I purchased the Big Buddy heater in October 2011 as an emergency heater (we were in the early part of a snowstorm-induced 5 day power/heat outage). It works with those disposable 1lb propane tanks; I also purchased the quick-connect hose adapter to allow me to connect it to a standard "grill sized" 20lb propane tank (http://www.amazon.com/gp/product/B000UC7966) I used this heater for indoor emergency heat during that October 2011 outage, and again this year during the aftermath of Hurricane Sandy, when we were without power / heat for two weeks (and again, treated to a snowstorm). Have not used this heater for regularly heating my home, or for any other purpose such as heating a garage, heating any outdoor area, etc. So my review is based on use as a residential heating appliance in emergency situations. In my experience, this heater performs very well, and I can't think of anything that I think needs to be changed or improved. It's lightweight, portable, and reliable. It puts out a good amount of heat, and functions well as a room heater in our old, drafty house. I did not detect any odor or fumes when using the heater. Nonetheless, as with any non-vented combustible heater, one must be careful because ALL such heaters will output carbon monoxide, and you need to make sure you have a carbon monoxide detector in the room you will be using it. I prefer to use this heater with the 1lb disposable propane bottles (the heater uses two of them at a time). It makes the heater much more portable. But more importantly, I have come to understand that it is very dangerous to bring a 20lb propane tank indoors, because of the risk of leakage (propane is a gas that is heavier than air, and it will invisibly pool on the floor and could ignite if it encounters a source of ignition, such as a gas stove pilot light, or a furnace pilot light, etc.) I had never realized the lingering danger that propane presents to indoor use. Outside, or in certain indoor locations that have lots of venhilation, such as barns, sheds, etc., you can count on the fact that the propane will dissipate before it becomes a danger; the same is not true in most residential houses. In truth, even a 1lb bottle of propane can be a risk indoors, it's just a lesser risk due to the lesser amount of potential leakage. It's no fault of the heater, it's just a fact with propane as a fuel source, and one must really understand this when making decisions about these types of heaters. By contrast, with something like a kerosene heater, you sometimes hear comments about how it might smell (I think mostly this is due to either a faulty or old heater, or improper operation/maintenance). But at least with kerosene, it will not give off vapors that can spontaneously ignite and explode, and you can be pretty sure that, so long as you are following proper procedure and refueling outdoors when the heater is cool etc., it's not going to explode on you. Propane is, in my opinion, a more dangerous indoor fuel, because you are at possible risk of mechanical failures (e.g. leaking valves on even the 1lb propane bottles, or some internal leak in the heater). I would not run either a propane or a kerosene heater at night while I'm sleeping. Anyway, taking into consideration the above points about propane, the Big Buddy heater does what it's supposed to do, and does it very well. With two 1lb bottles of propane attached, we could use it to heat up the kitchen in the AM to take the chill off, have breakfast, and get the kids dressed. Then I would turn off the heater, store it outside (just in case it started leaking), and bring it back inside in the evenings to use for a few hours when the house started getting cold after the sun went down, to eat dinner and get the kids ready for bed. I would run it mostly on high or medium, and that's enough to heat a large room in our drafty old house. Using the heater in this manner, I would burn two 1 lb bottles per day. As a short term fuel, the 1lb bottles are great. But as a longer-term fuel source, it would be expensive. I do have the connector hose to connect it to the 20lb tank, which works great and I have done that a few times (leaving the 20 lb tank outside on the porch and leaving the door open a crack to allow the hose into the house to connect to the heater). But the more I learned about propane, the more hesitant I became about using it like this, even with the tank outside. My concern is a leak somewhere along the rubber hose, or again, maybe somewhere within the heater, and connected to a 20lb tank that could dump a lot of propane inside the house that could ignite if it lingers and finds a source of ignition. I wouldn't hesitate to use this heater outdoors or in any of those garage/barn type of situations, where it would be great and you wouldn't have the same concerns about leaking propane. I'm giving this 5 stars because I do think this heater performs great for its intended purpose. It's far superior to a kerosene heater in terms of its portability and transport for things like outdoor sporting activities, etc. It's clean (as clean as it can be anyway), reliable heat. But I wrote all of the concerns I had about the fuel source generally, so that one could make an informed purchase decision. For an emergency home heater, I also picked up a kerosene heater. It's good to have two options, as fuel can be difficult to find (as I found out during our 2 week outage!) and those of us without a lot of outdoor storage space would have difficulty safely storing enough propane (I don't have a garage or shed, where I would preferably store the propane, so I keep it in one of those weatherproof plastic outdoor boxes you can buy for gardens supplies etc.).

