This is the geothermal stuff. It comes in a ball and rolls out in this pattern. David says to tell you it is a refrigerator backwards. You bury the pipes in the ground deeply and the ground warms the liquid in the pipes to about 64 degrees. This goes into a pump and the heat is transferred in a closed system to the loops of underfloor heating pipe. (We have to top up that temperature with some electricity to make it warmer.) It heats the water for other household uses too.
