    • Works great and keeps RV/hunting blind toasty!
Color: Red Style: Heater
The buddy heater is high quality and easy to use. It is compact but put outs a good bit of heat! We have a 35 ft RV and this heats the whole thing up extremely well. We also used this during a recent winter storm when our power and electric heat went out and it kept our family warm! Highly recommend as an affordable, easy to transport option for heating in planned and emergency situations. ... show more

    • An Amazing, Robust and Powerful Portable Propane Heater; I Use it Daily in an Outdoor Greenhouse Dome Tent Office Space
Color: Red Style: Heater
I have, over the past few years, grown tired of trying to use a small portable electric heater (with two heat settings, rated at 850W and 1500W) to heat an 8.5 x 8.5 foot greenhouse dome tent (the ceiling of this dome tent averages 7' to 8.5 feet in height) that sits in my backyard and has been adapted for use as an outdoor office and meditation room. This outdoor dome tent, which occupies about 72 sq. ft., and about 585 cu. ft. of space, and which has translucent plastic tent walls, sits on the ground, and the floor is a tarp sitting on the ground, covered with some old carpets for a bit of comfort. This dome tent is entirely uninsulated, and, due to the translucent walls that easily allow heat to escape even in the near-infrared (NIR) and visible light regions of the spectrum, it offers even far less insulation than would a tent structure of the same size/volume that used an opaque material such as green tent fabric. This dome tent is equipped with eight zippered screened windows (four near ground level, and four at a height of 6' above ground) and I always leave each window partially unzippered year-round to allow for the flow of fresh air into the dome tent; this is important at all times anyway for adequate ventilation, but it becomes doubly-important when using a portable combustion heater such as this heater inside a dome tent such as this! So, as a result of the factors that I have discussed above, this structure has always been somewhat of a challenge to heat using the 1.5 kW electric heater whenever outdoor temperatures have falled significantly below about 55 degrees F, and it has been impossible to get the interior to anywhere near even 70 degrees F when outdoor temperatures have dropped to 50F or below. So, I finally decided to stop using the portable electric heater and to upgrade to a protable propane heater that was rated and certified as indoor-safe, and that could deliver at least 8,000 to 9,000 BTUs of heat. I finally purchased (via Amazon Marketplace) this Mr. Heater MH9BX portable propane heater, which has heat settings of 4,000 BTU and 9,000 BTU, after careful research into each of the various brands and models of portable propane heaters available on the market. I particularly liked the stable and robust design of this heater, and the fact that it has auto-shutoff for tilting, auto-shutoff for low oxygen levels, and also because of the pilot light and the built-in piezoelectric igniter. At the same time that I ordered this heater, I also ordered a Mr. Heater 12; propane gas hose, and a Mr. Heater inline propane gas filter for use with it. When the unit first arrived, I tested it for a week using a 1 lb. propane tank as the propane fuel source, and then, when that first tank had emptied, I installed the propane fuel filter and the 12' hose running to a 20 lb. propane tank outside the dome. I am extremely pleased with the performance of this heater. It is easy to use, and it produces a lot of heat, far more than my old electric heater did on its high power setting of 1500 W. In fact, I have run tests over the past few days (late October 2013, at an altitude of 1,000 feet in the Appalachian mountains, where we live) in the early morning hours, at about 4 AM (three hours before sunrise), where outdoor temperatures were about 36 degrees F with a 2-4 mph wind, and where the starting interior temperature inside the dome tent was also 36 degrees F. Using this heater on the High heat setting (it is rated at 9,000 BTU at this setting), the interior temperature of the tent was raised to above 70 degrees F within 6-7 minutes from start (this is amazing to me!), and was raised to 82 degrees F within 25 minutes of start; the interior temperature finally stabilized during each test run at about 83 degrees F while the outdoor temperatures were still at 36F. Given the fact that this dome tent has a lot of interior volume for its floor dimensions, and also because this dome tent has very poor insulation (the average insulation rating for the translucent plastic tent material on the walls and ceiling is less than 0.1 R, and the floor, consisting of a tarp and some old carpets sitting on bare ground, also has about the same terribly poor R rating, and also beause of the fact that I always leave all 8 zippered windows in the dome tent partially cracked, I am amazed that this little heater is able to heat the interior to of this structure, in the middle of the night (therefore there is no incident heat from sunlight entering the structure) from 36F to 83F in a bit over a half hour; this is an increase in interior temperature of 47 degrees F (over outdoor temperature and over interior starting temperature) in a structure that is entirely uninsulated and that loses heat very rapidly! In fact, this is an acid test for a heater such as this, for this is a kindof worst-case test for a portable heater! My above-cited tests, along with others that I have not enumerated here, show me that this heater, on the High heat setting, should be able to keep the interior temperatures of this totally-uninsulated dome tent at a comfortable level down to outside air temperatures of around 20 degrees F, and should be able to keep the interior temperature at "usable" levels down to outdoor air temperatures of below 10 degrees F/ If I could give this little portable combustion heater an Amazon rating of 7 stars instead of 5 stars, I would do so! And now, since I am a scientist and an engineer, let me share a few caveats with you about the use of this heater, and of ANY portable propane heater: Particularly if using this heater indoors, you will want to be absolutely sure to follow the manufacturer's safety recommendations to carefully check all propane gas connections for any possible leaks after installing, and to check them again prior to each use, tightening connections as needed to eliminate even small propane gas leaks. When you are first starting the stove after having installed a new 1 lb. propane tank directly (i.e,. no hose used) to the heater, bear in mind that the pilot light will not immediately light, and that even when it first lights, it will likely go out (i.e., extinguish) a few times for the first 45 to 60 seconds, because of air present in the internal propane gas line. Thus, you may need to hold the pilot light control down for a few seconds to purge any air present in the propane line before the pilot light will stay lighted. In other words, after having changed tanks, remember to bleed the fuel line by holding the pilot light control down prior to sparking, else you will be "wasting" some sparks! And, of course, once the pilot light has ignited and stayed lit, it is important to hold down the pilot light control for at least 30 seconds until the internal pilot light safety thermocouple has warmed up sufficiently to allow the pilot light to stay lit. When you are first starting the stove after having installed a new external propane tank (usually a 20 lb. tank) using propane gas hose (they are available in lengths ranging from 5 ft to 12 ft) remember that ths hose will, at first, also contain a lot of air, and thus you will wish to bear in mind that the pilot light will not immediately light, and that even when it first lights, it will likely go out (i.e., extinguish) repeatedly a few times for the first 60 to 90 seconds because of air present in the internal propane gas line. Thus, you may need to hold the pilot light control down for a bit seconds to purge any air present in the propane line before the pilot light will stay lighted. Once any stray air present in the propane gas line has been cleared, the pilot light will then stay on continually. In other words, after having changed tanks, remember to bleed the fuel line by holding the pilot light control down prior to sparking, else you will be "wasting" some sparks! Late Update, as of October 27, 2018: This amazing little heater is still working perfectly! I love it! ... show more

