Gas water heater descaling device and descaling method thereof

Abstract

The invention relates to a gas water heater descaling device and a descaling method thereof. The gas water heater descaling device is characterized in that the chemical reaction principle is utilized, a descaling agent is added into a water tank of the gas water heater, the water temperature is raised and maintained to certain temperature through heating, a water pump is started to enable the water in the water tank to circulate, the descaling agent and the main components of the accumulated scale generate chemical reaction, then the firm accumulated dirt is loosened or dissolved, and the accumulated scale is cleaned. The gas water heater descaling device has the advantages that the descaling agent can react with the water scale in the circulating flowing process, the descaling efficiency is higher, the descaling time can be freely controlled, and the accumulated scale is more thoroughly cleaned at higher temperature; after the descaling agent is added, the concentration is controlled to be stable, the descaling agent is freely added to guarantee the proper concentration, and the reaction of the accumulated scale is favorably realized; the bulky water scale is fully dissolved, the cleaning effect is good, the heating surface is clean, the good heat transfer effect is realized, and the gas consumption is saved; the structure is simple, the convenience in use is realized, the safety and reliability are realized, the descaling efficiency is high, and the usage amount of descaling amount is saved.

Description

technical field [0001] The invention relates to a gas water heater device, in particular to a gas water heater descaling device and a descaling method using the same. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. Gas water heaters have entered thousands of households. Generally, the water heater has smooth flow of water, rapid heating and easy temperature adjustment. However, if the gas water heater is used for a long time, a layer of scale will accumulate on the heating surface of the heating body. The thicker the scale will seriously affect the heat transfer of the heating surface, the heat transfer coefficient will be greatly reduced, and the gas consumption will be increased. , increasing the living expenses of residents, causing energy waste to the w...

AI Technical Summary

Problems solved by technology

[0003] At present, the gas water heaters used by residents do not have the function of descaling, and due to the special pipeline of the water heater, it is difficult to achieve the expected effect by using ordinary methods for descaling at home.

First remove the water heater from the wall where it is installed, unscrew the bolts to open the shell, and take out the water tank as a whole from the water heater. After...
