How do you clean underfloor heating pipes?

Underfloor heating. 1 2 Step by Step Reading.

Now floor heating has been very popular, most residential areas will take the way of floor heating, but after the use of floor heating for a long time, it is inevitable that there will be dirty things attached to it, affecting the heating effect.

Because the dirt is attached to the inside of the pipe, it is difficult to clean it up with the general cleaning method, and today I will teach you how to clean the floor heating pipe.

Use of chemicals.

Chemicals used to clean up floor heating are available in many places, and we can also buy them directly through the Internet, and pour clean water into the floor heating pipes first, so as to rinse out the dirt that can be cleaned with running water.

Then inject chemicals into the floor heating pipes, soak them for the corresponding time according to the instructions, and then call the water outlet to clean up the chemicals after reaching the corresponding time.

In fact, you will find that a lot of dirt in the pipes has reacted with chemicals, and the liquid discharged is very dirty, and then you can fill it with clean water again.

Physical pulse wave cleaning.

Physical pulse wave is the most common way to clean up dirt, if the floor heating pipe layout in the home is more reasonable, there is no right-angle angle, this way can achieve good results.

However, if the floor heating pipes in the home are more complicated, it is not recommended to use this method to clean the floor heating pipes, because if the corners are acute or right-angled, it will affect the flow of water and the cleaning effect is not good.

If you want to clean the floor heating pipes, they have professional cleaning of the floor heating pipes, and they use electromagnetic pressure pumps, so that they can be more sober.

Steps to clean underfloor heating:

1. Keep the main valve of water inlet and drain and the valves of all branches in a closed state.

2. Use a wrench to unscrew the screw plug of the return section. There may be a slight overflow of water during the unscrewing process, which can be padded underneath with a towel.

3. Use scissors to cut a rectangular hole above the back end of a large plastic bottle, and place the rectangular hole end of the bottle under the screw plug that has just been unscrewed.

4. Open one of the split valves. Slowly unscrew the main water inlet valve (red box) and keep the main return valve (green box) closed, at this time the plug connected to the plastic bottle will discharge water.

5. Until the sewage connected to the plastic bottle becomes clean water, the floor heating water pipe of the road will be cleaned, and the other water pipes can be closed and opened in turn for sewage discharge.

6. After all the branches are cleaned, you can screw back the screw plug and open the total water inlet valve and the total return valve. Open the valves of all the branches, and you can use the floor heating normally.

Please use a floor heating cleaner, add limescale detergent, connect the floor heating pipe to run for 30 minutes, and then rinse with clean water.

Generally speaking, there are three kinds - chemical soaking, projectile cleaning, and pulsed wave physical cleaning. Among them, the pulse cleaning method is the most used for floor heating, which can clean the scale and impurities of the floor heating pipe and water separator at one time.

Floor heating cleaning is generally calculated by the square, according to the heating area of geothermal heat, now it is generally 5-15 yuan a square is more reasonable.

There is also a kind of calculation according to the circuit, a circuit is basically 50-150 yuan, now most of the cleaning unit door-to-door cleaning costs are basically like this, different companies ** way is different.

For example, in Hangzhou, for example, the cost of cleaning a house with a heating area of 80 square meters is about 300 to 700, depending on the charging mode of the floor heating cleaning company, the cleaning institutions are different, the cleaning methods are different, and the cleaning fees charged are not the same.

For specific conditions, please call us or make an appointment for cleaning.

How to clean the underfloor heating pipes:

Before cleaning the floor heating, it is necessary to test run the floor heating system to ensure that the whole system of floor heating can work normally, avoid disputes after the damage of parts, and then start the cleaning and maintenance of floor heating. The specific operation process is as follows: power cut, gas and water cut-off for the boiler; Dismantle the boiler casing.

Drain the floor heating system through the boiler pressure relief valve or the manifold pressure relief valve; Remove the Y-type filter inside the boiler and rinse it under the faucet to restore; Dust and scale removal of combustion chambers, fans, plate heat exchangers, water pumps and other components inside the boiler; Remove the exhaust valve of the manifold and install the adapter.

Connect the water inlet and outlet of the floor heating cleaning machine with the water collector; Remove the solenoid valve on the manifold and open the valves of all circuits; Connect the power supply of the cleaning machine, select the cleaning mode of the cleaning machine, and turn on the cleaning machine limb to do the mold work.

After the floor heating pipe is cleaned, install the battery valve on the manifold circuit, restore the exhaust valve of the manifold, and restore the original state of the boiler; Inject water into the floor heating and add heating protector to the floor heating system; Finally, the effect of underfloor heating operation is tested.

In the process of floor heating cleaning, in addition to the commonly used disassembly and debugging tools, three professional tools are also needed: pulse cleaning equipment, high-precision water quality detector, and handheld industrial temperature measurement thermal imager. Pulse cleaning equipment (floor heating cleaning machine) uses the principle of air pressure pulse to quickly scour and clean the rust and dirt that have been slowly adhered to the inner wall of the floor heating coil and the impurities accumulated in the pipe.

The methods of cleaning floor heating pipes are: chemical immersion cleaning, projectile cleaning, and pulse wave physical cleaning.

1. Soak and clean with chemicals

This cleaning method can fully dissolve the slime adhered to the pipe wall, and the high-quality food-grade raw material preparation used will not cause corrosion to the floor heating pipes, and the cleaning is thorough.

