An Amazing, Robust and Powerful Portable Propane Heater; I Use it Daily in an Outdoor Greenhouse Dome Tent Office Space
Color: Red
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

Love my Portable Buddy!
Color: Red
I bought this "Portable Buddy" as an emergency replacement for the Mr. Heater "Tough Buddy" my son gave me 4 or 5 years ago -- the only non-breathing entity for which I've ever developed a deep fondness! (The man on the Mr. Heater hotline says it can be fixed, so I'm keeping it.) But I needed heat immediately! I've never been happier to see a package at the Post Office! Amazon had a better price than local stores AND could get it to me in 2 days! (No local store had it in stock and it would have taken them at least a week to have it ready for pickup.) That's far too long for an old lady to be cold. I bought the fuel filter, too -- I believe -- after some research -- that not having one while using a 5-6 ft. hose and a 20# propane tank led to the malfunctioning of my Tough Buddy. (I was able to clean the pilot light tube to get it to light, but -- alas -- it wouldn't stay lit for more than 10-15 minutes.) The new Buddy portable heater gives GREAT heat! I live in the mountains in the southwest... in a partly-historic adobe house. I have a furnace, but I hate the blowing air (allergies) and the noise. And I guess I'm just tired of tending fires, though my fireplace has a firebox in it the blows heat throughout the "beehive" exterior. After being in this house for more than a dozen winters, I decided that it was stupid and expensive to try to heat the house, as I live alone... with my companion dog; my objective these days is to heat myself. The altitude hasn't been an issue. The portable Buddy lights easily and gives the direct warmth of a toasty fire while the vents at the top warm the surrounding area. I love this kind of instantly-warming heat. There is no comparison in my mind to a warm heater (or fire) with fresh air in the house and the stuffiness of a centrally-heated house. I use the heater only in the evenings, for reading and tv watching; I warm up on "high", but soon find myself switching to "low" and moving the heater farther away. I would never let it run unattended. I enjoyed using my fireplace for years, but you just can't get a good fire going as quickly as you can fire up this little heater! Compared to my old Tough Buddy, there have been some improvements made to this heater: The attachment (to the 1# propane tank pictured, or to the hose connecting to a 20# tank) now swivels -- which would make attaching the 1# tank infinitely easier. And there is a new pilot-lighting mechanism, now part of the main switch. I'm not sure how I feel about this change: It's worked fine so far, but I'm wondering if it will stand the time test, as I consider this a long-term purchase. The handle on top now swivels back, and there is now an oxygen-depletion sensor in addition to the tip-over sensor. The tip-sensor (in my old model) only went off once; the heater can be slid carefully, just not bumped. My dog treats it with respect, but I'd be careful around small children. The Mr. Heater hotline man told me the Buddy was exactly the same as the Tough Buddy. It may be, mechanically, but the new heater is lighter in weight and a bit smaller; the pad that lights up and gets hot is vertically oriented (TB was horizontal.) However, it's quite sturdy, and the really important part -- its heating ability -- is the same. I love it, and I'd recommend it for campers, people working in shops or garages, sports people and to anyone who can safely use a 20# propane tank, which is so much more economical than the 1# tanks. Terrific for emergencies! The caveat is that it shouldn't be left unattended, including while sleeping. P.S. Buy the fuel filter. I don't know enough about these things to review it, but I can attest to the fact that impurities (including added odorrants) in propane and the plasticizers in some propane hoses can lead to the untimely demise of this heater without a filter. Also, save the box for off-season storage of the heater; dust and spider webs would have to be cleaned out before re-use. And I'd suggest actually reading the user manual. ... show more

