My house is all brick with 2x6's and full basement. Ceilings are standard 8'. Not as big as yours and probably use twice that amount of propane. Full insert fireplace with blowers will heat the whole house but if you want it comfortable in the back rooms you have to supplement with propane-and you could wear yourself out cutting wood and probably never vary by more than 100 gallons. Built in 1980. Mine is very well built but needs about 100 grand in renovations.
I'd like to build a native stone house in the Hill Country style.
