What To Look For
The 3,000 BTUs that heaters such as the Coleman ProCat deliver can put a quick end to your misery when it gets cold inside a tent. Propane heaters are the ones to beat because they don't have an open flame and they're safe in enclosed areas. If you buy a double-duty unit, it also heats water. Stick with well-known brands as the warranties, parts availability and support are generally better. If you buy a model that's "designed for indoor use," you'll end up with a safer product. A built-in oxygen depletion sensor that shuts off the unit when low oxygen levels are detected is a must-have feature. Make sure the heater has electronic ignition, inspect it for leaks and find out how its fuel is delivered. If you're willing to pay a little more, you can find some heaters with adjustable temperature controls and battery-powered fans. Having the ability to direct heat where you want it can come in handy.
Common Pitfalls
Because you'll be generating heat inside a tent, you need a heater that's safe in this environment. It's also wise to keep it several feet from anything that might melt or ignite, and to crack a window for air circulation. You might be tempted to buy a compact, lightweight heater instead of a heavier, full-size one. But smaller heaters put out less heat.
Where To Buy
Coleman propane heaters are top-rated and you'll find them at many stores. If you're shopping online, Amazon.com has the best selection, and its prices compete with eBay. Check the merchant's reputation before making an Amazon marketplace purchase. If you shop on eBay, try to buy from a power seller with excellent feedback.
