How do ductless systems work?
Unlike standard electric heaters, which create their own heat, ductless systems pull existing heat from the surrounding air and use it to heat your home. They also reverse this process to cool your home. Ductless heat pumps distribute warm or cool air more quietly and efficiently than traditional electric heaters.
Ductless heating and cooling systems are reversible, two-way heat pump that simply take heat energy from on place and move it to another by compressing and expanding refrigerant. There are three main components:
1. Outdoor unit: connects to the indoor unit by a small bundle of cables, including a refrigerant line. The unit is placed outside of the home on ground level.
2. Indoor unit: mounted on a centrally located wall. One indoor head is enough to heat and cool an average-sized Northwest home.
3. Remote control: allows occupants to adjust the settings for maximum efficiency, comfort and control.
Installation is quick and easy. There is no need for expensive, invasive and often leaky duct work: A small 3-inch hold hidden behind the indoor unit is all that's needed to connect it to the outdoor unit. Ductless systems do best when they are installed in a central location in your home. They work with your existing heating system to ensure that bedrooms and bathrooms are the perfect temperature.
Other types of heat pump include ducted heat pumps, ducted mini-splits and central air handler mini-splits. Talk to your electric utility or contractor to learn more about which type of heat pump would be best for your home.
