At Mitsubishi Electric we take energy efficiency very seriously. So with an impressive 34 models, that have been awarded the Energy Star® mark you can conclude a number of things.
Developing superior energy efficient heat pumps is part of our DNA and this is achieved through our commitment to continual advancements in technology.
When we make big claims like this, they are not single statements that are not backed up with clear, transparent facts. Firstly, we only include current models that are in stock and we actively sell. We clearly identify all of our Energy Star® models in all our brochures and on our website – allowing consumers the ability to easily distinguish which models have been awarded the Energy Star® mark. This also extends to the recommended heat pumps provided by our heat pump selector tool.
From our line-up of 24 Energy Star® awarded High Wall Heat Pumps – 6 are available in a range of colours and 3 are offered with HyperCore® Technology guaranteeing maximum heat output even right down to -15 degrees.
We have 4 Energy Star® awarded Floor Console options that are recessable for an even slimmer profile, one of which is also offered with HyperCore® Technology.
And last but not least, we also have 6 total home ducted solutions proudly wearing the Energy Star® mark. Hidden from view with only a subtle grilles visable, these Ducted Heat Pump systems are a perfect total home comfort solution.
All in all, there are 34 models in our line up ranging from 2.5kW right up to 13.5kW – meaning there is a style and capacity to suit.
It’s no accident that Mitsubishi Electric is able to present such an extensive range of heat pumps that all qualify for the Energy Star® award.
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.
Government agency EECA (Energy Efficiency Conservation Authority) has identified heat pumps as one of the most energy efficient forms of heating available in New Zealand. This is because heat pumps do not create heat; they simply move available heat from one place to another. The little electrical energy that is needed is predominantly used to run the compressor.
In fact heat pumps are so efficient that typically, 1kW of electrical energy you put in, your heat pump will produce around 4kW of heat energy out. This efficiency is represented as a COP (Coefficient of Performance), a good heat pump, operated correctly will have a COP of around 4.
Compare this to:
Electric bar heater - COP of 1
Gas heating – typical COP of 0.85
Wood fire – typical COP of 0.65
When looking specifically at electrical appliances, Energy Rating Labels and the Energy Star® mark are good indicators of how well an appliance performs.
The Energy Star® mark is the highest award for efficiency for a product in its category. So it is always a good indication that a product is in the top of its category. Energy Star® is awarded to the most efficient models on the market rated at 7°C in each size range.
Choosing an Energy Star® heat pump could save you $150 a year on running costs, compared to a non-qualified model.
In order to achieve the Energy Star, a heat pump must be able to perform efficiently at 2°C, this is called H2 testing condition (previously H1, tested at 7°C). This data is submitted to EECA, with supporting evidence. You can find this data at www.eeca.govt.nz.
