    • Love my Portable Buddy!
Color: Red Style: Heater
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

    • Great heater
Color: Red Style: Heater
This heater arrived on time and was packaged well. It's sturdy and works exactly as it should. It's easy to use and surprisingly light weight. The tip over feature is great especially around kids and dogs.

    • Does its job very well
Color: Red Style: Heater
This propane heater does its job beautifully. It is not large, but it puts out quite a bit of heat, more than you would probably need in a tent, camper, or bedroom. Be careful and have a window cracked a little bit for ventilation, but this should keep you toasty warm. I am not much of a camper, but I bought it for times when our electricity goes out in the winter. We had one spell a few years ago when we lost electricity from about 7 in the morning until 4:30 in the afternoon. The temperatures were well below freezing, and we had nothing. The last couple of hours my wife and I crawled under the covers and tried to nap. But now with this heater and a few propane bottles, we can at least heat one room and stay toasty warm. ... show more

The media could not be loaded. 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.
