Gas Low" for linking 2 bottles together from your local Calor dealer.

I am curious and wonder if someone could explain.

I get the impression from the posts that LPG cylinders in UK do not always have valves on the top? If that is so, when they are filled how are they sealed?

In our case they have valves, we just manually disconnet and swap the connection to the other cylinder in the locker (we carry two 9kg ones not manifolded together) which is no hassle as the empty cylinder has to be disconnected in any event for refilling.

The Camping Gaz cylinders have a stainless steel ball in the neck which is sprung from below and seals the cylinder. When you screw on the boat connection the ball is pressed down allowing the gas into the boat system as far as the first stop valve.

Thanks very much for that.

Following your post I have had a quick look at the CampingGaz site and I see how it works. Only little cylinders up to 2.5 kg though by the look of it.

Have not seen that method used before for refillable cylinders - the smallest commonly available refillable cylinder here in NZ (and I think Australia too) is 4.5kg but I think that the 9kg ones would be by far the most commonly used.

A serious flaw with Gaz is also....

...that it is almost imossible to install a new cylinder without a substantial amount of gas escaping.

Unless you have a very long length of rubber pipe that allows you to screw down three full turns you have to invert the cylinder and screw it onto the connector/regulator block. This would still leave a wound rubber spring around the fitting which I have known, in the past to loosen the connection. CAmping Gaz is really intended as that, for open air camping applications. Modern boatbuilders use the cylinders because of easier installation as well as universal availability. On that point though, although the cylinders in the northern Adriatic are identical in design, it is very difficult to get a blue one exchanged for their orange painted ones.

Re: A serious flaw with Gaz is also....

I'm fortunate in that my gas locker holds 4 Gaz bottles and the lid opens to uncover the whole lot. The flexible pipes (2 bottles connected, 2 spare) are long enough that I can lift clear of the other bottles to connect/disconnect. To connect, I engage the first couple of threads (ball valve still sealed) then hold by the regulator and just spin the cylinder to tighten. There is a very brief hiss but insignificant loss of gas. I don't like the idea of turning the cylinder upside down as the pressure at the connection is then greatly increased so I understand. I would post a pic of my gas locker if anyone was interested enough to explain to an idiot how to do it! Many boats are designed with poor gas storage arrangements, I'm sure we're all agreed on that!

Connecting Camping Gaz

I agree with the system, but you don't need to have a "couple of threads" engaged. Half a thread is ample, just enough to lift the cylinder to allow it to be turned under the connector.
