|After having read the labels on different heaters, I decided on this one and am glad that I purchased this one. I have used it in a canvas tent (10x14ft) and it reached a comfortable 68 to 72 degrees (at a 5ft ht.)while it was in the low to mid teens outside.
Hooked up to a 20lb. bottle, it lasted 2 weekends (one 3 day and one 4 day) before it used up all the propane. You do need a filter in between the heater and the hose to keep it working the way it's suppose to, and keep the bottle outside. BTW, this heater has 3 settings - low, mid, and hi. It's easy to use and no matches to light it.
Also, the fact that it has a battery operated, quiet, fan (uses "D" cells) helped keep me and my hunting partners warm in the tent, we really didn't need to zip up the sleeping bags, we also used cots to be up from the ground. Keep extra batteries on hand.
Again, I'm glad I bought this heater. I'l take it with me on each and every hunting trip where I use a tent.|
