  • Please note:
    Final outdoor unit selection will be affected by several different factors. The combination of rooms and their location, as well as operating use, will determine which of the proposed models you require. In many cases, an outdoor unit with a lower heating capacity may be adequate where not all indoor units are required to operate in maximum heating mode simultaneously. Or, if you are considering adding more indoor units in the future, in the interests of future-proofing, you may be best to select an outdoor unit capable of providing more capacity than you currently require.

Connectable Indoors

Connect multiple indoor units and hot water to a single outdoor unit.

This OmniCore Duo Multi Room and Hot Water System gives you the freedom to select the indoor model best suited to each and every room in your home. Multi-Split Systems like OmniCore Duo are designed to allow multiple indoor units of varying capacity and type to be connected to just one outdoor unit, enhancing exterior aesthetics by reducing the number of outdoor units required.

If more than one room requires heating and cooling, a Multi-Split system may be right for you. This system allows the indoor units chosen to reflect the specific needs of each room. For example, a whisper-quiet high wall could be selected for a bedroom, while a floor console could be used to replace a fireplace in the living room. The indoor units selected will be powered by just one outdoor unit, lowering the overall capital cost and increasing the energy efficiencies achieved.

Connectable Indoor Unit Types

Every home is different, and with so many options to choose from it is important to consider each individual room’s requirements as part of the overall OmniCore Multi Room system.

Use the following to learn more about the different indoor unit types available for air conditioning and water heating. This information can then be used to base your preferred selection of indoor units and control systems that best suit your home.

The outdoor unit is connected up to a specially designed Branch Box. This Branch Box is like the technological heart of the Mitsubishi Electric Multi Room. It intelligently draws energy from the outdoor unit and directs the flow of energy through its individual branch ports to the different connected indoor components.
Either an all-in-one Mitsubishi Electric Ecodan Packaged Water Cylinder system or Mitsubishi Electric Ecodan Hydrobox with a 3rd party Cylinder, can be connected to the Branch Box to satisfy the hot water requirements. Designed with flexibility in mind, the system allows for various configurations to suit different applications. It can include potable hot water, underfloor and radiator heating throughout the whole home.
