We have a heat pump for heating. How is it that it’s cheaper to use it than just turn the oven on to warm the house? Also when the heat pump is off it still circulates air.

Your oven is generating all of the heat. Every joule of heat you get from the oven required a joule of electricity
The heat pump isn’t generating the heat its mostly just moving it from inside to outside. The heatpump is just an Air Conditioner pointed the wrong way
It makes the side outside colder where it absorbs heat which can be brought inside then given off to the room on the hot side, the opposite of how you normally run your AC. If your temperature difference is reasonable then the heatpump can add 3 joules of heat to the room while only consuming 1 joule of electrical energy so it can make the house just as warm with 1/3 the electrical energy
The system will also run the fan because heat at the ceiling does you no good when sitting on the couch so you want to keep things mixed to keep things the target temperature at your level instead of at the ceiling fan’s level
