Radiators not hot? 100, radiators not hot?

It is possible that the reason for the small water pipe is that the water circulation is slow and the heating is not hot, the first group of heat is the front end of the water inlet and the second group of heat at the end will definitely be lower, you can change the pipe to a thicker point to accelerate the water flow and increase the heat.

It should be changed to a series connection, the parallel flow of water will flow from the nearest pipe, and it is not conducive to exhausting air, the drain valve should be opened until the hot water is out and then closed.

The main reasons for the incomplete heating of the heat sink are: 1. The heating temperature and pressure are too low; 2. Gas blockage, that is, the water speed and water pressure are too high when the water is filled with water at the time of initial irrigation, and the gas in the pipeline is mixed into the water, and the exhaust port at the end needs to be opened to add water slowly; 3. Impurities (substances) are mixed in the pipeline, or too much scale accumulation of the old heat sink flakes, resulting in poor water flow; 4. If it is installed by non-professionals, a similar situation will occur, that is, the installed pipeline does not have a certain slope to cause air blockage.

Recently, the temperature has dropped sharply, the use of radiator heating users have increased a lot, many families enjoy the efficient heating of radiators at the same time, there are also some family radiators are not hot, generally the radiators are not hot above and below, in recent days, the Comfort 100 Engineering Department has received a lot of such consultations, for this reason, Comfort 100 statistics on some radiators are not hot above and below the reasons why they are not hot, and give a comprehensive solution for everyone.

The radiator is hot above and not hot below: the temperature difference, if the upper supply and lower return system, the temperature difference between the inlet and outlet of each layer of radiator should not exceed the degree (infrared thermometer can be used to measure the temperature), if this value is exceeded, it can generally be judged that the riser circuit has a small circulating flow and vertical misalignment;

The radiator is hot above and not hot belowThe solution: remove the radiator, connect the two leather pipes to the window, open the inlet valve, flush the inlet pipeline, if the pressure is sufficient (the amount of water is large), it means that there is no problem with the inlet pipeline, then close the gold water valve; If the pressure is insufficient, find out if there is a blockage inside the upstream pipeline;

The radiator is hot above and not hot below: if necessary, open the skylight of the upstream pipeline to check, generally there will be waste plastics, insulation foam materials, etc., and remove them;

The radiator is hot above and not hot below: rinse the dirt accumulated in the removed radiator;

The radiator is hot above and not hot below: open the downstream valve and carry out backflushing, the method is the same as above;

The radiator is hot above and not hot below: connect the radiator, if the temperature difference returns to normal, the heating is not hot The problem is solved;

The solution to the problem that the radiator is hot above and not hot below: the serious water loss of the system is also a major reason why the heating is not hot, and the heat loss and economic loss are quite amazing;

The radiator is hot above and not hot below: if it is not solved, check whether the valve of the riser is opened correctly.

The radiator is hot above and not hot below: if the whole building is not hot, check that the pressure difference between the water supply and return should be greater than; Otherwise, it is caused by the hydraulic imbalance of the heat network, and the heat network should be adjusted, or a small circulating water pump should be installed at an appropriate position to solve the problem.

In fact, it is not a big deal that the radiator is hot above and not hot below, and the general user can solve it by himself, of course, if there is a professional technical problem, you should ask a professional radiator expert or installation company to solve it.

Solution 1 of the heating is not hot: Check whether the water inlet filter is unobstructed; The inlet pipe is hot, the return pipe is not very hot, the radiator is warm, and the exhaust valve is always released with warm water. At this time, the filter at the inlet valve should be checked to see if it is blocked, and if it is blocked, rinsing the filter with a brush and clean water can solve the problem. The solution to the heating is not hot: check whether the pipeline exhaust system is working properly; Especially for first-time or newly retrofitted users, the first thing to check is whether the exhaust valve installed at the high point of the pipe and the top of the radiator drains the air in the system.

Solution 3 of the heating is not hot: Check whether the system pressure is large enough; If the temperature difference between the front and rear groups of the radiator is too large, the experts of Comfort 100 Network suggest that the system pressure meets the requirements under the condition of excluding non-gas accumulation and blockage, and if the pressure does not meet the requirements, it is necessary to consider pressurization. The solution to the heating is not hot: check whether the hot water in the system is "approaching"; For users with parallel branches of indoor radiators, if the existing branch radiators are hot and some branch radiators are not hot, most of them are caused by hot water "approaching the road". In this case, the inlet or return valve of the proximal radiator should be closed appropriately, so that more hot water can be supplied to the distal radiator.

1. Confirm whether the valve is open.

If the heating valve is closed, open the heating valve as shown below

Angle valve valve. Counterclockwise is to open the valve. Clockwise is the valve off.

