Lets do some horribly rough math to find out... Feel free to tweak the numbers as I'm really just guessing.

Say you get to use the heat pump for 4 months out of the year in heating mode. Over those 4 months you'd normally spend $60/mo on gas, instead you spend $20 on electricity. So you save $40 * 4 = $120 per year. $1000 / $120 = 8.3 year ROI. Thats actually not as bad as I thought it would be. But, as I said these numbers are really just wild guesses. You'd probably be better off spending $1k on sealing up the house and adding insulation.
