I like the idea of living off the grid. I did for a while when I lived in a barn in the mountains once. I do have to admit though, that I was not there during the winter. I had a wood-burning stove. It was cold there even in the Autumn.
Stones are one of the best ways of providing heating which lasts for a long time. The stones are heated on a fire (outside) then they have to be put into some fireproof carrier ( a metal bin or shallow tin bath?) and obviously they mustn't come into contact with wooden flooring or flammable materials. A 'stand' can be made out of bricks. Fireproof bricks are best.
Heated stones dealt with safely like this will retain warmth for hours. They can be placed underneath bedding etc (so long as they do not come into contact with flammable things.)
