Process of antibacterial action in electric domestic water storage heaters and device using this process

Method is of the thermal cleaning type in which an automatic reheating cycle is activated inside the water heater for a temperature of 'n' degrees. The cycle is automatically activated after every 'x' number of days. The value 'n' can be predetermined so as to correspond with a temperature capable of reducing the most common and dangerous bacteriological load inside the water accumulation deposits, that is about 75 degrees centigrade. The anti-bacteria electronic system for the water heater has an electronic card (1) which contains a microprocessor (U1); a control relay (REL1) designed to supply an electrical resistance sanitary water heater; a potentiometer (R5) designed to adjust the temperature of the sanitary water contained in the water heater; a water temperature sensor; the card can also include; a green LED indicator (D14) designed to signal correct operation of the system; a red LED indicator (D15) designed to indicate a fault; a number of white LED's (D10) designed to indicate the level of the heater contents; a current transformer (TRF1) supplying the electronic circuits and providing current protection for the water heater; a second temperature sensor. An Independent claim is also included for the device used to reduce bacterial contamination in sanitary water heaters.
