For off-grid RE you heat with heat - IE solar thermal. Run a solar water heater into your hydronics system.
The bigBox places are selling warm floor type radiant flooring that goes into the floor, but they use 120Vac and inside the box is where is becomes useable.
I stop in this weekend and see will let you know. Cheers Bruce S If it is as good as it could be, I would thnk you would need some good sized batts to keep up with the need, but then again if you're home power is out due to storm and this is in and can keep the floor warm from batts and people from freezing? well then it's worth gold.
