What if solar thermal is fed to radiators, like used for district heating in
EU countries. These large sculptures of Radiart are wall mount or  free
standing so everyone in the room will have a direct line of sight to the
radiant heat input for their bodies.

Will this heat the bodies and not the building? Can you really lower air
temp 10 degrees for the same comfort level? Does it allow turning off heat
in unused rooms like turning off a light to conserve the thermal store?
Since the delivery to the body is radiant, does walking into a room and
opening the valve give you nearly instant warmth?
Anyone have experience with the Swedish building code which mandates radiant
surface temperatures versus air temp. tradeoffs for comfort and energy
efficiency? How low can the input emperature be?

How would this approach reduce the capital cost of active solar with heat
storage?

Just wondering,

Bill
