If you are looking for supplemental heating in an area bathroom or under your feet in a home office, for example, electric resistance heating below a tile floor is quite comfortable, if not a bit luxurious.
Given that your new home will be fully electric and your interest in warm feet, I recommend you consider a geothermal heat pump that has the dual capacity of forced air (for heating and cooling) and connections for radiant heat loops. A geothermal heatpump is very efficient and, for me, the best way to have an energy efficient system in an all electric home.
An example of this type of system is the Synergy3D by Waterfurnace.
- It is designed to combine both radiant heat and forced air.
- Whether you choose to use radiant heat in small zones like bathrooms and the kitchen, or in larger zones like the basement floor, this system can meet those goals.
Note: Look to Energy Star for their recommendations on home insulation levels and good air sealing practices too!
