how the heating element works in heatpump system

11 years ago

My old heat pump does not have the heat strip, only the fan and the evaporator inside the air exchange unit. The new unit includes a 15KW heat strip element.

I read some where that during winter, when the outside temp below 25 degree F we should use the heating element instead of the heat pump in order to get the warm air output plus saving more money in electric. Is this statement correct?

The thermostat has 4 setting: Cool, Off , Heat, Emer. Heat.

If that is the case, then what I should do with the setting