With the now hundreds of reviews for this item, what can I say that has not already been published about this heater? I have few things. First, I also own the Portable Buddy and while it is a good heater, it has its draw backs. The first thing I like better in comparison is the control knob of the Big Buddy, it's very smooth and ignites readily, it's also responsive and seems like it is better quality than the Portable Buddy unit. The handle is solid and does not fold down. The legs of the unit are soft rubber and non-adjustable. For a heater this size (I actually did gasp when I first got it, compared to the Little buddy) I think it would have been a plus. Having spoke about the legs, they are very soft and should play nice on wood floors. The unit is not very heavy and is easily carried with its sturdy handle. I'll say the fan is more gimmick than functional, but it does help throw out the heat to a degree. Do not expect blower style air out of the fan, it can run off of D cell batteries or an adapter that is sold separately (I wish I had sprung for the adaptor). I did spring for the quick connect propane hose by Mr. Heater for hooking up 20-40lb propane cylinders. If you buy the regulated quick connect hose you DO NOT have to buy the filters for running bulk propane. This is a money saver in the long run and worth it. The regulator inlet for the quick connect is located next to one of the inlets (opposite side of the control knob) for 1lb bottles and is easily accessible. This heater can be hooked up to (2) bulk propane tanks at the same time using connection hoses for bulk propane 20lb cylinders adapted to the 1lb connector or (1) 20lb bulk tank using the quick connect hose (to clarify for absolute clarity it only has (1) quick connect inlet and has an additional (2) propane inlets that are fitted for 1lb bottles. You may also run (1) or (2) 1lb propane bottles at the same time. The heater does well on the LOW settings and MEDIUM settings, the second element does not light until you turn it to HIGH setting. It does not matter what side you hook up propane to or in what manner you hook it up, the heater will run normally and work on all of its temperature settings (yes this was brought up in other reviews and is a source of confusion). The heater puts out a lot of heat on the HIGH settings and other reviews of the 1lb bottles freezing up on HIGH settings are more than likely accurate. This is no fault to the heater, it's just that on HIGH this thing eats up a good bit of propane and over a period of time empties those 1lb bottles more quickly, thus the moving gas freezes up the bottle. In a warm room this phenomenon may not occur and I'm not saying it always will, just don't be surprised if they do freeze under certain conditions. The Heater will NOT freeze a bulk tank 20lb or higher, I know this for a fact, I've tried. Durability wise the heater is a well built unit that has been running every night of the week in my garage for the last 5 weeks, and there's not been a single hiccup. my Portable Buddy has been put through hell and still runs like a champ, this one should be no different. The safety shut off Is very sensitive and at the first sign of tipping it shuts the heater down, I think this is an excellent feature. There is no smell with this heater, it puts off pure heat with no weird odors. The connections seem machined well and I have never had a problem using my Mr. heater hoses. The instruction manual is well layed out and tells it like it is, if you cannot understand this manual then you should not be using the heater, it's that easy. For the price range, features, durability, safety features and portability it is a no brainer purchase. The heater feels well made and puts out a good bit of heat. I use mine consistently for long stretches at a time and it works without issue. In an emergency situation I would trust it. If it were stolen, I would be sad and then buy another one. I hope this helps in your decision. Cheers!

