wolflet 1 Report post Posted June 8, 2010 Anyone know what is the Joven 25L model number with new energy saving ? I do not want end up paying for less efficient model.... From Joven website, the vertical model seem to be more energy efficient as compared to horizontal model with different temp setting. Correct ? Joven Vertical model has a control knob which allows temperature setting from 'OFF' to 70°C (Low-Medium-High). Under normal operation the thermostat cuts out at the set temperature - Low (about 40°C), Medium (about 55°C), High (about 70°C). When the hot water consumption is not in large volume, setting at Medium will minimise electrical consumption. The horizontal model has a built-in thermostat which is pre-set at 70°C to provide maximum hot water, ready for immediate use. Thanks. imo, its about the same. you set temp lower, the ratio of hot vs cold is higher. thus hot water use up faster, the heater will keep trying to heat the water. at a higher temp setting, it may take longer to heat the water. but because the water lasts longer in the tank. the heater doesnt have to turn on so frequently. If its me, i would go for 70deg, let the water heat to 70, turn off the power. and shower. in this case, the heater will only be on for about 10-15 mins as the water in the tank should be more than sufficient for 2-3 persons. on the other hand, a heater set at 55deg will have to be kept on thruout the shower period of the 2-3 person. drawing more electricity in the long run.
