Ducted heat pumps / air conditioners are split-type units which allow for centralized distribution of air from one air conditioner to several rooms simultaneously. Ducts leading from a centrally located unit, mounted in the ceiling space or under the floor, distribute air to several places. Identical air parameters can be maintained centrally, without the need to control a separate unit in each individual room. Another advantage is that the system can be controlled by a fixed circuit 7 day timer.

 

This type of unit is more suitable for installation in new homes or commercial building and is generally the most expensive option. Ducted systems have the least visual impact of any heat pump system; the only presence is the supply and return air grilles.
