In an earlier post, we showed the copper tubing running underground from our new Grow-out Greenhouse to our Nisai Greenhouse.  We have just finished the installation of the new heat exchanger in the Nisai Greenhouse.  Whereas the heat exchangers in the new Grow-out Greenhouse are external to the water, this heat exchanger is set inside the filter pit.  It is a series of coils that are filled with the warmed water, which heats the surrounding pond water.  We installed it in the filter pit instead of the actual tank just so that the koi would not injure themselves if they brushed up against.  The system we are heating contain our BETN koi and our 555 koi.
