It is believed that there are water heaters in every family. Gas water heaters are still used in most households. Today we will share with you the gas water heaters and the problems they should pay attention to when using them. Gas water heaters refer to fuel gas as fuel. , By means of combustion heating, the heat is transferred to the cold water flowing through the heat exchanger to achieve a gas appliance for the purpose of preparing hot water.
For any type of water heater is a combination of advantages and disadvantages, gas-fired water heater is no exception, its popular love and use is not without reason, but this does not mean that it is flawless. For most people The advantage of gas-fired water heaters is that they are ready to use, no need to wait, save more time for users, do not need to wait too long for the water to warm up before they can use it to reach their own desired temperature. In addition, gas-fired water heaters account for The area is small and it is a good choice for those who do not have enough space.
However, gas-fired water heaters also have some disadvantages that cannot be ignored. Compared to electric water heaters and solar water heaters, the safety factor is not high enough, and gas-fired water heaters are prone to frequent gas switching and gas leakage. This becomes a gas-fired water heater. The main reason for the declining rate year by year. In addition, gas-fired water heaters are inconvenient to install. Here we provide some solutions to common problems and causes of gas-fired water heaters:
Problem 1: Water is not hot
It is common for gas-fired water heaters to suffer from water insufficiency, which is usually due to gas pressure problems. The gas pressure is low: the gas line is blocked and the pressure in the gas line is low; at this time the user can check if the gas line is blocked (from the gas meter Connect a pipe to the gas inlet of the water heater and directly connect it to the water heater. If the water heater can work normally, that is, the pipeline from the meter to the inlet of the water heater is blocked), or ask the gas company to check the gas line pressure.
In addition, excessive water flow will also lead to lower water temperature. In the case of excessive water flow, the pipeline pressure is too large, and the pipeline diameter is too large to cause a lower water temperature. Residents can close the inlet valve and improve the water heater. The set temperature.
Question 2: The water temperature is too high
Like the first problem, there is a certain correlation between excessively low water temperature and high water temperature. Common causes of excessively high water temperature caused by low water pressure. Low water pressure, low water flow, and clogged water pipes: In order to relieve the water pressure problem, the user can install the water pipe. Replacement to a certain diameter;. Install booster pump;. Clean water heater inlet pipe filter; Adjust the amount of water on the water heater to adjust to large; or exchange shower, shower eyes should try to get the Ambassador to get larger water, lower water temperature.
In addition, it is the gas pressure problem. The high gas pressure is mainly reflected in the liquefied gas (LPG); users need to replace the liquefied gas pressure reducing valve (must be labor card), adjust the gas pressure to the required value, in order to reduce the water temperature.
Question 3: After the water heater is lit, there is a period of cold water. After re-watering, there is a period of cold water.
Unpredictable water temperature is also one of the common problems of many gas water heaters. Generally, these problems are mainly the characteristics of strong exhaust water heaters, not faults. Strong exhaust air heaters are used to increase the safety of users before the water heaters are lit. The pre-sweep is set. After the water heater is turned off, it is cleaned and the exhaust gas in the water heater is discharged from the water heater. As a result, there is a period of cold water after re-watering.
In addition, due to the length of the water from the user's faucet to the water heater outlet, and the time required for the water heater to heat the cold water to the hot water, there is a period of cold water after the water heater is lit. This period of time can be shortened before use. Set the water heater first to high temperature, and then set the water temperature to the required temperature after the water and heat are applied. This will avoid similar problems.
