One consideration is that the electric fireplaces provide you will flexibility to heat just the room you are in. This would clearly be applicable to the bedroom. For example, you could turn the heatpump down at night and use the electric heater in the bedroom. I have three options in my house, propane central gas, heat pump, and electric baseboard. I use all three at different times and in different places in the house.
Yea .. I forgot .. I have a propane driven fireplace but I decided to give it up because the propane has gotten too expensive.
