Why is my Panasonic WH-MXF12D6E5 Heat Pump system difficult to heat up?
- P
  Patricia SanchezAug 18, 2025
  If your Panasonic Heat Pump system is difficult to heat up, especially when operating floor heating or a panel heater simultaneously, it might be because the warm water temperature is getting lower, which weakens the heat-up process. Also, low outdoor air temperatures can make it difficult to get warm. Check whether snow is blocking the discharge outlet or intake inlet of the mono bloc unit. Finally, ensure the water outlet set temperature is not too low.
