Big Buddy

Recommended Posts

I was out today and really needed the heat from my big buddy. It was tough to keep the heater going and when its -14....i really needed it! It seemed like I was constantly messing with the heater which cost em fish. It would keep shutting off and then I would have to hold the ignite forever just to get the pilot flame to stay burning. It would then light real hard on the low setting so I would turn it to medium and it would light right up for 5 to 25 min before going out again. I did a lot of old post reading and couldn't come up with a solution. Is it the small tanks freezing, a problem with the o2 sensor, tip sensor, or user error?

I am already thinking of switching to a 5# or an 11# tank when I get the funds to upgrade.

I think your tank may have been empty or frozen up. I had the same issue and it was the 1lb tanks. Try another if you have one with you when it happens.

high heat in a small shack equals low oxygen. Keep a window(zipper) cracked a little. My dad and I ran into this with a small radiant LP heater in a canvas portable. Scarry stuff. Tip: If you light a lighter and the flame dances above the lighter a bit...there is a low oxygen level. That's how we found this out.

I have a hard time believing its low oxygen... 15mph wind in a quick flip II = decent amount of air moving around. I did have a vent open and it still happened. Could it still be low oxygen? I also tried brand new tanks I had with me with the same results.

If you have the 1# tanks I think they have issues when it's really cold because they freeze up.

I tried running mine to heat the garage this weekend with the same results as you. After the second time it went out I looked at the 1lb tanks and they were froze. I let them thaw for a couple minutes gave them a good shake, fired right up and was good to go.

I bought a big buddy, used it when it was 10 below and was not impressed, sold it the next week and went back to the sunflower, but i think i would check you 1 lb tanks.

Unless your 1 pound tanks were warm when you started they would have caused your problems cause they could not generate enough pressure to run the buddy when they start out frozen. Next time keep them in your truck in a warm cooler and see if it makes any difference.

not a problem with mine so far,(knock on wood) have had it out a dozen or so times hooked to the big tank and love it, bring a few 1#ers with just in case she runs low. i picked up a refurbished one at cabelas for pretty cheap so hopefully everything got looked over twice! Do you use the fan on them at all? I guess i really havent messed with that, does it work ok?

I had this same problem last season with the 1lb tanks. They would freeze up after I had it on high for awhile. If I only need medium heat, they would do alright.

This season, especially with the colder temps I have been using my 20lb tank and can have it on high for hours on end with no problems. A lot less frustration!

I had this exact same problem with my regular buddy heater this past deer season and I run off a 20# tank. The problem still existed even when i was trying to run the heater in my heated garage, which is set at 68 deg. I took the heater apart and cleaned it and still don't work. From everything that I have read on here and on Mr. Heater's trouble shooting it is either the control or the regulator. I just have not got around to buying the parts to fix it yet. If I get it fixed I will definitely being running the filter on the hose. Have you ever ran your heater on a big tank with a hose and no filter? Could be pluged up.

I have a Big Buddy and had the same problems with the 1 pounders when it was really cold out. I had my 20 with so I switched it out and worked fine after that. Like jimalm said, they can't get enough pressure when its that cold out.

I ran mine to heat my garage last weekend but with a 1/4 full 20 lbs tank, no issues at all. Sounds like the issues everyone is having are related to the 1 lbs tanks.

Yup those 1lb tanks don't work well when it's really cold. I now carry a 20lb and it sucks draggin it, but it sure is nice not having issues of it going out when it's -20 wind chill.

You are experiencing a frozen tank problem. A half full 20 pounder is better than a full one because your surface area in the tank is more open to draw the LP gas. The smaller tanks, like the 1 pounders will be more apt to freeze up as well because there is a smaller area to draw the gas from. this was explained to me by a gas supplier. Not sure if I explained it well.

I have never hooked it up to a big tank. If I remember right, I had small problems with it last year too when it would just shut of randomly...and that was even on the decent weather days. I am going to start looking for a 5-11 lb tank. until then, I need to somehow get by on those 1 lbers. If the temps would ever get back up again....

Maybe try leaving it in a warm vehicle if possible until you get the house set up and ready to have some heat. If you are walking out maybe take them from a warm vehicle and put them in a cooler to try to keep them warm until you get the house set up.

    • It might be better to buy a small second unit and link them.    My guess is what you want is not something enough people want to justify implementing.   Personally I have a hard enough time watching a bobber.
    • Welcome to the Forum.  What brand gun is it? Would help to pick choke tubes out.  Size 6 shot should do the trick, but I'm sure more folks will chime in here. 
    • I upgraded my electronics this year to a Humminbird Helix 10. I love it so far with the exception of not being able to split the screen into 4 separate screens. The max that you can do is 3. I would really like to be able to have the map, sonar, down imaging, and side imaging on the screen at the same time while trolling. I emailed tech support and they said it's not something that is an option at this time. Right now when I'm fishing I switch back and forth between map, sonar, and DI and sonar, DI, and SI. Is there anyone else that thinks this should be an option? I don't know see why you can't customize the screen to show whichever features you prefer instead of only using the preloaded options that Humminbird decided on. I have thought about emailing the company weekly asking if they have that ability yet but wanted to see if anyone else thinks it should be an option. 
    • I just purchased a used 20 gauge for my 14 year old daughter. I hunt mostly state land for pheasants. It is a 2 3/4 auto with interchangeable chokes. What size steel shot and choke tube would you recomend for her?
    • I just got back from a work trip to MI. I could not believe the difference in ground cover. We traveled all the way from Dearborn back to Bemidji heading through the U.P.  Most of MI had very little ground cover but WI was flush, green everywhere! I only got to check a few spots at rest areas but I never saw a thing. The ground was dry at most spots on the way home. I'm gonna go hit my spot tomorrow, hopefully it hasn't been picked yet!
    • love those when ya see them!!!
    • Took the kayak crappie fishing opening weekend and when calm always bring with the DSLR with. These turtles are glad the weather has finally consistently warmed up. I always find it funny seeing turtles stacked on top of each other and found a few along with multiple species which was nice.     
    • I was going to hunt wi this weekend but fishing musky with my fly rod is what I will do instead.  Good luck!!!!!!!
    • Anyone still at it?   not sure that i will get Isaac out anymore, will still ask these last few days.   Good luck everyone.
