Warren!�� You mentioned your plan to lay copper tubing heating loops in 
your concrete floors.� Make note and check out carefully how to do this 
plumbing.� Back in 1947, after WWII, my father had a lawyer friend that 
built a brand new on slab home and had the copper tubing loops in all 
the floors in the house. Great layout for it had a gas fired central hot 
water heater and Grundfos recirculating pumps off a central manifold to 
control the flow to each room.� All ran well for about 5 years, then the 
walls starting to mildew, especially in the various closets. When they 
jack hammered a section of the floor they found that the lime in the 
concrete along with some galvanic action had eaten away the copper 
tubing and leaks were everywhere. Ended up abandoning the whole floor 
heating system and went to central heating furnace. Some one should be 
able to advise you on this problem.� Maybe the type of copper??� Maybe a 
problem of not having a (- negative) charge on the copper?? The long 
haul natural gas transmission lines have a DC power supply that they 
potentialize the entire line with a low voltage negative (-) charge to 
prevent erosion of the steel lines. When submerged in water they have 
the sacrifice zinc plates like you have on your boat.��� Just a 
cautionary note.��� Norm
