Water Heater Control System

Abstract

A heating system that dispenses water to household plumbing without violating laws of Shabbat. The system includes a holding tank of water that is automatically received heated water and given intervals and it is unresponsive to actual water use. Moreover, the system ensures that any water throughout the system does not exceed a predetermined temperature that is within the bounds of the laws of Shabbat.

What is claimed is: 
     
         1 . A water control system, comprising:
 a water holding tank;   a water heater;   a first pipe comprising a first pipe distance disposed in fluid communication between the water holding tank and the water heater;   a second pipe comprising a second pipe distance disposed in fluid communication between the water heater and the water holding tank;   the first pipe distance being greater than the second pipe distance;   a water pump disposed in fluid communication with the second pipe configured to pump water from the second pipe into the water heater, and to push water from the water heater to the holding tank;   a control unit configured to run a Shabbat routine wherein, at repeated intervals, the water pump is activated for a predetermined period of time and then deactivated; and   whereby the Shabbat routine is runs from approximately sunset on Friday to until a period of approximately 40 minutes after sunset on Saturday night.   
     
     
         2 . The water control system of  claim 1  wherein the water heater is a tankless water heater. 
     
     
         3 . The water control system of  claim 1  whereby the water heater is set to a predetermined temperature. 
     
     
         4 . The water control system of  claim 3 , whereby the predetermined temperature is a temperature between 115° F. and 120° F. 
     
     
         5 . The water control system of  claim 4 , whereby the predetermined temperature is 119° F. 
     
     
         6 . The water control system of  claim 4 , whereby the predetermined temperature is 118° F. 
     
     
         7 . The water control system of  claim 4 , whereby the predetermined temperature is 117° F. 
     
     
         8 . The water control system of  claim 4 , whereby the predetermined temperature is 116° F. 
     
     
         9 . The water control system of  claim 4 , whereby the predetermined temperature is 115° F. 
     
     
         10 . The water control system of  claim 4 , whereby the second pipe length is approximately 100 feet. 
     
     
         11 . The water control system of  claim 1 , whereby the predetermined period of time during which the pump is activated is substantially equal to the period of time required to substantially pump any water contained in the second pipe into the water heater.
