* The above comparison looks at the most popular 6kW heat pumps suitable for a medium sized room. These are by no means the only heat pumps that New Zealand Heat Pumps recommend. Please talk to our heat pump specialists about your specific requirements.

** COP stands for Coefficient of Performance – in other words the relationship between energy used and heat delivered – for example a COP of 4.11 produces 4.11kW of heat for every 1kW of energy used or to simplify, the higher the COP, the better!

Editor’s choice – Our recommended heat pump for this month is the Fujitsu E3; undoubtedly the most energy efficient heat pump in the 6kW class.
