Question: Is there enough of a chimney effect to be able to start up charcol without using lighter fluid?
Document: propane tanks for camping. I was surprised how long one small tank lasted. I also have plans to use this, instead of my turkey fryer, for heating my hot water bath canner. Again, I do this to prevent heating up my kitchen as much as possible. The Volcano certainly seems like it will put out enough BTU's (using a 20 lb.
It works great as an oven with the volcano lid. It is just big enough to cook two large steaks at a time.
I only gave it 4 stars because the legs are a little small for the size of the unit. I am careful to keep from bending it, so shouldn't be a problem, have not used the gas burner attachment yet but looks and feels sturdy enough. I used a wood-fire to do some grilling, surprisingly good heat with very little fuel.The fold-out design is great too
Sturdy, practical. Cooking on this grill with Dutch oven is fantastic. Used it this past weekend to make fantastic ribs and  fish fry. Eliminated using stove in the house all weekend long!
Great Product easy to use, cleans up quick, sturdy. I would highly recommend this item. Another not related note is that using amazon to order stuff is quick easy and thankyou.
I bought this because it made more sense than the normal charcoal grills. I was able to set it up and cook on it within minutes. Clean up is a lil tricky at first but over all it turns what ever you use (wood, charcoal, etc...) into carbon dust which I turned around and used in the garden. I recommend it especially for those who can never get to the store to buy the briquettes or fill their tank.
The Volcano is a well made product that will last for years. I wanted the Volcano for its ability to use propane, wood and charcoal. The Volcano is even more versatile than that. In an emergency, it will also cook a meal using tealights. With the lid on, it builds up substantial heat using tealights as fuel. I love this stove's versatility.
Guess what? It worked! With the oxygen control lever, you can control the heating intensity vs length of burn. I was able to cook a full 12" Dutch oven full of apple crisp with only 15 briquettes! Thanks to the retracting legs, you can set the stove on almost any surface while cooking. In my case, I set it up on one of my small folding tables you can buy at Wal-Mart or Target.
We've had a fairly hot summer (for us) in Wisconsin. Who wants to heat up the kitchen and then pay to cool the house back down? The stove will probably pay for itself by the end of the summer in saved utility costs. I ended up adding the cover, which does make baking in a Dutch oven more consistent. I'm intrigued by using the cover to make a mini-smoker; but, haven't tried it.
On top of this fiber glass I put the charcoal. I experimented and found that in 10 degree weather I could cook a pie with the same crust browning results using only 11 charcoals, 5 on the bottom and 6 on top. (I used a 10" aluminum dutch oven to do all this).I love my new and improved volcano, it is super efficient and expect it to be a great asset in the event of a power outage.
