So we've been burning this heater for about four years now but finally got around to hooking it up to a thermal mass and giving it a good firing and a review. Sky Huddleston has done a good job balancing the needs of mass production with the fine tuning that lets rocket heaters burn so clean. You COULD build your own rocket heater out of mud and scrap metal and it MIGHT work as well but it would probably not be code approved as a woodstove and UL Listed in the United States like this one or give you the choice to burn pellets or wood scraps. This is a really good heater for the money. Check them out at rocketheater.com and they will give you $100 off if you tell them Uncle Mud sent you.

There's a special moment when we get to fire up a heater and see how it runs.

That’s a nicely made stove. Have you tried it with outside air supply hooked up? I wonder how much overall efficiency is gained with outside air hooked up? Does outside air work ok when burning pellets? Does the pellet hopper come with it?
Thanks

I’m looking at getting one of these for my cabin in snow country. I’m curious what your overall experience has been and specifically, how often you’ve had to replace the grate at the bottom of the fuel chamber. It looks like that could be an annual expense. Thanks.

I got a liberator 2 this fall:  I burn wood or pellets, depending on my split wood supply.

The grate for the pellets is not showing any sign of corrosion.

There’s a good discussion about the stainless steel grate here, and a lot more information from Sky Huddleston, designer and manufacturer of the liberator 😊.

I recommend the Liberator stove, and see a nicely done thermal mass in some of the photos in this thread.  https://permies.com/t/208528/Free-Shipping-Liberator-Rocket-Heater

Unfortunately I didn’t get a mass built for mine, because I got it so late in the fall.

I may be selling my stove once the heating season is over, because I’ll be selling my house, and don’t feel comfortable leaving it in the house for a person totally unfamiliar with rocket stove mass heaters.  Pass the word along, I will be selling at a reduced price, and someone would have to drive to north eastern California to pick it up.

Pass the word, and drop me a pm!

 
Ever since I found this suit I've felt strange new needs. And a tiny ad:
