My Munchkin boiler was installed in 2006 and went out in 2010. It was replaced with a new Munchkin boiler. The Munchkin warranty says free replacement for the first 7 years. The 2010 boiler went out. My dealer says my warranty runs from 2006 and not from 2010. The boiler was new in 2010 and is defective (heat transfer failure). Many many Munchkin boilers are suffering this failure. I shouldn't have to pay for a new boiler. The new one was 4 years old and failed.
