Review: You can't use it if you don't have the gas cylinder - It looks good but it won't come with the gas cylinder Review: J'ai employé ce chauffe tente durant 4 jours. Il fonctionne très bien. Le bousculer légèrement l'étein aussitôt. Ma conjointe l'a particulière aimé durant les nuits de 14 degrés celsius. Par contre, il faisait trop chaud au moment de se coucher. J'apprécierais la présence d'un réglage de débit. À 3800 btu, la bouteille de 1lbs ne suffit pas pour toute la nuit alors c'est désagréable de changer la bouteille vers 4h du matin. Certaines personnes mentionnent des problèmes d'allumage. J'ai eu de la difficulté au début mais ensuite j'ai remarqué que presser plusieurs fois rapidement semblait laisser assez de temps à un peu de gaz pour sortir pour que l'étincelle puisse allumer quelques chose. En conclusion, nous sommes très contents de cet achat que nous jugeons très sécuritaire mais il faut avoir de la place pour l'éloigner des occupants et du mouvement. ## Features - 3800 BTU PER HR & COVERAGE: This propane radiant heater delivers 3,800 BTU with a 45° heating angle, ideal for small spaces like tents up to 95 sq. ft.

I'm afraid of fire and fumes, but the cub scouts insist in camping in sub freezing temps!** A: These are time tested and very safe, when I was a Cub Scout I wished I had one. Whether you buy this or not, if you do, my suggestion is to consider buying the GasOne 50180R or similar propane adapter and bring a larger tank so it doesn't run out by morning. Not suggest you bring a 20lb propane tank into your tent. But if your not backpacking, a slightly larger 5lb tank equates to waking up in a warm temp rather than the dreaded unzipping your sleeping bag and greeted by mornings cold. **Q: With an adapter hose can it be used with a large propane cylinder?** A: Not a problem. Make a 10"x10" box. Nail 2x6 together in the shape of a U. Then put 3/8" inch plywood on top and bottom (3/8" a must on top). Then make a 2 1/4" hole in the center of the top plywood. Next screw the main heater assembly into the filter with the top plywood in between (the two should come together snug leaving a very small separation which will allow the heater to rotate with no chance of a leak but still be secure). Then attach the hose and tank. This box allows for a large tank to be attached, the heater can rotate and the tipsy problem is gone.. Just remember to turn off the tank first to burn up the gas in the line before turning off the heater. **Q: Does anybody have trouble lighting this heater? Seems I need to hold the ignition button in for a minute and it really hurts my thumb.** A: Hey Spike, I agree with Thomas W. Mine wouldn't start on the first try either. You have to hold the ignition button down, wait a few seconds, then depress again. It's kind of a pain, but it works. A more annoying issue for me was wanting to use it in my golf cart, but with every tiny bump, the safety feature kicked in and off it went. So, it is safer for home use. For the cart, I bought the Coleman Catalytic Heater with the special holder that fits in the cup holders. It's more quiet too. Stay warm! **Q: Can you HANG this from something?** A: YES you can hang this heater. It's been done. https://www.youtube.com/watch?v=AZsVX6mh8O4 ## Customer Reviews ### ⭐⭐⭐⭐⭐ You can't use it if you don't have the gas cylinder *by I***M on 9 April 2020* It looks good but it won't come with the gas cylinder ### ⭐⭐⭐⭐⭐ Review *by J***R on 22 August 2020* J'ai employé ce chauffe tente durant 4 jours.

Whether I'm camping, working in the garage, or dealing with a power outage, this little heater provides reliable and efficient warmth. What I liked: Portable and Compact: It's incredibly lightweight and easy to carry around. The compact size makes it easy to store and transport. Powerful Heat Output: Despite its small size, this heater packs a punch. The 3800 BTU output is enough to warm up a small space quickly. Indoor Safe: The oxygen depletion sensor (ODS) and accidental tip-over safety shut-off provide peace of mind when using it indoors. Easy to Use: Simply connect a 1lb propane cylinder, turn the knob, and push the igniter button. It's that easy! Efficient Fuel Consumption: It runs for a decent amount of time on a single propane cylinder. Minor Considerations: Open Flame: As with any propane heater, it's important to use it in a well-ventilated area and keep it away from flammable materials. Not for Large Spaces: This heater is designed for small spaces. It's not ideal for heating large rooms. Overall: The Mr. Heater Little Buddy is a fantastic portable heater that's perfect for a variety of situations. It's compact, powerful, and easy to use. I highly recommend it for anyone looking for a reliable and portable heating solution. ## Frequently Bought Together - Mr. Heater F215100 MH4B Little Buddy 3800-BTU, Indoor Safe Propane Heater With ODS & Tip-Over Protection, Heating Area Up to 95 Sq.
