I purchased this propane heaters for an Arizona camping trip in mid-February. I knew it was going to get below 40F and it did. The ground outside my tent froze, but I was warm within. Now I must say that staying warm had it’s caveats. I have an elevated air mattress, so I had to position the heater atop a chair and it sat there firmly (I did not feel that it would fall as this unit is solid if not exactly heavy). I then had to place the chair within a few inches of my bed in order to feel the heat. This is due to the fan within the unit being somewhat weak. Now if you are simply heating the space itself, anywhere would be fine, but I needed the heat specifically on me.
Pros: There are two ceramic plates that heat up in the unit. They glow a bright orange when lit (are silver when unlit). This allows you to go full bore on the heat using both plates, or be more economical, depending on what best suits your needs. The pilot light is a small flame which stays lit near the bottom/center of the device. If you nudge the heater or bump it, the security safeguards will cut off the flow of gas to the pilot light requiring you to relight it. I had to do this a few time, but I didn’t mind. It’s all for safety. It’s also fairly lightweight (at least to me) and the handle at the top was very strong. I felt very comfortable moving the unit even when the pilot light was lit. The unit was also VERY quiet, even with the fan on!
Cons: I really didn’t have any, but if you have sensitive or weak hands, you may find it difficult to pry open the sides where the containers go. The clips are pretty tight.
I would definitely use two cannisters instead of one for this portable propane heaters. Using one cannister will result in the unit drawing so much fuel that the can will freeze and the flow will stop. Using two cannisters, I was able to keep the unit lit all night at the highest temperature-VERY comfortable! You do have the option by using a specific hose adapter (NOT included) of attaching a 20lb tank. This would extend the heating time tremendously.
All in all, this unit performed EXACTLY as I wished and was perfect for me. I’ve also used it twice in my living room about a foot or two away from my feet and it feels great. If you need something with more fan power, I’d suggest lining up a stronger fan behind it blowing through it.
I thoroughly recommend this Mr Heater MH18B portable propane heaters.
