  That's what I had in mind. My 3/4 HP variable speed furnace fan is 
rated at 6.8 FLA so most transformers I've seen won't handle the 
current. Rewiring the motor isn't an option. Also, there may be other 
electronics involved that require 240 since the system produces a 20 Mhz 
whine in my SW receiver whenever it's running. My little Honda EU2000i 
generator only outputs 120 volts. I found a transformer on eBay that 
should work but it's far larger than I need.

  An alternative I'm considering is a small diesel generator with 
120/240 output. I already have a 280 gallon tank for my oil fired hot 
water heater which also serves as the backup heat source for the heat 
pump. The advantage is I don't have to stock gasoline.
