What Are Multi-Room Heat Pumps?
Professional installation of multi-room heat pump systems throughout Papatoetoe and South Auckland. Heat 2-5 rooms from one outdoor unit with independent temperature control in each space.
Multi-room systems connect one outdoor unit to multiple indoor units (typically 2-5) throughout your home. Each room gets its own temperature control and can operate independently – bedroom at 18°C while lounge runs at 22°C.
Two main system types available:
- Multi-split systems: Individual wall-mounted units in each room with separate remote controls. Most common choice for existing homes.
- Ducted systems: Central unit distributing air through ceiling or floor vents. Best for new builds or major renovations. View ducted whole-home options.
What’s Included in Installation
All our multi-room installations include:
- Outdoor unit (sized for total capacity needed)
- Indoor units for each room (2-5 units typical)
- Refrigerant piping to all indoor units
- Electrical connections and dedicated circuits
- Condensate drainage for all units
- Individual remote controls (or WiFi system)
- Full system commissioning and demonstration
- 5-year installation warranty
- Manufacturer warranties on all equipment
Pricing and System Sizing
Multi-room system costs vary based on number of rooms, total capacity required, and installation complexity.
Typical pricing for Papatoetoe homes:
- 2-room system: $6,000-$9,000
- 3-room system: $8,000-$12,000
- 4-room system: $10,000-$15,000
- 5-room system: $12,000-$18,000
Pricing depends on room sizes, unit types selected, and site-specific installation requirements.
Cost Comparison vs. Single Units
Installing separate single room heat pumps in 3-4 rooms costs more upfront and significantly more to run. Multi-room systems share one outdoor unit and refrigerant circuit, reducing purchase and running costs.
Running cost savings: 40-60% lower than multiple electric heaters. The system adjusts output based on actual demand – heating only occupied rooms reduces energy waste.
Government Subsidies
Eligible homeowners can receive up to $2,500 through Warmer Kiwi Homes programme. As an EECA-approved provider, we handle applications and paperwork. Check subsidy eligibility and details.
System Configuration Options
Multi-split advantages:
- Each room has visible wall unit with individual control
- Mix different unit types – high wall, ceiling cassette, floor mounted
- Easier retrofit into existing homes
- If one indoor unit fails, others continue operating
- Can disable unused rooms to save energy
Ducted advantages:
- No visible indoor units
- Even temperature distribution
- Integrated ventilation options available
- Better for open-plan layouts
Most Papatoetoe homes suit multi-split configuration for retrofit flexibility and independent room control.

Sizing Considerations
Outdoor unit capacity must match combined indoor unit requirements plus 10-20% overhead. Undersizing causes poor performance and shortened equipment life.
Room-by-room assessment considers:
- Individual room volumes and insulation
- Window area and orientation
- Typical occupancy patterns
- Desired temperature ranges
Use our sizing calculator for initial estimates, or contact us for detailed heat load calculations.
Installation Process
Most multi-room installations complete in 1-2 days depending on system complexity and number of indoor units.
Installation includes:
- Site survey and final positioning confirmation
- Outdoor unit installation with proper drainage and clearances
- Refrigerant piping runs to each indoor unit location

Maintenance Requirements
Annual professional servicing maintains efficiency and prevents premature failures. Multi-room systems require servicing on all indoor units plus the outdoor unit.
Included in annual service:
- Filter cleaning on all indoor units
- Coil cleaning (indoor and outdoor)
- Refrigerant pressure checks
- Electrical connection inspections
- Condensate drainage verification
- Performance testing all zones
Monthly filter checks recommended for optimal air quality and efficiency. We demonstrate filter maintenance during installation.
