Hello all (again)
       On the subject of heating,
 I used to breed fish and this required a spare tank to
 keep the young in. To save on cost a did a 
short experiment with incandescent strip lights. Onr of these four 
inch blubs was enougth to heat the water in the tank far above that 
which the young fish required so I used an old thermostat (you could 
once by them seperate from the heating element) and this would turn 
off the light at the required temp.
      I read about heating a south faceing greenhouse by filling 
black water drums and stacking them against the north side of the 
green house. The sun shines through the glass onto the black plastic 
which quickly heats up and heats the water inside. At night the warm 
water slowly loses the heat back in to the green house.
Yours