The Mr. Heater Portable Buddy Heater (MH9BX) is easily one of my favorite overlanding products! I first discovered this heater through the Camping With Steve YouTube channel, and I can see exactly why it’s so popular. This little heater packs a serious punch, offering 4,000-9,000 BTU of radiant heat, and it’s safe for indoor use, which is perfect for camping or overlanding in colder conditions. What I really love is that it runs on the same 16 oz propane mini tanks that power my Coleman Stove, making it super convenient to use with the gear I already have. The performance is absolutely impressive. The heat kicks in quickly, almost immediately after the pilot light turns on. Within just a few minutes, the area around it is toasty and warm. It’s amazing how such a compact heater can heat up a small space so efficiently. It’s also incredibly clean and quiet once it’s running—aside from a very slight propane smell when first lighting, I barely notice it after that. It’s the perfect addition to my setup when I’m in the middle of nowhere and need to stay warm. In all seriousness, other companies should take notes on this heater’s design and materials. It’s clear that a lot of thought went into making it durable, portable, and easy to use. The build quality feels solid, and I trust it to keep me warm during my overlanding trips. It’s one of those products that you never knew you needed, but once you have it, it becomes essential. As a loyal customer, I can honestly say I’ll be using this heater for a long time. It's a lifetime keeper for me, and I wholeheartedly recommend it to anyone looking for a compact, reliable, and efficient heating solution for their camping or overlanding adventures. ... show more

Great little radiative heater
Color: Red
The thing to know about this heater is it throws off a lot of infrared radiation, which is the primary mode of heating. It is like having a little portable Sun with you. Like if you go outside and it is cold and cloudy, you will feel cold. But at the same outdoor temperature and the Sun beating down on you on a clear winter day (if you have clear winter days were you live), you will feel a lot warmer. A fun little thing to do if you have security cameras with night vision, light this up in view of one of these security camera's at night. It is brilliantly bright and everything in the line of sight of the hot plate on it nearby is brilliantly lit up. With the naked eye at night, you will just see a dim red glow, but the security cameras will see a blindly bright light as it is in IR night vision mode and the black body radiation is primarily in the infrared spectrum. This means when you are outside, basically regardless of conditions, as long as the conditions are good enough for this to work, it will be heating you up. You can even say leave this outside your tent and as long as you are setup to let the infrared light in, it will warm up the inside of your tent and any infrared light hitting you from this will warm you up, say you are laying there in your sleeping bag. It is almost like magic as most people are used to thinking about heating in convection terms while this primarily operates in black body radiative terms. I am not saying sit out there butt naked in the snow with this being your only device to keep you warm, but it is a greet supplemental heat source to help you keep warm when you are doing something sedentary outside in the cold. The one gripe I have about this is the flame is unstable and noisy on the low setting. This works best at the high setting anyway, so probably what you want to do and just forget about the low setting. If you use this with a larger tank with a hose, you may want to plan to shut the main valve off on the larger external tank a couple to a few minutes before you are done using the heater so that there is time for a pressurized hose to purge. As this only lasts a few hours on a 1 lb tank, you can quickly end up getting into using larger tanks with this. ... show more

Last Thanksgiving, my best friend and I went on our second overlanding trip near the Sequoia National Park, California. Temperatures had dipped to as low as a bone-chilling 27F, and water bottles froze while we slept in our cars. I was a bit more comfortable than him because the Peter Pan 100oz hot water bottle and 32F-rated sleeping bag kept me warm enough. We both were thankful, however, we did not bring our young kids or the struggle would have been more difficult to handle. I looked into safe ways to keep warm a car, tent, or anything indoor, and researched the following options: - Car window insulation - Warm sleeping bag / Rubber hot water bottle - Electric blanket - Fuel-based heater Insulating the car windows would provide an immediate boost to keep warmth from escaping, but that would have been impractical for tents. Warmer sleeping bags and hot water bottles are extremely safe options but would only help individuals that had them. Electric blankets could pose a small risk of fire or injury, require a lot of battery power to