Why is my Panasonic WH-ADC0309H3E5 Heat Pump system hard to heat up?

Your Panasonic Heat Pump system may take longer to heat up if the panel and floor are heated simultaneously, which can decrease the warm water temperature and reduce heating ability. Also, low outdoor air temperature or a low preset water outlet temperature can extend the heating time. Check if the discharge outlet or intake inlet in the outdoor unit is blocked by obstacles like snow.
