When backyard ponds ice over, harmful gasses from decaying plants, algae and fish waste cannot dissipate. Thermo - Pond heater creates an opening and allows the gas/air exchange that keeps these toxins from building up. Fish stay healthy all winter long.
Thermo- Pond Heater floats on top of the water and is thermostatically controlled to never get hot. Will never burn a pond liner or plastic pond. The heating element does not touch the water, so there is no build-up or crusting of the element.
Completely enclosed in ABS plastic with gas-exchange design. When temperatures exceed the ability of the unit to create ice-free space around the Thermo Pond, the unit itself facilitates gas exchange right through it.
First energy efficient pond heater! Operates on only 100 watts - 12-15 times less power than other leading brands. So efficient it pays for itself in as little as 2 months. Cost as little as $2.00 per month compared to other heaters which cost as much as $35 per month.
Tested in the Northwoods of Wisconsin at temperatures dipping down below 30 degrees below Zero F.

Note: We recommend more than one Thermo Pond for ponds over 1000 gallons. Additionally, ponds with heavy fish load or heavy organic plant decay over winter will need more gas exchange than very clean ponds with minimal fish. Order more than one unit for larger, heavily fish loaded or heavily planted ponds.
