    Sure there must be a thread about this, but I couldn't find one :rolleyes:.

    Are there any other disadvantages of a manual changeover switch for Gaslow (or similar) other than having to do it at a possibly inconvenient time :eek: ?

    Equally are there added disadvantages of an auto switchover other than possibly not knowing when you're about to run out of gas :(?

    I suppose if one only has a single cylinder or an underslung tank, the debate is moot :).

    We've got an auto. It was on the van before we had Gaslow so it stayed in place although we almost certainly would have had one anyway. I don't really accept the not knowing when you're going to run out of gas argument unless you pay no attention at all. How hard is it to open the locker once every few days/weeks and look? You would have to do this anyway with a manual changeover. It doesn't take long to get used to how much gas you are using so that you usually have a pretty good idea of how much you have left.
    Also you don't need to run out before you fill up. You can top up as often as you like so, just like with your diesel, there really isn't any reason to let it get low enough for running out to ever be a possibility. For us I keep an eye on it and usually as soon as it's changed over to the second bottle I'm looking for somewhere to top it up.

    Manual on the other hand. I'm not sure I would want to be messing around with a manual changeover half way through cooking/first thing in the morning/late at night/just out of the shower/when it's pissing down (delete as appropriate) because the one thing you can be absolutely certain of is that you will always need to do it at the most inconvenient time possible.

    Auto in my view, I always check gas levels before I go away so I know how much I have. Before I leave site homeward bound I top up for the next trip If required. Simples!

    I have auto changeover with a Remote Duo C, shows which cylinder you are using.

    Auto changeover is not needed on gaslow/alugas etc, just leave both valves open and you get the same effect of just one larger tank. I have remote gauges on both tanks and normally just have one turned on but could be both.

    Single 11kg Cylinder - fill up before I go anywhere and I have never run out of gas.

    But after the most recent habitation check I found a leak. Didn't have it before, I have no idea what the guys did to break the thread seal (Loctite?) applied by Gaslow. I stripped it down and replaced with PTFE.

    Another reason why I will be doing my own maintenance from now on (y)

    Do you need loctite on gas? Brass to brass? Thought not...

    PTFE on gas joints, even if it's the correct gas type, is a bad idea. Use Hawk White or something similar.

    I had a twin Gaslow system fitted when we bought the Hymer which had a Truma Triomatic auto changeover regulator. When the Triomatic packed up (at around 8 years old) a direct replacement was no longer available so I switched to a Gaslow (Clesse) regulator with Gaslow manual changeover. It is very simple to use (just decide which bottle valve to open) and it includes a gauge to indicate how much is in the bottle. With a twin refillable system, an auto changeover is nice but not vital, since you can refill the tanks whenever you feel like it. The only time I have felt that an auto changeover might be useful is if I think one tank might run out during the night or during heavy rain (and I don't want to get wet). In practice, if I know that the in-service tank is getting low, I simply switch over to the full tank instead and fill up within a few days.

    As an aside for Hymer owners with the original Truma ex-eis controller that may no longer be in use (similar to the new one shown in Lenny's picture) you can replace the redundant Truma unit with a spare Din 12V socket as there is power to that point from the EBL.

    When I fitted the Gaslow system in our first van I put an auto changeover valve in, as sods law states the bottle will empty in the middle of the night and the fridge will start bleeping, or worse halfway through cooking the dinner and its tipping it down!

    I was quite surprised to find that when we bought the Pilote it had an auto change over valve fitted as standard.

    Still have the Gaslow one as a spare though.

    Why bother having a manual changeover when all you have to do is open the valve on one bottle and close the valve on t'other?

    To me an automatic changeover is just something else to go (expensively) wrong. Yes, in theory it does usually run out at an inconvenient time but, as posted above, you quickly get used to how much gas you're using and can anticipate it.

    As far as the accuracy of the gauges, well the words "chocolate" and "fireguard" come to mind......

    Manual for us, just leave both valves open or open the big tank and have the small one in reserve. Your choice.

    We've only got a single 11kg Gaslow bottle in our current camper as that's all that will fit in the locker (either that or two 6kg ones but we had the 11kg already), however our new Globecar camper has a much larger gas locker so as we picked up a new 6kg Gaslow R67 cylinder for less than half price at Peterborough show we'll be fitting that alongside the 11kg one. We'll just use the 11kg one until the gas level drops into the red, the turn that off and the other on, then think about filling up - we use around 1 litre of gas a day normally so the 11kg should give us up to 20 days and the 6kg at least another week ... such luxury! :D

    With the Gaslow manual changeover, that is all you do. The changeover unit requires no user intervention; it is merely a common junction between the tanks with a spring-loaded ball valve between and a volume gauge connected above. Changeover is effected by closing the valve of the tank being taken out of service and opening the valve of the new (full) one. The 'changeover' unit merely blocks the flow from the off-line tank and shows the contents level of the tank in service.

    So basically the manual changeover is a bit of a chocolate fireguard ... no better than the bottle gauges!

    Not sure I understand the relevance of that last post. I think for more information you would do better contacting Gaslow directly and asking them.

    Totally agree, don't have an auto change on my Alugas system, no need for it , as I have 2 hands both capable of turning a valve wheel on and off, and with practise I have it down to 4 seconds for changeover, but OH says I'm too slow and need more practice, no pleasing some people :rolleyes:(y)

    I bought a Gaslow system with an automatic change over.

    I do not have the personality to operate it.

    You have to know where you are with your use of gas.

    This means you have to check from time to time which bottle you are currently drawing your gas from otherwise, as happened to me once, by forgetting to check, I ended up with both bottles empty.

    I stopped using the automatic change over that very day.

    I fill the bottles and shut one off. When I run out of gas I manually switch over to the full bottle and know I have to fill up at the next opportunity.

    Never ever ran out again...
