Thermo Pond Heater
The world's most energy efficient pond heater for ponds up to 1000 gallons. For just pennies a day, it will keep a much needed air hole in the ice of your backyard pond. A healthy pond needs to have a breather hole in the ice to exchange gasses. If you need to use this as a submersible heater, it can be used with netting. Please make sure your pond wiring is safely done. 4 x 4 x 12 inches.
