Abstract
The formation of bacteria and germs, in particular of legionella during the heating of hot water is prevented by the special cold water outlet inside the hot water heater. In this hot water heater the entire cold water consumption is directed through the hot water heater. At the same time the pressure level in the cold water system and in the hot water system is also the same, whereby the disadvantage of fluctuating mixing temperatures for the consumer is avoided, i.e. at the point of use.
Claims9
Hot water heater comprising a storage container having means through which hot and cold water flows for consumption by separately withdrawing hot and cold water from the container, a cold water inlet in the lower region of the container, a hot water outlet in the upper region of the container, a heating element arranged in the storage container, and a cold water outlet provided in the lower region of the container through which outlet cold water flows, said cold water outlet being for connection to a cold water domestic supply.
Hot water heater comprising a storage container through which hot and cold water flows for consumption by separately withdrawing hot and cold water from the container, a cold water inlet in the lower region of the container including a pipe bend for directing flow from said cold water inlet to the lower region of the container, a hot water outlet in the upper region of the container, a heating element arranged in the storage container, and a cold water outlet provided in the lower region of the container through which outlet cold water flows, said cold water outlet being for connection to a cold water domestic supply.