operate, and are not quite energy efficient. For warming a larger room or groups of people, I had decided on fuel-based heaters instead. ARE PORTABLE HEATERS SAFE? there are two, immediate risks and concerns with fuel-based heaters: - Carbon monoxide (CO) poisoning - Fire or burns when tipped over or flammable material accidentally touching the heating elements Are any safe for indoor use? Yes and no. They can be safe with the proper precautions and preparations. There always, ALWAYS is a risk of fire and gas poisoning, but overwhelmingly, the Mr. Heater Buddy series was the most recommended appliance for indoor/outdoor use for a variety of reasons. Nonetheless, the Mr. Heater is NOT 100% safe. IN A NUTSHELL The Mr. Heater Buddy series had been among the most-recommended, portable warmers rated for safe indoor and outdoor use. With proper preparations and precautions, that can certainly be the case even when no heater is 100% safe. Safety features like tip-over and low-oxygen sensors, along with a slightly open window and a separate carbon monoxide detector, can add to peace of mind while camping or staying in an enclosed space. Our Buddy MH9BX (F232000) model heated up very quickly with a standard 16oz/1 lb propane fuel canister and is rated to last between 3-6 hours. Longer runtimes can be achieved by attaching to a larger cylinder with an optional hose assembly. The fold-down carry handle can have a battery-operated stroller fan clipped on for more even heat distribution As previously stated, no heater is 100% safe. For instance, the tip-over sensor may not activate in certain situations, the low-oxygen detector cannot read potentially deadly carbon monoxide (CO) levels, and the grid cage is too wide apart to prevent smaller, flammable materials from slipping through and catching on fire. Furthermore, the lack of a built-in CO alarm makes us strongly recommend bringing along 1 or 2 detectors (preferably with a fire alarm combo) to be on the safe side. Lower oxygen levels at elevations above 7,000′ may also render the heater from working. Mr. Heater Buddy warms quickly and could sometimes get too hot even at the lowest level. A heater provides much comfort and can even be life saving. However, we do not use our Buddy continuously throughout the night as we prefer to only turn it on when somebody is awake and able to supervise. Call us paranoid, but we would rather be safe than sorry and owe our children our trust and protection. However you plan on using the heater, always keep safety in mind. With that said, Mr. Heater had become a luxury we would not go camping without when temperatures could dip as low as 28F! Be safe and stay warm! PROS - Can safely be used indoor when adequate airflow is provided and proper precautions have been made (see TIPS section) -- Tip-over sensor to immediately stop fuel when the heater falls over (you can hear the switch activating) -- Low-oxygen sensor -- Grid cage to keep flammable material (or your kids’ hands) from touching the heating elements CAUTION: Always leave a window or tent cracked open by at least 1″ (4 square inches) to allow for adequate air flow. Keep flammable material away from the heater. - Heats up very quickly -- Can get too hot even at the lowest setting -- Outputs 4,000 – 9,000 BTU --- Suitable for up to 225 sq ft, according to the manufacturer - Dedicated slot for holding a fuel canister -- Propane gas regulator swivels out to allow canister to screw on more easily - Uses standard 16oz/1 lb Propane Fuel Canisters -- Single tank can operate for 2.5 – 3 hours on maximum heat, the manufacturer claims, and up to 6 hours on minimum --- Mr. Heater provided this burn rate: 0.044 gal/hr @ 4,000 BTU and 0.099 gal/hr @ 9,000 BTU ---- Converts to: 5.632 oz/hr @ 4,000 BTU and 12.672 oz/hr @ 9,000 BTU ----- In other words, a 16oz canister can mathematically fuel for 2.84 hours on the lowest setting and 1.25 hrs at the highest ----- If my math is correct, that is half of the company’s run time claim. Maybe the provided burn rate is just a conservative estimate? --- Owners on the internet had claimed 3-5 hours of continuous use from a single 16oz canister ---- I did not run mine long enough to verify their claims as I do not use the heater continuously (see TIPS section) - Can be connected to larger propane cylinders via an optional hose assembly -- Mr. Heater strongly recommends their official 10′ Hose Assembly (#F273704) - Fold-down handle for carry or hanging CONS - No heater is 100% safe, Mr. Heater included -- Heat will always have a risk of fire. Burnt fuel will always come with a chance of carbon monoxide poisoning - May provide