Questions and Answers

    Why is my Panasonic Heat Pump system hard to heat up?
    • J
      Joseph AllenAug 13, 2025
      Several factors can affect the heating performance of your Panasonic Heat Pump. If the panel and floor are heated simultaneously, the warm water temperature may decrease, reducing the system's heating ability. Low outdoor air temperature or a low preset water outlet temperature can also extend the heating time. Additionally, obstructions like snow blocking the discharge outlet or intake inlet of the outdoor unit can impede performance.

      Nina WalkerAug 16, 2025
      If your Panasonic Heat Pump starts operating with cold water, it will take some time to heat the water to the desired temperature. The system requires a period to warm up the water.

    Why is my Panasonic Heat Pump making a loud refrigerant noise?
    • M
      Matthew GrahamAug 25, 2025
      The loud refrigerant noise you hear is due to the protection control during the de-ice operation. This occurs when the outdoor ambient temperature is lower than -10 °C.

    Why is there a delay when restarting my Panasonic Heat Pump?
    • G
      Greg BoydAug 28, 2025

    • M
      Mrs. Anne Gutierrez DVMAug 31, 2025
