In some cases they use a high thermal transfer grout to surround geothermal ground lines, I am thinking this might be a superior product to use for Hydronic heating or cooling.

Since they go to the trouble to use a high thermal grout to surround geothermal lines would it be worth it to use the grout to surround the lines in the floor heating circuit or a refrigeration cooling circuit ?

I could use opinions on if concrete will be just as good to use as a thermal grout for cooling in my case but I think it would apply equally to heating.

I am making a line imbedded mini refrigeration unit and want it to function well.

I want to hear concrete would be just as good as its easier to get but I would seek out and get the thermal grout if its deemed worthy.

educated guesses or opinions would be helpful as I am winging it.