false sense of safety despite multiple protection mechanisms -- Tip-over sensor does not activate until past a certain angle. Could potentially leave heater running despite having tipped over --- Example: Heater falls over onto a mattress and remains propped up enough for the tip-over sensor not to shut off fuel -- Grid cage designed to keep heating elements from being touched is spaced too wide apart --- Piece of flammable material may potentially slip through and burn -- No built-in carbon monoxide (CO) alarm --- CO is odorless (cannot easily be smelled) and could unknowingly build up to deadly levels ---- Tip: Leave a window or tent cracked open by at least 1″ (4 square inches) to allow for enough air circulation. Bring 1 or 2 reliable CO detectors (ideally with fire alarm combo) and place them properly --- Propane could leak through a faulty regulator or optional hose attachment -- Low-oxygen sensor will NOT protect against CO poisoning --- Only detects low oxygen level and not how much CO is in the air - Heater may shut off at altitudes over 7,000′ above sea due to lower oxygen levels at that elevation - May not last all night on a single, 16oz/1 lb propane canister - Can get too hot even at the lowest setting - Bulky TIPS SAFETY It is absolutely important to take great care and proper precautions when using a fuel-burning heater. No heater is 100% safe. - Keep flammable material away from the heater -- I place Mr. Heater on top of a raised platform, like a small table, to keep things away --- Helps ensure the tip-over sensor shuts off the fuel if heater falls off. Note: heater is still hot when it trips over -- I had also bungee-corded the heater to one of the inside walls of a sturdy, plastic milk crate (open side facing up) that acted as an extra buffer against accidental kicks during sleep - Crack open the window or tent by at least 1″ (4 square inches) to ensure enough oxygen flow inside - Carbon Monoxide (CO) is odorless and can silently kill you -- Bring 1 or 2 reliable CO detectors (ideally with fire alarm combo). Do not solely rely on the built-in low-oxygen sensor as it does NOT detect CO --- Use fresh batteries and test the alarm --- Do not place them directly above or near the heater. I put one up on the tent ceiling and another in a side mesh pocket -- Check for gas leaks along the connectors and hoses with a leak detector or soapy water (look for bubbles) - If connecting Buddy to a propane cylinder via an optional hose assembly, Mr. Heater strongly recommends their official 10′ Hose Assembly (#F273704). No fuel filter is needed with it -- Third party hoses could improperly allow residue to backflow and damage the heater over time. Be sure to use a fuel filter with them MYTH: CARBON MONOXIDE HEAVIER THAN AIR? I had seen a few individuals claim that carbon monoxide (CO) is heavier than air and that sleeping on the ground while camping may leave you exposed to the deadly gas sinking onto you. As much as that sounds reasonable, both the Environmental Protection Agency (EPA) and Google Nest state that CO is actually “slightly lighter than air and diffuses evenly throughout the room.” In other words, CO rises, spreads, and does not entirely drop onto the floor. Nonetheless, bring 1 or 2 reliable CO detectors (ideally ones with a fire alarm combo) to be on the safe side. WE DO NOT HEAT WHILE SLEEPING Call us paranoid, especially my wife, despite having made all the safety precautions. There could always be a potential for something to go wrong while sleeping in confined spaces like a tent. As such, we generally do not leave the heater running while asleep. Here is what we do instead: - Turn on when we are ready to go to sleep. Makes the tent nice and toasty for the family, especially the kids - Before the last person goes to sleep, turn off Mr. Heater -- We set an alarm in case that person accidentally fell asleep - If it gets too cold again, turn on the heater for a few minutes until warm again, then shut off once more - Turn on when waking up so the family can get going to a nice and cozy tent As you can see, we only activate the heater when somebody is actually awake and able to supervise. The steps may seem like a lot of work, but we rarely ever had to get up in the middle of the night to reheat. The procedure had worked well for us and for many others — even in 30F temperatures! The extra peace of mind makes for a much more enjoyable, worriless camping experience. MR. HEATER MODELS/SIZES The model reviewed in this write-up, Mr. Heater Buddy MH9BX (F232000), outputs 4,000-9,000 BTU for 3-6 hours (according to the manufacturer) on a single 16oz/1 lb canister.

