Q: Does this heater require a filter when connected to a 20lb tank, similar to the filters used on other big buddy heaters?
4 years ago1 Answer
- A: Thank you for your inquiry. The Buddy Flex Heater (F600100) does require a fuel filter when connected to a 20 lb. propane cylinder, unless you use the 10' Buddy Series Hose (F273704). This specific hose is made out of a special material so it does not leak oils and residue into the fuel line like other propane hoses do. Some other hoses that work with the Buddy that require a fuel filter include F273701, F273702, F273703-60, and F273703-144. Have a great day!4 years agoHelpful?
Q: Is this heater safe for heating my indoor workshop?
4 years ago2 Answers
- A: The Buddy Heaters can be used safely indoors using 1 lb. propane cylinders, or with a hose and larger cylinder as long as the cylinder is kept outdoors. The Buddy Heaters are equipped with an ODS sensor that shuts off the fuel if the oxygen level in the room drops from 21% (normal air) to 18.5% oxygen by volume or below.

Love it!
5 years ago
I bought this new Flex heater and the Flex cooker and I love it! They just arrived today and I put it all together and tested it out with the 1 Lb tank and had ordered the F273704 hose and tested it with the 20 Lb tank. They both work perfectly. I heated a couple of cups of water in less than 2 minutes on the cooker. I am thrilled to have this set as it was taking me countless hours researching which heater and which stove to buy. It's beautiful esthetically also. The battery compartments have itty-bitty screws and the locking piece for the heater compartment broke when I was trying to figure out how to open it; that is the only design flaw that I found as everything else is as wonderful, and even better now, as you would expect from any Mr. Heater, Buddy appliance or system. There is a little storage like cabinet on it and that would be a great place to put a tiny, magnetic screwdriver, I guess. I attached the heater to the cooker and it's not too heavy but it is not light either! I would buy nothing else, given a choice of the heaters and stove's out there, but this set for my little camping, hunting rig and I would highly recommend it to anyone!

I have had this awhile and it has never worked. The pilot light will light easy and you think your winning. When you try to turn the knob to low the pilot goes out. I called Mr..Heater and they said it was likely the hose. No problems like this with the other dozen or so Buddy Heaters I have owned. If it does light after 30 minutes or so of jacking with it the fumes are unbearable. I bought because I was using in a deer stand and didn't want the loud clicking sound. Do yourself a favor and pass on this one.

Don't buy this
6 months ago
Do yourself a favor and don't buy this. I've had one for 2-3 years and have only used it a couple times in that timeframe and now it will no longer light despite trying everything to fix it. Mr. Heater's customer service is no help either and they don't stand behind their products.
No, I do not recommend this product.

So far have only used it once but it's a really nice heater. I do like that it's got a windshield over the pilot light to keep it from going out. This thing also hooks up to a mini stove attachment which is really cool. Pretty nice heater

I will keep it for emergencies but I wouldn’t buy it again. From a 1 lb cyclinder run time is 1.5 hr on high, 3.5 on low. With a 20 lb tank runtime is only 36-72 hours. Hugely expensive to run.
Plus, if you want to run it from an external tank you have to buy their adapter hose and additional fuel filter. You are better off just buying the regular screw on one for $60 on TEMU.
Yes, you can refill your own one pound canisters but do you want to do that every three hours? Not me.
Be aware that in Nov 2024 Newsome signed into legislation the banning of all sale of one pound canisters.
No, I do not recommend this product.
