Mitsubishi Electric, keeping Kiwis comfortable

Adding another Canstar Blue Award to its cabinet, Mitsubishi Electric have once again taken the Customer Satisfaction Award for 2019, following wins in 2013, 2014, 2017 and 2018. Mitsubishi has scored a perfect 5-stars in overall satisfaction, quietness while operating, reliability and ease of use, and a solid 4-stars in functionality and value for money.

In late 2017, the Government enabled the Healthy Homes Guarantee Act 2017 which meant landlords legally have to have a fixed heating device in the living room, able to heat the room to at least 18°C. And, Canstar Blue can tell you that according to more than half (52%) of the people we asked, a heat pump was considered a must in their home. It’s no wonder, with 17% reporting improvements in their health, 60% saying it was cheaper than running individual electric heaters and 23% saying it helped to reduce their power bills.

So, are heat pumps efficient?

A lot of the more traditional methods of heating our homes such as wood burners and open fires may look nice but can be inefficient as a lot of the heat is lost up the chimney.  In addition, they can be difficult to clean and surprisingly expensive to run. Another disadvantage is that while there aren’t many feelings better than huddling around the fire on a cold winter’s night, they’re not so great in the thick of summer when we’re overheating and looking for respite from the summer heat.  That’s when a heat pump steps up to cool you down.

Using a heat pump – for heating up or cooling down – shouldn’t break the bank because the running costs are relatively low, especially if you go for an energy efficient model.  As we said earlier, a number of the people we spoke to said they thought having a heat pump was cheaper than running individual electric heaters and some even said they noticed a reduction in the power bills.  But, just as they did, you will also need to fork out for the initial costs involved in buying and having your heat pump unit installed. Even a basic model will run to a few thousand dollars so it pays to do your research and even get a professional to advise what size and type of heat pump is best for your home. You should also consider what insulation you have in your home, because it’s no good spending more money trying to keep your home warm if you’re going to let it escape through cracks in doors, single pane windows or up and out of the roof.  The more typical (but usually quite pricey) things people do to insulate include installing roof, wall and floor insulation, as well as double glazing. However, keeping the chills out does not always have to be expensive. Of the 41% who say they take extra steps to warm their home, 81% put curtains up at windows to help keep the warmth in and another 60% said they put rugs on the floor or have carpet to trap the heat.

Heat pumps – what to consider

As with any appliance, researching before you buy is always a good idea (but we can see you’re already one of the 46% of people who told us they do that!).  So, key things you want to consider before you commit to buying a heat pump include:

  • The size and output of your heat pump is important and what you need will be dependent on the size of your home and where you live.  Heat pumps are usually measured by their output and generally range from 7kW up to 25kW. Getting professional advice on choosing the size of your heat pump is critical because an undersized unit will need to work a lot harder, using more electricity and may still struggle to heat or cool the room.
  • Energy efficiency is another thing to look out for.  Heat pumps are usually more efficient than most heating and cooling appliances, but they definitely vary across models.  A great tool for calculating how much it could cost to heat your home on an annual basis is the Energywise running cost calculator.
  • Air filtration is another important one especially if you or someone in your family suffers from asthma, other breathing difficulties or allergies.  Some heat pumps come with an inbuilt air filtration system designed to improve air quality, so if this is important for you, look out for the blue butterfly logo – a sign that the pump has been approved by the Asthma Foundation NZ Sensitive Choice Program.  17% of people we talked to believe their health has improved since installing a heat pump.

What is the key to heat pump satisfaction?

Unsurprisingly, functionality was the first on the list. There’s no point installing a heat pump to find it really doesn’t heat efficiently. Panasonic scored 5-stars in this category, with Mitsubishi Electric scoring 4-stars and Daikin and Fujitsu General scoring 3-stars.

Next was value for money, for which Panasonic was rated 5-stars, Mitsubishi Electric scored 4-stars and Daikin and Fujitsu General came in with 3-stars.

The third biggest driver of overall satisfaction was quietness – you want to feel the temperature change but not hear it!  Mitsubishi Electric came out on top as the only brand to receive 5-stars. Daikin was rated 4-stars, and Panasonic and Fujitsu General were rated 3-stars.

Reliability was the next driver. No one likes it when things stop working.  Luckily, with heat pumps there are few moving parts making them pretty easy to maintain and meaning they typically last a long time.  Mitsubishi Electric scored 5-stars in this category, with Daikin and Panasonic bringing in 4-stars and Fujitsu General receiving 3-stars.

Ease of use (of the controls and buttons) was also fairly important for the people we talked to. Again, Mitsubishi Electric scored 5-stars, alongside Panasonic and Fujitsu, while Daikin received 4-stars.

Types of heat pump

Air source heat pumps are by far the most common type of residential unit in New Zealand, but geothermal and absorption heat pumps are also available for more niche climates and purposes.

Sticking with air source heat pumps, there are three main models:

  • Split heat pumps have two main components – one inside and one outside of your home.  The indoor unit can be mounted just about anywhere, be it wall, floor or ceiling. Without going too deeply in to 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 basically the same as the split heat pump 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 your 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.  As you might be able to guess, ducted heat pumps are generally more expensive than the other types mentioned.

Whatever type of heat pump you’re looking for, we hope you find this review helpful.

Frequently asked questions

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.
