Central Heating (Ducted Heat Pump)

A ducted heat pump is a system that uses air ducts in your roof space or underfloor to discreetly deliver heating or cooling to multiple rooms at the same time.


A ducted heat pump uses ductwork to effectively deliver heating or cooling to multiple rooms in your home at the same time, ensuring drier and cleaner air flow all year round. Here at Sustainability Trust, our team installs modern ducted heat pumps that quietly distribute comfortable temperatures throughout your entire house—making them the ultimate temperature control solution. As experienced central heating installers, we take care of the full ducted heat pump installation, from helping you choose the right system from a variety of brands to getting everything installed and running smoothly. A heat pump with ductwork means no bulky wall units in every room—just consistent warmth from the lounge to the bedrooms (and no more arguments over who gets to sit under the heat pump or in front of the heater).

  • Ducted heat pumps are an increasingly popular choice amongst homeowners for complete, highly efficient indoor climate control.

    Using the same inverter technology that made singular heat pumps popular, ducted systems give the option of even greater control, across your home.

    With discreet ceiling or underfloor vents, these systems can be installed with minimal visual disruption.

    Just like a heat pump, ducted systems heat, cool and dehumidify. They can also be installed with zone control, wifi control and optional touchscreen panels.

  • The ducted heat pump systems are the ultimate choice when you want to heat your whole home without visible air conditioning units attached to your walls or sitting on the floor.

    The systems can keep you warm in winter and cool in summer.

    They will help you to keep your home healthy and limit your environmental impact.

    They are high efficiency, which means they have a low running cost compared to traditional heating methods.

  • Ducted heat pumps use the same inverter technology that traditional heat pumps use, meaning considerably lower running costs for energy input.

    The supplied air is distributed balanced and evenly throughout the home, where it makes its way back to a central return grille, generally in a hall or service area.

    From here the air is returned to the system, filtered and topped up with additional heat (or less if cooling) before being redistributed through the home. Optional fresh air intakes can also be added to systems.

  • They’re smart! The human sensor control detects the movement of people and delivers optimum efficiency and temperature control.

    The group control allows several indoor units to be controlled as a group from one wired remote control, a great option for businesses.

    A timer can be pre-set to start and stop at any time within a 24-hour period. Even better, you can set a weekly schedule and create ‘set-and-forget’ seasonal heating or cooling.

    With a night set mode, you can keep your home temperature consistent during the night and improve economy.

    With the temperature limit operations, you can also pre-define the temperature range for cooling or heating, to reduce your energy consumption.

    The Home leave function is ideal for cold climates, when activated, Home leave turns your heat pump on automatically when room temperatures drop below 10°C, keeping your home healthy at, or above, 10°C.

    Ducted heat pumps can also provide: night quiet modes, dry modes, intelligent defrost systems, hot starts, quick cool/heat modes, anti-corrosion coating, self-diagnostics with digital display and numerous other options.
