Comfort That Fits into Your Ceiling

Many modern homes feature large windows, open-plan layouts, architectural lighting, built-in cabinetry and carefully considered interiors. These design features can leave limited space for a conventional high-wall heat pump.


AireTile Slim delivers heating and cooling from above, so you can maintain a clean, uncluttered room without giving up the comfort of an efficient heat pump.


At only 185mm high, its compact indoor unit is designed to fit within limited ceiling spaces and between standard New Zealand ceiling-joist spacing of 450–600mm. Suitability will depend on the construction and available space within your particular ceiling.

Why Choose an AireTile Slim Heat Pump?

Keep your walls beautifully clear

The indoor unit is recessed into the ceiling, with only its contemporary white grille visible. This makes it an excellent option for rooms with:


  • Floor-to-ceiling or extensive glazing
  • Feature walls and artwork
  • Built-in shelving or cabinetry
  • Central lighting arrangements
  • Limited usable wall space
  • Carefully planned architectural interiors
  • Quiet comfort that stays in the background


Starting from just 26dBA, AireTile Slim provides quiet heating and cooling suitable for bedrooms, living spaces and home offices. Its ceiling-recessed position helps comfort become part of the room without visually dominating it. Mitsubishi Electric


Heating and cooling from above

AireTile Slim provides familiar one-way airflow from a discreet ceiling unit. Horizontal airflow can direct conditioned air across the ceiling before it circulates gently through the room, helping to reduce uncomfortable draughts.


Airflow tailored to your room

Adjustable vanes allow airflow to be directed up or down and, when Econo Cool is operating, from left to right. Dual-level airflow selection also allows the system to be configured for standard or higher ceilings, helping deliver balanced comfort across the room.


Efficient R32 technology

The AireTile Slim uses R32 refrigerant to deliver efficient heating and cooling with a lower environmental impact than older R410A refrigerant systems.


Optional Wi-Fi Control

Add optional Mitsubishi Electric Wi-Fi Control to manage your AireTile from your compatible phone, tablet or computer.


You can pre-heat or cool your room before arriving home, adjust settings when plans change or check that the system has been turned off while you are away.

A Discreet Alternative to a Wall-Mounted or Ducted Heat Pump

AireTile Slim occupies a useful space between a conventional high-wall heat pump and a fully ducted system.


It provides targeted comfort for an individual room or living area without requiring a prominent wall-mounted indoor unit. It can also be suitable for homes where a complete ducted system is unnecessary or where ceiling-space limitations make conventional ducting difficult.


The best option will depend on your home, the rooms you want to heat and cool, your ceiling construction and the available installation routes. Our team can assess these factors and recommend the most appropriate solution.

AireTile Slim may be a good choice for:


  • Open-plan living, kitchen and dining areas
  • Living rooms with extensive glazing
  • Bedrooms with limited wall space
  • Home offices and media rooms
  • Townhouses and apartments
  • New homes and architectural builds
  • Renovations and interior upgrades

Frequently Asked Questions

  • What is an AireTile Slim heat pump?

    The Mitsubishi Electric AireTile Slim is a one-way cassette heat pump. Its indoor unit is recessed into the ceiling, with a slim white grille visible from the room. It provides both heating and cooling without occupying valuable wall space.

  • How much ceiling space does AireTile Slim require?

    The indoor unit is only 185mm high and is designed to fit within relatively tight ceiling spaces. However, additional clearance and suitable access will be required for the unit, pipework, drainage and installation. An on-site assessment is the best way to confirm suitability.

  • Can AireTile Slim be installed in an existing home?

    Potentially. It can suit some renovations and existing homes, provided there is adequate ceiling space, access and a suitable route for the necessary services. Our team can inspect your property and advise what is practical.

  • Is AireTile Slim a ducted heat pump?

    No. It is a ceiling-recessed cassette that delivers air directly into the room through its grille. It offers a more discreet appearance than a wall-mounted unit without requiring the extensive ductwork of a whole-home ducted system.

  • Is it suitable for bedrooms?

    Yes, subject to correct sizing and installation. AireTile Slim starts from 26dBA and includes adjustable airflow, making it suitable for spaces where quiet comfort is important.

  • Can it heat and cool an open-plan living area?

    Yes, the MLZ range includes models for different room requirements, including the 6.0kW heating-capacity MLZ 50. The correct model will depend on the size, layout, insulation and glazing of the space.

  • Does AireTile Slim have Wi-Fi?

    Wi-Fi Control is available as an optional upgrade. This allows compatible devices to be managed remotely through Mitsubishi Electric’s Wi-Fi Control platform.

  • How do I know which model I need?

    Heat pump selection should be based on more than floor area alone. We consider insulation, glazing, room orientation, ceiling height, layout and the way the room is used before recommending an appropriate model.
