I was concerned when I purchased this unit. There are a number of highly negative reviews on it. However, on further research, I have discovered that the circumstances leading to those reviews could have been avoided.

When one uses this heater with a 20 lb propane bottle & accessory hose, it is imperative that you always shut the tank off first & let the heater run until it burns off all the fuel in the lines.

*** IT IS IMPERATIVE TO FOLLOW THIS PROCEDURE ***

If one simply turns the heater knob to the off position, it will trap trap 100 PSI of propane in the accessory hose. When high pressure propane sits in the rubber hose, it will chemically react with the rubber and leetch a light oil. The oil will build up and quickly work its way into the heater, clogging both the regulator & control valve.

Another very important recommendation is to purchase the gas line filter. This will catch the oily residue and protect the combustion components of the heater should one forget to follow the precautions above.

Keeping these precautions in mind, one will be able to enjoy a very well-build and flexible-use portable heater.

I don't know why people are having so much trouble with this heater. This is a great product which has made living in my off-the-grid cabin bearable even in winter.

PERFORMANCE IN COLD WEATHER
For the past 5 years, I've used the Big Buddy heaters to heat two small cabins, 200 sq feet each, with vaulted ceilings. Without the Big Buddy, my primary cabin averages 37 F in the winter, and my studio averages 35 F. With the Big Buddy, I can keep either cabin at a toasty 65 to 70 F. In the past, I used the smaller Mr. Buddy for years to heat a tent in winter for 2 weeks at a time while working in the mountains.

How long to heat a space?
Cabin: From full cold (37 to 45 F indoors), it feels like it takes forever to heat 200 sq feet on low. On high, my cabin is toasty warm in about 10 to 12 minutes. The heater then keeps the space too warm, so I have to turn it down to low, or start cycling it on and off every hour.
Tent: It never heats the tent; too much loss through the tent walls. It just provides a radiant heat source for the side of your body that faces it. I could never decide if that made things better (to have some heat), or worse -- one side warm and the other freezing my hiney off.

BOTTLE VS TANK + FUEL FILTER
I have used both the Mr. Buddy and the Big Buddy with 1-lb bottles and 20-lb tanks, with and without fuel filters. Over the past 10 years, I have had only one failure -- one heater clogged with a 20 lb tank (no fuel filter). All my other heaters have performed flawlessly, and I've had 2 Mr Buddies and now have 5 Big Buddies (I gave away the Mr Buddies and went solely to the Big Buddies). I started using fuel filters only in the last 8 months.

I don't agree with some of the reviews. I don't see that it's a fire hazard at all. My Big Buddy was delivered last week. Here's what I found:

My elevation in Virginia, About 800 feet

Ambient temperature, 72.8 (in my house). Outside temp 29.0

1. Running on high on ONE Disposable Cylinder caused unit shutdown after 50 minutes. (Pilot started to flicker, cut out and then gas shut down). Single bottle was covered with ice (I assume that's bad...)

2. Running on TWO Disposable Cylinders got me the balance of three hours smoothly and well.

3. No fumes observed at all. Some moisture, but cracking the window an inch kept it under control.

4. A lot of heat. Too much for my wood floor. I had to put it on my brick mantle. This might scorch tile.

5. It kept my upstairs (1000 square feet) at 72.5. Only a loss of 0.3 degrees over three hours. Better than expected.

Suggestion: If you are trying to run on high with disposables, use two of them. This is not in the manual.

I don't know how it works with tanks, or whether you need to feed one or both inputs.

My unit did not come with the AC adapter. The batteries work.

If you bump it gently, it shuts off.

Conclusion:

For 139 bucks, it fits the bill well enough. It appears to be very well made, but the safety features make it tempermental. For my use as an emergency heat source, it's adequate.

I've been fumbling, stumbling, and bumbling along trying to obtain the "right" combination of MR HEATER items to allow me to use their BIG BUDDY product. I strongly suggest that you decide on which heater you want, then go to [...] and pull up the web page for that heater. Find the FAQ section for that heater. Read through the "problems" very closely. You will find there are valid reasons for those problems to occur. MR HEATER explains and provides solutions to those problems in the FAQ. One thing, in my humble opinion, is missing in the descriptions ~ If you are using larger than 20-lb tanks, you may need a "regulator" to control the pressure from the tank to your heater or other small appliance. Check with MR HEATER Tech Support before you run into problems. Be patient and be very clear about your setup. Everyone I have contacted has been very helpful and responsive to my questions. MR HEATER also provides information on the SAFETY RECALL situation with a possible solution on what to do with replacing a faulty heater.
