Problems concerning volume of hot water
• When using hot water, the volume discharged may decrease when hot
water is used somewhere else. Also depending on the pressure of the
water line and the piping conditions, the volume of hot water discharged
may drastically decrease or even stop. In this, the volume of hot water
discharged will become stable again after waiting some time.
• There are some types of hot water taps that discharges large
volumes of hot water at first but stabilizes after time.
• In order to stabilize the temperature of hot water, the unit controls
the volume of hot water by discharging little at first and discharging
fully when the temperature becomes stable.
