What makes our Heat Pump technology superior?

Your Guarantee of Excellence

Quality you can rely on
  • All units line tested
  • Performance tested
  • 800 hour heat stress test
  • 2000 hour endurance test

This emblem is your assurance of the very best in technology and quality as it represents Mitsubishi Electric’s continuing efforts in making our heat pumps the industry standard. Every Mitsubishi Electric Heat Pump is a product of painstaking research, relentless testing, and a resolute determination to improve upon vital performance characteristics. As a result, our heat pumps have become more durable, less costly to operate, quieter, easier to install and maintain, and better able to distribute air evenly throughout any type of interior. This kind of commitment to quality enables our products to create remarkably pleasant environments that will ultimately make your life more comfortable.

The brand Mitsubishi Electric is not to be confused with the brand Mitsubishi Heavy Industries. Both brands may share the 3 red diamonds but are manufactured in completely different factories to completely different specifications.

NZ's Quietest Heat Pumps

We recognise that noise affects comfort, so we constantly work to make our heat pumps as quiet as possible. Our RapidHeat Floor Console and AP Series High Wall indoor units are New Zealand’s quietest starting from just 18dBA*, indoor sound level. Because we want you to feel the warmth, not hear it.

*18dBA MSZ-AP25 and MFZ-KW25/35/42 indoor sound level on lowest fan setting in heating mode.

NZ's Best Performance in Cold Conditions

The ability of a heat pump to work efficiently in low temperatures is not only important in areas where the temperature falls below zero degrees. Good low temperature performance is essential in all winter conditions. The technology behind this performance also allows a heat pump to perform better in areas with high humidity and at high altitude.

Why design to heat?

When it gets cold outside, a heat pump designed to cool needs to work overtime to produce heat and so its performance is reduced. A heat pump designed for cooling can disappoint when you need it most – when the temperature drops. We design for New Zealand homes, and therefore we design predominantly to heat. The result is year-round reliability and performance.

Superior heating, guaranteed

All our heat pumps are engineered for superior heating. You’ll stay snug no matter how cold it is outside and we guarantee this, even in outdoor temperatures as low as -15°C.

Intelligent defrost

All our heat pumps are fitted with intelligent defrost technology to ensure that you get the best performance out of your heat pump when it gets cold.

When the temperature drops below zero, all heat pumps have to perform a “defrost cycle” to remove ice build up on the outdoor coils. This can mean that your heat pump will temporarily stop operating or will blow out cooler air.

Mitsubishi Electric has developed an advanced version of this, using Fuzzy Logic to learn, measure and record temperatures and running times. This data is then used to ensure defrost cycles are as fast, efficient and far apart as possible – so you can get heat quicker.

HyperCore® High Performance Heat Pumps

Our HyperCore Heat Pumps are guaranteed to perform at its peak from +7°C to –15°C and will not lower their heating performance even when it is snowing outside. So you can be assured that you will be kept snug throughout winter. HyperCore is also highly recommended for humid and high altitude areas.
