Re: An Aroid greenhouse question

Gary, I would like to hear more about this
system....even though I don't fully understand how you've got it set up.
your chest freezer outside or inside?
Sorry that my explanation was so lacking in accuracy. The tank is
inside the greenhouse, and sits on the floor in about the center.
This tank was the inner lining of a chest freezer that I stripped of the
outer metal skin, and all of the insulation. I then washed the
outside with TSP and detergent, rinsed well, and sprayed flat black to
absorb the sun's heat. I did put the tank on a section of 4"
rigid wall insulation trimmed to fit with a knife, to prevent loss of
heat into the substrate. Additionally, I use a small infrared space
heater ($16 at Kmart when I bought it in Oct., '96) that is propane
fired, placed 1 foot away from the end of the tank and aimed directly at
it. This is only fired up when the temperature drops below 45
degrees more or less, and works great. The heat that is absorbed by
the water through the tank walls is even and more equally distributed by
radiation rather than heading straight up.
I have an economical method of keeping the water temperature even
throughout the tank at all times, but don't want to bore everyone with
I can draw a diagram and scan it, but being rather new to this dumb|
machine, I'm not sure how long it will take me to figure out how to post
it. If you are in a hurry, send me your snail mail address and I'll
send you a copy.
Someone did mention that the longer the stove vent pipt, the more heat is
captured. Be careful though, the exhaust gasses must be hot enough
to be vented out. Building codes are based upon these requirements
for safety. The non-vented greenhouse heater is an easier and
better ( in my opinion) way to go. I also keep some livestock in my
greenhouse in addition to the fish in the tank.
Keep having fun! Gary Meltzer
