Why is my Panasonic Heat Pump system hard to heat up?
Your Panasonic Heat Pump system may be taking longer to heat up because the panel and floor are being heated simultaneously, which can lower the water temperature and reduce heating ability. Also, low outdoor air temperatures, blockages in the discharge or intake of the mono bloc unit (like snow), or a low preset water outlet temperature can cause this issue.
