ThermaKoi Heaters

In the past it hasn't been easy to heat Koi ponds. It meant getting plumbers out to run gas lines or propane lines. Now though with the ThermaKoi line of heaters life just got easy for you and more comfortable for your Koi.

The smallest unit, the 1.5 KW unit, plugs into a regular 115 volt outlet. The 3 larger sizes, 6 KW, 11 KW, and the 18 KW are hardwired (230 volt) into the built in junction box included with the unit.

Made of 316 stainless steel and utilizing highly accurate electronic thermostats, these units keep the water temp constant. Installs easily and quickly. Just plumb in line (2") entering the water at the end with the Safety flow switch and out the other end to the pond. Over load protected and built to last.
