I've forgotten my physics...any one... what's 30KW in BTU?

According to a formula I found at "infoplease", that works out to 102,360
BTU.

Coffee is only a way of stealing time that should by rights belong
to
your slightly older self.

My 75K natural gas unit heater costs $1.00 per hour as a comparison.


Depending on what I'm doing I keep the shop 28 X 40 at 70 to 72
degrees F for about 12 out of 24 hours with the other 12 at 62 to 64
for about $2.00 to $3.00 a day in this very cold weather and it's
75,000 BTU as well. Of course it's not running all the time.
