ParticipantYes. A heat pump is 3x to 4x as effective as straight electrical heating in San Diego’s climate. As the outside temperature approaches 0 degrees Fahrenheit, it gets less efficient than straight electrical heating. You need to look at the unit’s energy efficiency ratio (how much energy it uses to move a specific number of BTU of heat) and compare the cost of electricity with the cost of what ever fuel you are going to use to heat the house. Because of how heat pumps work, the energy used to move the heat energy from outside to inside also contributes to heating your house (This is why heat pumps will almost always beat straight electrical radiative heating).
Also look at Ground Source, or Geothermal heat pumps..

ParticipantI have a friend who is installing a Geothermal heat pump in a new house. Made sense given a new construction project on a huge house. Not sure about viability as an “add-on” project.

ParticipantI’ve seen some that will also cool the house. Are there any disadvantages to this? Does it make the heating less efficient? BTW I’d be installing this into a 900 square foot house. I was thinking about doing a single station and then adding more in the future. Does this make sense, or should I do everything at the same time?
