    Just realised that our new ( to us!) Hymer 584 has a butane gas cylinder and we are planning to go away this weekend plus over Xmas - what temp does it stop working/ supplying gas at? I am aware that propane is the one to have in low temps - thinking of converting to Gaslow 11kg instead of paying to change cylinders ( £30 rental + £20 for gas).

    Can you recommend any fitters for the Berks area - near Reading?

    Weather forecast for the New Forest is 3 C overnight - will we have any problems?

    :Smile:

    Hi Scottie

    You will need propane in winter, can't recall the exact temp butane stops evaporating but it's around 0c .. however, before it reaches that temp. it will stop working effectively, not worth taking a chance. Most people run on propane all year round.

    More info on the Calor Site

    You can exchange your butane bottle for a propane at no extra charge, all you need to buy is a propane regulator, about £5 . Also worth checking the rubber pipe for signs of deterioration and replace if needed..


    Sorry, can't help with the Gaslow

    It freezes at 0 degrees C
    BUT using gas chills the bottle significantly so with a big take-off demand like a heater the gas itself cools down more than the ambient.
    So for the bigger demands you can run into problems from about 6 deg C the more so if the cylinder is getting low as there is a smaller amount of gas to chill.

    If its only the fridge running and the bottles quite full you will get away down to your 3 deg C.

    Leave the locker door open to allow the self cooling air to drop out; the last thing to do is to insulate the bottle that makes it much worse.

    If you have already got a Butane cylinder you can change that with most suppliers for a propane without any additional rental charge; just a pity if its got still some gas in it. You will need a different coupling for the propane cylinder and how you do that depends on whether you have the regulator "on" or "off" the cylinder.

    pick up a spare propane bottle from your local tip for £10, then buy a propane refill adapter from ebay. Hey pronto a refillable gas bottle for under £50. Job done, You will also need a replacement regulator. (Don't forget to use up the butane next summer)

    Wrong the GAS does not freeze, it does not change from liquid to gas at low temperatures . Propane is the one to use at low temperatures as it gasses from liquid at much lower temperatures, if as you say you will be at -3 degrees Butane will be useless,

    Whilst correct its a somewhat pedantic response in the context of the question; I thought we were here to try and help others. Thanks!

    I am surprised to see you giving this advice to a reader Roger ,and I don't know of any outlet in the Southampton area who would let anyone indulge in this dangerous practice.:Angry::Angry::Angry:

    Although we do use propane all year and even indulge in reckless re-filling with an adapter:Eeek:, butane does have the advantage of being denser and therefore you can carry ~ 12.5% more gas in the same size cylinders which equates to about 10% longer duration, given the slightly lower calorific value.

    This from someone who thinks gas freezes, we are here to help others, not cause death or injury to people and serious damage to property, tell me where you are able to refill bottles in this way without hiding behind your van or something so as not to be seen and stopped from doing it, and what about OVER FILLED bottles, you all know the dangers and one day you will be enjoying hospital food or worse DEAD.:Doh::Doh::Doh:

    Surely that will keep everyone happy.:Wink:

    Just pick up any size of Calor, propane or butane, and they will (should) exchange it for whatever size of bottle you need.

    There are plenty threads on the best ways to refill etc. but this should get you through this break.:thumb:

    No axe to grind here each to their own I just wonder, if owt went wrong Gaslow being a recognised system would your insurers pay out? If not could you not sue Gaslow? How would you stand refilling a standard Calor bottle? :Doh:

    As of yet/now I am not aware of any refill incidents with refill adapters but there are plenty of leaks / sticking floats etc on other systems :BigGrin: You are not allowed to refill Calor bottles :Wink: so buy your own :thumb: Insurers are a law unto themselves and as such can not comment on any payouts or not (would you tell them you blew the van up filling my gaslow system / bottle with adaper ?)

    Lets for a moment forget filling a calor bottle .In the reimo catalogues for years you could buy a refillable gas bottle . There are lots of different makes throughout europe.
    They sell a kit for filling german gas bottles outside of germany. It contains 4 different nozzles. Part no.75136.
    Filling of gas bottles as been done for many years through out europe and the rest of the world.
    Care and attention needs to be taken nobody should try or do it with out being confident and have some prior knowledge of how its done.
    As for calor ,well they say not to fill their bottles .They own the bottles. Lets be realistic how many people have a signed agreement with calor?Even how many know that there is such a thing.The agreement last 50yrs it is not a rental agreement nor does it transfer title of the bottles. so if you dont have a refill agreement you are breaking the law.
    Thats most camper owners i,m sure.
    Its as bad as carrying 20 litres of petrol in your camper. you break several rules if you do.
    cheers alan.
