Calculations

Time and output

Time to heat water (minutes) Volume x temperature rise / output x 14.3
(liters x °C / kW x 14,3)
kW loading required to heat water (kW) Usage x temperature rise / 858
(liters/uur x °C / 858)

Mean temperature of mixed water(°C)

Hot water / Cold water (liters) Volume hot water x Temperature hot water +
Volume cold water x Temperature cold water
Volume hot water + Volume cold water
