Why does my Hitachi Air Conditioner take so long to heat up water?
If the water from your Hitachi Air Conditioner isn't getting hot enough or takes too long to heat up, check the water temperature settings to ensure they are correct. Also, make sure that the air outlet or air inlet of the outdoor unit isn't blocked. Finally, check the unit for water leaks.

Water leakage during the heating operation of your Hitachi Air Conditioner is normal. The water in the tank expands as it heats up, discharging about 3% of the tank's volume. However, if water leaks from the outlet during operations other than heating, it indicates that the safety pressure relief valve is defective.
