Gas wall mounted boilers are a good choice for both heating and providing hot water for households.

However, wall mounted boilers are very precise equipment with high technological content. There are many aspects to pay attention to during use, such as water pressure issues and the impact of gas pressure on wall mounted boilers.

What is the impact of water pressure on wall mounted boilers?

1. The water pressure of the wall mounted boiler is either high or low

The principle of wall mounted boiler is to heat the medium with a heat source, and then transfer the heat to the required place through pipelines. The medium that conducts heat is water. During the use of wall mounted boilers, water is in a flowing state, and it is normal for the water pressure to change slightly at this time.

There may be some air in the pipelines of the heating system, and there may also be air components in the water. The wall mounted boiler system during operation will continuously exhaust air from the exhaust valve, causing a certain degree of water pressure fluctuation. In addition, due to the relationship between thermal expansion and contraction, the volume of water heated increases, and the water pressure also increases accordingly.

What is the optimal water pressure?

The optimal operating water pressure is 1-1.5 bar

The normal water pressure of a wall mounted boiler is between 1-1.5 bar. If it is too low, it may cause the wall mounted boiler to not work properly; If it is too high, it may increase the wear and tear of the water pump, which is more directly manifested as water leakage. Therefore, when using a wall mounted boiler, attention should be paid to changes in water pressure.

When the water pressure is below 1 bar, water replenishment is required, and when the water pressure is above 2 bar, pressure relief is necessary.

After the system is replenished with water, it is necessary to turn off the water replenishment switch of the wall mounted boiler. Users who are on long-term business trips should turn off the main water supply valve. In short, excessive or insufficient water pressure can have negative effects, and a reasonable water pressure is the scientific method for using wall mounted boilers.

What impact does gas pressure have on wall mounted boilers?

Everyone knows that the gas pressure value at home is determined by the gas company after the gas is turned on, but due to multiple factors such as varying lengths of pipeline transportation, the gas pressure to each household is not absolutely the same.

1. If the gas pressure is too high, it may cause the gas wall mounted boiler to fail to ignite and use normally; It may also cause an increase in the actual gas input power for heating, shorten the service life of wall mounted boilers, and increase operating noise. Not only that, it will cause an increase in the actual amount of gas entering the gas wall mounted boiler per unit time, an increase in power, a malfunction in the temperature control of the bathing hot water (the actual temperature exceeds the set temperature by a lot), and a high water temperature exceeding the set temperature, causing inconvenience to users.

2. Low gas pressure can have two effects. Firstly, the wall mounted boiler cannot ignite. Secondly, it causes the wall mounted boiler to fail to reach its rated design power, prolonging the working time during heating, accelerating the aging of components such as fans, water pumps, heat exchangers, and burners, and even failing to achieve ideal heating effects. For hot water for bathing and daily life, low gas pressure may cause the hot water temperature to not reach the set water temperature, affecting its use.

Someone said: Can't wall mounted boilers automatically adjust the gas pressure value? The range and ability of gas wall mounted boilers to regulate gas pressure fluctuations are limited. In the case of exceeding or falling below the allowable range of regulation values, what we can do is to use gas wall mounted boilers correctly to prevent explosions.

Explosion refers to the loud "bang" sound that occurs when a gas wall mounted boiler ignites, resulting in an explosion. This phenomenon is caused by insufficient air pressure. During the first ignition, due to the low air pressure, the fire was not ignited, and during the second intake, the air volume was too sufficient, which could lead to detonation.

1. Remove carbon deposits. After carbon deposition on the ignition needle or burner, it may sometimes cause detonation during ignition, and maintenance personnel must be asked to clean it.

2. Check the battery. When the battery power of the flue gas generator is insufficient, it cannot ignite normally, causing gas to accumulate and cause explosion. It is necessary to replace the battery with a new one (pay attention to the positive and negative directions during installation).

3. The gas source needs to be adapted. According to different gas sources such as natural gas, liquefied gas, and artificial gas, a wall mounted boiler can only adapt to the same gas source. Gas wall mounted boilers must be professionally installed by professional maintenance personnel from reputable manufacturers.

4. Eliminate non-standard installation. Incorrect installation of air and smoke pipes may result in air leakage and combustion upon contact with a fire point.
