<p>The occasional bit of smoke that might get out during loading the stove is natural in nature and won't hurt anything unless you have a prolonged exposure. More likely to be bad for your lungs than the fish or plants if such a long exposure persists for weeks or months. In other words: NO. Been heating our AP GH for 3 Winters and all is very happy.</p>

<p>I have been heating our gh with wood thru some very cold (20F) nights with my home made woodstove for close to a month now. I have a 6 ft x 3/4"SS loop that heats the sump water and will install another on the other side soon to heat a hot tub. The more thermal mass the better. I am now running about 1800 gal and I can raise that about 10F in 24hrs so maintaining Trout temps at 50 - 60 has been easy. Here is an old PIC!! I'll try to get some current ones today.

<p>Under the floor, if you can retrofit, would be the best. In my green house it has concrete floor already so I'm making clay bench that will support fish tank on top of it. It's only 18 inch high or so but that gives me plenty of mass for heat retention.

<p>It does create a lot of heat around the heater itself. Make sure you insulate around the heater. Lumber and others can catch fire even from feet away if you don't insulate the burner. About 6 ft - 8 ft of 2X4 scrap lasted about 3 hours. I'm calculating this would be enough heat (once the heat mass is heated up) to keep the space warm at least half day. </p>

<p>You probably could still to a RMH but skip the zig-zagging of the exhaust through the mass and vent vertically. You would lose a bit of efficiency, but it will save a ton of space.
