This is a great portable heater. I converted my garage into an office @ 24x25 and it does the trick of keeping the temperature 65 this winter. Per other reviews, yes, the fan could be more powerful, but it works. Purchase the power adapter for the fan's operation. The D's work, you'll run thru them. Great construction, and functional.

The Mr. Heater 18,000 BTU Big Buddy Pro Series Portable Propane Heater is a reliable and efficient way to heat larger spaces like garages, workshops, or outdoor areas. It’s easy to set up, works with small propane cylinders or larger tanks, and has great safety features like a low-oxygen shut-off and tip-over protection.It heats quickly and runs quietly, making it convenient for both work and relaxation. Just ensure proper ventilation when using indoors and be prepared for higher propane usage on high settings. Overall, it’s sturdy, effective, and a great choice for reliable warmth.

Great heater but the igniter does not work at all. Heater works fine but you have to light the pilot with a lighter !!!!

Used this in my cabin with the fam this year in the winter when the furnace was in repair. Holy smokes it really heats the place up. This type with the built in fan is a must. It is slightly bigger than the other versions. For a tent you could get away with the small version. I purchased the attachement to use a full size propane tank. Works excellent. Again the built in fan is a lifesaver. I also purchased a carry case for the heater and a carry case for my large propane tank on amazon. Other must haves to use with this heater. Try it. You won't be disappointed!!

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 itUpdate. 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.

I am very glad about this purchase. Big Buddy Mr Hearter is great. Absolutely worth of the money.Also I like internal fan which flows the heat out and easy connection to a 20 lbs propane container.I use it in my ice fishing shelter in the forest. Minus 15 Celcium is not a problem even to sleep there all night.Thank you for fast delivery and high quality!

And so you're looking for a Mr Heater Big Buddy. If you shop around, you'll encounter conflicting reports to the effect that Mr Heater Big Buddy heaters sold in Canada come without the fan because of import fees??? You'll even read this stern word of caution on Mr Heater's own website.Fear not, Amazon sells the Big Buddy with fan and it works just fine. Just don't go pay 340$ for it. I insist on the fan given all the contraptions I had to assemble in the past to push my old Buddy heater heat forward. This time, it's built-in and no need for bungie cord or standing fans with powerpacks. The portable heater uses 1 lb cans that you can refill, that's a big plus. Construction is sturdy but I'm a tad disapointed at all the plastic in the back. I guess it is to be expected these days. Just don't expose it to extended sunshine and careful not to yank the propane chamber doors.About the fan: my advice would be to purchase multiple sets of Panasonic eneloop AA rechargeables (with compatible charger) and use battery converters to inflate them up to D-size. You'll be good for 4-5 hours of forward heat movement from one charge.Great product that I will keep around for years.

I t worked just great in our trailer .

Calienta super rápido super recomendable

Me gustó mucho el producto, es muy fácil de operar. Funciona mejor cuando enciendes el ventilador. No hay olores desagradables.

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.).
