This - we've got a brand new Daikin heat pump at 10F/-12C outside temp, it took full 24 hours to bring our place from 50F/10C to 72F/22C. A regular nat gas furnace would knock it out in about and hour and half, and at fraction of the cost. Incidentally we're in the process of installing a nat gas tankless combi heater to address this issue - you can get a forced air set up with those.
