Benefits of Heat Pump Clothes Dryers

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.

Lower greenhouse gas emissions

Less polluting than conventional dryers

Save money

Energy savings of up to 60% compared to a conventional electric dryer


Compact design and no need for outdoor ventilation make it suitable for almost any living space

Easy to install

Plug it in to the same outlet you’d use for a conventional electric dryer. No drains or penetrations through the wall are needed.

The Technology

How It Works

A heat pump clothes dryer is powered by solar electricity if you have solar panels or utility-supplied electricity. Electric condenser coils in the dryer heat the air that moves into the rotating drum. As the cycle runs, the hot air absorbs moisture from clothing. When it exits the drum, it’s cooled by evaporator coils and the leftover moisture drains through a hose or collects in a tray.
