    • Mr Heater “Big Buddy” heater
Color: Grey
This heater is very portable and you can use the small propane cylinders or connect to a larger one, that is what I did so I ordered a connector hose to my 20 lb propane tank and the heater. I used it and tank inside with a carbon dioxide detector nearby. I wouldn’t have been brave enough to have tried this on my own BUT I was visiting a home that was and was amazed at the heat it gave out. It is energy efficient, has safety features built in ... show more

    • Works better than imagined!!
Color: Grey
Easy to set up and connecting the hose to a propane tank was okay (had some issues at getting the hose to connect and twist on the first time). Once connected, the easy of it lighting was so much better than I expected. The heater puts out a constant amount of temp to heat. I keep mine on low and it keeps my RV easily at 70°. I do keep a window cracked for ventilation, but it does an outstanding job. Highly recommend this. It will work great in garages, emergency heating for a house or as a constant source (provided that there is a window cracked for ventilation), as a travel heater in a RV, and so much more. Has a tip over emergency shut-off switch to prevent fires from starting. There are 3 heat settings as well, low, medium and high (which uses both panels at once). This is a great product for the price and a good investment to have if the power happens to fail..at least you and your family/pets will stay very warm. ... show more

    • Great heater - with one issue
Color: Grey

Pros - With a CO monitor and plenty of ventilation, it kept my Gazelle T4 8'x8' 3 season tent warm (comparatively) on low heat when the temps fell to 2 degrees F. Ran it at night for 6 days straight for about 10 hours each before the 20lb tank died about 2 hours early on the last night. Made camping/sleeping in frigid temps very bearable. D cell batteries for the fan worked for at least 2 days/20 hours. 20lb tank hose worked perfectly and was easy to connect. Unit is very light. Power adapter and/or spare D cell batteries (2 per use) can be stored in one of the two 1lb tank spaces. Cons - the fan made a screeching noise when it turned it on for the third night. Was afraid it was the fan bearings but changed the batteries just in case. Noise went away. Fourth night when I tried turning it on it wouldn't stop screeching. Tried the AC adapter for S&G, no luck. Fan bearings were shot. Ran the heater the last three nights without the fan on and had noticeably more cold areas in the tent - especially down low. Currently working with support to get a new fan assembly. Hopefully they come thought. Summary - Great heater for small spaces. Fan might be an issue for extended use and is pretty anemic even when it is working. Use the large tank hose with the quick disconnect for long term use or high heat output. Overall a great thing to have when you need more heat and a circulation fan as compared to the Hunter or Portable versions. 12/14/22 Update - contacted support and they responded quickly and more than willing to help. I provided my serial number and they sent me a new back panel with integral fan. 4 screws and the panels were swapped out. Fan isn't the best quality but hopefully the replacement lasts a bit longer. ... show more

    • Best camping heater out there

    • Works great!
Color: Grey
Very pleased with this purchase. I was surprised how easy it was to hook up to a 20gal tank with an attached hose and filter. The fan is nice but is a bit weak on power. All in all it's very quiet and no lingering smells.

    • I've noticed complaints about ignition
Color: Grey
So far this unit has operated flawlessly for me, but I'm wondering if some of the people having trouble with ignition with a hose to a 20 pound don't realize they have to purge the hose to get it to light, as follows Steps 6 though 8. Step 8 explains that you may need to repeat these steps to light the pilot.: LIGHTING / OPERATING INSTRUCTIONS FOR USE WITH HOSE CONNECTED TO A REMOTE CYLINDER, MAXIMUM SIZE 20 LBS 6. Depress and turn Control Knob counterclockwise to “PILOT” position and hold down for 1 - 5 seconds. See Figure 4. This may take longer to purge air from the supply hose depending on the length of the hose being used. 7. Depress and turn Control Knob counterclockwise to “PILOT” position. Ignitor will spark to light the pilot burner. Hold control knob down in “Pilot” position for 30-60 seconds. 8. After lighting pilot, release knob. Knob should return to fully extended position. See Figure 5. (If needed, repeat these steps until pilot lights). ... show more
