Mitsubishi Electric’s Heat Pumps are Hot Stuff

Hooray for heat pumps! Unfortunately, not every home in New Zealand is warm and dry. But when combined with proper insulation, heat pumps have an important role to play ensuring all our homes are healthy, snug and warm.

When used properly, heat pumps are one of the most economical methods of home heating. And their controllability makes them one of the easiest and cleanest methods, too. Plus, they come with the added bonus of delivering cooling aircon in the summer months.

Of course, before purchasing a heat pump, it pays to speak to a heat pump specialist. They’ll be able to advise you on the correct size unit for your home and the best location for its installation. But when it comes to which brand of heat pump provides the best overall consumer satisfaction, just ask Canstar Blue.

As part of our mission to inform consumers of the best NZ has to offer, Canstar Blue canvassed the opinions of 495 New Zealanders who had purchased and used a domestic heat pump in the past two years, across a range of categories, to measure and track their satisfaction.

To decide which heat pump offers the best level of customer satisfaction, each was rated across the following categories:

  • Ease of Use
  • Functionality
  • Quietness
  • Reliability
  • Value for Money

Coming out on top is Mitsubishi. This year’s win is the seventh accolade for the heat pump manufacturer over the past ten years, which is a remarkable achievement.

The accolade is an even more outstanding feat for Mitsubishi, as it scored a maximum of 5 Stars in every driver of satisfaction, leading to an overall 5 Star Satisfaction Rating.

Scoring 4 Star ratings, Daikin and Fujitsu also rated highly, both scoring 5 Stars for Reliability and Value for Money.

What Do We Want From Our Heat Pumps?

The answer to the above question is clear. Nearly half (40%) of respondents cite reliability as the key driver of satisfaction with their heat pumps. Quietness (17%) and Value for Money (16%) are less important factors. Overall, the main drivers of satisfaction:

Drivers of satisfaction %
Reliability 40%
Quietness 17%
Value for Money 16%
Ease of Use 15%
Functionality 12%

Keeping in the Warmth

While 50% of those in our survey affirm that a heat pump is a must in any home they live in – and 42% specifically purchased an energy efficient heat pump – it still seems there’s a lot of wasted, paid-for heat escaping from Kiwi homes.

The overall responses we received concerning insulation levels in Kiwi homes show some big gaps … and not just under doors!

Only 36% of respondents say they have insulation in their homes. Of those people:

Location of insulation %
Roof cavity 38%
Under-floor 26%
Walls 24%
Double glazing 16%

However, regardless of the level of insulation in your home, heat pumps are one of the best and economical ways to heat (or cool) your home.

And if you’re searching for the best of the best, look no further than Mitsubishi. For with seven titles under its belt, and a clean sweep of 5 Star Satisfaction Ratings in this year’s award, Mitsubishi has proven than when it comes to heat pumps, it’s hot stuff!

Types of heat pump

Air source heat pumps are by far the most common type of residential unit in New Zealand, there are three main models:

  • Split heat pumps have two main components – one inside and one outside of your home. The indoor unit is usually mounted on the wall or ceiling. Without going too deeply into the science, the outside unit absorbs heat using coils and refrigerant. This heat passes inside through pipes, where the heat is released. Reverse cycle pumps use the same method for cooling, just the other way around.
  • Multi-split heat pumps are the same as split heat pumps but with a larger single outdoor unit serving multiple indoor units. This enables one system to provide heating and cooling across multiple rooms, or even an entire house.
  • Ducted heat pump systems provide heating and cooling to an entire home without the need for noticeable indoor units. A ducted system includes a large outdoor unit and flexible ducting that runs through your floor and/or ceiling to provide heating and cooling through vents in your home. Ducted heat pumps are generally more expensive than the other types mentioned.

When purchasing any appliance, thorough research is always a good idea. Key things to consider before committing to buying a heat pump include:

  • The size and output of your heat pump is important, and will depend on the size of your home and its location. Heat pumps are measured by their output and range from approx 7kW up to 25kW. It’s critical to get professional advice when choosing the size of your heat pump. An undersized unit may struggle to heat/cool your room, consume more electricity and prove uneconomical to run.
  • Energy efficiency.  Heat pumps are usually more efficient than most heating/cooling appliances, but their efficiency varies between models. The Energywise running cost calculator is a great tool for calculating how much it could cost to heat your home.
  • Air filtration is an important consideration, especially if someone in your family suffers from asthma, other breathing difficulties or allergies. Some heat pumps contain an inbuilt air filtration system designed to improve air quality.

Canstar Blue surveyed 2,650 New Zealand consumers across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers who have purchased and used a domestic heat pump in the last two years.  In this case, 499 New Zealanders.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
