How often should the heat pump run?

The compressor fan starts heating water when the water temperature falls below 45 degrees Celsius, or it needs to be refilled after using hot water. It is common for this to happen 4 – 5 times during the day, and several times during the night. During the warmer months you may notice it run more often.

If the unit operating at night becomes an inconvenience, you can program it to run on a timer so it stays off while you’re sleeping. Refer to the user manual for how to do this if your unit supports that functionality.

If the unit is running all the time then you should contact the installer to have it looked at. If this occurs during your warranty period the inspection and any repairs will be covered.
