This is a system for controlling the heating of water in the tank, water in tank adapted to be heated by a first heater and a second heater, the system comprises a timer adapted to keep time, and a sensor to monitor the temperature of the water in the tank at a first position and the temperature of the water in the tank at a second position. The system is adapted to set a first set point temperature at a specified time and the first set point temperature is varied by the system over time. The system is also being adapted to set a second set point temperature the second set point temperature also being varied by the system over time. The system has an activator to activate the first heater to maintain the temperature of water in the tank at the first position at about the first set point temperature at a specified time. The system has an activator to activate the second heater to maintain the temperature of water in the tank at the second position at about the second set temperature at a specified time.
