In the mechanical room there is a pump that pumps the fluid down to the pond and back.
that's the pipes coming in the bottom . The pipes coming out the top go to the geo unit it's self
. That makes one big loop. Now out the other side of the geo unit is two more pipes that go to a 80 gallon holding tank
in this tank the water is kept at whatever temp you have set at and the geo unit keeps it at that temp. There is also two pipes off the geo unit that go to a domestic hot water tank that is a bi product of the geo running.this is all my geo unit dose.the In floor heat has its own controls and pumps that run off thermostats to keep the heat on.
. In my house I have four different zones, the house, wife's garage, man cave, and the shop. This way I can keep them all at different temps.