    • This Heater Is Fantastic!!!!
Color: Red Style: Heater
We use this heater in our small greenhouse and it is perfect!!! We do use a small wood stove fan with it that fits on the top. They work great together!!!! Our first heater we had to return because the shut off safety device was jammed when it arrived due to shipping but with Amazon and Mr. Buddy it was easy and we received a refund and bought another one. We get about 10 -12 days of use with one 10 gallon propane tank only using it at night. We highly recommend this heater!!! It is safe, easy to use, and does the job!!! We like the size and weight. We do use the filter and hose that Mr. Buddy recommends and we have had absolutely no problems!!!!,πŸ‘πŸ»πŸ‘πŸ»πŸ‘πŸ»πŸ‘πŸ» ... show more

Color: Red Style: Heater
Excellent heater and so easy to operate...1 pound bottles only last about 6 hours at high...so with adapter hose for big tank bottles it last several days...I have a 20 pound bottle and it last for 5 days on low heat...very easy to work with. Puts out a lot of heat. Igniter is excellent, never fails, have used this every winter since buying Mar 6th, 21...to supplement my house heater so it doesn't come on every 30 minutes...great value, would buy again and my daughter has now bought one for camping in desert. ... show more

    • It works well
Color: Red Style: Heater
I been working on my boat while it is out of the water so no electrical things are on and this heater warms it up pretty well while I been cleaning it up and fixing various things. I did have to close off the forward cabin to get it to get things comfortable though, but all and all its pretty good.

    • Awesome for camping or emergency heating.
Color: Red Style: Heater
I have primarily used this to heat my medium sized tent while camping in very cold weather of 10-25 degrees. Despite my tent being big enough for a queen sized mattress and a table/cooler, the heater only needs to be on low to almost run you out of the tent and my tent is definitely not a winter tent. I have also used it in my small apartment when the power went out after the recent ice storm in Tennessee. On high it heaters my entire apartment very comfortably for over 12 hours and I don't think I used even 1/4 of my 20 pound tank. It seems to run about 5 hours on low on a 1 pound cylinder, and about 2 hours on high. I recommend getting the adapter for using larger tanks if you plan on using this for more than a couple hours at a time. I will also add I often have this strapped to the back of my ATV to get to the campsite, 4x4'ing the whole way, beating it around, splashing mud on it, and even got it wet a few times and it still works perfect. I've also accidentally knocked it over many many times, kicked it a couple times by accident, and more I'm probably forgetting. So this thing is pretty tough for what it is. ... show more

Saw one of these heaters at a friend’s home (they use it for camping in their Winnebago) and was impressed with the amount of heat it put out - even at the low setting. We wanted a small heater for backyard dining at our bistro table and it really does the trick. Looking forward to many dinners outside during the cool California winters. ... show more
