Gas Cylinders

[KAM]

During the 4.5kg gas crisis I started filling my own camping gaz cylinders. I found them a bit small so have gone back to the 4.5 kg calor. I thought I'd filled one last year but can't manage it now. A web search was inconclusive as to wether calor have a non return valve. Anyone know? Flo gas won't fit my locker unfortunatly.

I’ve definitely filled the Calor 3.9kg propane from larger donor bottles, so no non return valve there, and I would be surprised if there’s a non return valve in blue bottles, though there will almost certainly be one in the regulator. Have you a ‘pigtail’ hose that’ll fit calor blue bottles? Should be straight enough process if so.

I've filled 5x 4.5kg bottles with no problems.

It would be difficult to fit a non-return valve as it is the only connection to refill the bottles at the Calor depot

They now seem to be back in circulation. Bought one on exchange at Shepperton Marina - £47

The only bottles we never successfully managed to decant gas out of were the USA ones and they, along with all the others would accept a gas transfer.
You have got a 'free-flow connection fitted at either end of your transfer pipe? You can't transfer through a regulator.

A friend recently bought the kit to transfer butane and we shared the cost. Two 907s filled from a 15kg Calor butane and the kit has already made a saving . Ongoing 907refills will cost £12 in gas at todays prices compared to £50 per 907 refill/ exchange from the marina. Both our boats have gas lockers designed specifically for Campingaz 907's so not viable to convert to a larger butane cylinder.

Donor bottle upside down with some gas in it? receiver bottle a metre below it? Both valves turned on? I can't think of anything else that would stop your transfer. I am decanting into Campingaz bottles, though.

Cheaper still if you fill your calor bottle at an LPG fuel station with one of these. Some discretion is required.

I suspect by discretion you mean filling of loose cylinders (at a lpg station) that are not intended/designed for self filling is not allowed due to the risk of over filling.

Yes, that's what I mean. I have a perhaps misplaced confidence that, when filling an empty cylinder, I can stop filling it after delivering 80% of its capacity.

Thanks for the advice. Might just be too cold!

When it was cold I poured a kettle of boiling water oven the donor bottle.
I also insulated the hose with pipe lagging.

Speeds things up if the donor bottle is a bit warmer than the recieving bottle. I put a towel over the donor bottle and pour some hot water over it.

 

[snowbird30ds]

Put the receiving bottle in the freezer and stand the donor in the sun first.
Makes a huge difference.
