Heating perhaps not so much, it takes a lot of wattage, and consistent supply to run heaters.
If you have some particular application need, such as continual non supply, blackouts, I would suggest slow com stove, or lpg gas back up for heating.
Wind alone is tricky, and in my mind, is near redundant without storage to get that consistency.
I can't remember when I have seen a turbine in use without it, even if it was just a bunch of (or just 2) 12 or 24 volt deep cycles wired in parallel, to supply lighting and tv's etc, on a DC circuit/system.
It sounds like that is what you need, and of course it's far easier to install at build stage than retro fit, but it can be done.
When people don't quite u/stand this, I normally say, "Think of your basic Caravan", .. it has 2 circuits running throughout, one 12V DC, and one 240 AC.
To complete the analogy, it has a 3 way fridge (gas, 240 & 12 DC), and gas cooking, ( & heating - gas oven ) so it can function the same, being connected to 240, or to no more than your car's battery.
A home can be set up in the exact same way.
