Modern Heatpumps can be very efficient in the low teens before using secondary heat. For a ducted system the Greenspeed by Carrier is prob the best for this application.

It really does as advertised.
So you have ductwork?
I have that exact heat pump. Bought it 3 years ago I think??? It was the year hurricane Irene hit. It does a good job before it kicks the backup electric heat on. When my old lopi pioneer insert died during the cold spell in January, I don't think the electric auxiliary heat kicked on at all. Now we were keeping the temps in the mid/high 60's, so it wasn't like it was a suana in here, but it didn't seem to have a problem keeping up when the temp was dipping into the low single digits. I like the unit and it really dropped our electric bill since it runs anywhere between 40%-100% of capacity. I rarely see it running at 100%. Plus it is nice when it runs on a low level as it does a good job of circulating the heat from the new pellet insert throughout the house.
