Removing 40 yr Old solar tank

Solarstar Member Posts: 82
Was cutting it apart to get the weight down (400 pounds) and was totally amazed at the internal condition of the tank. Very minor scale /buildup  . the internal lower copper heat transfer coil was almost  new with very minor scale as well. the Electric element was never wired up.    Paul

Forgot to say its a Ford Stone lined tank...

    Why did you remove it?

    Was it leaking?

    Re tank cutting

    Hi  HR: I cutting it into 2 foot sections with a thin kerf 5" grinder wheel , to my surprise the actual metal is quite thin ,then a couple hits with a sledge and it breaks cleanly on the cut line thru the 5/8 inch layer of Concrete.   Paul

    Re : why tank removal

    Hi Kevin : Yes the  internal coil had developed a pinhole leak of some sort ,but no external tank leaks at all .In the day these were one of the best tanks out there . Now running my Evacs into a 120 gal dual coil ss tank and a Smart 40 I'm working for overflow (temp). All pumped by a single 20 watt  PV  DC pump which provides nice linear /proportional control..... with 8 people in the house we use lots of water.   Paul
