Can you have a heat pump installed and have natural gas burner at your house? Kind of like play which ever one is cheaper or functioning based weather outside? My house is 25 years old. Not sure how well insulated it is. Would be nice to be able to rely on whichever source happen to be cheaper at the time as well as switches to the other if Temps dip into the negatives.
