The short answer to this question is: no. The long answer: nope, nup, no way, don’t do it!
That’s not very helpful is it? Let me expand a little on why it is a bad idea to use a gas heater in a tent/caravan/campervan/garage/shed/enclosed space. But first, a few facts about gas heaters, such as the little Mr Heater Portable Buddy Heater and Companion Portable LPG Heater that we stock.
What Sort of Gas do They Use?
Most heaters intended for camping and outdoor use are fuelled by either butane or propane. Butane usually comes in small canisters and is most popularly used with those lunchbox-style portable stoves. Propane is better known as LPG – liquefied petroleum gas – or LP gas and too comes in small canisters, or refillable 1-9kg bottles. Yep, the type you use with your BBQ or camping stove.
