What is the cause of poor water circulation in underfloor heating?

The circulating pump in the cell is not opened, or the pump is too small and the pressure is insufficient. Otherwise, the filter is clogged and needs to be cleaned. However, it is not a good thing that the water is circulating too fast, and the heat is circulated before it is finished.

According to the convention, this should be the reason for the property of the community.

1. Municipal central heating is that the municipal heating pipeline is connected to the community heat exchange station (mainly for the control of heating pressure and temperature), and then transported to each household by the community heat exchange station.

2. The overall circulation and use of community central heating is responsible for the property of the community, so if the circulation is not good, it must be the reason why the district heating is responsible.

The causes and solutions of floor heating not circulating are as follows:

1. Check whether the main valve is open.

If the home is central heating, first check whether the heating valve of the main pipeline is open, if the heating valve of the main pipeline is closed, find the property to open the valve, and then observe whether the water pressure is normal. Repair in time when problems are found.

2. a water separator.

Whether the switch of each branch is turned on.

Then check whether the water supply valve and return valve of each branch of the water separator are opened normally, if the return valve is not opened, the water flow will not form a circulation, and the floor heating at home will not be hot. The return valve is not fully opened, and the slower water circulation can also affect the heating effect of the home.

3. The pipeline is blocked.

There will be more impurities in the central heating water, after a year of accumulation and precipitation, it is very likely that the floor heating pipe will be blocked, if it can not be dredged in time, it will also cause the phenomenon of floor heating is not hot, there is a possibility, because there is a very thick scale on the wall of the floor heating pipe, which affects the normal heat dissipation effect.

4. There is no deflation before heating.

After the heating starts, there is no normal deflation operation, and there is air pressure formed in the pipeline, and the water flow cannot be refluxed normally, resulting in the floor heating is not hot. At this time, it is necessary to find the exhaust valve, which is just above the water separator branch, and the air in the pipe can be emptied.

5. The backfill is too thick.

New heating users, each branch valve switch is also normal, the floor heating pipe is relatively clean and tidy, the water supply and return water temperature are normal, but the heating temperature can not be reached, it is likely to be because the backfill is too thick when decorating at home, resulting in too slow heat dissipation, can not achieve the expected heating effect, this phenomenon is more troublesome to deal with, rather than reinstalling, it is better to install a group of radiators.

Be. In home heating, the water in the floor heating and radiator system is closed circulating water, which is the softened water that has been treated with anti-corrosion treatment in advance, and the floor heating is the abbreviation of floor radiant heating, which is to use the whole ground as a radiator, through the heat medium in the floor radiation layer, evenly heat the entire ground, and heat supply to the room through the ground in the form of radiation and convection heat transfer to achieve the purpose of comfortable heating. <

According to different heat transfer media, it is divided into two categories: water floor heating and electric floor heating, and according to different pavement structures, it is mainly divided into dry floor heating and wet floor heating.

Water floor heating refers to a heating method that heats water to a certain temperature and transports it to the water pipe cooling network under the floor to achieve the purpose of heating through floor heating. The low-temperature floor heat medium forms a gradually decreasing temperature gradient from the soles of the feet to the head indoors, thus giving people the comfort of warm feet and cool heads. Radiant ground heating is in line with the fitness theory of traditional Chinese medicine "warm feet and cool feet", which is the most comfortable heating method and a symbol of modern quality of life.

It is divided into two categories: water floor heating and electric floor heating from the thermal medium quality, and is divided into wet floor heating and dry floor heating from the pavement structure. From the surface decoration material, it is divided into floor type floor heating and floor tile type floor heating; Functionally, it is divided into ordinary floor heating and far-infrared floor heating.

If the floor heating is not circulating, first of all, you need to check whether the main valve of the floor heating is open and whether the sub-valves of each room are opened, if it is opened, you also need to pay attention to whether the gas in the pipeline is exhausted before use, sometimes it is due to the air in the pipe that causes the pipe to be blocked and not circulated, of course, the final need to check whether there is water or whether the water pressure is enough at the water inlet of the floor heating.

The underfloor heating circulation pump is a underfloor heating circulation system.

The most important components. Most of the reasons why the floor heating does not circulate are because the floor heating circulation pump is malfunctioning. The solution to the non-circulating floor heating is to disassemble the circulating pump in the floor heating system, check out the faults of the circulating pump, and repair it if there is a small fault.

If not, you can replace it directly.

How to solve the problem?

We are collective heating.

Answer: Open each valve of the inlet valve and each valve of the return valve, put a small plastic pipe on the inlet and exhaust valve, exhaust until there is no bubble at all, and then open the return exhaust valve to exhaust until the water is hot.

Ask a question, then I'll give it a try.

Heating is up and down the back type, that is, heating from the top to the bottom, it is best to check the water inlet and outlet of your home, whether there is a blockage, and there is an air blockage, generally there is an exhaust valve at the inlet pipe of the floor heating, and the air is deflated until there is a water flow. There is no problem of insufficient pressure, and the height difference pressure of the floor itself is enough. That is, the floor heating circulation pipe in your house is blocked, so troublesome.

Let's figure out how to unblock it yourself.

It should be the underground pipe of floor heating that needs to be cleaned, for a long time, it produces scale, which affects the heating, cleaning, it is very simple, find a professional floor heating installation company, let them come to the service, you can (floor heating pipe cleaning is necessary to add a special pipe cleaning liquid, the cleaning liquid used by irregular companies has a great corrosive effect on the floor heating pipes), I hope it will help you.

See you mentioned that it was only installed last year? If you understand correctly, is your home installed with traditional underfloor heating? Is it the kind of cement and bean stone layer that is backfilled with a thickness of several centimeters after coiling (different companies have different backfill thicknesses and different costs)?

If it is, and if it's not hot for the first year, the problem shouldn't be that the pipes are dirty! If it is not hot locally, it is a pipeline problem caused by the coil, one is that the length of the floor heating pipe is too different, the other is that the floor heating pipe is broken in some places when the coil, resulting in excessive water resistance, and whether the manifold is not opened; You mentioned that you have installed a circulating pump, is it possible to heat it up after installation? If yes, it's a matter of water resistance.

In the future, it is better to install floor heating, or buy electric floor heating, there is no later matter, and cost.

You can go to the underfloor heating network to see, there are a lot of professional underfloor heating knowledge on it, which should be helpful to you.

2. The overall circulation and use of heating in the community is responsible for the property of the community, so if the circulation is not good, it must be the reason why the district heating is responsible.

Possible reasons are: the heating valve is not opened, the floor heating water divider.

Whether there is a gas collection phenomenon, and whether there is a gas collection phenomenon in the floor heating water divider.

Solution: 1. The heating valve is not opened. Confirm that the heating valve in the pipe well in the corridor is open, and if not, it should be swiped with a heating card.

2. Whether there is a gas collection phenomenon in the floor heating water separator. If there is a gas trapping phenomenon, it is necessary to vent it.

3. Whether the filter screen of the water separator is blocked by impurities. If there is a blockage, it needs to be cleaned up in time. Slow Close.

4. Whether there is a gas collection phenomenon in the floor heating water separator. If it is not the general case of the whole building, this possibility is very high.

5. If it is still impossible to solve it or it is a common situation, you need to call the customer service staff of the heating company and ask them to deal with the problem of no heat in the community, and make corresponding treatment for this situation.
