Problems solved by technology

During the operation of the gas wall-hung boiler, when the wall-hung boiler system is blocked or the water pump is stuck, the abnormality must be detected through over-temperature protection. Under extreme conditions, when the temperature detection of the system is too late to respond, there may be local high temperatures in the heat exchanger Vaporization in the area, such high temperature and high pressure working conditions are likely to cause dangers such as pipe bursts

Abstract

The invention discloses a gas wall-hanging stove with the function of monitoring the water flow for heating and supplying of domestic hot water. The gas wall-hanging stove comprises a heat exchanger,a heating loop, a domestic hot water supplying loop, a water pump and a main controller, wherein the heating loop and the domestic hot water supplying loop are connected with the heat exchanger, the water pump is arranged on the domestic hot water supplying loop, and the main controller is connected with the water pump. A first water flow sensor is arranged on the heating loop. A second water flowsensor is arranged on the domestic hot water supplying loop. The main controller is connected with a water flow anomaly alarming unit. The main controller is connected with the first water flow sensor and the second water flow sensor and controls the water flow anomaly alarming unit to work according to signals fed back by the first water flow sensor and the second water flow sensor. According tothe gas wall-hanging stove, the water flow for heating and supplying of the domestic hot water is known by a user more visually; and meanwhile, an alarm reminding signal can be sent when the water flow is abnormal, so that the safe problems of overtemperature overheating and the like due to pipeline blocking are solved.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a gas wall-hung boiler with flow monitoring for heating and domestic hot water. Background technique [0002] A gas wall-hung boiler is a device that can provide central heating functions and large-flow constant-temperature sanitary hot water functions. It usually includes: a heat exchanger, a heating circuit connected to the heat exchanger, a sanitary hot water circuit, and a water pump that provides water circulation power for the heating circuit and the domestic hot water circuit. During the operation of the gas wall-hung boiler, when the wall-hung boiler system is blocked or the water pump is stuck, the abnormality must be detected through over-temperature protection. Under extreme conditions, when the temperature detection of the system is too late to respond, there may be local high temperatures in the heat exchanger Area vaporization, such high temperature and high ...
