Heat Pump Systems

Heat Pump Systems

There are different types of heat pump systems to choose from. Which one is right for you depends on the size of the room or  house you want to heat or cool. The location of you home and specific needs you have.

 
Overview: Single Split (single room) Heat Pump Systems

A split system has an exterior compressor unit connected to an interior unit by copper pipes in a loop containing a refrigerant gas.

The interior unit is made up of an electronically controlled fan circulating air over a finned radiator that has the refrigerant running through it. The unit either cools or heats the air depending on the direction of the cycle.  

Advantages

Single Split Heat Pump Systems are 

  • Cost effective
  • Highly energy efficient 
Model Options
Single Split Heat Pump Systems come in a number of model options to suit different room requirements: high wall, floor consoles, ceiling cassettes, ceiling wall and concealed units
Brand Options

Single Split Heat Pump Systems are available from; 

  • Mitsubishi Electric Heat Pumps
  • Panasonic Heat Pumps
  • Daikin Heat Pumps
  • Fujitsu Heat Pumps
  • Toshiba Heat Pumps
  • LG Heat Pumps
  • Hitachi Heat Pumps
  • MHI Heat Pumps
  • Gree Heat Pumps
  • Temperzone Heat Pumps   
Design
 Single Split Heat Pump Systems design is important to ensure right air flow  
Installation
Professional heat pump installation is critical to ensure energy efficient operation and longevity of the units 
 
 
 
 
 
 
 

 
Overview: Multi-Split (multiple room systems) Heat Pump System

Multi-Split systems are designed to allow several indoor units to be connected to a single outdoor unit. This allows the best model type to be selected for each and every room.

The Multi-Split system maintains exterior aesthetics by reducing the number of outdoor units required, and also provides the ability to economically add indoor units at a later date.

The capacity of the outdoor system depends on combined capacity of the connected indoor units. Manufacturers have different system configurations and capacities  

Advantages

Multi-Split Heat Pump system work in the same way as single split systems but are more advanced allowing multiple indoor units to be connected to a single outdoor condensing unit thereby giving :

  • Reduced external installation space
  • Flexible installation options
  • Up-gradable. Plan for additional units later.   
Model Options
 The indoor units can be a mix of different model types; high wall, floor consoles, ceiling cassettes, concealed etc. 
Brand Options

Multi Split Heat Pump systems are available in a wide variety of sizes and capacities from the following manufactures in NZ.

  • Mitsubishi Electric Heat Pumps
  • Panasonic Heat Pumps
  • Daikin Heat Pumps
  • Fujitsu Heat Pumps
  • Toshiba Heat Pumps
  • LG Heat Pumps
  • Hitachi Heat Pumps
  • MHI Heat Pumps
  • Gree Heat Pumps
  • Temperzone Heat Pumps 
Design
Good design of a multi split system is essential to ensure correct sizing and positioning, hence performance, of all units plus an unobtrusive and discrete installation of all pipework.
Installation
 As with all heat pump systems the installation is critical to ensure energy efficient operation and longevity of the units 
 
 
 
 
 
 
 
 


 


Overview:  Ducted (whole house) Heat Pump Systems

A large heat pump (air handler) is mounted in the ceiling space (or sometimes under the house) and connected to the exterior compressor unit by a refrigerant loop. The indoor unit heats or cools the air, and distributes it with a fan through insulated tubes into each room via vents in the ceiling or floor.

Ducted systems are excellent for whole house heating but need to be designed carefully to take into account correct capacity sizing and the principles of air flow and temperature control.  

Advantages
  • Whole house solution
  • Unobtrusive  
Model Options
Ducted Heat Pump Systems have vents and grills as their visible elements. There are variouse design options available
Brand Options

 Ducted Heat Pump Systems are available from the following manufacturers. Each has their own range of sizes and specification. 

  • Mitsubishi Electric Heat Pumps
  • Panasonic Heat Pumps
  • Daikin Heat Pumps
  • Fujitsu Heat Pumps
  • Toshiba Heat Pumps
  • Hitachi Heat Pumps
  • MHI Heat Pumps
  • Temperzone Heat Pumps 
Design
Ducted systems are excellent for whole house heating but need to be designed carefully to take into account correct capacity sizing and the principles of air flow and temperature control.   
Installation
Ducted Heat Pump Systems work on the same principle as Single and Multi Split systems therefore will not work correctly if not installed professionally. However being a whole house solution installation errors will be quickly noticeable.
