Heating a greenhouse

Hydronics, Radiant & Water Heating
1

Hi this is my first post, I am in the process of building a large, 20000sq ft, greenhouse and would like to use a radiant heating system built into the floor. My plan is to run 4 grids for different heating zones inside the greenhouse to allow for certain plants. The goal is a consistent temperature around 21-24c.

My question is on whether a water loop for hydro cooled miners would compare with an immersion setup. The winter temperatures where I am rarely dip below 0c and I am in the hardiness zone 7/8

Other suggestions are welcome. Everything is appreciated.

Immersion vs hydro cooled shouldn’t matter of the radiant system. Either should be considered a “boiler” in the setup.

With that being said, I’m going with a hydro heatCore system so I don’t have to deal with immersion fluid. It sounds like you might have a non-residential setup where adding an immersion tank might not create additional overhead.
