Heat Pumps offer maximum Energy Efficiency
EECA has identified Heat Pumps as one of the most energy efficient forms of heating available
in New Zealand. 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.
Typically, only 1kW of electrical energy is required to “pump” up to 4kW of available heat
energy from the outdoor environment to a specific area inside the home. In other words, the Heat Pump
transfers a lot more available energy then it actually consumes. With energy efficiencies of up to 400%,
this is why Heat Pumps are promoted by EECA as one of the most energy efficient forms of heating
available to New Zealanders. This is often represented as a COP or a Coefficient Of Performance.
The ratio of kW input to kW output. In the example above the COP would be 4.
So why are Heat Pumps better then any other forms of heating?
Simply put, the more energy efficient a heating system is, the cheaper it is to run.
And, the more energy efficient a heating system is,
the smaller its carbon footprint will be.
Higher Energy Efficiency = Lower Running costs
Higher Energy Efficiency = Smaller carbon footprint
Next to all common forms of heating, a Heat Pump is the most energy efficient and cheapest heating system to run with the smallest of carbon footprints.
It just makes sense!
How do Heat Pumps stack up to other forms of heating?
Heat Pumps are one of the cheapest forms of heating.
Air-conditioning systems based on Mitsubishi Electric technology achieve average COP
(Coefficient of Performance) figures of more than four.
This means that to achieve four kilowatts of heating or cooling power,
they use an average of less than one kilowatt of electricity.
A conventional heating system such as an electric or gas boiler has a COP of less than one.
This means that it burns more than one kilowatt of power to produce a kilowatt of heating power.
The higher the COP the cheaper a heating appliance is to run.
In comparison to other forms of heating, Heat Pumps offer the most energy efficient heating with
between 300% to 400% efficiency.
In dollar terms this means, a Heat Pump is one of the cheapest methods to heat a home.
