I will be building in South Georgia. I plan on using R30 wall SIPS and R50 roof SIPS. It will require very little HEAT, but my concern is air distribution to the rear of the house.

The heater will be in the front right of the wall between the LR and MBR.

I plan on building a new house (~1500 sqft) next year. Can I heat the entire house with a RMH in the living room? It is going to be a shoe box floor plan, about 30x50 (jpg attached). It will be slab-on-grade so I could build the mass under the slab.

The other option is heat the living room and master bed room only with a "Mass wall" between the two room.

Anyone have any experience with this design?
