It sounds like you already have wind, and storage batteries with a converter will handle your lighting. If you decide to generate your electricity with steam, you will need a small high pressure boiler system separate from the low temp radiant heat system. It requires high temperature steam with at least 80 psi of sustained steam output to run a turbine.
The biggest advantage they provide is, they are easy to work with, repair and maintain.
NOW that sounds interesting. I’m def going to look into a wood boiler. We have in floor radiant heat already in the basement and first floor of the new part of the house. We added onto an old log house. It’s amazing the center of the house is now the old log house. In the summer unless it’s hot for many days, that area stays nice and cool.
