Method and system for parallel connection of multiple gas heaters

The invention discloses a method and a system for the parallel connection of multiple gas heaters. The system is characterized in that a temperature sensor signal is received through an MCU (micro control unit), and a corresponding gas heater heating system, which is mainly composed of a plurality of hot water heaters connected in parallel, is initiated according to demanded hot water quantity and temperature. The system comprises a central controller, a constant temperature water tank and a gas heater generating unit the working state of which is controlled by the central controller. Water inlet and outlet pipes are connected between the gas heater generating unit and the constant temperature water tank, the constant temperature water tank is externally connected with a water point by a water booster pump and a circulation water pipeline. The system of the invention employs a PC as an operating unit to work out special software system, has the advantages of strong expansibility, convenience in installation and maintenance, simplicity in operation and energy conservation, and can be installed both indoors and outdoors.
