  • 30,000 BTU BLUE FLAME CONVECTION HEAT - UP TO 750 SQ. FT.: The clean-burning blue flame tube burner uses natural convection to circulate warm air evenly throughout spaces up to 750 sq. ft. without hot and cold spots common to radiant heaters. 27.25inW x 11.25inD x 27.0inH
  • NO ELECTRICITY AND NO OUTDOOR VENTING REQUIRED: Runs entirely on liquid propane with no electrical connection and no exterior vent required, making it ideal for garages, cabins, workshops, and supplemental heating in any room with propane access.
  • ODS LOW OXYGEN AUTOMATIC SAFETY SHUT-OFF SYSTEM: The factory-installed Oxygen Depletion Sensor (ODS) automatically shuts the heater off if oxygen levels in the room drop below a safe threshold, providing a critical layer of protection during operation.
  • ON-BOARD THERMOSTAT FOR AUTOMATIC TEMPERATURE CONTROL: The integrated thermostat cycles the heater on and off automatically to maintain a consistent room temperature, reducing fuel consumption compared to running the heater at a fixed output continuously.

So Far, So Good
Style: Heater
Review Image by El mzungu
I have only had this up and running for a little over a week, but it's been really cold, so it's been a great test of what it can do. It's replacing a 60,000 BTU vented heat stove that's around 65 years old. When I saw the square footage that that is listed as it's effective limit, I was a little skeptical about its ability to heat my whole house where temps often fall below zero for about three months each winter. I got the optional blower, but it's not strong enough to distribute the heat very far. It's still worthwhile, because it blows the rising column of heat far enough to place a more powerful fan just above the heater without it getting hot. That fan, aimed upwards at about 30°, redirects the rising heat wherever it's pointed, and even keeps adjoining rooms comfortable. It's gotten down to 0 and below the last two nights, and the heater hasn't been set above 2 either night. It was even a little warmer than I wanted when set at 2, so last night was about 1 1/2. One difference from the old heater that takes some getting used to is the way it regulates the heat output. The old units on/off cycles were much longer. The flame would stay on for several minutes (depending on where the thermostat was set), and then they'd go off for a while. This unit can cycle on and off a couple times in about a minute. Not that it's bad, just different; sort of like it micromanages the output. After such a short while, I obviously can't rate it durability, but it seems sturdy enough. The little assembly involved in attaching the feet was quick and easy, but I let a pro hook it up. He had to tie into the existing line and run an extension about 7 feet. Mainly, he had the stuff and experience to check for any leaks properly. I probably could have done it all pretty easily, but I feel better knowing it's all done properly by a guy I have known for a long time. If you're debating getting a primary heater and wonder if this will be enough, it will easily handle more than the 1,000 square feet listed. ... show more

Great heater for a great price - updated 2Dec2019
Style: Heater
I bought one of these for my wood working shop (13' x 29'). It easily heats this shop and allows me to work all year long. Here are a few comments from my experience and to answer some questions that have been raised: 1) A wood shop is a high dust environment. Good dust collection is essential. Even then, I frequently use an air hose and blow off all dust on the heater (and as much inside as I can reach with the nozzle) before I start it up. Update: after 2 years of use (off and on depending on what projects I have going), it started taking longer and longer to ignite the pilot light. As they say, "when all else fails read the documentation". I read the trouble shooting section and it suggested cleaning the nozzle. I had to take off the front grill. I blew compressed air thru the side hole in the nozzle and a bunch of sawdust came out. After that, the unit started lighting up right away again. 2) My shop is very well insulated. I crack open 2 windows an inch or two to make sure there is enough oxygen for the heater. I may come back later and put in air flow vents. However, cracking the windows works just fine and I can close them when I'm not using the heater. 3) I live at 9000' elevation in Colorado. It works just fine at this elevation (see #2). 4) Follow all the recommended safety rules including locating the LP tank outside of the room. I put a 100 lb. tank on the other side of the wall from the heater in a barn. It is well insulated. I included a shutoff valve and condensation collector per code. 5) The lowest setting on the temp control (#1) sometimes keeps the shop at 68 degrees. However, at other times it heats it up to about 64 degrees. I don't know why it varies like this. I would really prefer being able to keep the temp around 65 degrees. I wonder what kicking the control all the way up to "5" would do? 6) This unit is made with very thin sheet metal. It really doesn't give you the best feel for a really well-made, quality product. However, it does what it's supposed to do and I haven't yet had any trouble with it. I used this at first with the provided feet until I was sure it would meet my needs. Then I mounted it on the wall. 7) Last, but not least, you can't beat the price! ... show more