2. Check if the other heaters are hot.

If other heaters in the house are hot, it means that there is no problem with the temperature of the heating water, which is a circulation problem, and the water circulation is not good. If it is a sub-household heating in central heating, check whether the filter on the water supply pipe in the home pipe well is blocked. I don't have the tools for this, so I need to find a heating company to check it.

3. Confirm the heating pipeline connection method.

For example, if one group of the two-pipe parallel heater is not hot, and the other groups are hot, turn off the inlet and return valves of the front heater accordingly. Drain the heating hot water backwards. Then check if the heating is hot.

If it is a single pipe in series, the front heating is hot, it is recommended to add a circulating pump, the purpose is to make the water circulation faster.

If it is a single pipe of iron pipes, the first thing to touch is whether the pipe coming down from the upper floor is hot. If the pipe is hot, the heating body is not hot, take the deflation method, use the word change cone to twist the deflation knob screw, let the gas inside discharge until there is water flowing out continuously, and the heating can be heated. If the inlet pipe is not hot, contact the heating company.

4. How to deflate the heater.

Close the inlet and return valves, open the air screws until the water continues to flow out, close the air screws, open the water inlet valve, and open the air screws until the water continues to flow out. Close the air screws and open the return valve. Then open the air screw until the water continues to flow out.

A complete deflation process ends.

The reasons and solutions for the radiator not to heat are as follows:

1. Whether the valve of the radiator is open.

1. Whether the two locking valves and two ball valves have been opened.

2. Whether the indoor heating facilities are covered or not affects the heat dissipation effect of the radiator.

3. Whether the filter at the entrance valve is blocked.

4. Whether the indoor radiators and pipes are exhausted one by one.

When the radiator is not hot:

Find out which heating unit supplies heat, and in principle, who supplies and who manages. Report to the relevant units of the construction of the building, and they will be responsible for handling it. If the pipeline in the community is in disrepair or out of balance, it should be repaired and adjusted by the property rights unit.

The six main reasons why household radiators are not hot zxjsljf321@

Now the radiator is not hot.

It has a lot to do with the choice of location layout of the installation, and the radiator is not hot for the following reasons:

Clause. First, the simplest one is to close the valve, as long as the valve is opened, this is the most common.

Clause. Second, the air in the radiator is not released, blocking the flow of water, so that the radiator can not dissipate heat, this is also simple. Deflation through the exhaust valve or running air.

Clause. Third, the kind of radiator pipe walking method goes in and out, the radiator is only hot at the bottom, and not hot at the top. It is caused by several possibilities: 1 is that the installation of the radiator is down, that is, the radiator is installed on the top with a water retainer, and the bottom becomes straight, and the hot water is all gone away from below, because there is a water retainer on the top and the water flow cannot be exchanged, resulting in the radiator not being hot, and there are also half of the radiators that are not hot, half of which is hot.

It is also caused by the water retaining sheet. 2. There is no water sheet, the water pressure is too large, the cold water and hot water barrier are broken, and the cold water above cannot flow down. Such a situation is rare, as long as the water inlet valve is turned off a small point, there should be no problem without adding a water shield below, but the heat dissipation is less than the original.

3. It is caused by too much air on it.

The location and layout of the heating installation determine the heat of the radiator.

Clause. Fourth, all the radiators in the home are hot in the front, but not in the back? This will happen if the pipe layout of your home is a single pipe in series, as long as the group radiator is turned off, the rest will not be hot. If the inlet water temperature is 75 degrees, after passing through the first group of outlets, it will become 65 degrees or 55 degrees and then enter the second group, and the second group of outlet water temperature will become between 55 degrees and 35 degrees, and in the end it will definitely become that the radiator is not hot.

The best way to solve this situation is to re-run the pipeline, and the second is to add a circulating pump. There's nothing else to do. Most of the stupid people are doing this.

Clause. Fifth, the radiator in the parallel pipeline is not hot and the heat is uneven, mainly because the valve is not adjusted well, and the pipe is not thick enough, and the radiator will not be hot if it does not meet the standard, and the general 100 square room below the room needs 6 points of pipe, but the minimum water flow rate should reach h 49 kg. 100 to 180 bungalows need 1 inch of pipes, this pipe walking method is beneficial, that is, you can adjust the temperature of that set of radiators and the temperature of the room at will. At the beginning, the plumber asked to adjust it.

And the worst one is to make the inner wall of the pipeline smaller or blocked during construction, and it will not be hot, which is not solved.

Clause. Sixth, the radiator goes up and down, it is definitely not hot, unless it is steam, and the pipe and the radiator standpipe are vertical, there may be hot spots, if not hot, the principle of not hot is the effect of automatic convection of hot water and cold water.

The hot water always rises on its own, and the cold water sinks automatically, so the radiator is not hot. The solution is to change the pipes to go up in and down out, or down in and out of the pipe.

It could be heating.

Come inside to foul, self or not exhaust the cool air in time.

