Floor heating is hot near and not hot at far, what is the reason for this?

There is a problem with the laying of underfloor heating, the length is not enough or uneven, resulting in an uneven flow of water. Or the distant window is large, the seal is not tight, and the heat dissipation is serious, resulting in the floor heating is not hot.

Underfloor heating is radiant heating, and the heat radiates from the bottom up, which is why underfloor heating is so comfortable. However, if there is a lot of floor covering, it will affect the heat dissipation and may make you feel that the floor heating is not hot. In order to give full play to the heat dissipation effect of floor heating, it is better to choose furniture with feet and not to spread carpets over large areas.

The floor heating is not fully turned on, but only a part of the switch is turned on, resulting in the rest of the house is not hot.

The lack of heating in the home is a problem of insufficient pipe pressure, and you should need to find a heating company or a property to solve these problems. If the circulating power of the floor heating heat source is insufficient, the floor heating return water may not be hot, because the water circulating in the floor heating pipe needs a certain pressure, and the return water will not be hot if the pressure is insufficient. This situation needs to be solved by the heating company or the property.

If the problem cannot be solved, it is recommended to install a circulating pump to improve the circulation of heating water to achieve the ideal heating effect.

1.Close the return valve first, and then manually open the floor heating exhaust valve to exhaust the air. Close the individual valves on the water inlet and keep it open until the exhaust.

There may be water spills during the venting process. You can find a small basin to catch water. Wait until the air in the floor heating ducts is completely drained and heated for half an hour, and you can see the effect.

In many cases, the return pipe is not hot, and it is also related to the exhaust. Use the small valve on the floor heating water distributor to adjust the circulation volume of each circuit to make it circulate evenly and achieve the ideal heating effect. It is recommended that you check the main valves on the underfloor heating main and distribution manifold in turn to see if any of the valves are closed.

If yes, turning them on can fix the problem of the underfloor heating return pipes not getting hot.

2.The pipes of the underfloor heating system are laid under the floor and there is basically no slope. However, after the use of floor heating pipes for a long time, it is inevitable that some scale and sediment will enter.

Once the horizontal pipes of the underfloor heating are reached, deposits are likely to occur. If there is more sedimentation, the water flow will be slower, the heat dissipation will not be good, and the floor heating will not be hot. When the pipes of floor heating are blocked, they must be cleaned in order to restore the original heating effect, and this cleaning of floor heating is not recommended.

It is best to find a professional floor heating cleaner and clean it with professional equipment.

3.Most home underfloor heating is plumbing. When installing this type of plumbing, it is inevitable that there will be some gas in the pipes.

When the gas accumulates to a certain level, it will affect the flow of hot water in the pipes. Of course, stagnant floor heating is not warm. At this time, only the exhaust valve needs to be opened to discharge the gas in the pipe, and the water flow in the floor heating pipe will operate normally, and the temperature will naturally rise.

The above is the problem of whether the floor heating at home is hot? How to solve these problems?

It may be that the floor is too high, there is no plumbing filtration device, the water flow is not smooth, and the floor heating valve is not opened; You should check whether the valve of the floor heating is open, which can effectively discharge the air in the pipe, clean the pipe of the floor heating, buy a special circulating pump, increase the water flow speed, or buy a filter, etc., which can effectively solve these problems.

It may be caused by poor heating, it may be caused by clogged water pipes, it may be caused by the temperature in the water pipes being too low, it may be caused by a lot of water sources, or it may be caused by a lot of rust. It can be solved by cleaning the floor heating.

It may be that the underfloor heating is clogged, or that the underfloor heating is malfunctioning. You can find professional maintenance workers to solve such problems, or understand whether the floor heating is not hot, or you can solve such problems through specific inspections.

1. The floor heating caused by the temperature of the water supply and return water is not hot

The design temperature of the water supply and return of ground heating in most areas is 55 and 45, that is to say, the temperature of the water supply is 55, the temperature of the return water is 45, and there is a temperature difference of 10 degrees between the water supply and the water supply chain; We can buy a thermometer to measure the water supply pipe and return pipe of the water collector at home to see what the temperature of the water supply and the temperature of the return water are; If it is found that the temperature of the water supply and return from the shed is very different from the design requirements, then the central heating company will go to the heating company to solve the problem for us, and the water temperature needs to be adjusted by yourself.