It is going to cost you
Style: Heater
Like a boat or a RV this is an expensive hobby. This thing is going to cost you about $200 to buy. A little less when it is warm & a little bit more when it is cold. But you have not even begun to spend. It comes with nothing to make it work. You still need fittings. a hose, a tank, a regulator, propane, you get the idea. So now you are out about $400 (yes that $200 is going to double before you are done). Mr. Heater has a kit for about $55 that has the hose, fittings & 2 stage regulator. You should get some kind of coupon code or something if you bought the heater. Nope cha-ching $255 & counting..... Wait you need propane, big box store here we come. You don't have a trade in. So the first tank is going to cost you $65 around here. There are the little things but I don't want to count pennies. It is now you realize it is the PRINTER/INK SCAM!!! You are going to connect it to the tank & LOVE IT!!! It is everything the good reviews say it is. Like easy to setup, to light, to operate. The blue flame is easy on the eyes. Be warned propane burns blue with clean air. It is going to burn an orange/yellow if you are going to kick up any dust. Do not panic if you have a humidifier going. Turn this on and it is burning yellow. It is not malfunctioning. It is just burning the minerals in the air. The heater itself is not ugly. For the next couple of days you are going to love it. It is so nice to look at & so nice and warm (of course it is only 66 degrees outside but you ignore that). You are ready to start bragging & POOF you need more propane. Hmmm that was only 3 days of mild use. You ignore that too. You have a trade in so now it is only $30 bucks. Now it drops into the 40's & POOF!!!! This is getting annoying. So another $30... what are we at now $380. As you ask around you find out those 20 pound tanks are only filled to 15 pounds. You need your own tank. One that you don't need a truck to own. One that is not to heavy to lift/carry. 30 Pounds is the way to go. It is 2 of the trade ins yet cost less to fill then one trade. So another $100 and it gets into the 20's outside. Wait a second this thing is not as warm as it was (when it was 66 outside & you still have not researched BTU's). Can it heat 750 square feet when it is 66 degrees? Yes, as long as it does not get any lower. The lower the temp, the lower the square footage. If you drop the temp from 66 to 26 then your square footage will be about 250 sq ft..... With a 30 degree bump. To bring that 26 up to 56 @30,000 BTU's (30 degree bump) is going to shrink it to 250 sq ft. It will already be running non stop. To get it warmer, you need to shrink the square footage even more. Wow but owning your own 30 pound tank sure made things better. Yes you ignored things and are out $500 but it is finally over. It does have the flaws of the bad reviews as well. It needs glass or something. It is to easy for anything to contact open flames. When set to 1 it makes real weird sounds like it is getting ready to take off on a runway. No matter the setting there is going to be that whoosh of flames @ ignition. Who cares it is yours. You are out working in your detached garage. There is a heavy snow falling outside the window with gusting winds. You are staring at the blue flames being warm as this little heater tries to battle a PLANET. You just sit back and enjoy & POOF!!!!! ... show more

Great quality, works well and no smell.
Style: Heater
We love these. No smell, our carbon monoxide detector has never gone off. Automatically turns on and off based on dial adjustment. Super Easy to install. We purchased the hose attachments for this model from them. We didn’t buy the fan attachment and will do so this fall. We keep it on low after we’ve taken the chill off to help conserve propane usage as needed. If you need heat in a room big or small these are great. And a fair price! ... show more