1. Heating facilities have a life span.

The service life of the radiator in the pipe network is 8 years, and the user will cause serious internal corrosion, scaling and blockage due to failure to repair and maintain it on time, which will affect the heat dissipation effect. Therefore, the user should request the property or professional to flush or replace the heating facilities in time before operation.

2. If the radiator is not hot, it should be considered to release water, but it is actually deflated.

The air bubbles in the radiator and radiator tube are very strong"Air resistance"Function. The drain switch is in a bolt above the side of the radiator (this bolt is separated from the thermostat knob on either side of the heater, and there is a white plastic part on the bolt). Before discharging water, you need to rotate the white plastic parts on the water discharge switch, and align the water discharge holes on the plastic parts with the water basin (hold the basin first, spray it stable and then put it down, not tired), and then use it"one"The zigzag cone rotates the small metal screw in the center of the plastic part counterclockwise.

3. Special treatment is required for tenacious radiators.

The heating that is still not hot after a large amount of water is discharged is generally on the side branch of the heating pipeline circulation, that is, the radiator is not on the bus of the heating circulation. The hot water of the radiator always flows on the main line, and does not flow to the heating through the side branches, so the heating never has hot water flowing, and the bubbles in the corresponding underground heating pipe cannot be discharged.

What should I do if the radiator is not hot? Look at how the plumber exhausts, and it will work immediately, and the radiator is not hot again? A small trick of the plumber, the temperature in the house rises immediately, and it does not cost a penny.

I guess that the heating in your study is the end of the pipe, and the water flowing to the heating in the study cannot overcome the resistance of the heating itself, so the hot water cannot enter the heating.

It may be that during the heating pressure test, the impurities in the pipe blocked part of the pipe, causing the water to flow poorly, although you can release the water, but its pressure and flow are not enough, because my family has had similar problems before.

Common faults.

1: The heating is not hot overall. Exclusion method: Open the inlet and return valves.

Common fault 2: The heating does not heat up.

Exclusion method: There may be gas in the heater, and it needs to be deflated.

Method 1: Close the water inlet valve first, open the air bleed valve to exhaust, and close the air release valve when there is water overflow.

Method 2: Close the water inlet valve 3 4, then close the return valve, release the valve to exhaust, close the air release valve when there is water overflow, and finally open the return valve and the water inlet valve.

Exclusion method: low inlet water temperature, increase inlet water temperature.

There is no heating water inlet and outlet connection.

That's because of the heating station.

The outlet pipe is blocked, the water does not flow, so it is not hot, and your second method can only rule out that the radiator is not blocked.

What should I do if the radiator is not hot? This is one of the most searched and consulted problems by heating users during the heating period, and it is quite a headache, and it is difficult to solve it completely. Today, the top ten brands of radiators, Rubens radiators, give you a detailed answer to what to do if the heating is not hot?

First of all, let's take a look at the phenomenon that the radiator will not be hot, if it is not hot, you can sit in the right seat.

For example: 1. The user radiator in the whole community is not hot enough;

2. All the radiators in the house are not hot; Some rooms at home have hot radiators, and some are not;

3. For a group of radiators, there are a few hot pieces and a few non-hot ones;

4. A set of radiators is hot at the top but not at the bottom;

5. A set of radiators is not hot on the top and hot on the bottom.

The radiator is not hot and there are probably only these phenomena, below, let's find out the reasons respectively, and then prescribe the right medicine.

Reason analysis: 1. The radiators of the users in the community are not hot enough, and the general reason is that the temperature of the heating is not enough. This requires neighbors to consult and communicate with each other, whether there is no hot phenomenon, to determine that it is not hot, just find the heating unit, and now it has been stipulated that if the indoor temperature of the heating is not up to standard, you can apply for a refund of the heating fee.

2. If all the radiators in your own home are not hot, then you need to check the reason, whether the home heater was hot last year, so as to determine whether there is a problem with the installed pipes, if it was hot last year, it is not hot this year, you can check whether the valve and temperature control valve of the radiator are opened. If it still doesn't work, it should be that the radiator is blocked, and you can find a professional cleaning person to clean it.

3. If the radiator has several groups of hot and several groups are not hot, or check whether the radiator valve is open, this reason is generally that the radiator is collected inside, so it is recommended to release the radiator.

4. The radiator is hot above, not hot below or not hot above, hot below, this should be a bad heating cycle, you can find a professional to test the water inlet pressure and return water pressure, to see if the pressure difference is too much, whether the heating in and out of the water pipe is reversed. If this is the case, the pipes need to be modified.

Therefore, Rubens Radiator summarizes that there are about three reasons why the above radiators are not hot: heat source problems, pipe installation problems (resulting in poor pressure circulation), radiator problems (blockage, insufficient number of pieces, and unadjusted valves). Find the corresponding phenomenon, and then find the cause according to the phenomenon that the radiator is not hot, and finally find a countermeasure to solve it.
