Abstract
The invention relates to a water heater comprising a cold water inlet, a hot water outlet, a fluid pathway arranged between the cold water inlet and the hot water outlet, one or more heating elements that heat water in the fluid pathway, a power electronics unit coupled to the one or more heating elements, a controller configured to regulate a temperature of the water in the fluid pathway to an adjustable hot water temperature by controlling the power electronics unit, a flow sensor to detect a water flow through the fluid pathway, and an inlet water temperature sensor adapted to determine an inlet temperature of the water. The controller determines the power that is less than the maximum power that needs to be applied to the one or more heating elements and control the power electronics unit to modulate the power applied to the one or more heating elements so that the power is equally distributed across the one or more heating elements and whereby during any fixed period of time each of the heating elements is turned on for an equal amount of time.
