System zoning allows different parts of a conditioned space to be controlled independently with their own thermostat and operating conditions. The primary benefits of system zoning are improved comfort and energy savings. There a four common ways to provide system zoning in a conditioned space: Ducted systems with zone dampers: Dampers within a duct system allow airflow to a portion the heating and cooling system to be regulated and redirected air to specific areas of the home. Each zone is controlled with its own thermostat. Multi-zone mini split heat pump systems: A single outdoor heat pump unit feeding heating and cooling to two or more indoor units that are control independently. Heat only hydronic systems: A natural gas, LP, or oil boiler, combined with an indoor distribution system that includes two or more heating zones. Heating zones can each be controlled by their own thermostat and controlled either by zone valve, or zone pumps. Distribution methods can be combined, and include hot water baseboard, hydronic unit heaters, or radiant floor heating. Heating and cooling hydronic systems: A natural gas, LP, or oil boiler, combined with two or more ducted hydronic air handlers, also typical containing refrigerant based cooling coils for summer comfort. Outdoor condenser(s) are added to provide summer cooling operation.
