Is it used for floor heating? Do you need to deflate before underfloor heating

1, as shown in the figure, the general situation is that the upper row is the water inlet valve, the lower row is the water outlet valve, here we can ignore the water outlet valve because there is no single pipe outlet valve at all, now we only need to control 1234567 these valves can complete the water discharge operation, and each step of the operation in the future has been subject to the following figure.

2, put all the way to put, close the valve, close the valve 7, connect the appropriate pipe on the drain valve 2 (some have a faucet here) along the sewer, open the drain valve 2 or the faucet at this time, so that the water released is in the pipe 1, until the clear water is released.

3. Put the second way, close the valve 1 just now, open the valve 2, you can put the water of the pipe 2, and the next few roads can be put into the clear water to complete the water discharge.

4. After draining the water of each way, the pipeline is basically cleaned up, and the air clamping in the middle is also discharged, and then the valve can be opened, and the air release valve 2 or the faucet is closed.

5. The method of deflation is very simple, open the venting valve separately for deflation until the water flows out. It is recommended to deflate once after draining the water, and then let it out again after an hour or two to see if there is any gas.

You can properly deflate, as soon as there is water out, close it, and then deflate it later, and close it again when the water comes out. Do it repeatedly. Put out the blocked air, and the heating will be warm. But don't be waterproof blindly.

Floor heating needs to be deflated before heating. It can be put on when the heating is started. Underfloor heating tips:

Set the floor heating temperature reasonablySet the floor heating temperature reasonably. Floor heating is a very common way of heating in winter, and the choice of winter heating is a type that saves money and energy.

It is effective in making underfloor heating energy efficient. If the room thermostat is set to 16-18 degrees, and the actual floor heating is 19-21 degrees, if you want to increase it by one degree, you will have to increase the cost by 5%.

Yes, floor heating is vented for better heating, because if there is air in the heating pipe, the hot water will not be smooth when circulating, and the air contains oxygen, which may affect the equipment, so after using the floor heating for a period of time, we need to exhaust the air in the floor heating pipe.

Underfloor heating: is the only equipment we come into contact with and the equipment we need to do the exhaust operation. It is divided into water supply (inlet) pipe and return (outlet) water pipe, generally speaking, the upper side is the water supply pipe, the lower side is the return pipe, each has a valve, ball valve:

The horizontal direction is on, and the vertical direction is off. Gate valve: the screw is closed when screwed clockwise, and the screw is open when screwed counterclockwise.

In addition, a soft skin pipe is required, which is similar in size to the exhaust valve port, has elastic force, and can be tightly clamped on the exhaust valve port to prevent it from popping out during exhaust and affecting hygiene. A basin of water. It is best to make sure that the exhaust is at normal heating.

It is best to exhaust air one by one, in the process of the first operation of geothermal energy, due to the pressure and water resistance in the pipeline, it is easy to produce air locks, resulting in non-circulation of water supply and return, and the temperature is not equal, and exhaust should be carried out one by one.

Close the main return valve and each loop control valve for heating, the main return valve is in front of the water separator, the valve on the pipe below, and the pipe with low temperature is the return pipe. First, open a regulating valve on the water separator, then open the exhaust valve on the water return bar of the water separator to discharge the water and exhaust the air, and then close the valve after the air is discharged, and open the next valve at the same time. And so on, after each air is drained, all the valves are opened, and the system is officially operational.

The number of exhaust gas is directly related to heating, such as running water leakage and the length of heating time, because of the short heating time at the beginning of heating and fast stop heating, the circulating pump and heat exchange station also have a stop time, which is easy to cause air blockage, so we should exhaust more, generally after a thorough exhaust can be. In the later exhaust, there is no need to close the valve, a small amount of air can be directly discharged, and the air blockage mostly appears in users on higher floors, and the top floor is the most common.

In fact, the essential reason for the water release of floor heating is to make the floor heating work more efficiently and achieve a more comfortable heating effect. In daily life, there are three situations that require users to put water for underfloor heating. After the floor heating is used for a long time, there will be air entering the pipes, which will affect the normal circulation of hot water and cause the floor heating to be not hot.

In addition, the oxygen in the air can corrode the metal, so it is necessary to drain water from underfloor heating. And in winter, some users may not use underfloor heating, at this time, the water in the underfloor heating will freeze into ice due to the low temperature, and squeeze the pipeline after expansion, and directly damage the pipeline in serious cases, so if it is not used in winter, the water should be released in time. Finally, when the heating period is over, many users may leave the floor heating alone, or do not release all the water, and there are some small particles in the water remaining in the pipe, which generates a lot of scale attached to the inner wall of the pipe through a series of chemical reactions, causing blockage, affecting the water flow for heating in the coming year, so that the floor heating is not hot.

Floor heating deflation is for better heating, because if there is air in the heating pipe, the hot water will not be smooth when circulating, and the air contains oxygen, which may affect the equipment, so after using the floor heating for a period of time, we need to exhaust the air in the floor heating pipe.

