Here are a few photos of our setup on one of our Nile pools. We have similiar setups on all of them. The heater is in one photo and the other photo shows an 11ft female Nile at the waters surface on what was a 20 something degree day.



We where able to maintain very good water temperatures so that the crocodiles where able to swim normally. When crocodiles become to cool they 'list' to one side and eventually drown. We usually see this when the water temps drop below 50 degrees with Niles. You can see the female sitting with the correct orientation despite the freezing air temps.



The heater kept the water in the mid sixties to the lower 70's even on the days when we had a quarter inch of ice on numerous ponds without the heater. In a smaller pond we maintained temps in the 80's. It felt like bathwater. The pond in the photo is approx 50ft long and 25ft wide in spots with a depth of 4-7ft. That much water is hard to maintain at 80 in that type of weather so we look to make it survivable first livable second. We would have lost numerous animals to this front without them.



At the end of the season we just pull the pump up, remove the pipes, and move the heater. BTW we use the bucket to keep debris off the pump. It siphons the cooler water from the surface and the return sends heated water deeper into the pond creating a nice warm undercurrent. The water returns 3-10 degrees greater than it enters depending on the size of the fire I have going. We also use a chemical 'pool' blanket to retain the heat we put in the pools. It is very effective.



At the end of the front we lost zero crocodiles and it was a bad rare front so I feel the heaters really proved their worth this time around.
