About Dragon Tech

I’ve been building and using Rocket Mass Heaters since 2013. Finding products for any RMH build can be challenging. Finding parts for a batchbox RMH has been even harder as most require metal fabrication.  At Dragon Tech we can supply you with the materials you need to build your own RMH, from batch box doors to Morgan Superwool Plus to secondary air flow channels and much more!

That's great your supplying this high quality product to the rocketeers at Permies Thomas.

I have been using it now for about a year and love it!

I just makes the process of insulating your Dragon so much faster and easier - whether its making a 5 or 6 minute riser, as an insulating wrap around your core, as an high heat expansion joint for dissimilar materials (cob and metal), lining part of the inside of your barrel to control where the heat gets directed to, or just wanting to ensure sensitive areas don't get dangerously hot (like wooden walls or floors).

Someone said its the duct tape of RMH's and I agree. So many uses.

Highly recommended to anyone interested in longevity at an affordable price.

I am glad there is an alternative to ceramic fiber, having something that is this safe is the way to go.    Thank you for posting.

This could be a real game changer.  One of the things holding me back from building a RMH is the expensive ceramic fiber board, fire bricks, cob, and the pain of working with all of it.  An 8" HVAC duct lined with 1" of this would be a super quick 6" riser.

I'd be interested to know the technical specs compared to Ceramic wool or fiber board?

Are there any pictures from builds people are willing to share?

Thanks and keep up the innovation,

Hi Bryan;
Yes, the non ceramic fiber blanket has been a game changer!
This Morgan super wool plus, is pleasant to work with.
Not sure what specs your looking for?
Performance wise it should be identical to the itchy, hazardous to breath, ceramic blanket.

Ceramic boards perform just as good but need to be contained by bricks.

If you can find high temp insulated firebricks, they would be another good performer.

What were you hoping to see?  I have lots of pictures...

Sooo 2 feet wide,...
that probably is the vertical length.
How long a piece does it take to line the inside of a 8" piece of HVAC?

2 pie R??

Hi Craig;
Circumference of an 8" pipe is apx 25" (8x 3.14= 25.12) So using 1" thick material  your looking at  23"  or so.
Here is a link to a previous thread when I built my first.     https://permies.com/t/95849/Working-Morgan-Superwool-ceramic-blanket
