Are mobile gas (butane) heaters safe for use in the home? What are the pitfalls?
I've not used one for a while but did quite frequently in a past life.
The only thing that got to me was a) the smell when you first ignite (try and do it with some ventaliation) and b) the amount of condensation created as a by-product of combustion.
...that a cannister of gas lasts about a week.
