Water heating = 30-40% of restaurant electricity

Water Heating
Restaurant consumes 8 times more energy per square foot than average
building
About a third is channeled to heating water
Older heating elements heat slower, more expensive
7
A typical 3000W electric geyser element requires 5hrs to heat water from ambient temperature to 65 degrees every day
Daily energy consumption:3 000W x 5H =15 000WH per day
15kWH x 30 days = 450kWH pm

Cost of Hot Water
Minimum cost per 3 000W element for every 200L
100 000 electric geysers Potential to gobble 300MW of
generated power
Contribution to daily power cuts
A National Problem
Energy from dirty coal power plants
