Solar Hot Water [RE-wrenches]

[Darryl Thayer]

Hello all
I have had some experiances doing this.  It is not as
simple as it seems.  It is more expensive than you
might think, and it is indeed a place for waste heat. 
What I have done is oversize the Solar Domestic hot
water system and when ever the tank is full divert the
extra heat into the ground under teh basement floor. 
It is not obvious what happens to this heat.  In one
case where the heat was put 3 feet down, we could not
seem to tell a warm up of the soil.  Later it was
discovered the movement of the ground water was
apparently carring this heat away.
