FIELD: power engineering.
SUBSTANCE: invention relates to thermal power engineering and may be used in gas water heaters of any type that heat water and have expansion tanks. An expansion tank for a gas water heater may be made with low costs due to its simple design and may have high resistance to pressure and high corrosion resistance in case of heating water action. The expansion tank includes a body having an upper part and a lower part, which are open, and comprising a latticed unit for the reception of heating water, separated into compartments by means of multiple diaphragms, receiving heating water and made as a whole with multiple diaphragms; and an upper inner cover and a lower inner cover, which are connected to the body to close the upper part and the lower part of the body.
EFFECT: improved design.
