Maybe with the 4000# of metal in the room, the temperature swings won't be too wide.

Right. With all that thermal mass, the room's thermal time constant
should be quite long.


Not counting other losses, the heater being on for 6 minutes will only raise the temp of
the machines one degree. I realize there is more to it but It gives me a feeling that
temperature swings won't be a big issue.

Oh well, I shall soon see how this works out in practice.
