Most air supply heat pumps grow to be much less efficient in out of doors temperatures decreased than 4 °C or forty °File.[54] This can be partly simply because ice forms to the outside device's heat exchanger coil, which blocks air movement above the coil. To compensate for this, the heat pump procedure ought to briefly switch again to the normal air conditioning mode to switch the out of doors evaporator coil again to your condenser coil, to heat up and defrost.
The icing problem gets far more significant with lower out of doors temperatures, so heat pumps are sometimes set up in tandem with a more conventional type of heating, including an electrical heater, a normal fuel, heating oil, or Wooden-burning fireplace or central heating, that's utilized in lieu of or Besides the heat pump all through harsher winter temperatures.
