The 2021 Rocket Mass Heater Jamboree
was a blast. I got to meet Paul Wheaton, see Chris "Uncle Mud" again, and meet face to face with many of the other builders and some people
that were interested in the Liberator Rocket Heaters
we produce. I also got to see and test the Gamera Rocket Heater
, a well built stove, hands on and in person. It was an excellent time, even if I was only able to stay for a couple days. I look forward to attending the next Rocket Mass Heater
Jamboree as well. I got to fire up Pauls Rocket Mass Heater
in the Fisher-Price House, and it was a very inspirational moment. I always knew that 8" core rocket mass heaters were good, but I didn't grasp how much better they were until I experienced it in person. There is a bright future to be had in this regard.
Whilst I'm thinking about it, I wanted to give out some updates as to whats been happening on our end. Some of you guys may already be familiar with the Gen 2 Liberator Rocket Heater from the video
's that Chris "UIncle Mud" has published, linked below. This heater has been in development for a long time (some, including myself, would say too long) but the wait has been worth it. Linked here is Muds Video
The first bit of news is that we're introducing a second generation Liberator Rocket Heater. And, just like the previous Gen 1 Liberator Rocket Heater
, we're fully building code compliant to UL-1482, ULC-S627, and additionally, ASTM-E-1509 for pellets. However, we received a lot of helpful feedback on the drawbacks of that design, particularly the lack of insulation on the combustion chamber and riser. So for this heater, we decided to include ceramic refractory fiberboard insulation into the design, a removable cooktop plate to facilitate easier cleaning and maintenance, we nixed those old ugly cooling
fins that reduced efficiency, and now offer custom paint colors. A replacement fireglass door for the Gen 2 is something we would like to introduce next year. And I can testify, the insulation went a long way towards improving the burn! the EPA certified testing lab concluded their emissions test results on the Liberator Gen 2 Rocket Heater this week, and we have the third cleanest burning room heater in the world. So we get the bronze medal. At 0.38 grams per hour of solid particulate, we're barely behind a catalytic stove and an electric pellet stove. Not bad for a gravity fed non-catalytic rocket heater with a 4" core! This is actually much better than I had originally hoped for. The test results are provided below. These test results also vindicate every rocket mass heater
builder and espouser, that has battled for years to get the recognition and respect they and this technology deserves. Henceforth, anytime some particularly negative person wants to say "If rocket stoves we're so great. . . ." We all can just point to these test results, and show them the proof.
The second bit of news is that we've been renovating a new factory to keep up with the high demand. This has been a long process, taking far longer than we had originally hoped for. But the progress is coming along, and we're almost finished. Attached below is a before and after picture. We've hired a few new helpers to speed up production, along with acquiring some new machines.
This has been quite the journey thus far.
We will be accepting pre-orders again soon. Demand has been very high, so I don't think
they will be available again for a while after we fill these backorder slots. Also, we made a new website, rocketmassheater.com
. Please let us know what you think, and dont hold back on the criticism!
I've also attached a PDF of Liberator Gen 2 Rocket Heater's owners manual, which covers installation, and may be of use to someone thinking about building a rocket heater, or might be of interest for their considerations.
If you have any questions, feel free to ask. If you have any thoughts, criticisms, requests, recommendations, ideas for an improved version, or etc. that comes to your mind I'd be elated to hear them.
