Your fish can't live without this pond heater

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. This pond heater 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 a 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 Fahrenheit.

  • New Thermo Pond Heater 3.0 Features:
  • New 12 foot cord with increased strain relief that is well beyond UL Listing requirements.
  • New thermostat with faster response to temperature changes. Increases the unit's life by years. Has more "On" cycle time.
  • Larger hole in the ice which allows pond owners to know it's on at a glance.
  • Leak-proof entry port injected with two-part epoxy eliminates possibility of leaks.
  • Upgraded plastics exceeds 2004 UL Listing standards.
  • One year limited manufacturer warranty.


Note: The manufacturer recommends Thermo Pond heater for ponds up to 1000 gallons, please purchase 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.
