Really ** I put this little heater solar hot water together in order to reduce the electric bill to heat my tanks Aquaponics. You can read here: Video Rating: 4 / 5

  2. Hi!
    I’m also an AP gardener, and this is exactly the kind of thing I was looking for. Thanks. How did it work for you?
    Also, the link to your blog is misspelled. I figured it out and subscribed on my reader, but I thought you’d want to fix it here.

  3. One thing I would be careful of is using hoses and tubing that isn’t NSF or designed for potable water. Typical garden hose contains all sorts of chemicals that you do not want to be ingesting nor do you want to introduce to your plants and fish if you are planning to eat those. A safer way is to create an heat exchanger where it has a stainless or appropriate coil to transfer the heat into the fish tank. Certain types of copper tubing can be toxic to fish so do research before using copper.

  4. Located in North Texas with temp in the summer of 100+ and temps in the winter of 20 degrees and above. I looked at closed loop systems and decided the direct approach was best for my needs.

  5. I have looked at using VAWT wind turbines and will probably pursue this option sometime in the future.With the use of one water and air pump, my electric bill has only increased by $12 to $15 per month, so I’m not sure if the expense for a wind turbine is warranted.

  6. The plastic can fail if it gets above 140 degrees inside the solar box, but I haven’t had that problem yet. I am currently using clear roof panels on the front instead of glass which is only giving me an approx. 4 to 8 degrees rise in temp. With glass I will probably get a 10-15 degree rise, but I won’t know for sure until I replace the plastic with glass sometime in September.

  7. I’ve heard the plastic fails. but what kind of water temp change did you get out of this system. I getting ready to set up my AP system and this is on my mind for wintering over. I live in southern Arizona so its not as drastik as some places but the winter does bring temps below freezing at night.

  8. i noticed you said you have high winds. You might look into using wind turbine to power system.

  9. You could put one of these before your water return to bump up the O2 in the water.

  10. compost creates a good heat source also.

  11. Nice! Where are you located? Curious about the climate you’re using this in. Been thinking of doing a similar heater myself. Had thought about a closed-loop system rather than pumping the fish tank water directly through the heater, but your direct system is certainly simpler. Any thoughts about that? Best wishes and I look forward to any updates.
