The water flowing sound you hear during the operation of your Panasonic Heat Pump is due to the refrigerant flow inside the unit.
Why can't my Panasonic Heat Pump get warm instantly?
If your Panasonic Heat Pump system cannot get warm instantly, it may be because heatpump systems need some time to heat up the water if the unit is operated from a cold start.
Why is my Panasonic Heat Pump system difficult to heat up?
If your Panasonic Heat Pump system is difficult to heat up, consider the following potential causes: * When heating is operated by the indoor unit together with floor heating or a panel heater simultaneously, the warm water temperature may decrease, weakening the heat-up of the floor heating or panel heater. * Low outdoor air temperature can make it difficult to get warm. * Snow pile blocking the discharge outlet or intake inlet of the outdoor unit. * Low water outlet set temperature.
