During the cold winter, Koi stop eating and live off their fat reserves, lowering their immune system. As the water begins to warm up, bacteria become active, and Koi can be in trouble. Keep your Koi strong all winter by heating your pond, keeping your Koi feeding consistently.
In the past, heating Koi ponds has meant running gas lines or propane lines out to the pond. Now with the ThermaKoi Heaters, you can have pond heating wherever you have electricity! Made of 316 stainless steel and utilizing highly accurate electronic thermostats, these units keep water temperature precisely controlled.
