This pick up and carry gas heater is lightweight and compact making it a truly portable heater. It runs on the uno gas cartridge which is a disposable cannister and will run for approx 3hrs 45mins. (I know as I have one on by my desk in the colder months. This is the run time with the heater being on continuously). The body can be tilted to allow directional heat, you can regulate the temperature and it has it's own ignition. Ideal for tents, folding campers, trailer tents, caravans and home you must ensure that it used in a well ventilated area.
