From a theoretical perspective, the most efficient way to heat a house with wind is to have a windmill gather torque which drives the shaft of a heat pump.
From a practical perspective, Ryland is right: the good wind is up high, and wind power is best left to those with >100ft towers. It's not as fun, but my utility lets me buy wind power for $0.12/kWh, which is FAR cheaper than I could generate it myself.
