Let’s skip the generalities. You know Mitsubishi makes good heat pumps — that’s why you’re here. What matters now is which model actually fits your space, your budget, and how you live. Whether you’re heating one bedroom or the entire house, Mitsubishi has a system that’ll do the job efficiently and without becoming the noisiest thing in the room.

Below, we break down Mitsubishi’s most popular heat pump options, what they’re good at, and how to decide which one’s right for you.

 

EcoCore AP Series

If you’re after a heat pump that just works with no fuss, no noise, and no excess power use, the AP Series is a great place to start. It’s Mitsubishi’s quietest high wall unit yet, clocking in at just 18dBA at its lowest fan speed. For context, that’s quieter than your fridge.

The AP Series is well-suited to bedrooms, studies or anywhere silence matters. It’s also a solid choice for smaller living areas where space is tight, but you still want reliable heating through winter and cooling in summer.

Built with EcoCore technology, it also delivers on the energy-efficiency front. If you want something that runs quietly in the background without needing regular adjustment, this one’s worth a look.

Good for:

  • Bedrooms
  • Compact living areas
  • Quiet zones (home offices, nurseries)
  • Budget-conscious efficiency seekers

 

Designer EF Series

The Designer Series does what the name suggests. It brings together all the performance Mitsubishi is known for, and wraps it in a more considered design. Slimline, smart-looking, and available in three finishes – Pure White, Matte Silver, or Rich Black Diamond — it’s a welcome alternative to the usual bland white box.

It’s also equipped with built-in Wi-Fi, so you can manage the temperature and settings from your phone without needing a separate module or clunky add-ons. Performance-wise, it’s on par with the AP Series, but with extra visual appeal and that integrated smart control.

Good for:

  • Living rooms and open-plan spaces
  • Design-conscious homeowners
  • Smart home setups
  • Anyone who doesn’t want a standard white unit on the wall

 

Black Diamond LN Series

This one’s for people who want the best of everything — looks, brains, and brawn. The Black Diamond LN Series brings advanced features like a 3D i-See Sensor (which tracks where people are in the room and adjusts airflow accordingly) and Plasma Quad Filtration for cleaner indoor air.

You’ll also get Dual Barrier Coating to reduce dust and grime build-up, and built-in HyperCore Technology on the 2.5–5kW models, which means it’ll keep heating properly even when it’s -15°C outside.

Add in the choice of three striking colours, and this is Mitsubishi’s most advanced wall-mounted option for residential spaces.

Good for:

  • Larger living rooms
  • Homes in colder regions
  • People with allergies or pets
  • Tech-savvy homeowners looking for custom comfort

 

Rapid Heat Floor Console

Not a fan of wall-mounted units? Got a cavity left over from an old fireplace or a removed night-store heater? The Rapid Heat Floor Console might be your best bet.

Its slim profile allows it to slot into areas where a wall unit would look out of place or simply not fit. Despite the compact appearance, it still packs a decent heating punch, with rapid warm-up times and even distribution.

It’s a great option in renovations or villas where retaining original features means wall mounting isn’t ideal.

Good for:

  • Renovated homes
  • Replacing old fireplaces or heaters
  • Situations where wall space is limited

 

Mitsubishi Ducted Heat Pump Systems

If you’re building new, doing a major reno, or just want heating and cooling throughout the house with zero wall clutter, then a ducted Mitsubishi system is the top-tier choice.

You’ll get consistent temperature control across multiple rooms, with only discreet grilles visible. It’s quieter than most standalone units and comes with optional zone control, so you’re not heating empty rooms unnecessarily.

Yes, it’s a bigger upfront investment — but for whole-home comfort that feels seamless, it’s hard to beat.

Good for:

  • New builds
  • Full-home renovations
  • Multi-room control with a single system
  • Families wanting a consistent, discreet solution

 

OmniCore Multi-Room Systems

If your home has a few key spaces to heat or cool but doesn’t need full-ducted coverage, OmniCore offers a middle ground. You can connect multiple indoor units (wall-mounted, floor consoles, or cassettes) to a single outdoor unit, keeping the garden tidy and the installation more affordable.

Each room gets independent temperature control, so no one needs to argue about being too warm or too cold. Plus, with inverter technology, you’ll still get impressive energy efficiency across the whole system.

Good for:

  • Multi-bedroom homes
  • Flats with separate living areas
  • Zoned comfort with fewer outdoor units
  • Families with different heating preferences
