How efficient is this??

in THE MAIN WALL
A convective source installed above AND SEPARATED from the space that must be heated?

Surely the insulation is installed ON TOP of the joist/rafter bays.

Even then, the insulation has to hold back the HOTTEST possible temperatures produced by the system and the COOLEST portion is in contact with the ceiling panel providing heat to the space. Talk about bass-ackwards!!!!

The walls are nearly as ridiculous.

If you're going to heat via convection at least let the air go to the actual space! (My deference here to Hotrod with his test of Ultrafin IN FLOORS)

    I was with a co-worker today and he was describing his hot water heating system. Apparently the builder laid copper fin tube on the plaster and lath ceiling of his home. They have the same fin tube within the walls. It can't be very efficient can it? He has about r35 in the ceiling (just installed about r30 this last spring) But the walls have nothing. He was wondering how to make it more efficient, I said to put in baseboard or even Underfloor pex.

    The poor guy had terrible gas usage last year. And yes the insulation is above the radiating elements, oh I forgot, there is a foil covered reflector over the fintube with the foil towards the fins and then the insulation. He said before he put the extra insulation in the attic he hat temps of over 90 in the attic during the winter. BTW we live in Michigan. you confirmed my thoughts even tho I am just a humble HO.

    Thanks
