What is a Heat Pump Clothes Dryer?

Heat Pump Clothes Dryers extract moisture from your clothes by circulating warm air within a self-contained system, eliminating the need for an exhaust vent.

The Technology

How It Works

  • The clothes dryer is powered by utility-supplied electricity or by solar electricity if you have solar panels
  • Electric condenser coils heat air that moves into the dryer’s rotating drum
  • Hot air that contains moisture from the damp clothes exits the drum and is cooled by evaporator coils
  • Moisture drains away through a hose or collects in a removable tray for you to dump out later
  • The cycle begins again with condenser coils heating the air that enters the dryer’s drum
