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
