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.

Powerful, Portable, and Perfect for Indoor & Outdoor Heat
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!
