Karen Briggs : The whole unit is an incredibly efficient space heater, that can, if the house is compact and has an open type stairwell easily handle a small bedroom and a bath as the primary heat source, your layout is almost certainly wrong, to use this system you need to be close-by to feed the dragon that lives in your rocket stove frequent small meals over 3-4 hrs, to give you 20-25 hrs of heat , this basically means someone gets to be a homebody, not a bad thing just not practical for a lot of people !