Good Buddies

I’ve been using these things since the ‘70s. I kept one in my VW Camper to keep warm in the winter nights. I’ve used them camping. They are simple and durable with no liquid fuel to worry about. Propane doesn’t spill and stinks if it leaks. Portable Buddy This is the second Portable I’ve purchased. The first was for my aforementioned ‘76 VW camper. This one is for our family inflatable 200sqft Koala 7 canvas tent. Yes, this little gem keeps things toasty in the evenings and overnight. I get about 100hours out of a 20lb tank. Good for about 4 days running on low 24hrs/day or 10 days just evenings and overnight for 10hrs/day. We do have a wood burning stove that we’ll use during the day should we have to if we’re in camp. But normally the days aren’t very cold where we camp in the winter, usually in the mid southeast. The wood stove is a nice ambiance, but the smoke is a problem if the air pressure outside is higher than the heated air inside. Hot air is less dense (it’s how hot air balloons float) and so lower air pressure per volume. If your stove draft isn’t strong enough to overpower the difference, you get a “back wash” of smoke. Cough, cough…. Big Buddy This has two ceramic elements, each is the same size as the portable buddy. Growing up in the northeast, we used the Big Buddy. With two elements, working independently (one lit is for Low and Medium settings and both for the high setting.) you get the benefit of the two units. If you need the heat of the portable Buddy, just use the Big guy on low and medium. If the temp is going to drop well below freezing, set it on high with both tiles glowing, for those times. The high setting flexibility is good to have, while the fuel and heat efficiency of the Portable Buddy “single” is the first option. Hoping your Buddy proves to be a good friend…. ... show more

Outside temp was hoovering around 30 degrees and was a bit cloudy. The heater worked flawlessly and kept the interior comfortable enough for a heavy shirt or sweater. My second time using the Mr. Buddy was on our winter trip February 20-22 2015. This is where I realized it was truly a great product. The Mr. Heater Portable Buddy was used in an 8 man Alaskan Guide Tent from Cabelas, the outside temp hit a low of -8°F. The heater worked well enough to warm the tent enough to sit in a light jacket. I was using refilled Propane Tanks, although I ordered the Mr. Buddy (NO FILTER REQUIRED) hose, Mr. Heater Buddy Series Hose Assembly - 10-ft., Model# F273704 we used the one pound propane bottles instead. I refilled a bunch using aMr. Heater F276172 Propane One Pound Tank Refill Adapter We had another heater, the Mr. Heater Big Buddy, Mr. Heater MH18B, Portable Propane Heater ITEM #: F274865 Model #: MH18B that we hooked to a 30 pound propane tank. Between these two heaters the "Portable Buddy" on low at 4,000 Btu's and the "Big Buddy" on medium at 9,000 Btu's the tent stayed toasty warm all weekend. We even took the "Portable Buddy" to a portapotti and heated the portapotti up to, "Do the 2". I felt comfortable leaving both of these heaters on when we slept, in fact we were stuck in the tent from Friday afternoon till Sunday morning and these were never shut off, we also ran a propane lantern on low at night and used a Camp Chef Everest High Output 2 Burner Stove for hot beverages and cooking. We had a carbon monoxide detector in the tent and it never once beeped, even after frying some porterhouse steaks and as load of potatoes. The Mr. Buddy Series heaters make no sound at all, has zero smell, are easy to use and are incredibly efficient. The piezo ignition works well, but I want to point out one thing, if the heater is pitched back slightly, the pilot will not light the propane , this is due to the angle of the ceramic, just make sure its on a flat surface. I would just tilt the heater slightly forward to ignite the propane. Tanks screw in with a little push to push through the seal in the propane, the fact that the connection swivels out makes changing out tanks easy. ... show more

Works well, appears to be a quality item
Color: Red
Right out of box had it running in a couple minutes. Very handy, easy to store and cranks the heat out. The tip over shut off I tested worked, can't test the O2 sensor. I noticed no odor when starting or turning off. I plan on using it in an RV for spot heating so I dont' have to fill up the main tank. I will leave a vent cracked just in case. Two wishes, a timer and a remote off switch. It would be perfect then. EDITED TO ADD SOME INFORMATION I had ordered this early knowing I was going to need it within a month or so. After checking it out and making sure I knew how to use it, I shut it down, remove the tank and stored the heater in my little RV on a kitchen shelf. Last Friday night I was in the area I was having to overnight for an early morning call. I buttoned the RV up, pulled out the heater, installed the can, hit the pilot button and after 30 second released it. It shut off. So I did it again, then again and then again. I got a spare new tank out and put it on and tried it again and again. Long story short I spent the night in a 17 degree RV because the heater with a total run time of 10 minutes would not work. Today I finally got in touch with Mr. Heater and after dealing with their awful phone system left a message asking someone to call. About an hour later Kyle called and I explained what had happened. I told him I had cleaned the pilot light as they suggest and nothing worked. While speaking with him he asked how I had stored the heater. I replied on it's back on a shelf. Bingo, there's the problem. He tells me how to take the back off and disconnect two wires from the tipover sensor, jump them together with a paperclip and then I was able to immediatley start the heater and it worked as it should . Apparently storing them on their back may cause the tipover to stick and not release when the heater is put upright. He i sending me a new sensor which I may or may not put in. So 2 important things, don't store this on it's back and if your pilot lights well but the unit itself won't work, open up the back, remove the wires from the little black part mounted to the bottom, jump them with a paperclip and see if it will start. Bet it does. ... show more