2.The underfloor heating is not hot due to the problem of the difference in water supply and return pressure:

Many people will ignore the problem of the pressure difference between the supply and return water of floor heating, and only care about the pressure of supply and return water, because floor heating relies on the circulation of the two pipes of the water supply pipe and the return pipe to achieve heating, if there is no pressure difference between the water supply pipe and the return pipe, it is equivalent to the water is not circulating in the pipeline, which will lead to the lack of heat of the floor heating.

The pressure difference between the normal underfloor heating water supply and the return water is about the same, that is to say, if we measure the pressure on the water supply pipe and the return pipe of the manifold, the measured result is that the pressure of the water supply pipe is about the same as that of the return pipe; The solution to the insufficient pressure difference between the supply and return water: if it is a self-burning floor heating, then we can install a differential pressure valve on the pipeline to adjust the pressure difference between the supply and return water; If it is central heating, then we have to find a heating company to solve it for us.

3.Underfloor heating due to insufficient water flow in the supply and return water:

This problem is also the most common and easy to solve, the reasons for the insufficient flow of water supply and return are basically caused by pipeline blockage, including the blockage of floor heating pipes, filter blockage, etc.; The solution to the lack of water flow of water supply and return water to cause the floor heating is not hot: in fact, we all know this, that is, to clean the floor heating pipes, we can find professional floor heating cleaning personnel to clean, or we can buy a set of floor heating cleaning tools to clean by ourselves; Also, let's not forget to clean the filters in the tube wells as well as the filters at home.

The valve is broken. Replace the valve with a new one.

There are loop control valves on the water supply pipe and return pipe of the floor heating manifold, if the loop control valve is bad, looking at the valve is in the open state, in fact it is indeed closed or semi-closed, it will cause the coil pipe of the circuit of the floor heating to be not hot;

Because it is very troublesome to replace the loop control valve on this manifold, it is necessary to replace the entire water distribution rod, so first confirm the quality of the valve by discharging water; Close all the valves on the manifold, open the ball valve of the open water, and then open the water supply and return valves of the circuit that is not hot, observe the water outlet, if the water is out, the valve is not problematic, if the water is not out or the water is very small, it means that the valve may have a problem; After confirmation, you can replace the manifold manifold.

Some parts of the heating system are hot, and some places are not hot, which may be caused by static imbalance!

See if it is not hot locally, or a certain room as a whole, if it is partial, there should be impurities inside, but it is not blocked, and the water flow is small. The whole room is blocked

The pipes need to be cleaned, and after a long time, they must be cleaned because there is a build-up of rust, which will also cause it to be not hot.

It may be that the water pressure of the underfloor heating is insufficient, and it may be caused by the air in the pipes.

Add air in the floor heating pipe, which will cause the return pipe to be not hot, the solution is to open the air valve to discharge the air until the water comes out, it is also recommended to ask an experienced master to come to operate.

There is an exhaust valve at the position of the floor heating water divider, turn on the open water to accelerate the heating circulation to remove the air, you must remember to prepare a basin or a bucket to receive water, otherwise there will be a lot of people who flow out and soak the room.

It should be that the heating water pipe of the geothermal is blocked, or there is a problem with the water separator that controls the flow of hot water in the geothermal pipe, it is recommended that you find a professional to find the reason for you, do not do it yourself, I hope you will adopt it.

You can try closing the return valve first, and then manually opening the exhaust valve of the underfloor heating to vent the air, closing each valve on the inlet water first, and then opening the exhaust all the way. There may be water overflow during the exhaust process, you can find a small basin to connect the water, wait for the air in the floor heating pipeline to be completely drained and heated for half an hour to see the effect, many times the return pipe is not hot is also related to the exhaust.

In addition to eliminating the problem of loose pipe laying, I will tell you a complete solution, which we often encounter in the maintenance of geothermal energy.

Close the return main valve and all return branch valves, then open one of the return branch valves, and exhaust on the return water, that is, the water collector, until the water is discharged. Then close the branch valve and exhaust valve. Do it sequentially. Finally, open all return manifold valves.

Wash the inlet filter. The method is to close the main inlet valve, disassemble the filter, there is a small amount of water in it, and connect it with a basin.

This is all done thoroughly, and your problem is solved.

