The floor heating is not hot, and it is suspected that the pressure is small, so add a drain pipe to

When many people install geothermal heat, they are in order to have a better heating effect, but there are several reasons for the fact that geothermal heat is not hot, the first point is that there is no water discharge pipe in the place of the return pipe.

I didn't understand at first, the first year of installation of geothermal heat was not high, I deliberately found the installer, they suggested that I put a water outlet pipe in the place of the return valve, so that it can increase the effect of circulating water, in fact, this effect is that when we usually put the radiator, every time the heating is exhaust and water is a reason.

Therefore, after putting more water in the return valve, it is guaranteed that you will have an immediate effectOf course, after a few years of geothermal use, if it is not hot, the effect is not very good after drainage, in this case, it is very likely that there is too much dirt accumulated in the geothermal heat.

In fact, we know that the water used in geothermal heat is the tap water that we usually come into contact with, and the tap water still contains a lot of dirty substances.

After all, it is not pure water that accumulates over time that there will be a kind of precipitationSo the geothermal pipes are actually very dirty, so in this case, the floor heating will not be hot, so we need to find a professional cleaning company, they will make an effective cleaning of the geothermal pipes, and the effect is very obvious, all of them are some black and brown dirt.

The cost of cleaning up the geothermal heat is not too expensive, generally between 200 and 500 yuan, and the charging standard varies according to the overall area of the house. Excluding these two reasons, there may be a very scary thing, that is, the geothermal pipes of your home may be leaking in one place.

You have to go to after-sales treatment, because there are many reasons why the floor heating is not hot, such as air in the pipe, the water pressure is too small, the pipeline design is unreasonable, the pipeline is uneven, etc.

For example: the floor heating return pipe is not hot, blockage is a more common reason, learning to clean is a great benefit to yourself, so I also learned very seriously, the specific way is filtration cleaning, chemical cleaning and so on.

Step 1: Filter cleaning. First of all, close the inlet and outlet valves of the conduit at the connection, which is conducive to the pressure relief of the air release valve. Next, open the filter, then wash the filter clean, and check whether the filter is broken.

If the filter is broken at the beginning, you can replace it with a filter of the same specification.

2nd, Cleaning of chemicals. When it comes to cleaning chemicals, it is usually the use of chemicals, which are introduced into the pipes, and then soaked, so that the scale and stains in the pipes can come off, so that the pipes will not be blocked, and the water will flow smoothly. Use of cleaning agent.

There is a difference between cleaning agents and chemicals, which usually have the composition of corrosion inhibitors, which can fully dissolve the soil attached to the pipe wall without causing harm to the environment.

Geothermal return pipes.

There is still pressure, and if there is no pressure, then the geothermal heat cannot be used normally. The pressure of the return pipe will be greater than that of the inlet pipe. However, the pressure of the return pipe should also be controlled, too large will affect the use of Huiyan and the effect, so the exhaust work should be carried out regularly during use.

The geothermal return pipe has pressure, but if the geothermal return pipe has high pressure, it is abnormal. This may be due to the fact that there is air in the floor heating pipes, which causes the pressure of the water pipes to be uneven. Therefore, we should first exhaust the air from the geothermal return pipe before continuing to use it.

There is a certain pressure in the backwater, but it must be less than the pressure of the water supply.

Respond to your questions simply and directly about your personal point of view

2. First of all, close the main valve of the water outlet, and open the exhaust valve at the water separator until the water outlet of the exhaust hole discharges the air in the pipeline. Unscrew the Y-filter, take out the strainer and clean it.

3. If the situation you mentioned still occurs after the air is discharged, it can be determined that the pipe diameter design is unreasonable, resulting in excessive pipeline pressure and excessive water flow. Why? When I was a child, my home was heated by charcoal, and the next-door neighbor turned off the fire and came to borrow the fire, but what should I do if I don't have tongs at hand at this time?

Grab it directly with your hands... If the speed is fast enough, the fingers will not be hurt in any way. Because the heat transfer between the media requires a process, the heat has not yet been transferred to the hands of the coals from one brazier to another.

