Abstract
A programmable water heater thermostat controller that attaches over the temperature control unit of existing gas or electric water heaters. The user programs the temperature of water required at different times of the day. A microcontroller then compares the current temperature setting against desired setting every minute and rotates the temperature control knob accordingly using an electric motor. If vacation mode is chosen, then the microcontroller skips program times and keeps the temperature control knob at the lowest temperature setting.
Description
INVENTION TITLE
Programmable water heater thermostat controller Priority Claim This patent application claims priority from provisional U.S. patent application entitled "Programmable water heater thermostat controller", having an application number 61/241,480 filed on September 11, 2009, which was subsequently converted to non-provisional U.S. patent application with the same title, having an application number 12/877156 filed on September 08, 2010, the contents of which are incorporated herein by reference.
FIELD OF INVENTION
The present invention relates to controlling the thermostat on both electric and gas powered water heaters based on user programmed settings.
BACKGROUND OF INVENTION
Water heaters come with a thermostat to adjust the temperature of water. When the set temperature is reached, the burner in gas powered water heater or the electric coil in electric water heater is turned off. When the temperature drops below the set temperature, the water heater is turned on again. This process repeats all the time. The user sets the temperature high enough to get hot water during periods of peak usage even on the coldest day of the year. This temperature is maintained during the day as well as night when there is not much need for hot water. People seldom change the setting of the thermostat. Hence the high temperature is maintained even during summer. This results in wastage of fuel.
This also shortens the life of the water heater. There is a need for a programmable
