5.0 out of 5 stars Match your Mr Heater with the right Accessories, February 12, 2006

By	The Putze "Marty" (California) - See all my reviews

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 www.mrheater.com 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.

3.0 out of 5 stars Good heater, but kind of finicky., December 24, 2004

By	Virginia Coldness "Bryce" - See all my reviews

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.

5.0 out of 5 stars Great heater when simple precautions followed., January 21, 2009

By	Christopher S. Mooney "Moondawg" (Schaumburg, IL United States) - See all my reviews (REAL NAME)

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.
