[EAS] a note of interest

A 20 should be enough to run the studio in my case--at most
a 30 to handle heat/air. We'll have to do a close check on
the load before we get the geni. The transmitter site will
probably be propane--the load would be an ECO 4, maybe
someday another transmitter for a 2nd station, but that's
speculative at this point. The building has HVAC for the 25
X 40 transmitter room portion, but that will normally run at
a minimum level--there's no-one there, of course, most of
the time. 

We actually have natural gas at the site--including a well
(not mine-sigh! Didn't get the mineral rights). But that
would be a rather dicey source.

You do need to consider staff comfort. At our combined
studio/xmtr site we have 3 phase power for our B-1. When we
sized the geni we decided not to try to run the 10, but
instead just use the 2.5K we had for a backup.  Based on
past experience we also assumed no more than a day or two of
backup.  So we ran critical circuits to a single phase
sub-panel, leaving off the 10K, and the heat pump.

This worked well enough--the 2.5 K was plenty of power to
cover our COL, and the small studio building (35 X 50) was
well insulated enough that even in winter it stayed
comfortable (low 60's) even after a 21/2 day outage. 

The Derecho was another story. After the storm it got hot,
and soon very uncomfortable.  A window air conditioner would
have been very useful.