It may be that the floor heating is not evenly distributed.

What to do if the floor heating is not hot - the temperature rises slowly if it is not used for a long time.

Floor heating is a heating method installed underground, and the rise of temperature requires a certain process, and many people mistake this heating process for that floor heating is not hot.

Solution: during the initial heating, the hot water heating should be gentle, the water supply temperature should be controlled at about 10 higher than the ambient temperature at that time, and should not be higher than 32, strictly control the mobile floor heating water supply temperature, set the water supply temperature at 25 to 30, run for 48 hours, and then every 24 hours, raise 3 water temperature, until the design water supply temperature is reached, at this temperature, the floor heating pipe connected to the water collector should be adjusted one by one, until the design requirements are reached, or the indoor temperature is reached.

What to do if the underfloor heating is not hot - the filter or underfloor heating pipe is clogged.

If the main water supply bar is not hot, it may be that the heating water quality is too dirty, which causes the filter to be clogged and cannot be circulated normally. Long-term use of floor heating pipes will generate scale, and the floor heating pipes will be blocked when scale increases, affecting the overall heat dissipation.

Solution: Use a wrench to open the filter, clean the filter inside, and install it back from the new one, or you can find a professional person to clean it. If the pipe is clogged, it needs to be specially cleaned.

What to do if the underfloor heating is not hot - there is gas in the pipes.

If the main floor heating bar is hot and the return bar is not hot, it may be that the air in the floor heating pipe causes air resistance, resulting in hot water not being able to enter the circuit and cannot be circulated.

Solution: Check whether the lower return valve is open or not (a "shape" is open, and a "ten" shape is closed); If there is air in the geothermal pipe to cause air resistance, you can open the air valve to exhaust until the hot water is released, or use the small valve on the water separator to mediate the circulation of each circuit, so that it can circulate evenly and achieve the ideal heating effect.

What to do if the underfloor heating is not hot - the pressure in the pipes is not enough.

The owner's floor is too high or the heating end of the community is not enough, and the pipe pressure is not enough, which also leads to unsatisfactory heating, solution: in this case, you need to find a heating company or find a property to solve, if you can't solve it, it is recommended to install a circulating pump to improve the circulation of hot water to achieve the ideal heating effect.

What to do if the floor heating is not hot - improper construction.

During the installation of floor heating, some construction personnel do not follow the drawings in order to save floor heating pipes, expand the spacing of the pipes when the floor heating coil, or the floor laid above the pipe is too thick, which will affect the heat dissipation efficiency of floor heating.

Solution: It is relatively troublesome to deal with this phenomenon, and it is necessary to re-pave the floor heating pipes, or reduce the thickness of the floor, wasting time and causing greater economic losses.

What to do if the floor heating is not hot - improper use by the user.

In order to make the overall style of the family look more upscale, many users will lay carpets and other decorations on the ground, and the floor heating radiates heat dissipation, and the heat is dissipated from the bottom up.

Summary. Hello dear, Floor heating is installed, but some rooms are hot, and some rooms are not hot at all, it may be that the whole circuit is blocked, which will affect the circulation, which will naturally cause the indoor room to be hot, and some are not hot. There is also a possibility that there is a problem with the laying of coils in the circuit, which is directly related to the laying process.

Or something in the floor heating coil is blocked, which will cause the coil to not be hot, and the corresponding room temperature will not rise.

Hello dear, Floor heating is installed, but some rooms are hot, and some rooms are not hot at all, it may be that the whole circuit is blocked, which will affect the circulation, which will naturally cause the indoor room to be hot, and some are not hot. There is also a possibility that there is a problem with the laying of coils in the circuit, which is directly related to the laying process. Or something in the floor heating coil is blocked, which will cause the coil to not be hot, and the corresponding room temperature will not rise.

First of all, it may be that the circuit valve is broken, resulting in the circuit pipe not being hot, and it is recommended to replace the circuit valve or water distribution rod; Secondly, it may be that the floor heating pipe is blocked, if there are debris in the pipe and the hot water circulation is not smooth, it is recommended to flush the floor heating pipe; Finally, it may be that the floor heating pipe is unreasonable, such as excessive spacing or bending, resulting in the loop pipe not being hot.

Therefore, it is not normal for floor heating to be hot in some places and not hot in some places.
