Single-zone versus multi-zone air-source heat pumps
Single-Zone
Single-Zone systems feature a single outdoor unit connected to a single indoor unit for distribution. The indoor unit can be either a ductless console that heats a single room, or a ducted air handler that can provide heat to multiple rooms.
Easy installation and light material costs make single-zone systems a cost effective option for heating smaller homes.
They also provide an efficient solution for conditioning additions, garages, workshops, or other spaces that are difficult to connect to your home’s main heating system.
Multi-Zone
Multi-zone systems include a single outdoor unit connected to up to eight indoor units. These units can be ducted, ductless, or any combination of both types.
Each zone provides the opportunity for personalized control to match the needs of the space, giving complete control of each zone’s setpoint and energy consumption. With this system, you can keep your workout area nice and cool, while having a warm and cozy living room. Enjoy the freedom to control your equipment from your phone or use a handless remote control for each indoor unit.
A common design for home retrofits is to utilize an air handler connected to the existing ductwork and a few ductless wall cassettes to target the most important areas (like a master bedroom) or provide comfort to rooms with inadequate air flow (bonus rooms or upstairs bedrooms). This mixed multi-zone approach brings efficiency and comfort by adapting to the home without major changes of the ductwork.
