Assuming you built your RMH out of an appropriate refractory material, then yes, you can burn any wood you want. It should be designed for much higher temperatures than the woodstoves that you might heard of being harmed by burning hedge. There's no wood that's off-limits. (I figure the wood you're talking about is hedgeapple, right? Bodark? Bois d'arc? Horse apple? Osage orange?)

I'm going to have to learn more about wood...this is new to me....I think its Osage orange. And yes I built my RMH using firebrick, refractory mortar, hardware cloth with perlite/clayslip, stove pipe for ductwork, bricks/rocks/cob for mass, no lime or cement used.
