<p>Thanks TC. Florida and Tilapia are still an issue? Wow, I should be so lucky as to have your problems :-))</p>

<p>Thanks for the advice I'' certainly look into some reflective boards.</p>

<p>The water might make a handy thermal mass for the really extreme times but yes, you want to warm the air and insulate the greenhouse to an extent if you really want to keep tropicals growing through winter. I've seen some greenhouse lean to or A frame designs that have the reflective boards that can lay down from the greenhouse by day to help reflect more light in and then you flip them up to insulate the greenhouse as evening comes on. This is great provided you are always home at dawn…</p>

<p>Hey Dusty...just one more thing to think about in reference of your OP...</p>

<p>If the air in the greenhouse is colder than the water in your fish tank(s) you can pretty much look forward to lots of condensation...which may do funny stuff like freeze the greenhouse door shut so that you cant get in there (hasn't happened to me personally,…</p>

<p>Ahhhhhh Of course, I forgot the fundamentals Vlad. Thanks for reminding me. I cant use hot water going through copper pipes heating the fish tank water, because dem fishies deh don't like copper :-) </p>

<p>Wow that pellet stove looks awesome, I'm certainly going to play with a few ideas.</p>
<p>I'll keep you informed.</p>
<p>Thank you guys, you saved my brain from getting fried thinking of idea to do this. Very helpful. </p>

<p>Keep in mind that you don't want any water that has been in contact with the copper getting into your system (or your heating might be all for naught). Rick's pellet stove (really cool btw) I believe uses some sort of exchange mechanism so that no copper is ever in direct contact with any system water.</p>

<p>As far as "is 1000Watts enough" it really depends on your delta-t....How cold the water is, how cold the surrounding air is and the temperature difference that you want to achieve (and of coarse volume of water). Unfortunately when you design these things out you usually need to design them for the most extreme situation that you expect to be in (which sometimes seems silly to invest and pay for all that, for an event that may happen to last less than a week out of the year, but if you don't...you might (probably) get screwed...</p>
<p>There are some charts from AES I have lying around somewhere which might help give you an idea of sizing out the heaters...if you don't already have something like that, I can dig them up for you...</p>

<p>I use a 1000w bucket heater to heat the spa up, its about the same gallon wise as an IBC. In fact the built in heater only uses 1000w in 120v mode. Its fairly well insulated though and it takes several days to warm up in our 40-50 degree winters.</p>

<p>A member (<a href="http://aquaponicscommunity.com/profile/RickStillwagon">http://aquaponicscommunity.com/profile/RickStillwagon</a>) recently was testing out a pellet stove for heating IBC tank(s). I am not sure what your conditions are specifically but I would think that insulating the tank very well is worth the investment over more wattage in terms of heaters but still not sure if 1000w is enough. Also keep in mind the grow beds themselves can influance the water temp a lot. When it is cold, you may want to try constant flood over flood/drain to minimize the media sucking all the heat out of the water as it is filtered.</p>

<p>Guys thanks for your responses. I will certainly look into the heating jackets Vlad. Yea ideally changing to trout or koi would be great, but I have these little guys (fingerling size) that are won't nearly be big enough to harvest before winter. So gotta prepare now for the cold.</p>

<p>Chris, they're only very small at this stage and when they do start to get bigger, I have another two IBC's on standby</p>
<p>If the three IBC's are in use when winter arrives I was thinking of a rocket stove heating a 55 gal drum of water with copper pipes in the water going to sump for the fish tanks.</p>

<p>200 Tilapia in a single IBC tank system sounds like too many. How big are the grow beds? How many cubic liters of media total?</p>
