When we had out Design visit last May, adding the hot water recirculating loop was an option, for a not so small $8,500 fee. I was told all hot water lines were also insulated, in that option. Also, I would hope any lightly buried water lines are not sitting in water! Under any slab! Should be very dry under the slab.
