This is doing my head in. I live in an electric only home. If the electric goes off for any significant amount of time then I will have a small problem, several small problems actually, but I'm looking at a small but important one, that I might be able to sort out a solution for. How to cook and make a cuppa. I am aware that little gas rings can be bought, for camping, but the canisters seem not to last long, and are expensive - cost for ring and 4 canisters (maybe 2 hours a canister) seems to be in the a bit under £30 range. Okay for warming stuff up, and making the odd drink, but not for cooking. Next up are things that use an external, but still small, canister. These last around 6 hours a canister for roughly the same as each little canister costs and seem to have a mini regulator. Cost for a basic ring and a 6 canister pack seems to be about £45. Maybe enough gas to last a week or 10 days from what I can gather. Next up is getting a calor gas cylinder and some form of compatible camping cooker, and a regulator and hose/clips. I can't figure this out, it looks like used as a main/only cooking source that even a small (4.5L) would last over a month, but I can't figure out how much it costs, or where to get one from, that will deliver. There may be, only seen the page once and can't find it again, some form of contract to get a cylinder in the first place, on the page for it they stated that online ordering and delivery to my home was possible, but when I go to order it says that deliveries are not possible for this product, for all the cylinders they sell. None of the 3 systems, and I'm getting the strong impression there are more, seem to be compatible. They all use numbering that obviously means something to someone who understands the system, but I don't, so its just gibberish. All I want is hopefully a backup, that will never need to be used, enough gas to last a few weeks, and a device to use that gas to cook with, preferably compact enough to it can just be stored, indefinitely. Just in case the power goes out for a while, so that I can reheat and preferably cook stuff. Just as a mental comforter. Not that I'll ever need to use it. Anyone understand the whole camping/calor gas thing enough to suggest what I need?
