Floor heating has a lot of gas every day, what to do if there is always gas in floor heating

The use rate of floor heating in life is getting higher and higher, but do you know how to check the quality of floor heating? With floor heating, the home is still cold, what's going on? Lin Bing HVAC tells you: gas accumulation, debris, and reverse connection of water supply and return pipes are all possible causes.

One of the reasons: gas accumulation It is understood that before the start of each heating, the heating pipeline system in the residents' homes is not running for a long time, and there is often gas in it, which will lead to poor circulation of hot water and radiators.

It's not hot. To solve this problem, just open the air running valve on the radiator, release the gas in the pipe, and the hot water will flow over, and the radiator will heat up. In addition, some residents forget to open the outlet valve under the pipe, and the hot water cannot be circulated, so do not forget to open the outlet valve when the heating starts.

Reason 2: Debris According to reports, when many maintenance workers go to residents' homes for exhaust debugging, many people will find that the water flowing out of the heating pipe is black and contains a lot of impurities, and it will take more than half an hour for clean water to flow out. These impurities, all caused by fine sand or pipe rust, accumulate in the pipes and affect the hot water circulation of the heating system.

Therefore, the impurities in the pipes should be flushed out by water at the beginning of heating.

Reason 3: The water supply and return pipes are reversed It is understood that some users will connect the water supply and return pipes when they are privately connected to the heating pipes, or the developers will connect the water supply and return pipes in the reverse when building houses, resulting in hot water and cold water"Top cattle"The hot water circulation could not be realized, and the heating was not hot, and in this case, the heating facilities had to be reinstalled.

However, the heating company Lin Bing HVAC reminds you that when the radiator is not hot, it is best to contact the staff of the heating company to debug and repair it, so as not to cause water running and other phenomena and affect work and life.

Hope it helps!

Install an automatic exhaust valve, generally installed at the top of the main (vertical) pipe system between the corridors, you can check whether there is, whether it is blocked, if not, you can install one, about 10 yuan.

The general rule of thumb is that there is often an air blockage in the system.

The reason is that the boiler room should be "removed from fire and depressurized" at night to reduce the temperature of the system and save fuel. When the pressure of the system is reduced, a large number of bubbles are often formed. When the bubbles enter the system, they keep moving upward, and if they are too much, they will form an "air blockage".

These phenomena are usually caused by design flaws in the heating system. The solution is to install an automatic exhaust valve, which is often called "running wind".

Air block: Just install an automatic exhaust valve.

Floor heating always has gas that needs to be vented, and the air in the pipes is thoroughly deflated and drained in order to drain the air from the pipes.

Preparation tool: one empty plastic bottle.

1. After confirming that the upper water inlet main valve and the lower water outlet main valve are closed (the switch direction is perpendicular to the water pipe as shown in the green box in the figure), unscrew the air release valve (shown in the red box) of the upper water inlet pipe by hand. (If the switch main valve is not closed, it needs to be manually closed before it can be released).

2. Then unscrew the air release valve of the lower discharge pipe by hand.

3. Unscrew the first valve in charge of the upper discharge inlet pipe for degassing.

4. Close the valve after the first water inlet pipe is deflated, and degas the other water pipes in turn as shown above.

5. After all the inlet water is deflated, open all the valves in the water inlet pipe. According to the inlet water sub-division and degassing steps, the lower discharge water sub-division is also deflated.

6. After the water outlet pipe is deflated, open all the water distribution pipe valves as well.

7. After all the inlet and outlet water pipes are deflated, the water can be discharged (the water discharge is to determine whether the air in the pipeline is discharged). The discharge of water needs to be carried out in groups, close the valves of the remaining four groups of inlet and outlet water pipes, and only open one group of water inlet water pipes and water outlet water pipe valves.

8. Close the air release valve on the water inlet pipe, and connect the empty plastic bottle to the water outlet below the air release valve on the water outlet pipe.

9. Open the main water inlet valve, the water outlet of the exhaust valve below will release water, and the smooth water connection of the plastic bottle means that the first component of the water pipe has been completely exhausted.

10. Close the first valve of the lower water pipe (green frame), and the valve of the water inlet water pipe does not need to be closed, open the second group of water pipe valves for the second group of water pipe drainage.

11. After draining the water pipes of the remaining components in turn as shown above, turn off the air release valve on the water pipe.

The gas in the floor heating pipe is due to the gas cohesion in the floor heating pipe, which causes the water circulation to stagnate, which will affect the heating effect, so it is necessary to deflate.

Generally speaking, the reasons why the floor heating is not hot are that the pipe pressure is not enough, there is gas in it and the filter is blocked, and if the pressure is not enough, it is best to find a heating company to solve it; If there is gas in the pipeline, you only need to use the gas release valve to open the gas in the pipe and release the gas.

You can exhaust the air, open the exhaust valve on the water separator and the water collector in turn, and listen to whether there is any air flow sound; Then open and quickly close the valve of the ball valve on the circuit below the water separator, and listen to whether there is any air flow sound, which is called leak detection, and you can find out whether the pipeline is damaged in the process of decoration.

Due to the cohesion of the floor heating pipe and the stagnation of water circulation, affecting the heating effect, you can adjust the setting of the floor heating exhaust valve, each group of radiators are installed at the end of the manual release valve, the action should be small when deflating, in case of breaking, slowly twist the exhaust valve, and release until the water is discharged.

Do water separators have exhaust valves? Central heating or gas furnace heating?

Just open the one with qi, close the others, force the circulation, and forcibly bring the qi out.

It will not always be a copy of the gas, tell you the thorough exhaust method steps, close the valve below, that is, the outlet valve, and close all the valves of the branch pipe.

Then after opening one of the branch valves, after a few minutes of circulation, open the exhaust valve on the water collector, the water outlet position, and then close the exhaust valve and branch valve.

Perform the degassing of the next branch pipe in turn.

After all the backwater pipes are discharged in turn, open all the backwater main pipes and branch pipe valves. The most common thing we encounter in geothermal maintenance is the consultation on degassing, which we hope will help you and those who work in geothermal cleaning.

An automatic bleed valve can be installed

It is by using a little electricity to absorb a low heat energy in the air to heat the water through a circulating pump to circulate the water, which is probably the case.
