Maximising Heat Pump Efficiency in Kiwi Winters

Modern high-wall heat pumps are the most efficient way to warm a New Zealand home, but running them incorrectly can quickly drive up your electricity costs. To get the best performance, you should always set the thermostat between 18 and 20 degrees Celsius, as every degree higher adds about 10 percent to the running costs. It is also crucial to keep the unit running on "heat" mode rather than "auto," which prevents it from accidentally switching to cooling when the room warms up. Additionally, make sure to clean the filters at least once a month so the fan doesn't have to work twice as hard to circulate air, and keep the outdoor compressor clear of winter debris like leaves or snow to maintain proper airflow.
