Does low water pressure and air pressure affect the use of wall hung boilers

The working pressure of the wall-hung boiler is generally above, and this number refers to the minimum working pressure of the heating pipe. If the furnace you buy has a pressure switch, when the water pressure is lower than the minimum working pressure, the wall-hung boiler will not work (as long as the water is replenished to the heating pipe when the water pressure is normal, the wall-hung boiler can work normally); For the wall-hung boiler with domestic hot water function, the water pressure is small and the domestic hot water may not be produced, because the pressure is small, the water flow is small, and the water flow sensor on the wall-hung boiler of many brands is flow-type, and the signal value does not meet the requirements, and the control system will not control the ignition of the wall-hung boiler, which is mainly to prevent overheating and dry burning. If the flow rate can be reached, it will almost work.

Gas pressure is not a problem, the rated pressure of the civil natural gas pipeline is 2000Pa (20cmh2O), 1000Pa wall-hung boiler can be burned, the low pressure will only affect the size of the fire, the output power is insufficient, resulting in the heating temperature can not go up, but the low pressure is mainly in the peak of gas consumption, such as afternoon meal time. For the heating of the room is basically unaffected. Unless the pressure in your home is low 24 hours a day, which is a common phenomenon, then you have to let the natural gas company increase the pressure.

Besides, your house is on the 7th floor, and the specific gravity of natural gas is greater than that of air, and the pressure upstairs must be a little greater than the pressure downstairs.

Water pressure: the minimum required action pressure of the wall-hung boiler is bar (kg, that is, kilograms), as long as the water pressure of the wall-hung boiler is increased to , that is, kilograms during the initial commissioning), the tap pressure is not enough, the manufacturer usually uses a self-priming pump to assist the user to pressurize, the initial stage of commissioning within 3 days to a week, the water pressure may be unstable, you can use the pump to pressurize at any time, after the water pressure is stable, the pressure of the wall-hung boiler heating system will be maintained at this water pressure, which can usually be maintained for 2 months to a heating season, if the water pressure shown by the wall-hung boiler water pressure gauge has been 1——, No matter how much external pressure is, the wall-hung boiler can be heated normally, but if the water volume is too small, it is more problematic to use hot water. Usually, the wall-hung boiler has a minimum water flow rate of 3L minutes, that is, when the water flow is less than 3 minutes, the wall-hung boiler cannot provide hot water.

Gas pressure: usually the proportional combustion wall-hung boiler has higher pressure requirements, when the natural gas pressure is lower than 1500pa (equivalent to 150mmh20, that is, 150 mm water column), it can not be used normally, if it is a sectional combustion wall-hung boiler, as long as there is more than 400pa (equivalent to 40 mmh20, that is, 40 mm water column) above the air pressure, as for the air pressure in your home, you can let the natural gas company to test, you can also let the service staff of the wall-hung boiler after-sales outlets test. Then make a decision on whether to buy and what configuration to buy a wall-hung boiler.

To sum up, the impact of water pressure on the wall-hung boiler is not fatal (as long as it can reach the above, the minimum can not be lower, and then it will affect the life), the key is the gas pressure, which determines your winter warmth!

The flow stabilization device is specially designed inside the wall-hung boiler system, and when the water flow rate changes due to the fluctuation of water pressure and air pressure, the water flow rate can be adjusted according to individual needs. It will not affect the use of wall-hung boilers! More knowledge of wall-hung boilers can be reached.

Let's take a look.

You have to find a professional to test it.

When wall-hung boilers. When the water pressure pointer is lower than the red warning line, it is particularly prone to dry burning, and after a long time, the wall-hung boiler will be seriously damaged by loose skin, and even need to replace the wall-hung boiler. At the same time, users should pay attention to the fact that when there is no one at home for a long time, they should do a good job of anti-freezing measures for the wall-hung boiler to prevent the wall-hung boiler from being frozen due to the freezing of warm water, which will affect the daily life needs.

In the face of the low water pressure of the wall-hung boiler, the wall-hung boiler should be turned off, the power supply should be cut off, and then the heating system should be checked for water leakage to ensure that the inside of the system is completely sealed, and then rotate the handle of the water injection water replenishment valve counterclockwise for a circle, and at the same time observe the change of the water pressure gauge, when the water pressure gauge pointer falls between, clockwise.

Tighten the handle of the water filling valve, and finally turn on the wall-hung boiler.

Most of the wall-hung boilers (including different brands) are used in kilograms (that is, the pressure gauge on the pressure gauge as the protective pressure value of the machine operation, as long as the water pressure is higher, it can be used with confidence, and the machine will be shut down if it is lower; There are also a few models that are protected by differential pressure, and the pressure value is slightly lower.

As long as the boiler is operating normally, there is no shortage of water, the water pressure gauge is to remind the user of the size of the water pressure in the boiler system, which is convenient to confirm when replenishing water, the boiler has water shortage protection, if there is a lack of water, the boiler does not work.

If there is no error, you can use it. Some manufacturers add a water pressure switch to the system, and if it is below a certain pressure, it will directly stop the fire and report the error.

It doesn't matter, as long as the water pressure is higher, you can use it with confidence.

Summary. Dear We will be happy to answer your <>

The air pressure of the wall-hung boiler will drop. The wall-hung boiler has a heating function, and the wall-hung boiler can be depressurized by discharging water to the heating system and reducing the pressure. Close the water supply valve of the wall-hung boiler first, then open the exhaust valve on the floor heating water separator or the exhaust valve above the radiator, and wait until the pressure of the wall-hung boiler is reduced, and then close the exhaust valve.

Hello dear <>: The air pressure of the wall-hung boiler will decrease, which may lead to a decrease in water pressure, and there are three main reasons. 1. If the sealing of the pipeline is not tight, it is easy to cause water leakage and cause the water pressure to drop.

Therefore, it is necessary to check whether the pipe of the wall-hung boiler is leaking, and if there is water leakage, it is necessary to make up the leakage in time. 2. There is gas inside the wall-hung boiler, which will cause the water pressure to drop. In the process of replenishing water, it is easy to mix some gas, so it is necessary to open all the exhaust valves that are flushed by Tongyin, and then close after the gas is discharged.

3. If there is no timely replenishment of water, it will lead to water shortage and water pressure drop. You need to open the water replenishment valve of the wall-hung boiler, and add the appropriate water to carry the crack, and wait for it to be added.

Without any impact, there is now a protective structure design.

When the ignition switch of the wall-hung boiler enters the working state, the fan starts first to form a negative pressure difference in the combustion chamber, and the wind pressure switch sends the finger to the pump, and after the pump starts, the water flow switch sends the instruction to the high-pressure differential punch electrical appliance and sends the instruction to the gas proportional valve after starting, and the gas proportional valve starts to start.

The gas proportional valve and the wind pressure switch and the flue gas induction switch are interlocked, the combustion chamber has a certain negative pressure gas, the proportional valve can work, when the flue gas induction switch can not detect the exhaust gas discharge in 5 seconds, the gas proportional valve will be cut off to stop the gas supply, so as to ensure the safe use of gas.
