FIELD: heating.
SUBSTANCE: flat water heater and method of water heating temperature control in flat water heater with two or more intercommunicating storage tanks. In the water heater cold water is supplied from water supply system to one upstream tank and then to one or several downstream tanks. Heating temperature is provided using temperature regulators which maintain it by means of switching heating devices on/off. Maximum consumption of water volume per one withdrawal from flat water heater is provided. Temperature regulators allow maintaining water temperature in downstream tank(s) not exceeding specified storage temperature, and higher temperature in upstream tank equal to specified storage temperature increased by specified overheating temperature and complying with safety standards.
EFFECT: additional reducing of water volume containing in flat water heater as compared to volume of equivalent standard water heater.
