How to detect floor heating leakage and what are the detection methods?

See if the underfloor heating is leaking? No need to pry the floor tiles.

It only takes 1 step and 1 second to do it!

Home decoration floor heating, what are you most afraid of? Most of them are afraid of floor heating leaks. For example, something like this:

In the traditional concept, once the floor heating leaks, it is indeed very troublesome, you need to pry the floor tiles, especially the tiles, to pry and do not make up, it is very troublesome, not to mention the impact on the life of the family, but also may bring inconvenience to the life of the neighbors.

So, how to quickly tell if your home floor heating is leaking? If there is a water leak, do you really have to go to great lengths to pry a lot of floor tiles? Below, Jiayue Wangzai.

Let's give you a science popularization topic.

1. Look at the pressure gauge.

1 second to confirm whether the floor heating is leaking.

In home decoration floor heating, a wall-hung stove is generally used.

Come and bring underfloor heating. The wall-hung boilers all have a pressure gauge that shows the pressure of the underfloor heating system at all times. The underfloor heating system is a sealed circulation system.

There is a little water in the pipeline that is constantly circulating, and there are valves at the connection between the wall-hung boiler and the tap water that remain closed for a long time, and the wall-hung boiler also has a water replenishment valve, which also maintains a water replenishment state for a long time, so that the double guarantee ensures that your floor heating system is a little water, but whenever there is a little leakage, it will be seen through the pressure gauge of the wall-hung boiler.

If the pressure gauge of your wall-hung boiler is lower than 1, the system will not work. You have to look at the position of the pressure gauge pointer, and at the same time, see if your wall-hung boiler has been replenishing water every once in a while, if so, you should consider the possibility of leakage in the floor heating.

2. The floor heating is really leaking, no need to panic, no need to pry the floor tiles in a large area.

Some people are very worried about the leakage of floor heating, to pry the floor tiles at home, in fact, this is the past practice, especially in the manual experience or past means, it is difficult to find the leakage under the premise, then there is only a large area of pry wood floors and tiles.

But what age is it now, it is a high-tech era, you use a thermal imaging instrument to hit, you can accurately find the leak point within a few minutes, only need to pry and repair at most one tile, you can get the floor heating leakage work.

3. Should the floor heating leak? Normal should not leak.

Here Jiayue Wangzai must remind everyone that floor heating should not leak, at least, in the absence of man-made damage or other non-majeure damage, the floor heating pipe should be more than your home decoration hot and cold water pipes are less leaky, your home decoration of hot and cold water pipes have many joints, and the floor heating pipe in your underground is not any joints!

To install floor heating, the pressure must be maintained throughout the process. In the north, developers concentrate on the installation of floor heating, and it is unknown whether it is standardized and suppressed. But in the southern region.

Home decoration floor heating must be maintained in the whole process, and if the pressure is not right, it is necessary to make up the pressure and check it in time. Once your tiles and wooden floors have been laid, you can observe the pressure through the boiler pressure gauge. Under normal circumstances, underfloor heating will not leak, even if the water leakage is damaged by man, there is no need to worry about large-scale damage to tiles and wooden floors.

In the southern region, in addition to paying attention to whether the floor heating is leaking, we should also pay attention to the energy consumption in the later stage of floor heating, and do a good job in floor heating insulation.

Floor heating leakage can be detected, the detection adopts the method of measuring the pressure drop, that is, the pressure gauge is installed on each floor heating pipe in turn, and then the water is injected and pressed, and when the pressure rises to a higher value, stop the pressure, after 24 hours of stationary, observe whether the pressure changes, if the pressure does not change, it means that the floor heating pipe is not leaking, if the pressure value drops significantly, it means that the pipeline has a leakage, and the next step is to carefully find the leakage point in**? It is then processed.

Hello, glad to answer for you! The way to detect the leakage point of floor heating: 1. Check the connection of any pipe at the connection of each manifold is the most frequent location of water leakage, and the connection of the metal parts of the floor heating and the connection between the manifold and the coil is a high-incidence area, which is easy to cause water leakage at the interface.

2. After the pressure test excludes the connection parts, you can judge whether the floor heating pipe is leaking through the pressure test. Close the main valve of the floor heating, press the floor heating with a manual press, and wait for half an hour when pressing 8 10 kg. If the pressure can be kept without dropping, it means that the heating pipe is not leaking.

