[Greenbuilding] Passisive Solar heat dissipater

[Danny Aerts]

Sanjay,
I don't think having a second heat loop will be any help. The extra piping 
just adds more flow losses while you still only have the same pumping force 
because your heat input is the same as with one heat loop.

Can I ask why you want to put heat into the ground instead of into a water 
tank? Most of the heat put into the ground will dissipate and not be 
recoverable.
