A system and a method for preventing bacteria growth and proliferation, and particularly the Legionella bacteria, in a water tank of an electric water heater is described. A small pump is mounted on the water heater and has a power rating greater than the domestic water supply. The pump is controlled by a controller to pump hot water from the upper region of the tank to the lower region of the tank. The pump is connected between the hot water outlet of the tank and the cold water inlet to which an elongated dip tube is secured and with its discharge end positioned in close proximity to the bottom wall of the tank. The controller has a timer and is programmed to pump the hot water during non-peak hours of the utility for a preset time and for a preset period of time depending on such criteria as water quality, public regulations and laws.

An electric water heater is described and wherein the bottom portion of the water holding tank is provided with various forms of electric heating elements to heat the water in the lowermost region of the tank adjacent the dome-shaped bottom wall to a temperature sufficient to prevent the proliferation of bacteria growth such as the Legionella bacteria in such lowermost region. The insulating foam support base of the water heater also provides a thermal barrier to the heating elements while biasing the heating element on the dome-shaped bottom wall in a region to insure excellent heat transfer to the cavitated zone surrounding the dome-shaped bottom wall where sedimentary deposits occur to create a culture medium for bacteria growth. In one embodiment a heating wire transfers heat to the lowermost region from the lower end of the surrounding side wall of the tank and access to the heating wire is provided for connection and removal thereof.

A water heating and treatment system with UV lamp and anti-scale water treatment sanitation for suppression of pathogens and undesired bacterial content in a domestic hot water system includes an anti-scale device, and a UV sanitation lamp. A single or multiple mixing station supplies heated water to one or multiple temperature zones. A water heater sanitation loop includes a sanitation loop pump to circulate hot water within the water heater. A three-way return water diverter valve allows for safe sanitation of a domestic hot water system by diverting over temperature re-circulated water away from the mixing valve to a drain, as needed. A method for treating hot water to suppress pathogens and undesired bacterial content in a domestic hot water system is also described.

The invention provides for protection of life safety, property and the liability thereof, by means of a intrinsically safe unpressurized storage tank water heater while producing hot pressurized water. The design addresses, with effect, convection, radiation, conduction and evaporative heat energy losses. Heat lost returned as usable hot water resulting in ultra-low standing loss. The stationary water medium prevents sedimentation, fouling of the heating element and gases expelled. Being dielectrically isolated, the medium may also be treated to further reduce corrosion. The design allows for a quick recovery rate and provides adjustable volume of hot water, being stackable, stage able, renewable, repairable and recyclable.

A tempered hot water delivery system configured to prevent or reduce colonisation of Legionella bacteria in tempered water delivered from the system to one or more outlets in a facility. The system comprises: a thermostatic mixing valve comprising; a hot water inlet for connection to a supply of hot water at a temperature of at least 60 C., a cold water inlet for connection to a supply of cold water, a tempered water outlet for supplying tempered water obtained from mixing the supplied hot water and cold water to provide tempered water at a temperature of between 36 C. to about 53 C. to at least one tempered water outlet of a facility, a recirculating inlet for connection to a recirculating water line circuit; and a recirculating water line circuit comprising a circulating return line connected to a circulating return outlet from the facility and to a water inlet feed line for connection to an inlet of a water heater and storage tank for providing the supply of hot water, the recirculating water line circuit further comprising a thermostatic element configured to introduce hot water to the recirculating water line circuit to maintain the temperature of water in the recirculating water line circuit during periods of little or no draw-off.
