What to do if the geothermal heat is overheated Will turning off the valve cause the water pipe to c

Geothermal energy is different from ordinary heating facilities, and many problems should be paid attention to in the use and maintenance, so that the geothermal energy can fully play the heating effect. Wang Zhanyou introduced that after the geothermal installation is completed, when it is started for the first time, the water separator should be half-opened first.

The main loop valve of the water supply allows the hot water to gradually increase the temperature and inject it into the pipeline for circulation. At the same time, check whether the interface of the water separator is abnormal, and open the valves of each branch of the water separator one by one. "When heating for the first time, it is necessary to check the heating pipeline and valve to see if the valve is open, and divide the water collector.

whether there is a temperature in the upper and lower pipes, and check the water supply and return pipes.

Generally speaking, the temperature of the water supply pipe should be higher than the return water temperature 10 15. ”

Wang Zhanyou also recommended some simple ways to solve the incurable diseases of household geothermal energy: when the geothermal heat is too hot to control, you can close the main water inlet valve on the water separator, if the temperature can not be controlled, you can ask the property to open the lock valve in the pipe warehouse a little smaller; If the geothermal heat is not hot, you should check whether the water supply and return valve of the manifold is opened, whether the locking valve in the pipe bin is open, and look at the pressure gauge.

Whether the water supply and return is isobaric, please open the balance valve.

Make adjustments. "By adjusting the balance valve, the heating unit can change the situation of overcooling or overheating. ”

The geothermal heat of individual families is often hot and cool, Wang Zhanyou said that this is because there is gas in the geothermal pipe, resulting in air resistance, and the hot water can not enter, the exhaust valve on the return water pipe should be opened, and the cool water will be released.

Geothermal energy is not as hot as a year, mainly caused by a variety of reasons such as heating water quality, involving after-sales maintenance and geothermal pipeline cleaning and other issues, "geothermal pipe scaling will seriously affect the heating temperature, so geothermal pipes are best flushed regularly, there are three main methods: clean water cleaning, chemical washing, using geothermal pipeline cleaning machine cleaning, the last method is more concise, fast, and the cleaning effect is the most thorough." Wang Zhanyou emphasized that a filter is installed in front of each water separator, and when there are too many impurities in the water, the filter should be cleaned in time.

When there are too many impurities in the filter, it is easy to cause the outlet pipe to be not hot and the ground heat is not hot, so the filter should be cleaned every other year. When cleaning, all valves on the water separator should be closed first, and then the filter end cover should be opened counterclockwise with a live wrench, and the filter screen should be taken out for cleaning. Open the valve again and the geothermal system is working properly.

If the indoor temperature is lower than 0 when the heating is not provided in winter, the user should also put the water in the geothermal coil.

Drain to prevent freezing and cracking of the pipe. ”

At the end of the annual heating period, the user should discharge all the boiler pipe water in the geothermal pipe network. Otherwise, the original sewage impurities in the boiler will remain in the pipe network for more than 7 months, and if not removed after long-term scaling, it will cause a decrease in flow, poor flow and a decrease in thermal radiation value, resulting in pipe network blockage, can not be cleaned, and even cause the entire geothermal pipe network to be scrapped. Wang Zhanyou suggested that those users who pave geothermal should carry out systematic repair and maintenance of geothermal energy before heating every year, and ask a professional construction team to test to ensure normal heating in winter.

Turn off either the hot water inlet valve or the outlet cold water valve a little smaller.

It will not affect, be careful not to half-open and half-close, which will seriously affect the service life of the ball valve.

Dear, I'm glad to answer for you Answer: The water valve of the building is turned off and does not affect the geothermal heat. The water valve at home has nothing to do with floor heating, it does not affect the belching, and the two passages are closed, so turning off the water valve at home does not affect the floor heating.

Does the change of turning off tap water affect floor heating? There is no impact. 1. If it is central heating, as long as the heating station does not stop water, the heating will not stop.

