Koi Pond Heat Source - Takagi T-KJR2-IN Natural Gas Shell and Tube Pond Heater.

Our Takagi Ready To Go Koi Pond Heater Package comes complete with everything that you will need for a simple and quick installation of your own Koi Pond Heating System!

The Takagi TKJr2-IN heat source modulates accordingly and comes with a high volume shell and tube heat exchanger, controls and pump. The pond heaters are designed for your project - the exact configuration is up to you. We do recommend that you assemble and mount your Koi Pond Heater on a 3/4 - inch plywood board, as pictured above and assemble onsite.  Then simply mount the plywood backer board. You are then ready for fuel, power, venting and connection to your pond feed.

Please contact us for sizing as we can offer different Shell and Tube Heat Exchangers than the one show here or a larger Takagi Gas Tankless Water Heater.

This configuation can be used for Pool Heating - although you may want to use an outdoor version of the Takagi T-KJr2-In - the Takagi T-KJr2-OS Gas Tankless Water Heater or a larger Takagi Tankless Water Heater - price will be adjusted as necessary.