Arrived on a timely basis, well packaged. Set up immediately. 1 lb. Propane. It was fairly easy. Once I realized The input would turn to make this an easy process. I did experience an issue with the electronic start. I had inserted the battery and all seemed well but would not function. I called customer service and was very pleased with quick response. The problem with the electronic ignition was a user error. I had installed the battery with the negative toward the spring on the cap. Come to find out it goes in the other way. Once the change was made I immediately had electronic ignition. I set this up in my shop and it is pretty cold here. Set on high and it began to heat quickly. As with many others, The built-in fan is pretty weak in distributing. I will be setting up another fan behind to direct the air flow better. The manual leaved a bit to be desired. It certainly covers all potential hazards and I'm sure is very helpful to first-time propane users. The manual should have explained about installing electronic battery. Second, there was no indication as to whether it required a c or d battery for the fan. Just looking at it. I figured it was D. That worked. The other issue is to describe plug needed for the fan if someone does not want to use the batteries. I am in the process of preparing to hook up a 20 lb bottle and only used the 1 lb to test out the efficacy of The heater. At this time, I can say I am pleased with it Update. One of The regulators for the 1 lb propane bottles was bad. A machining issue. I contacted Mr. Buddy heater and they indicated to return the item or go through Amazon. I chose to go through Amazon and return the item without any problem and 3 days later had the new one. The new one does not have this issue. I can only say that between Mr. Buddy heater and Amazon. I am now satisfied. The new one has no issue with either one of the regulators. I can say that it has heated up my shop very quickly to a comfortable temperature.

Had a lot of unusually cold weather this year and this heater saved the day keeping me warm. Expensive to operate but keeping warm makes the cost worth while.

Alright, I've never left a review for a product before but I feel it is my responsibility to set some things straight. 1) 20 lbs propane tanks. Any and all complaints related to the use of a 20 lbs cylinder (leaky valves, clogged filters, shutting down, fumes, regulator freezing, and more) are from people who don't read instructions. The owners manual, which you can view on the Mr. Heater website ([...]as of 03/27/13), clearly lists the appropriate hose and filter part #'s on page E-3 and E-4. I have had zero issues with the hose I bought through Amazon: hose no. F271803, using an "adapter" or any hose not listed in the owners manual will cause issues. 2) Cold weather use/ Use at higher elevations I use this heater to warm up my WilderNest Camper when I go camping in the winter. I have used it at elevations ranging from ~4,500-10,000 feet. I have spent many a winter's night camping anywhere from Crested Butte, CO, to Canyonlands NP, Utah, with temps ranging from the low 20s to -10 F. The -10 trip was this past February in Crested Butte. On that trip, as with all others, within minutes of firing up the heater I was able to take off my hat and gloves; by the time my coffee water was boiling I had no need for my jacket, and by the time I drank my coffee I was too hot and stripped down to t-shirt and shorts... in February, in Crested Butte, at 9000ft. Also, I've read complaints regarding the pilot flame not starting. The instructions state that you need to allow the pilot flame time to get to temperature before firing up the ceramic heat plates. I use a BBQ lighter to torch the pilot lighter to start it and get it warm faster. Once warm (~30 seconds), the thing is rock solid. 3) Shutting off issues My Heater never shuts off unless I move it and trigger its safety mechanism. Every time it has shut off automatically it has been completely expected (because I was moving it) and restarting it takes about 2 seconds (since the thing is now pre-heated). I've never had issues with the pilot flame blowing out, as some people complain, and have even tested it out by blowing on it. If you are in a situation where the pilot flame can be put out, then you're probably also in a situation where the wind will just blow your heat away anyways. 4)Period of consistent use I remember some commenters complain that their heater turns off after a couple hours of operation. I've never had that happen, not once. I have used my heater continuously through the night with zero issues (other than that sometimes I have to turn the thing to medium or low because I'm getting too hot). 5) Fuel use This thing has high BTUs and that means it does drink its fair share. If you intend to use this heater for long periods of time you must use a 20 lb gas cylinder. If you are looking to heat up weekenders, or week long trips then you will be happy. I've now switched back to using two 1 lb gas cylinders (I'd rather not deal with hoses and big tanks unless I have to) and only use them to heat up before and after bed (I heat it up to about 70F on high). With this method I can go comfortably camping when it's zero degrees for a week without running out of fuel. I remember being exactly where you are now. "Is it worth it to spend that much? Ugh, look at these bad reviews, but some people really like it; how am I supposed to decided?" Well, I'd note that the positive reviews out number the negative, and I think people generally leave reviews when they are unhappy, so... that's a good sign. I'm as happy as I could be with my heater and I, as well as my buddies, consider it essential to enjoying winter camping when its miserable outside. good luck

