Individual room comfort. One intelligently designed system. Mitsubishi Electric OmniCore multi-room heat pump systems designed for Canterbury homes where a ducted system isn't practical.

Multi-room comfort where ducted isn't practical
Not every home is suited to a traditional whole-home ducted heat pump system.
Homes with limited ceiling space, complex roof structures, multiple storeys or areas that are difficult to reach with ductwork can still enjoy carefully designed heating and cooling across multiple rooms.
Heat Pump Upgrade Co designs Mitsubishi Electric OmniCore Multi-Room Heat Pump Systems that allow multiple indoor units to operate from a single outdoor unit — providing individual comfort where you need it without surrounding your home with multiple outdoor units.
How OmniCore works
One outdoor unit. Comfort across multiple rooms.
See how Mitsubishi Electric OmniCore Multi-Room systems connect multiple indoor units to one outdoor unit, providing individual comfort across different areas of the home without the need for a traditional ducted system.
Comfort designed room by room
Rather than one-size-fits-all
We assess the heating and cooling requirements of each area of your home and select the appropriate indoor unit, capacity and location for each space.
Your system can combine different Mitsubishi Electric indoor unit styles depending on the architecture and requirements of the home, including:
This gives us considerably more design flexibility when a conventional whole-home ducted system isn't practical.
One outdoor unit. Multiple rooms.
A cleaner exterior. Individual room comfort.
A Mitsubishi Electric OmniCore system can connect multiple indoor heat pumps to a single outdoor unit.
This creates a cleaner exterior installation while allowing bedrooms, living areas, offices and other selected rooms to have their own indoor comfort solution.
Depending on the system selected, OmniCore solutions can accommodate up to eight indoor units.

How OmniCore connects
One outdoor unit. Multiple indoor units.
A Mitsubishi Electric OmniCore system connects multiple indoor units — high walls, floor consoles, ceiling cassettes and more — to a single outdoor unit through refrigerant piping.
Each indoor unit operates independently, providing individual temperature control for different areas of the home while maintaining a clean exterior with only one outdoor unit.

Individual temperature control
Different rooms have different comfort requirements
With a multi-room system, each indoor unit can be individually controlled, allowing you to heat or cool the areas you're using rather than treating the entire home as a single zone.
Bedrooms can be set differently from living areas, unused rooms can be switched off, and comfort can be tailored around how your household actually uses the home.
Designed around your home
The performance depends on more than choosing several indoor units
A multi-room system is a complete solution — not a collection of individual heat pumps. Heat Pump Upgrade Co considers:
Every system is designed as a complete solution rather than a collection of individual heat pumps.
A premium alternative
Where ducted isn't practical
For homes with sufficient ceiling or underfloor space, a Mitsubishi Electric ducted system may still provide the most discreet whole-home solution.
Where the building doesn't allow practical ductwork, a professionally designed Mitsubishi Electric OmniCore Multi-Room system provides another way to achieve high-quality heating and cooling throughout multiple areas of the home.

Frequently Asked Questions
Common questions about multi-room heat pumps
What is a Mitsubishi Electric OmniCore multi-room heat pump system?→
An OmniCore system allows multiple Mitsubishi Electric indoor units to operate from a single outdoor unit. This provides individual room comfort without surrounding the home with multiple outdoor units. Heat Pump Upgrade Co designs the complete system around the specific requirements of each space.
How many indoor units can connect to one outdoor unit?→
Depending on the system selected, Mitsubishi Electric OmniCore solutions can accommodate up to eight indoor units. The actual number of units suitable for your home depends on the outdoor unit capacity, the rooms you want conditioned and the simultaneous heating or cooling demand.
Is a multi-room system better than a ducted system?→
Neither system is universally better. A ducted system provides the most discreet whole-home solution where ceiling space allows. A multi-room system is a premium alternative for homes where ductwork isn't practical — such as homes with limited ceiling space, complex roof structures or multiple storeys. Heat Pump Upgrade Co can advise on which approach suits your home after assessing the property.
Can each room have its own temperature?→
Yes. With a multi-room system, each indoor unit can be individually controlled. Bedrooms can be set differently from living areas, unused rooms can be switched off, and comfort can be tailored around how your household actually uses the home.
What brand of multi-room heat pump does Heat Pump Upgrade Co install?→
Mitsubishi Electric exclusively. Heat Pump Upgrade Co has chosen to specialise rather than offer numerous competing brands, so we can deliver deeper product knowledge and better long-term support.
Can different indoor unit styles be mixed in one system?→
Yes. Depending on the system selected and compatibility, your system can combine different Mitsubishi Electric indoor unit styles — such as high wall units, floor consoles, ceiling cassettes and concealed ceiling units — within the same OmniCore system. This provides considerable design flexibility for homes with varied room types and architectural requirements.
