How large scale can a rocket stove be? 1500 square foot possible or nay?

Hi all,

I'm planning a home for the first time in my life and hopefully the last! We want to make all the right design and sustainability decisions now while we have everything as a possibility.

I've been looking through lots of designs for rocket mass heaters, and I LOVE the concept. It would fit so well with our very much off-grid home, but I'm having trouble envisioning the actual heating power for a large space, as most of the thermal mass I've seen is a bench or day bed style in a single room. Could a rocket mass heater be designed to cater for a full sized family home, perhaps by heating the concrete slab it is built upon? The footprint we're working with is actually a recycled barn frame with 1500square foot floor space but a couple of high bedrooms and a playroom in the loft areas. We're planning a huge fan for the purpose of air circulation, so if the slab could be heated well then I believe we could circulate the air well enough to avoid losing all the heat into the rafters. Could this also be incorporated into heat for cooking and water heating, or would I just be dreaming then?

I'm aware I can hire experts to help me with the design when it comes time, but just a general idea of whether it's even feasible would be very helpful!

Thanks for any advice and help!

I grew up in a two story house heated by air channels from a single fire place.
No fans, air only moved by heat.
The house was designed and build for this.
1500square foot floor space should be possible in such a way.
