How do split system heaters work?

Split system heaters have two parts – one part inside and one outside.  The indoor unit blows the warm air and the outside unit contains the compressors and condensor coils.

When you switch on your split system to heat, the unit draws in ambient air and heats it before pumping it back in the room. As a result the temperature is increased as the warm air blows into the room. This cycle continues until the set temperature is reached and the system automatically shuts off.
