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

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