Bought this to heat my 2 car attached garage in the winter. When it gets REALLY cold outside IE: 10 F' my garage gets to about 34 F'. Which in the winter time sucks when working on the cars. I have been using electric radiator type oil heaters and those are nice but don't get hot enough plus the electric bill goes up because I have to have them on hours before even starting work. I was very skeptical of this. Propane heater in the garage, carbon monoxide...etc. Just seemed like a really big hazard to me. Tried it last night. I'm really impressed by it! On low/med it puts out a lot of heat. On high it puts out a TON of heat. I was actually not expecting this at all. I purchased two things separately which I think are important if you are going to use this in a garage type of space. One was the 10' regulated quick disconnect hose. 12ft Big Buddy Hose with Regulator I also purchased the power adapter but not the OEM one which from all the reviews is a piece of crap. I bought this one: [UL LISTED] Pwr+ Extra Long 6.5 Ft Cord Mr. Heater Optional 6Volt Power Adapter for Big Buddy Heater Mh18b F276127 F274800 Cord Propane Heater Ac Adapter Charger Power Supply It seems to move a lot of air with the fan on. I can't help but wonder why they didn't use a different fan. At only 6v this fan makes more noise than my 12v fans in my computers that I build... I will at a later time probably replace the fan in the unit with something better/quieter. As it sits now the fan is probably a pos one. On the low heat setting this unit makes a little noise. On medium and high heat setting it's almost silent. I like that it has two holes on the back so you can hang this on the wall. I plan on doing so and then having the hose and propane tank down away from the unit. Having never owned one of these units before I was surprised at how easy it is to use. If using a remote line you have to prime it to purge the air out of the line until propane comes through. This took about 1 minute for me before it would light. When I started to smell a small amount of propane I attempted to light it and it was fine. Note that when this is on I do NOT smell any gas or foul smells. (unlike kerosene) I dislike how bulky this unit is. I really feel they could have slimmed it down somewhat because when you look in the housing there is a lot of dead space in it. OR have a version that is strictly used with a remote line to discard the two on board tank holders. I will come back and edit the review if anything changes but I can't wait for it to get cold now to really use it. I can then update on hours I get from a 20lb propane tank.

Used 20 pound cylinder, 12 foot hose with regulator with MH (Mr Heat). Plugged in 6 volt AC adapter with no batteries inserted. Pressurized line with propane and waited 2 minutes. Turned red valve to PILOT and pushed down for 2 minuets. Let up valve and activated piezo sparker. Pilot flame ignites on first try! Kept red knob pressed down for 2 minuets to heat up thermocoupler and then turned red knob valve to medium to let left ceramic ignite. Then turned red knob to high and both ceramics ignited to bright orange. Fan worked great! Forgot to leave MH on and turn off propane tank to bleed off propane in line. Just turned off MH red valve, then shut off propane valve. Last goof up was storing propane tank hooked up to MH in my shed. So today, I will go out to shed, disconnect MH from propane tank. Then store the propane tank in my tarpauline shed, which is pretty much open to the air. But leave MH locked up in my secure shed. Never bought the fuel filter and film clips say I should, but MH documentation says a fuel filter is not needed with a regulator installed on the hose. The reason the fuel filter was recommended was possible contaminates from the propane tank. Because the regulator reduces the psi to about 50 psi, this stops the oil seepage from the propane hose. So the main reason for the MH fuel filter is strictly related to propane tank contaminants getting into MH. Ok, I bought the 12 foot hose with regulator AND THE QUICK CONNECTOR. Therefore, I do not think I can screw on a fuel filter even if I wanted to. ANY OPINIONS OR RECOMMENDATIONS?? It says under MH will get hot, so I guess I will purchase a heat protector for under the stove. I bought MH for our dining tent that zips right up tight, so I will have to make sure I drop a flap so I get about a 5" X 5" air draft coming into our tent. I was going to use MH at night too while my son slept in the dining tent, but will not after reading the safety instructions. There is a special zipper slot at one bottom corner of the dining tent to run a hydro line or/ and propane line into the dining tent. Therefore, the propane tank can be left outside of the dining tent. Because we will be way out in the country camping, I will take along a spare 20 pound tank to have on reserve. But it does sound like we may get quite a few hours out of one 20 pound tank. I am getting our RV dealer to install a propane line in my RV with a quick connector on the end. Then I will construct an adapter location in our RV so we can mount MH on the wall. I have 30" above and in front of MH for the location of the install. It does seem MH is quite safe from carbon monoxide from testing I observed on line on a YouTube clip. But our trailer does have a CO detector anyway. Overall, I am really impressed with MH Big Buddy. I read everything and reviewed all online film clips on You Tube - excellent unit and recommendations! I also read every review on this unit with AMAZON.com and as long as you are careful following the directions, it is a safe and reliable unit that will last you for many years with proper care and maintenance. Oh and great at home for an emergency back up heating source too!

