Greenhouse New Thermal Mass Tank 275 Gallon IBC Tote Hydronic Heat Exchanger Raspberry Pi Controlled

In this video I show and explain my new 275 gallon tank as thermal mass. I use a low power 12 volt circulator pump, a Raspberry Pi, thermal sensors, and some python code to turn the circulator on and off. The circulator uses a copper coil as a hydronic heat exchanger to capture heat from the pot on the wood stove to the thermal mass storage tank. The thermal mass storage tank releases it's heat over time, thus regulating the greenhouse environment especially for cold nights in the winter. The Raspberry Pi also acts as a data collector to collect data from the greenhouse which is captured to a database and charted on my home computer via MySQL and PHP.
