[VAC] Re: foam tank support

Twenty pounds sounds suspiciously heavy.  Are you
certain the material in question is the original?  I
have a photo of mine which I could send.  Email me
off-list if interested.

Here's the main problem with replacing the original:
you must allow for the function of the heating system.
 The original foam supports the tank on lots of
cylinders with air spaces between them.  This allows
air to circulate beneath the tank.  Hot air is
supplied under positive pressure from the furnace.  If
you put flat foam under the tank it will prevent this
air circulation.  In addition, the tank bottom is
sloping, so it won't match the contours of the tank
bottom.

Perhaps your foam isn't original.  It seems unlikely
that the original material could absorb so much water.
