Your dishes are cold becaue they are inside a closed cabinet on an outside
wall... adding extra insulation would not have made your dishes stay any
warmer, becaeu it's thje heated air inside your house that warms those
dishes, but being in a closed cabinet the house air can't get inside the
cabinet at a high enough rate to offset the refrigeration of the outside
air. This is why plumbing is supposed to be inside an interior wall.

It's not to heat your house, it's strictly for the convenience of drying
your dishes and for health reasons... if having to wait for your dishes to
air dry from the time you open the dishwasher door is not inconvenient to
you then by all means don't use the heated dry... only negative then is that
your sysem is less sanitary.. dishes really should dry as quickly as
possible, stagnant water is unsanitary.... sometimes restaurants become
backed up and they serve in wet dishes, that's a big health code
violation... purposefully air drying dishes is a much bigger health code
violation.
