Need a gas cooker but have no gas supply I am not sure about the terminology, i.e if it's called an electric cooker, burner, stove or something else.  So I'll just refer to it as a electric or gas cooker to simplify things.

We don't have a gas supply to our house in the UK as we have moved to a more remote location.  We did have a gas supply in our old house and are finding the electric cooker in the new house extremely slow.  So I started looking into bottled/cylinder gas, but I am not sure which direction to go in as I have so many options.

For example, do I get butane, or something else?  Which kind of pipe will I need, what kind of regulator will I need? What kind of cooker will I need?

So far I have seen the following, but am not sure if these are safe for internal use and also I am not sure if these are the most economical options.  1 of my requirements is that I need a nice strong hot flame to I can get cooking done quicker.

Gas cooker

Regulator

Pipe with clips

Gas
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.
