What do you want to do? You can wind any stator for 110 or 220v, you just use thinner wire.
You will not get more power at the higher voltage. At the high voltage it seems unlikely that you are intending to use batteries so what does voltage mean. normally the batteries define the system voltage.
The output direct from a wind generator is wild electricity with voltage and frequency changing with wind speed.
The thing is too small for useful heating so I don't see what you will do with the high voltage.
