Question: Do you need to weld to use this kit? Thank you.
Document: Little about this kit is suitable for long term use. The barrel face will warp under the door, creating numerous air leaks. The air holes are too small to keep the fire going and create backpuffing. The latch is completely hopeless. The legs are too short and need a front to back brace. But the pipe flange is good. I'll mention what I did:  I cross braced the legs and raised the stove on two cement blocks. The stove legs are bolted to the blocks. I used 2 kits.
This barrel heater kit is the best thing I've ever purchased. I should have gotten one years ago. Absolutely love it. I would recommend it to everyone that has the space to use it in.
I purchased this kit to create a barrel stove for outdoor use. I have converted mine into a water heater/pool heater and it has been working very well. The kit comes with the cast iron door, legs, and rear vent collar. It is well built and the kit contained all of the mounting hardware I needed.
this is one of the best items i buy it on line it does exatly what they say ill do amazing results. thank you good invention.
went together really nice and it really heat's the area great. Putting it together we did pretty good until we put the legs on wrong way but we were about to correct it quickly. Thank-you
I'll be able to roast a pig using firewood. We have lots of trees to use as fuel for our roasts!
Bought it for shop rec room. Great use for 55 gal drums that pile up. Works great easy to assemble. Keeps rompa room toasty!
Was looking for a way to heat a small steel building...And here it is! Assembly was easy. Legs were a little short, but I was aware of this. Just used some cinderblocks under the legs to bring it up from the floor. Brought temp of bld{20x30} up to a workable level of comfort. Beats buying a wood stove for hundreds of dollars. Parts can be swapped from one barrel to the next when barrel starts to give way from use.
This is an excellent stove - I have used the double barrel type for 3 years - but you need to be aware of one thing. The stove [...] door bracket (part number #6 - see it on the "replacement parts" downloadable .pdf hyperlink) is made of exceptionally thin steel that will bend when you close and secure the cast iron door. Several days ago in the night the fire alarm went off.
very nice, heavy duty kit,,,,,,,great shipping too
Answer: No welding required.  It comes with small bolts/nuts to install.  However, you DO have to cut several openings in the barrel.  I'd encourage you to get the removable lib barrel instead of a closed barrel, it's very tough to reach deep in the barrel to install the leg and flu bolts.