Under normal circumstances, if it is confirmed that there is a leak in the floor heating, the pressure gauge will generally drop pressure in a short time. 3. Determine the water leakage circuit to open the valves of each circuit respectively, and observe which circuit has a pressure reduction phenomenon, and the circuit with a significant pressure drop is the water leakage circuit. After confirming the leakage circuit, shut down all the circuits that have no leakage, and then fill the floor heating pipe with water, adjust the water temperature to the highest temperature, and circulate the floor heating water.

4. Confirm that the water leakage point gradually rises with the extension of time, and the surface temperature gradually rises, and the amount of hot water at the water leakage point is more than the normal position, and the heat is also higher. When the leakage point area is determined, the center point should be determined, and the location of the center of the leakage point is usually the place with the highest temperature. Based on this, the user can roughly determine the center of the leakage, and then carry out a small area of ground excavation, and check and repair the floor heating pipes.

In addition to this, we have the option of using an infrared imager for testing. With an infrared imager, the leak area is scattered and brighter. The normal underfloor heating area is dark red, and the leakage point is bright white and easy to identify.

By looking at the pressure gauge, you can know that if the floor heating leaks, the pressure gauge will decrease, and the pressure gauge value will drop significantly.

Generally, serious water leakage will lead to water leakage downstairs, if the downstairs ground runs to the door and says that there is a water leak, and the leakage part is not a toilet, it means that the floor heating is leaking, and it will also lead to water on the indoor ground. If it is a relatively small water leakage, it is generally not visible, and it needs to be found with the help of other tools, and the pressure gauge can generally be observed to judge whether there is a water leakage.

Observe whether there is a change in the floor heating pressure gauge when the floor heating is working, if it is a slow leakage, first stop the pipe from working and cool it to normal temperature, when the floor heating temperature is cooled to room temperature, inject hot water into the floor heating pipe to increase its pressure, so that you can test it by closing the valves on each water separator, and observe the pressure gauge.

The easiest and fastest way is to use a floor heating leakage imaging camera, which can be done for a basic thousand yuan, and in addition to floor heating leak detection, it can also be used in other temperature measurement scenarios, which is very cost-effective for multiple uses.

In the cold heating season, the most feared thing is the "running and dripping" of heating facilities. After the long-term use of heating facilities, a large number of microorganisms and calcium and magnesium ions in the water produce biological sludge and carbonic acid compounds attached to the inner wall of the pipeline after heating, hindering the heat transfer of heating equipment to the house, causing blockage in serious cases, resulting in the phenomenon of "running and dripping".

Once there is a "running and dripping leakage", the traditional leak detection method is to press each pipeline, and judge whether the pipeline is suspected of pressure loss and leakage through the change value of the pressure in the pipeline over a period of time. The biggest problem with this method is that it can only judge which floor heating coil may leak, and cannot accurately locate the location of the leakage point.

If you want to do a good job, you must first sharpen your tools. The traditional "look, smell, touch" method is no longer efficient, and advanced professional diagnostic tools will become a must-have for HVAC engineers. The use of thermal imaging technology can help HVAC engineers comprehensively capture the temperature distribution of the tested pipeline, quickly find abnormal points, and make accurate judgments and positioning.

Hikvision H10 Thermal Imaging Leak Detector.

Hikvision Micro Shadow H13 Thermal Imaging Leak Detector.

Since the release of Hikvision's visual temperature measurement thermal imagers H10 and H13, with many of their own characteristics, they have become the "hot" tools in the HVAC leak detection industry.

After the plumbing pipes in the floor are blocked or leaked, the Hikvision H10 thermal image leak detector can quickly scan the floor to quickly find and locate the floor heating blockage or leakage point, reduce the owner's loss, and accurately dig to repair the blockage or leakage.

1. The waterproof layer of the outer wall of the building is cracked.

In this case, it is generally leaking that the outer side of the corner is the outer wall of the building. Otherwise it can basically be ruled out.

2. Floor heating leakage.

Generally speaking, each circuit of the floor heating pipe should be a whole pipe from the water inlet to the water outlet, and there is no joint in the middle, but it is not excluded that the workers will cause damage to the floor heating pipe in the process of construction, and the damage will be connected by hot melt welding, which will lead to leakage at the joint of the pipe. (The floor heating pipe itself will not leak, and most of the leaks are at the joints).