Don't listen to the critics! Just don't use the Elbow and buy the Kit
Style: Heater
1. Mr. Heater Corporation F299730,30,000 BTU Vent Free Blue Flame Propane Heater, MHVFB30LPT 2. Camco Low Pressure Gas Regulator with 6' Hose 7000 BTUs/Hr Simple and Quick Install - Use with Low Pressure Gas Fired Heaters (57703) 3. Mr. Heater One-Stop Universal Gas-Appliance Hook-Up Kit 4. Order a 1/2 female to 3/8 male flare fitting if you plan to use the cutoff valve in the kit. Okay, I just purchased this heater and I can't be more pleased with my decision. I read the reviews and many of the negative things you're reading is because people purchased without reading first. Just like a previous reviewer stated about the elbow that comes with the heater -- DON'T USE IT PERIOD!!! DON'T ATTEMPT IT AT ALL! Just buy the Mr. Heater One-Stop Universal Gas-Appliance Hook-Up Kit -- Now with this I used everything but one 1/2 male pipe to 1/2 female flare because it wouldn't fit onto the Camco low pressure gas regulator I purchased because its 3/8 (So you need to go to home depot and buy a 1/2 female pipe to 3/8 male flare and probably more plumbers tape because its not enough in the kit. That's all you need to get this working. Absolutely, no need to wait months for parts that is just ridiculous!!!! Home depot has everything you need or your nearest plumbing supply store to get this connected. I don't believe anyone would buy this product then wait months for parts to arrive. Just doesn't make sense when you can get them locally. Now to address the cutting off part when operating this is normal -- and the heater with cut on/off while operating which is awesome because you don't have to continue to adjust the setting. It goes from blue flame to pilot then back on in intervals, so this is what people is referring to then they said it comes with a thermostat. Nothing you will see on the product it just does it automatically and is a nice feature that will save on propane. Next, I seen people complain about the smell of that comes with this heater, but I can truly say I don't smell any odor and I haven't had to open any windows yet. I do have a Kidde fire alarm with a CO2 detector this sits in the same room about 5 feet away and it hasn't triggered. It doesn't make you sick and dizzy these comments are misleading. Blower fan: The fan isn't needed at all so don't waste your money buying it. I would address more but just listen to what people already told others and this product will work fine and you won't be disappointed. Don't reinvent the wheel if someone already tried the elbow and it failed. Don't continue to use it because you think you have the magic touch. ... show more

Great job, Mr. Heater!
Style: Heater
The focus of this review is on the high quality of Mr. Heater. A comment is shared at the end regarding the unsafe lack of suitable packaging, which is a critical concern for potential Amazon consumers of this and other such products. The heater is awesome. It produces heat for about 8,000-10,000 CUBIC feet. The controls work perfectly. The safety features are comforting. The cabinet is solid and the safety cover is well-designed and firmly integrated into the heater. The appearance says “I am efficient” and as the unit is compact, it takes up the space of an average living room chair on the floor or can be mounted on a wall safely. I’d argue having the unit on the floor makes more sense if you have the choice. It’s not a warm and cozy look like some MUCH more expensive units with their facades and fancies, but sprawling on the floor in front of this heater is still a great place for a winter’s nap! I think the feet on this heater are especially well-designed. Reflecting those of an animal’s cloven hooves, Mr. Heater will stand firmly and yet not obtrusively. They comport well with the design motif of the appliance and speak well of the design approach taken by the manufacturer. I believe that a better choice of color for the screws in the frame of the unit would be to match the cream vanilla color, but silver screws were used. This truly is the only thing about the heater with which I find fault. Unfortunately, I recommend that you DO NOT order such items from Amazon because they insist on shipping them in retail packaging and you will likely end up with a damaged unit as we did. Twice. I love just about everything else about Amazon, but this practice poses a safety hazard with such products and is super-frustrating in general. ... show more

Guys read the instructions or have your wife help.
Style: Heater
When I 1st got this unit I hooked it up to a 20# tank and had the legs on as I wanted to see how it would work before I wall mounted it. Worked as I was hoping it too. Primed the lines and fired right up. No propane smell and a lot of heat. Read and reread instructions (which I seldom do as I'm a guy ya know) and went and picked up the hardware I would need for wall mounting. I was tapping into my 120 lb tank outside my house , so I needed copper tubing , a tee fitting and a couple other thing to do the job right. After new line and all hooked up and heater installed to the wall (yes I double checked for any leaks ) I primed the line and on came the pilot light and then the main burner. I set it to lower settings 1st , then set it to high. The heat was amazing. After app 3-5 min heater would shut down then in 3-5 min come back on. I 1st figured this was how it was suppose to run. After 4-5 days I was over to a friends house and he had the same model and I checked it out. Like I said I'm a guy and sort of read the instructions. Went home and installed the 2 round spacers which goes behind the 2 bottom mounting screws (2min job). This allows the thermos to work as it should. Bottom line is this is a great heater , NO SMELL and a lot of heat. ... show more