Similarly, when the hot water in your pipes passes through at a very fast flow rate, the heat exchange between the pipes and the hot water is minimal. The pipes absorb less heat and emit less heat, of course.

Solution: Properly close the outlet water valve to "hold" the water, reduce the flow rate of hot water in the pipeline, and prolong the residence time of hot water in the entire pipeline system.

4. Another question is, I don't know what the so-called "smooth" is when the water flow you described is smooth? The trickle is also smooth, and the jet is also smooth. It is recommended to close the valves of all branches at the water separator, and test the water all the way to see if it is consistent and blocked.

5. There is also a situation that the floor heating construction unit does not fully consider the situation of your house, resulting in some radiators are close to the water separator, and some rooms are too far, the pipe length and number of turns used by each radiator are different when the pipeline is arranged, resulting in an imbalance in water supply, when the water flow is not large enough, most of the hot water circulates through the nearest radiator (professional term "water short circuit"), and the radiator at the far end is actually in a state of lack of water or no water.

Solution: Unplug the return pipes of all branches at the water separator, and open the main water inlet valve to see if the water outlet of each channel is consistent. On the premise of confirming that the water supply flow is normal, close the small inlet branch valve from near and far.

Artificially adjust the amount of water in each way. (It is impossible to re-lay underfloor heating pipes with too expensive rights and interests).

6. If other residents in this unit use radiators, only your home will be changed to floor heating. Because the underfloor heating has a small pipe diameter and is serpentine coiled in the floor, each turn increases the pressure loss by kilograms (the technical term "pipe loss"). In this way, your home becomes the most resistant household, and the hot water will choose to satisfy other users and still be wealthy before it enters your system.

7. If the above methods are invalid after elimination, it is necessary to consider that the pressure and flow of the main heating pipeline of the district heating are abnormal.

The feed water temperature is too low, and all the heat of the hot water is evaporated in advance.

This pipeline distance is too long.

If there is a valve in each branch, you can open this road to a larger one, and the other roads to a smaller one. Let the traffic of this road be larger, and it should be more balanced.

It doesn't matter if the return pipe is not hot, as long as the radiator is hot, it is normal.

If the geothermal return pipe is not hot, it means that there is air or blockage in the return pipe. In this case, we have to find someone to clean the geothermal pipes. There's no other way, because it's all sealed.

Hello dear! It's a pleasure to serve you. What should I do if the floor heating pressure is not enough and the return pipe is not hot?

Reason analysis: the return water pressure of floor heating is insufficient, but the water supply pressure meets the requirements, in fact, the reason at this time is very simple, that is, the water can not pass through the normal circulation of the pipeline. And the most common reason is the blockage inside the pipe.

That is to say, the inside of our heating pipes is clogged due to perennial use or the entry of impurities, which affects the water pressure. Solution: When we find that the pressure of the return pipe of the floor heating is insufficient, the first thing we think of at this time is to clean the floor heating.

For example, the most commonly used method of doing a howl cover is to take the method of releasing water to solve the problem. When discharging water, it is necessary to discharge water to each circuit of ground heating, one circuit after another, so as to ensure that each circuit is cleaned. If the water discharge still can not be solved, then the second method is to take the cleaning of floor heating, and the cleaning should take a special pulse equipment Yulukuan, so that all the impurities in the pipeline can be cleaned.

For example, the floor heating in our home is recommended to be cleaned once after four or five years of use. I hope mine can help you, please help me like it, I wish you a happy life.

The floor heating return pipe is not hot, and the water is not good all the time. It is recommended to close the inlet pipe valve, remove the return pipe, and then open the inlet valve to release the water. The heating water discharge should be "exhaust", that is, the gas present in the pipe is discharged to prevent the gas from causing "gas blockage" and affecting the normal hot water circulation.

In the position of the main water distribution valve of floor heating, there is a special exhaust valve, and different types of exhaust gas are different, and the gas can be released until the water is discharged. <
