might 3 of these heat an 800 gallon aquaponic system in a greenhouse or is there a better way

I believe they make bigger ones but this one alone heatheats my 240 gal this with sump in garage at 80 degress perfectly.

pretty sure it will do the trick. Go with 4 and make sure you have some power heads in there to move the water around a little

I would expect to need to power the independently, with individual thermostats. That said, it really depends on the power capabilities of the thermostat vs the power requirements of the heating mats. As long as the thermostat is rated for more watts than the attached matts are drawing then you will be fine, but most of then are not designed to run more than a single matt. Also you would run the risk of one matt being hotter than others and burning your seedlings, as you only get one heat probe per thermostat.

This will work, I used it to do something similar for my greenhouse. The only problem is that the wiring diagram that comes with it is wrong. You will have to either go through a trial and error process or email the company and insist on sending you a diagram that works and is accurate. I had to email them twice to get an accurate diagram and as they do not write english well, it can be trying.

I'm not sure, I have a 250 watt for 90 gallons which I am using in an outside pond - totally under water. And it's doing great. You really need to call a pet shop for the answer - sorry. Even if the wattage is overkill, it's oK ; it will not come on pass the setting you set. So if you set it on 76 degrees and the water in your tank is 78 degrees it just won't come on.

Yes, will definitely work super in a 55 gal drum! Mine are plastic trash cans no less, not even metal. I have two heaters and rotate them among about eight drums in the greenhouse until I get more heaters and then will put them on timers. Have not kept exact records but my tap water is about 52 degrees and these heaters will raise temp about 10 degrees an hour to over a hundred no problem. I am at 7200 ft in the Rockies so the heat is needed!!Best of luckcoloradobluej@gmail.com

I use them for hydroponic gardens and i set them to come on for 7 minutes 3 times a day till the weather gets hot then i add a couple of more times a day.

Solar panels produce anywhere from 1000 to 2500 BTU's per square foot, per day depending on your climate, (northern, southern, mid). These panels are rated at 2 square feet, so 2000 to 5000 BTU's per day, depending on location. 1 BTU will heat one pound of water by 1 degree fahrenheit. A gallon of water weighs 8.33 lbs, so you would need 8 BTU's to heat 1 lb of 70 deg F water to 71 deg F. The water in your pool weighs 19,800 pounds. Just to raise the temperature of your pool water by 1 degree you would need at most 9 panels, or at minimum 4 panels. From your question it looks like you want to raise the temperature of your pool water from ambient 68(70) to 89(90)? That is a 20 degree delta T, so realistically you are looking at a 396,008(400,000) BTU load to keep your pool at 90 degrees during the summer,(which to me sounds wayyyyyy too hot for a pool). At best, producing 5000 BTU's per day from each solar panel you would need 80 of these panels to maintain temp. If you wanted your desire temp to be 80 deg F instead of 90 deg F than you would need 40. Someone correct me if I'm wrong. There are pool specific solar panels that might produce more BTU's per square foot of usable solar area. In my opinion, 80, or even 40 of these solar panels sounds a little unfeasible. Yes, you could do it, and it might be cheaper than purchasing a 400,000-500,000 BTU gas fired pool heater, but realistically it's not a good application for these specific panels. The common solar panel size to heat water for domestic hot water in households is an 8x4 which they rate for 40,000 BTU's. For those you would only need 10, but again might be a bad option, as they are large, and are quite expensive given their size, (usually 800-1400$/each). Hope this helps. PS. I am also not a pool expert. I am not sure on the thermal retention that pool water holds during the night. It could drop 1 degree in 10 hours or it could drop 10 degrees in 10 hours, I really don't know.

I used two for a 200 gallon aquaponics tank, with a timing of 5 minutes on 5 minutes off. They put out a lot of volume. I would think one would be enough for an emergency.

I run this in an aquaponics system (plants and fish) No issues for a year+. I think we're safe

You would need the 5 watt size for a 1.5 gallon tank. This one would be way too warm.

the temp will be just a little warmer, but that is with sun light on the unit. They are not make to replace the glass greenhouse, just to help you get started a little sooner.

We live on central coast not to cold but the frost does show up some winters would like to know how to heat the greenhouse

Im not sure. Ive recently switched to led for vegg. The 8 bulb fixture raised the temps almost 15 degrees and sucked out every bit of moisture. If u have a very large space its not a problem. It was for me tho.

Unknown I use a 500 gal tank but it would depend on outside temp and how warm u wanted it I have a friend who had a old style unsafe heater and he got another one I had because what he had was so dangerous. It is a great heater I have 2 30000 btu heaters also in my barn they are great I highly recommend them

I would not. I use a 400cfm blower with a separate 250cfm booster (both 6") to keep my tomatoes from heat growth stunting & my 1 bulb is only 600w hps with a separate 400w led. Keep in mind, the air flow has to go around your 3 mogal bases slowing the air down and a carbon muffler odor scrubber that slows it down even more, in addition to the ribs of flex ducting posing air resistance. If you try your setup out, don't be surprised if the last 1000w in the series burns up, not to mention your stunted plants/ruined.

They can get well over 120* F, They WILL burn reptile feet and bellies if you do not have them plugged into a Thermostat controller
