    • Mr. Heater Big Buddy Heater, 4,000 to 18,000 BTU Propane Heater
Style: Space Heater
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. ... show more

    • Great heater for indoors and out
Style: Space Heater
We purchased 2 of these heaters a Big Buddy heater and the smaller portable heater. Both to run on 20lb tanks for use in our kitty cottages for our rescue cats. The larger heater gets very warm and we have only needed to use it on medium and high twice for 2 minus degree nights other wise a 2nd smaller portable heater would more than sufice. Heaters are well made and rugged feeling. Tip over switch cuts the flame quickly. Both heaters will run on smaller 1lb tanks. I'd say on low both heaters run for four or five 8 hour nights on one 20lb tank. We purchased the 10 and 12 foot hoses to use with the heaters so we can keep the tanks outside of the cottages. My only gripe with the large Big Buddy heater is that the hose can only be mounted to one side of the heater and the space to get your hand in there to hook it up is small. We love the fact that these were designed to be used indoors as compared to many other propane heaters. I saw another review by a outdoorsman who routinely travels with his heater and sort of puts it thru some abuse in the back of his truck and the heater after 2 years still works due to rugged design. Our heaters wont see that but I feel its probably true. Highly recommend !!! ... show more

    • Warm yourself by this fire!
Style: Space Heater
This is an amazing heater! It arrived packaged nicely with no issues. It was easy to unbox and easy to follow the instructions. Installed the tanks and BOOM, I finally had warmth in my fully tiled ensuite! (You know how cold tiles get when it's cold outside and you don't have floor heaters built in!) As a matter of fact, I have to set this to the lower setting because it does such a great job of warming things up. I use it for the ensuite, the deck, and the garage and it works fabulously (much better than the other heaters!) Just put it in your basket, you won't be dissapointed. ... show more

    • Powerful, Portable, and Perfect for Indoor & Outdoor Heat
Style: Space Heater

Review Image by Steven Steven
The Mr. Heater 4,000-18,000 BTU Portable LP Gas Heater is a must-have for camping, garages, emergencies, or chilly outdoor gatherings. I’ve used this heater in a workshop and a tent, and it provides steady, reliable heat with three adjustable settings to suit different needs. The dual tank connection is a huge plus—it runs longer without frequent refueling, which is great for extended use. The built-in safety features, including tip-over and low-oxygen shutoff, add peace of mind when using it indoors. The rugged handle makes it easy to move around, and the black/red design looks great. Setup is quick and simple—just connect the propane tank, ignite, and adjust the heat level. It works great with 1 lb. propane cylinders or larger tanks using an adapter hose. One small thing to note: It’s best used in well-ventilated areas, even though it has safety features. Also, if using with a bulk propane tank, a fuel filter is recommended to prevent residue buildup. And here’s a quick joke: Why did the heater get invited to every winter party? Because it always brought the warmth! Overall, the Mr. Heater 4,000-18,000 BTU Portable Gas Heater is a powerful, efficient, and versatile heating solution. It’s easy to use, reliable in cold weather, and great for both indoor and outdoor use. A fantastic investment for staying warm anywhere! ... show more
