Outdoor Rocket Mass Heater

Hello
Echoing a previous post about the pitfalls of having a rocket mass heater in the house,  I am looking at the outdoor wood furnace industry uses with an outdoor unit that transfers the heat indoors via hot water thru insulated pex lines.   Could a rocket mass heater be built with a loop of copper lines in the thermal mass of the unit to transfer this efficiently into the house and released to the house by means of a large radiator or two?  Sent to the basement household circulation or natural distribution like that used by pellet stove users employ.   Easily doable or much bigger hurdles than meets the eye?

You could technically do it, but it would be as complex and expensive as building a standard wood outdoor furnace, and probably not a lot more efficient after all the conversion and transportation losses. Not to mention that an RMH is not designed for remote loading but needs to be tended in person. A batch box would mitigate this, but you would still need to go outside once an hour or so to reload it until your mass was fully charged. Speaking of which, where would the thermal mass be in this scenario?
 
It will give me the powers of the gods. Not bad for a tiny ad:
Switching from electric heat to a rocket mass heater reduces your carbon footprint as much as parking 7 cars
