FIELD: electrical equipment.
SUBSTANCE: invention relates to domestic water heater and to method of its operation. Domestic water heater comprises at least two reservoirs, each of which is treated by application of anticorrosion coating or is made of corrosion-resistant material, and each of which is intended to contain water for heating. Each reservoir contains at least one electric heating element located in the housing intended for immersion into water in the reservoir. Housing and reservoir are treated with the same anti-corrosive coating or are made from the same corrosion-resistant material. Housing is tightly connected to reservoir, and said at least one electrical heating element is surrounded by air inside housing so that water in reservoir is indirectly heated by radiation from said at least one electric heating element in housing.
EFFECT: invention makes it possible to design household flat water heater, in which noise associated with boiling water is limited, and phenomenon of scaling formation is reduced.