This thing is great. Let me count the ways..... 1. It is friggin hot and fast. I rarely use central heat, and, as such, my house can be in the 50's during the winter. On high, this usually gets my "game room" of about 450 sq. feet to "sweating level" in 15-20 minutes. Put it on low and keep the door shut and it'll keep the room nice and warm. It heats up my master bedroom MUCH faster than a 1500 watt space heater (http://www.amazon.com/gp/product/B002Q4EYEQ?psc=1&redirect=true&ref_=oh_aui_search_detailpage) and it's half the size. 2. Portable. It's not the smallest thing in the world but it's certainly portable. It's saved me on some deceptively cold camping trips, and I will grab it on the cold mornings (if it's in another room) and put it next to the shower for a comfortable exit. Your portability is obviously going to be negated if you have it attached to a 20 lb. canister. 3. Safe (thus far). If you'd read bullet 1 and 2 you'd know I wouldn't be around to write this review if it weren't safe for indoor use. I've put a carbon monoxide detector in the room while the heater was in use, just for fun, and it never rises above normal levels. I've forgotten to turn it off after some of those cold morning showers and left it in my bathroom to burn out. House is still intact. It's VERY difficult to move it (while it's on) without engaging the safety cut-off feature. So it'd be impossible to knock it over and have it continue running. With the grated covering you'll be protected from all but the most determined attempts at destruction. 4. Relatively efficient. If you're concerned about power outages you obviously aren't going to rely on a space heater to keep you warm in those times. Electric heaters are ridiculously power hungry especially if you have a wattage concern (as in a power outage). I have a 300 AH/300 Watt small solar system and I'd never consider running an electric heater during outages. Only a generator would suffice and even then you're talking about 1 appliance eating 50 percent or more of a typical output. Propane (unlike gas) has an indefinite shelf life and a 20lb tank could run this for 30 or 40 hours on high. I only use 20 lb tanks if I know it'll be running for awhile. I get through an Alabama winter on 12-16 1 pound tanks. At ~5 bucks for 2 you're looking at roughly the same expense as 3 hours/day/3 months with an electric heater. So while an electric heater may be more convenient and aesthetically pleasing, this guy dominates for uses like power outages, quick "spot heating" (ie. bathroom), and camping. Gripes. The 4 D batteries for the fan/blower seems super excessive to me. It really doesn't even blow that well and I never use it. It doesn't add much in my opinion. If you're in an enclosed room, the heat will get to you anyhow. If you do use it, you'll probably forget to turn it off and kill the batteries in one sitting (as it's a completely separate switch/mechanism from the "fire"). D batteries aren't the cheapest thing in the world. The side compartments are a little tricky to get open sometimes. It's tough to screw in the small canisters to the inputs unless you're at a perfect angle. It doesn't seem like It fully burns the small canisters. Every time it runs out, I'll see the fire flicker, go out, and then smell propane for a few minutes. TIPS/Hints Get a filter hose if you intend to use 20 lb tanks. Use both inputs if you're using small canisters. The runtime would be aggravatingly short with only 1 canister. Usually, a flickering, uneven, and noisy flame means you're running low on propane. If you run out your tank it's going to be icy/cold.. that's just physics. Overall this is an amazing product which is very versatile and useful in lots of situations. Would certainly buy again or recommend to anyone.
