How much would a new 275 gallon oil tank in the basement cost?

Question

This would entail removal and disposal of the old one. Very easy removal thru a garage type door in the basement. New piping too due to modern codes.

Answer 1

A homeowner had one replaced on a jobsite I was recently working at, and he mentioned $600.  I'm unsure if it was just for the tank, or for the labor too, but it took the guys about 20 minutes, so labor can't be that bad.

I would call a plumbing contractor in your area that works in the heating field and get a ballpark figure.
