  •  Exactly. and use a ethelyne glycol fluid (0+ / 0-)

    or maybe even a very light oil.
     Use a solar water heater type collector with a large volume. Neck down the external piping to about 1/2 inch and down again to a 3/8 copper coil radiator possibly encased for holding ability.
     Super insulate the external enclosure and all piping with the only heat loss source the radiators.
     I should easily be able to get fluid temps in excess of 135.
     Then run the circulation off of a solar pump for totally free radiant heat.
     I don't want to pull all the underside insulation or I would consider the same system but with floor radiant.
     I have used a passive solar window type of setup and they work well here. I dont see why this wouldnt work even better.