In the operation of floor heating, there will be gas in the floor heating pipes, and these gases will produce gas blockage when they reach the maximum storage value.

When the water for heating comes, the air from all the pipes in the house must be pushed out for normal circulation. Otherwise, it won't be hot.

Open the water valve, see that the pressure gauge is normal within the pressure of 2kg, if it is the first time to heat the exhaust valve exhaust, the exhaust standard is the return pipe until it is hot.

When ventilating underfloor heating, turn off the other sub-pipes first. Close the return valve and prepare a basin. Exhaust is performed by placing the other end of the exhaust pipe in the basin.

Open the upper and lower switches corresponding to the pipe subdivision and open the exhaust valve. The floor heating starts to exhaust, and each branch should be vented separately. It takes about 5 minutes to drain, and the floor heating can be discharged when the return valve becomes hot.

1. When venting the floor heating, close the other sub-pipes first.

2. Close the return valve and prepare a basin.

3. Put the other end of the exhaust pipe in the basin to exhaust.

4. Open the upper and lower switches corresponding to the pipeline, and open the exhaust valve.

5. The floor heating starts to exhaust, and each sub-division should be vented separately. It takes about 5 minutes to drain, and the floor heating can be discharged when the return valve becomes hot.

The details of the floor heating exhaust water discharge ** are as follows:

Prepare materials: water pipes, pliers, etc.

1. Prepare the water pipe and pliers, first find the water discharge position, and then find the air outlet of the water inlet pipe on the water separator. If you touch it with your hands, the hot one is the water inlet pipe, and the cold one is the return pipe.

2. Connect the water pipe to the air release valve of the water inlet pipe of the water separator, and at this time you must pay attention to the fact that someone should take care of it next to you when you are deflating. There is a high chance that the deflating hose will jump. Prepare a towel, wrap around the valve, and open the valve with pliers.

Be sure to do it gently, lest the water run everywhere.

3. Then put back the gas from the water pipe. First close the main valve of the return manifold, the main valve is a green or red long handle, and it will automatically close when rotated 90 degrees. The method is the same as the water inlet above, just connect the pipe to the air release valve of the water diverter return water.

Underfloor heating that has been running for more than 2-3 years requires special attention:

1. Look: The wall of the healthy mobile floor heating surface is free of water droplets and water stains, and it is clean.

2. Screwing: Open the valve by hand, and the healthy floor heating should be opened and closed flexibly and the air release valve smooth.

3. Wrench: When there are people at home, use a wrench regularly to check whether the internal thread cap at the connection between the angle valve and the geothermal pipe is loose, because the pipe fittings are heated by different temperatures during construction, and the pipe fittings are heated differently, and there is a phenomenon of expansion or indentation, which is easy to cause the loosening of the originally well-sealed pipe connection.

The floor heating needs to be deflated, otherwise there will be air resistance, resulting in no internal water flow, so that the floor heating will not circulate water, that is, it will not be hot, the specific operation steps are as follows:

1. Close all valves on the floor heating valve group, the main valve, the branch valve, and the air release valve.

2. Open the main valve of water inlet.

3. Open the return water release valve.

4. Open the first branch valve of the return water.

5. Open the second branch valve when the return water release valve flows out of the clear water without bubbles.

6. Use the same method to open the rest of the branch valve.

7. Finally, when the main valve of the return water is opened, the operation is completed by closing the return water release valve.

Notes:1. Pay attention not to leave people when deflating to prevent too much running water.

2. After the operation, check whether there is water leakage to avoid subsequent failures.

You don't need to deflate it as often, you can put it when you start heating.

Underfloor heating tips:

1. Set the floor heating temperature reasonably.

Setting a reasonable floor heating temperature is effective in making floor heating energy-saving. If the room thermostat is set at 16-18 degrees, the actual feeling of floor heating is 19-21 degrees, if you want to increase one degree, you will have to increase the cost by 5%, so winter heating is not the higher the temperature, the better, a reasonable temperature helps to reduce heating costs and improve human comfort.

2. Do a good job of wall insulation in advance.

If you take into account the need to install floor heating, then you should use double-layer windows or external wall insulation and other strategies to improve the thermal insulation performance of the house, which is the root of solving the problem and reducing the energy consumption difference.

If the air in the floor heating is not clean, you need to close the return valve and open the air release valve at the same time. The part of the main floor heating pipeline connected to the main pipe and the water separator, the main pipeline is generally made of aluminum-plastic composite pipe, which needs to be insulated, because this pipeline often increases the heat loss in transit, which is easy to oxidize the pipeline; In underfloor heating systems with smaller units;

The supervisor uses very little, and the direction is simple. However, in the villa or duplex these relatively large floor heating systems, the supervisor uses a lot of dosage, and a professional designer is needed to design the direction of the supervisor, and the installation requirements of the supervisor are also relatively strict, to be horizontal and vertical.
