Filling gas cylinders

[ColinM50]

We've got a 6Kg lite cylinder in our motorhome and on a camp site last week I was chatting to a chap who does gas deliveries for Air Liquide. I jokingly said my cylinder was running out and what's the cheapest way to refill it - Calor want c£23 for the 6Kg cylinder which seems a bit pricey.

Anyway chappie tells me he always refills his cylinders himself. Says Calor don't like it but as long as you treat it carefully it's as safe as refilling a car petrol tank and who's to know?

He says you just connect the small empty cylinder to a full big propane one using a transition fitting (?), open the valves, empty one first and you'll hear the gas transferring. Stand the empty cylinder on a set of bathroom scales before you start and turn the valves off when the weight's gone up by 5Kg to be on the safe side.

Anyone any thoughts? I've got a spare full 15Kg blue butane one that I used on the old gas Barbie so no cost there. Is there any REAL difference in the gas? I know propane works down to a lower temp, but apart from that anyone foresee any problems?

Don't propane and butane use different pressure regulators?

How new is the MH? The appliances won't necessarily be certified for the "wrong" gas so it could cause issues if you wanted to get some guarantee work done.

I had my MH go up in flames on my drive, nothing to do with gas cylinders, but a scary experience.
The point I'd add is, the insurers go over things with a fine tooth comb, for the sake of a £23.00 gas bottle is it worth potentially invalidating your insurance?

£23.00 does sound a lot for a 6Kg refill though.

People do it.
