The Mr. Heater Big Buddy Heater adds warmth to your garage, barn, ice shack and more. It's quiet, odor-free and heats up to 300 sq. ft. The Buddy connects directly to 1 lb. cylinders of propane via a convenient swivel regulator. The fold-down handle gives you the maximum heat output, while keeping a minimal footprint. Lighting the unit is quick and easy by pushing the down the start knob while on pilot. No more numb hands or chattering teeth!

Safe heat…for years to come.

Small and compact, the Mr. Heater Big Buddy is packed with features to keep you safe and secure, while keeping yourself warm. The Oxygen Depletion Sensor (ODS) automatically shuts down the Heater when there's not enough oxygen surrounding it. This will prevent the unit from continuously using the oxygen in your shack, and leaves it for you. The accidental tip-over safety shut-off turns the unit off if it's tipped over by more than approximately 45º. This prevents it from igniting your shack, grass, or papers on fire. Always remember to leave plenty of clearance around your heater for your safety and for the safety of those with you.

Mr Heater Big Buddy Portable Propane Heater, 18,000 BTU is rated 4.8 out of 5 by 133.

Rated 5 out of 5 by Mobile Sniper from Perfect heater for the garage, camping, and the cabin I love this heater. Plain and simple. This is THE heater to get if you have a two car garage, are looking to keep the hunting tent warm, or quickly warm the cabin while getting a fire going. This heater heats my garage no problems. This replaced a previous one that I had purchased from the SG, and had given to a battle buddy (and fellow hunter) who was being stationed up in Alaska. With the built in fan you can easily and quickly heat a two car garage. My garage is finished, so it holds heat decently well...but when the temp gets down to 54 degrees I fire this baby up and run it on high...after about 30 minutes I turn the fan on to force the hot air through the garage. After an hour the temperature has risen to 64 degrees (yes a full 10 degree increases). I then kick it to the medium setting (before turning to the low setting for 30 minutes to allow it to cool without a rapid decrease) and allow it to run at medium for an hour. By the time i'm done my garage is a comfy 72 and stays that way for several days (even if it's single digits outside). I have mine hooked to a 40lb bulk tank...but fair warning if you're gonna do a bulk tank you NEED the fuel filter and wanna check the connections before running indoors (unless you want to risk explosion). A side note for you...mine arrived with NO electronics (i.e. the fan, switch, and battery compartment). Instead of sending it back to SG, or griping and complaining, I contacted Mr. Heater and they IMMEDIATELY got a replacement back plate out that contained the fan etc. and at NO cost to me. They even overnighted the part!! So the customer service for Mr. Heater is as good as at the SG. You can't go wrong with this staple item, that is part of our bug out gear. I'll update this review with a photo next time I run the heater in the garage.

Rated 5 out of 5 by Ed C from Awesome I have had mine for over 10 years now. I used it in my pop up camper for hunting trips in the Adirondacks. The past 5 years it’s been in my pop up hunting blind. Heats perfectly. I use a 20lbs tank and hose and filter. I clean it at the end of every season no problems. Great addition to keep me out hunting in very cold conditions. Highly recommend the big buddy heater

Rated 1 out of 5 by Rick from Does not come with a fan as the video and other reviews state. I would not buy this item again does not have the built in fan as it states in the video and many people have posted that it does. I opened mine today and went to put batteries in and nothing there. Called sportsmansguide and they stated this model does not come with fan. So don’t be like me and watch the video real all the specs. Also the unit is cheaper locally with the fan but the 4 pay got me. I repeat does not have the fan.

Rated 1 out of 5 by Kathy from Not happy The people at Mr. Heater need to check their products before they go out to us the consumer. Went to hook it up & get it ready for hunting & opened the battery compartment up to install the batteries & there wasn't anything there to hold the batteries in. I had to return it to SG and didn't have any heat in my blind for my muzzleloader hunt. Was very disappointed they let it go out this way!

Rated 5 out of 5 by Spyder 7 from Great price and great quality I love the size of the ceramic heaters surface. Gives off lots of heat and lasts a long time with the double tank supply. Great for tailgates and working in my garage during cold weather!!! I recommend this to anyone for personal use like this!!!

Rated 5 out of 5 by The Commander from Works as Described Read a lot of reviews especially with adapters and so forth. Starts right up.......Heats up everything for 7- 8 hours. And you will have no concerns about keeping it indoors. Use Mr. Heater adapters and hoses for the larger tanks and all will be good.....Really great product the way things used to be built in this country....and not China. Great Price from another American Company - Sportsman Guide!
