What is Ducted Heating?

Ducted heating is a central heating and cooling system designed to deliver conditioned air throughout your entire home via a network of hidden ducts. As with the standard high wall system, there are two main parts to a ducted system : the outdoor or condenser unit, a main typically located outside, and an indoor unit, usually hidden in the ceiling or under the floor. This indoor unit then distributes air through ductwork connected to unobtrusive vents placed in each room. The only visible components are the subtle grilles and a wall-mounted controller. This discreet design allows for powerful heating with only a subtle impact on your interior aesthetics.

Why Choose Ducted Heating for Your NZ Home?

New Zealand winters can be unpredictable, ranging from mild and damp to intensely cold. Traditional heating with fireplaces or even high wall heat pumps often creates uneven temperatures, with the heated room very warm with other parts of your home ice cold. Ducted heating directly solves this, providing a sophisticated and efficient solution for consistent warmth in every room of the house it is installed in.


Here are the key ducted heat pump benefits that make it the best solution for whole home comfort:

  1. Consistent Whole-Home Heating:

    • Comfort in every room: A primary advantage is its ability to maintain a consistent temperature across every room. This eliminates cold spots and ensures a comfortable environment throughout your entire house, from living areas to bedrooms. No more jerseys or jackets needed inside!

    • Eliminates Cold Spots: Unlike single-room heaters, ducted systems distribute warmth evenly, meaning no more sudden chills when moving between spaces. This is essential for larger homes or open-plan designs and prevents mould forming in cold, damp corners of the house..

  2. Superior Energy Efficiency:

    • Heat Transfer Technology: Ducted heat pumps operate by transferring heat from the outside air into your home, rather than generating it from scratch. This process is significantly more energy-efficient than other forms of heating.

    • Lower Running Costs: Modern ducted systems can deliver multiple units of heat energy for every unit of electrical energy consumed, leading to substantial savings on your power bills.

    • Zoning Capabilities: Many systems offer zoning (extra cost option), allowing you to heat only the specific areas you are using. This intelligent control minimises wasted energy, keeping operating costs to a minimum.

  3. Discreet and Aesthetically Pleasing:

    • Invisible System: The main components and ductwork are concealed within your home's structure. Only sleek, unobtrusive vents (which come in multiple different designs and colour), are visible.

    • Maintains Interior Design: This hidden design frees up wall and floor space, preserving your home's aesthetic and allowing for greater flexibility in furniture placement.

  4. Quiet Operation:

    • Minimal Noise: Since the main fan unit is hidden inside the ceiling or underneath the floor, ducted heat pumps operate remarkably quietly. The only sound is a gentle airflow from the vents, and .

    • Ideal for All Rooms: This quiet performance makes ducted heating perfect for bedrooms and  other areas (eg home cinemas) where noise levels are an unwanted disturbance or distraction.

  5. Improved Indoor Air Quality:

    • Constant Air Filtration: All ducted heat pump systems incorporate air filtration that traps a significant amount of airborne dust. Less dusting to do! .

    • Healthier Environment: By continuously circulating and filtering the air, ducted systems help create a healthier indoor air quality, particularly beneficial for allergy sufferers or those with respiratory sensitivities.

  6. Enhanced Convenience and Smart Control:

    • Programmable Settings: Modern systems come with user-friendly wall controllers for setting temperatures, programming schedules, and managing zones.

    • Smartphone Connectivity: Many modern ducted heating systems offer Wi-Fi connectivity (usually as an optional extra), allowing you to control and monitor your home's temperature remotely via a smartphone app. You can turn on  your system before arriving home, ensuring a warm welcome every time!

  7. Increased Property Value:

    • Premium Feature: Installing a ducted heat pump system is considered a premium feature many current and future buyers or renters will be impressed by. It enhances your home's value and appeal and ensures top dollar for rent or sale.

    • Modern Comfort: A fully integrated, efficient heating system creates a modern home, no matter if installed in a new-build or a 100-year old villa.

  8. Year-Round Climate Control (Heating and Cooling):

    • Dual Functionality: While excellent for winter heating, ducted heat pumps also provide efficient cooling during New Zealand's warmer months, ensuring home comfort no matter what the temperature may be outside.

    • Single System Solution: This dual capability means you have one comprehensive system for year-round comfort, eliminating the cost and operation hassle of   separate heating and cooling units.

Maintaining Your Ducted Heat Pump System

Regular maintenance is key to maximizing the lifespan and efficiency of your ducted heating system.


Homeowner Responsibilities:

  • Filter Cleaning: Regularly clean or replace air filters (every 6-12 months, depending on usage) to ensure good airflow and efficiency.

  • Clear Outdoor Unit: Keep the outdoor unit free of debris like leaves and twigs.


Professional Maintenance (Highly Recommended Annually ):

  • Comprehensive System Check: Technicians inspect all components, electrical connections, and refrigerant levels.

  • Ductwork Inspection and Cleaning: Professional cleaning prevents dust accumulation, ensuring optimal airflow and indoor air quality.

  • Condensate Drain Clearance: Ensures the drainage system is clear to prevent blockages.

  • Performance Optimisation: Experts calibrate your system for peak efficiency, proactively addressing any potential issues.


Regular professional servicing extends the life of your ducted heat pump, maintains its energy efficiency, and ensures consistent whole-home heating.
