Need a gas cooker but have no gas supply
Those little single ring gas stoves are really intended for camping use, or emergency use at home (during a power cut). The cylinders for them are very small and don't last long.

Any standard gas hob can be "re-jetted" to take bottled gas rather than mains gas; they often come supplied with a conversion kit for this purpose. 

The normal thing to do is have an outside wire enclosure containing two large gas bottles and an auto-switching regulator (so when one bottle runs out, it switches over to the other bottle). The two bottles system means you can use the second while the first is being refilled / replaced.

You'd normally use propane for this rather than butane; butane becomes unuseable around 0C so can't be stored outside.