The disadvantage of this cleaning method is that some market speculators often use low-cost strong acid preparations, which can cause corrosion to pipelines and related components.

2. Projectile cleaning

This cleaning method uses the friction between the cleaning bomb and the pipe wall to remove the slime attached to the pipe wall, and does not damage the floor heating pipeline, and the cleaning is more thorough.

The disadvantage of this cleaning method is that the underfloor heating pipes need to be disassembled. If there is a joint in the underground pipeline, the construction is very inconvenient and it is easy to make the cleaning bullet stuck in the pipeline. In addition, it may also cause secondary damage to the original manifold, valve and other related parts.

3. Pulse wave physical cleaning

This cleaning method does not require chemicals, does not disassemble the floor heating pipe, and cleans more thoroughly. Its unique cleaning principle can clean the main circuit and valve of the floor heating manifold at the same time, so as to avoid the phenomenon of valve blockage caused by long-term scaling.

The disadvantage of this cleaning method is that the construction is limited by space, especially the floor heating manifold of some users is installed in a hidden place, and the distance between the two ends of the manifold and the wall is too close, so that the construction is more difficult.

The importance of underfloor heating pipe cleaning:

After the floor heating pipe is used for a section, there will be scale on the inner wall of the pipe, which will adhere to the inner wall of the pipe, forming a pipe blockage, resulting in insufficient heat dissipation, which will seriously affect the heating temperature and effect. Practice has shown that every 1mm of dirt added to the inner wall of the floor heating pipe after one year of use will cause the temperature in the heating room to drop6.

This not only affects the normal use of floor heating, but also causes a waste of energy. In addition, the biological slime, impurities, scale, rust, pollutants, and other impurities in the external network pipes of the central heating system enter the households, and the accumulation in the floor heating pipe is another major factor that causes the scaling of the inner wall of the floor heating pipe.

To clean the pipes of the underfloor heating, you can use water pressure, towels or unclogging agents. When hydro cleaning, all the valves of the floor heating should be closed, and then the water inlet pipe should be opened in batches, and the stains should be discharged by pressure, and the towel cleaning needs to tie the towel to a string, and then stuff it into the pipe, constantly push and pull, or pour the dredging agent into the pipe, and rinse it after the reaction.

1. Water pressure washing

Underfloor heating pipes can be flushed with water pressure. First of all, all the valves of the floor heating pipe are closed, and then a plastic bottle with a rectangular mouth is placed into the water inlet, and then the water inlet valve is opened, and the stains on the inner wall of the water pipe are washed out by the pressure of the water bottle through the water.

2. Wipe with a towel

Underfloor heating pipes can be wiped down with a towel. First of all, after wetting the towel, wipe the dust on the surface of the floor heating pipe, then tie it to a rope, and use a wooden stick to stuff the towel deep into the pipe, then pull it out, and repeat the operation three times to clean the pipe.

3. Dredging agent treatment

Floor heating pipes can be cleaned with unclogging agent. Close all the valves of the floor heating pipes, then put the pipe dredging agent into the pipe, wait for half an hour, open the water inlet valve and drain valve, and put a plastic bucket at the outlet of the drain valve, waiting for the discharged water to contain foam, it means that the pipe is clean.

Due to the long use of the floor heating pipes, the inside needs to be cleaned with limescale. How to clean the floor heating pipes? PChouse will take you to find out.

1. Close the two sluice gates first, then open the drain outlet, drain the water inside, and then open the floor heating hot water inlet pipe;

2. Pour the floor heating pipe cleaning liquid into the floor heating pipe according to the instructions; Open the plug and connect the return plug with a plastic pipe;

3. Ensure that the floor heating pipe is filled with water, close the cold water valve, and start the circulating pump circulation 30;

4. Open the cold water valve and drain the turbid water;

5. Rinse the floor heating pipe with clean water until there is clear water flowing out of the outlet pipe and the cleaning work is completed. After flushing, close the hot water valve and remove the plastic pipes, and restore them to their original state before they can be used normally.

During the cleaning process, it is necessary to pay attention to the joints of the pipeline not to be damaged, and the joints are still operated in accordance with the specifications, and tightened to prevent water leakage. Secondly, because the house has been renovated and people have lived in it when the floor heating is cleaned, it is necessary to pay attention to cleaning and prevent dirty water from flowing around.

Floor heating can only be cleaned by professionals, and the cleaning methods generally include the following three methods: chemical immersion, projectile cleaning, and pulsed wave physical cleaning. Chemical soaking:

Chemical immersion can effectively clean the dirt of floor heating pipes, but most of the low-cost strong acid preparations on the market are used, which are easy to corrode pipelines and related components. <

Floor heating can only be cleaned by professionals, and the cleaning methods generally include the following three methods: chemical immersion, projectile cleaning, and pulsed wave physical cleaning.

Projectile cleaning: effectively clean the dirt without damaging the pipeline, but the manifold needs to be split and the cleaning bomb is easy to get stuck in the pipeline; At the same time, it is easy to cause secondary damage to the water collector, valve and other related parts.

CACS spiral pulse cleaning: The CACS spiral pulse cleaning technology used by the pipe cleaning machine can clean the floor heating pipes without dismantling the pipes and excavation, and carry out deep pulse cleaning of the pipes on the basis of ensuring that the relevant components of the pipelines are not damaged.
