Even working on projects indoors and away from the elements can be tough going when the temperature drops. Industrial outdoor and job-site heaters may be portable, but can be cost probihitive for garage, workshop, basement, or boatyard use. Propane powered portable indoor heaters are perfect for inexpensive and fast heating of large indoor spaces. Propane space heaters provide heat for barns, sheds, cabins, campers, patios, garages, sporting events and more. Modern propane heaters are as efficient and safe as electric heaters, and connect to standard propane tanks of various sizes.
