5.0 out of 5 stars Mr. Heater Big Buddy Heater, 4,000 to 18,000 BTU Propane Heater
Reviewed in the United States on April 6, 2024
I purchased this product because despite running two very efficient and very expensive heat pumps, my home was always cold. Additionally, my electric bill was becoming more and more outrageous.
I was hopeful that the Mr. Heater Big Buddy Heater would at least be able to heat up my bedroom and also be able to heat up the master bathroom for showers and such. That said, I have been extraordinarily happy with the performance of the Big Buddy Heater. The heat output can be tailored to the exact needs of the moment, there are no unpleasant smells produced by the heater, and the fact that it puts out infrared heat makes it very pleasant to be near when the room is chilly. The heater is very easy to start with its piezo igniter and the heat produced is infinitely adjustable from low (4,000 BTU) to high (18,000 BTU). While the model I purchased did not come with the built-in heat distribution fan, I was able to add the factory fan with a purchase through Amazon (Mr. Heater Big Buddy Heater Back Cover Fan (E78404) (www.amazon.com/gp/product/B09S16JL8G)). I would recommend that everyone purchase the new Big Buddy Pro model that does come with the factory built-in fan. I use the Mr. Heater 6-Volt Power Adapter to power my heater's newly added fan (www.amazon.com/gp/product/B000HE6OAE). I also use the Mr. Heater 12' Hose with Regulator & Quick Disconnect (F271803) (www.amazon.com/12ft-Big-Buddy-Hose-Regulator/dp/B000UC7966) to supply low-pressure propane to my heater. I have found the Big Buddy Heater to be very efficient in its use of propane. It has saved me a great deal of money by not having to use my heat pumps to stay warm.
In summary, I have been overwhelmingly happy with my Mr. Heater Big Buddy Heater purchase. I have had no problems of any kind with the product. Further, I have been so happy with the performance of the heater that I have purchased a second one. Mr. Heater should be very proud of this product.

5.0 out of 5 stars A must have for Boondockers/dispersed camping
Reviewed in the United States on August 28, 2024
I just tried this Mr Heater in my travel trailer during a very unexpected cold weather episode in NW Washington state. My wife and I were dry camping when the weather not only turned cold, but overcast and rainy as well, unusual in August. Unable to maintain a charge in the RV batteries with our solar panels due to the heavy overcast, I didn't want to run the relatively inefficient furnace. So I brought in the Mr Heater, hooked it up to a 1 gallon propane tank with hose and filter and fired it up. It was extremely easy to set up and start, taking only seconds to start putting out heat. On medium setting, it quickly warmed up our 30' 3-slide travel trailer. Turned down to low it maintained a comfortable warmth all day, Very efficient, easy to operate, I now consider it essential to dispersed camping.
Definitely a strong recommendation.

Do Excellent product. Very powerful, easily heated our 10x10 canvas tent on some pretty cold nights. Takes 2 small size propane bottles which last 4 hours on high. Medium and low setting last longer. Read some compl9aints that it doesn’t have a fan as it used to but that’s easily remedied with any number of portable usb chargeable fans. Just a little circulation overhead makes a big difference. Great brand, portable obviously. The last night in Death Valley was very cold and was able be comfortable mostly on medium. Adapter is also available to add a larger size propane tank which of course means it would last much longer. Worth every penny. Good safety features, not too heavy.

4.0 out of 5 stars Works great but....
Reviewed in the United States on January 12, 2024
The 1 lb cylinders don't last very long so I definitely recommend hooking it up to a 20 lb tank. HOWEVER, don't use any hose but the hose made by Mr. Heater. Other hoses are not designed to operate at this pressure and will seep a greasy liquid which will soon foul all the connections inside. The manufacturer recommends using their hose but doesn't tell you that if you don't, the heater will quickly clog and will not work. I had to completely disassemble this puppy 4 times and blow out all the gas lines before I finally figured out it was the hose that was causing the problem. Save yourself a huge headache and spend the extra few dollars on their high quality connection hose. You'll be sorry if you don't. Otherwise, it works great and I highly recommend it.

5.0 out of 5 stars Lifesaver at cold events!
Reviewed in the United States on September 12, 2024
I bought this for our tent at the Ohio Renaissance Festival for October and I’m soooo glad I did. On high, it drives out moisture and raises the temps pretty quickly. On low, it staves off the worst of the chill. This is using it in an open front 15’ vending tent. If you’re using it in smaller places, it’s going to be even better.

Easy to use, and easy to load/reload propane canisters. On high this does go through a fair amount of fuel- just bring a few more than you think you need.

5.0 out of 5 stars Does not disappoint!
Reviewed in the United States on January 31, 2024
I've had my unit long enough to do some basic testing. And I'd like to preface this with the caveat that my goal is to have an emergency heater. Not something full time!. That means said I have full confidence in its ability to eat my two bedroom apartment in a winter emergency for extended period of time. That does come with an additional caveat in the form of requiring external fuel. But I'll be honest if you bought this thinking you were going to run it at full blast on the internal tanks then you might want to go into recreational Pharmaceuticals or rather than space heating. Because whatever you're on is some good stuff! It chokes down fuel extremely fast. At least compared to a catalytic heater such as those used in tents. But it puts out a comparably higher level of heat. And as for the construction I'm quite satisfied with that as well. I will mention of course that this is the fanless variant but I honestly don't think the fan would make that big of a difference in the long run. D cell batteries don't run a fan for that long! And if you have the power to plug the fan having model in then you can plug in something to generate the heat as well as the fan! So I give this one a five out of five. Very satisfied.
This rug is absolutely beautiful! Colors vibrant. Exactly what I hoped for. You do need skid mat under to hold in place. I am still waiting on it to flatten out all the way but it is beautiful!