Exclusion method: Exclusion by suppression test. If the pressure drop is less than MPa, basically the leakage of the heating pipe can be ruled out.

3. There is leakage in the buried water pipe in the bathroom.

There is a leak in the buried water pipe joints in the bathroom, especially where the walls meet. This can also be ruled out by suppression testing. This can also be ruled out if there is a leak at the downstairs leakage point, in the corner of the outer wall of the bathroom that is not downstairs.

4. The waterproof layer of the bathroom is cracked.

Similarly, if there is a leak at the downstairs leakage point, in the corner of the outer wall of the bathroom that is not downstairs, this situation can also be ruled out. If there is a leak in the corner of the outer wall of the downstairs bathroom, it may be a crack in the waterproof layer, and it can be checked by a closed water test.

Observe the change of the pressure gauge Under normal circumstances, if it is determined that the floor heating is leaking, the pressure gauge will generally lose pressure in a short time, when it is determined that it is a slow leakage, the first thing is to stop the operation of the pipeline, after the floor heating surface is cooled, after the pressure is injected with hot water, the valves on the water separator are closed respectively, and the pressure gauge is observed to determine that the pressure gauge has not changed. Determine the water leakage circuit Open the valves of each circuit separately and observe which circuit has a pressure reduction phenomenon, and the circuit with obvious pressure reduction is the water leakage circuit. After determining the leakage circuit, close all the circuits without leakage, and then fill the floor heating pipe with water, adjust the water temperature to the maximum temperature, and circulate the floor heating water.

At this time, the pressure gauge will gradually decrease, when heating, pay attention to maintain the pressure value of the floor heating pipe, after the leaking floor heating circuit is activated, and then use the infrared thermometer to measure the surface temperature. During the initial measurement, it will be found that there will be a certain temperature difference on the surface, and this temperature difference is generally linear, that is, the direction of the floor heating pipe laying during installation. Determine the leakage point With the extension of time, the surface temperature gradually rises, and the temperature of the identified leaking pipe will rise very high, and a peak will be formed at the leakage point, where the temperature of the leakage point will be much higher than the temperature value of other parts of the pipeline.

When the leakage point area is determined, the center point should be determined, and the position of the center of the leakage point is usually the place with the highest temperature, according to which the user can roughly determine the center position of the water leakage, and then a small area of ground excavation can be carried out to inspect and repair the floor heating pipe.

You can ask a special maintenance master to take a look.

Check that there is no leakage in the area, which means that the water pressure is not enough.

After installing underfloor heating in your home, you need to carry out quality inspection to avoid water leakage. How to detect floor heating leakage? PChouse will take you to find out.

1. Use the pressure gauge to observe whether there is water leakage. Observe whether the pressure gauge of the geothermal heat changes when the geothermal work is working, if the geothermal water will leak, the pressure of the pressure gauge will decrease, and the value of the pressure gauge will drop significantly. If the geothermal heat is leaking slowly, then the pipe should stop working and cool to a normal temperature, then inject hot water into the geothermal pipe to increase the pressure, and then close the valve on each water separator to observe the pressure gauge.

2. Determine the leaky room. Next, we need to open the valves of each return pipeline, and then observe the phenomenon of circuit pressure reduction, the circuit with obvious pressure reduction is leaking, and after knowing the circuit, we can determine which room has geothermal water leakage.

3. Determine the approximate area of water leakage. The room temperature is heated to a constant temperature, then the geothermal temperature is controlled at the same temperature, and then the infrared tester is used to measure the temperature of each area of the room. If the temperature in some places is irregularly distributed, it means that the leak area is in this area, because the temperature of the leak will be higher than in other places.

The hot water coming out of the leak will come into direct contact with the floor, causing the floor to be warmer than other pipes that are separated by the pipes, so that the specific area of the leak can be determined.

4. Find the leakage point. After finding the leakage area, we need to find the specific leakage point, the temperature at the center of the leakage is the highest, and the infrared tester can detect the leakage at which location, and the repair can start after determining the leakage point.

Summary. Floor heating leaks can be checked by:

1.Check by suppression test.

2.Confirm by looking at the pressure gauge.

3.Observe the water situation on the ground.

After determining that it is a water leak, you can immediately close the inlet and return valves of the floor heating, and then let professionals come to repair it.
