Welcome to 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 now supply you with secondary air floor channels in Two designs!

Introducing the new Quick Change secondary air tube with an easily and quickly replaceable “cobra” style air stub or a 6″ Walker style stub

Changing out your degrading stub in just a few moments is now a reality!
