No Wall Space? Meet the Heat Pump Freeing Up Your Wall Space For the Things You Love

Vicky Keatley • June 23, 2026

When most people think of a heat pump, they picture a unit mounted high on the wall. It's become the standard solution for heating and cooling Kiwi homes.

But what if you could enjoy all the comfort of a heat pump without sacrificing valuable wall space?

Introducing the Mitsubishi Electric AireTile Slim MLZ Cassette Series, the discreet ceiling-recessed heat pump designed for modern homes where comfort and interior design go hand in hand.

Why Wall Space Matters More Than Ever

Many Christchurch homes are changing. New builds are embracing open-plan living, larger windows, feature walls, built-in shelving, and flexible spaces that can adapt as families grow and lifestyles change.

The challenge? All these design features leave less available wall space for a traditional high wall heat pump.

Whether you're building a new home, renovating, or simply looking for a more discreet heating and cooling solution, the AireTile Slim offers a fresh alternative.

Comfort From Above

Unlike a traditional wall-mounted heat pump, the AireTile Slim is recessed into the ceiling, with only a slim white grille visible. The result is a clean, uncluttered look that blends seamlessly into your home's design while delivering year-round heating and cooling.

This makes it ideal for:

● Living rooms with large windows

● Bedrooms where wall space is limited

● Home offices and media rooms

● Townhouses and apartments

● Homes with feature walls, artwork or built-in cabinetry

Instead of designing around your heat pump, you can design your room exactly the way you want.

Surprisingly Slim

One of the standout features of the AireTile Slim is its compact design.

At just 185mm high, it is designed to fit into ceiling spaces where many other ceiling-mounted systems simply can't. It also fits neatly between standard New Zealand ceiling joists, making it suitable for many modern homes, townhouses and renovations.

For homeowners, this means you can enjoy the benefits of a ceiling-mounted system without needing the large ceiling cavity typically required for ducted heating.

Quiet Comfort Day and Night

Starting from just 26dBA, AireTile Slim delivers quiet heating and cooling that won’t interrupt sleep, work or relaxation. Its ceiling-recessed design also helps minimise perceived sound in the room, making it ideal for spaces where comfort should be felt, not heard.

A Great Alternative to Ducted Heating

Many homeowners love the idea of a hidden heating solution but don't always have the ceiling space or budget for a full ducted system.

The AireTile Slim bridges that gap by offering a discreet ceiling-mounted option that delivers targeted comfort to individual rooms while maintaining a clean architectural look.

It's an excellent choice for homeowners who want something more subtle than a wall-mounted heat pump, but don't necessarily need a whole-home ducted solution.
