"Piece of crap"

Very Unsatisfied

We were talked into the Munchkin Contender and it was installed in the summer of 08. It vibrates and makes a pounding noise that will wake the family up in the middle of the night. Wish I kept my old boiler. Our installer doesn't return our calls anymore. This is just a piece of junk…….