2. Even if the wall-hung boiler for heating at home is stopped, even if the water is stopped, as long as there is water in the heating system, and there is no need to replenish water due to working pressure, then the system and the external water system are also separated, and the water will not be affected. Ground radiant heating is mainly divided into water floor heating and electric floor heating according to the different heating methods, and electric floor heating is divided into heating cable heating and electric heating film heating carbon fiber electric heating. Ground coarse heating is low-temperature hot water ground radiant heating, which is a heating method that uses hot water with a temperature of no more than 60 as the heat medium, circulates in the heating pipe, heats the floor, and heats the room through the ground in the form of radiation (primary) and convection (secondary) heat transfer.

Summary. Hello, glad to answer for you. Kiss, during the heating process, the floor heating inlet pipe at home is completely closed, and the floor heating inlet pipe at home is completely closed, which also forms a state of no heating, and the indoor temperature will drop rapidly and become cold.

If the inlet pipe is closed.

Hello, glad to answer for you. Kiss, during the heating process, the home will be completely closed in the heating process, the home floor heating pipe will be completely closed, and the state of no heating will be formed, and the indoor temperature will quickly drop and become cold. If the inlet pipe is closed.

During the heating period, this operation is not allowed, because it cannot completely disconnect the warm water supply channel, and it will still run water, but it is only a little smaller than opening both valves and reducing the amount of water running. 2. Because the temperature control valve of the first section of the ground is set on the inlet water.

Before the heating was stopped, I turned off the water inlet and outlet valves when there was water in the floor heating, and now it is time to heat, what should I do, and will there be any impact?

It is fine if the valve does not leak during heating.

Isn't there anything to be aware of.

Dear, no precautions It is okay if the valve does not leak during heating.

How to close the water valve of geothermal heat, pro! Hello, very high Ye Liang ruxing for you to answer<> pro-geothermal water valve closing method is as follows: 1. There is a floor heating water separator in the floor heating system, and there is a valve on it to control the switch of floor heating, generally a ball valve, if it is parallel to the pipeline, it indicates that it is open.

If it is perpendicular, it means that it has been closed, and through this valve, we can open and close the song. 2. There are several small valves next to it, which are used to adjust the temperature, the same principle, if it is parallel, it is open, and the vertical direction is closed. Note that the inlet and return valves of the heating should be opened, if they are not opened, there is no way to circulate the water and there is no way to supply heat.

This is because hot water needs to be injected from the inlet valve and then flowed out, creating a water circulation. If the water circulation is not good, the heating effect will be greatly reduced, and the heat will not be generated. 2. Why is the floor heating effect of your home getting worse and worse 1. If the floor heating effect is not as good as a year, it may be that the selected material is an inferior product, the service life will be shortened, the compressive strength will be reduced year by year, and the heating effect will be worse, which will also lead to heat loss and geothermal heating.

2. It is also related to improper construction methods. The so-called 3 points of material, 7 points depend on installation, and the effect depends on the quality of the construction key macro. Choose a powerful and experienced floor heating company for installation, and avoid the impact of human factors on floor heating during the installation process.

3. After the floor heating has been used for a long time, there is gas in the pipe, which will hinder the water circulation and directly affect the heating effect. If you need to open the air valve and empty the air inside until there is hot water, you can improve the water circulation, or if the filter is clogged, you need to clean the filter regularly.

To close the water inlet valve.

1. Put the gas into the water pipe first. Gently open the valve with pliers. Prepare a towel to wrap around the valve, as water will spill out of the valve during deflation and prevent water from running around.

2. Put the gas back into the water pipe. At this time, you need to close the main valve of the return water main first, which is the long handle, which will automatically close when it turns 90 degrees. The deflation process is the same as the water intake.

Put a single water pipe in each house one by one, generally 3-4 per household. The specific operation is to close the main return valve, and close the valves of each single pipe, leaving only one of them to be the return water, and so on for each single pipe.

3. It is to see under what circumstances the gas is successfully deflated, mainly to observe that there is no sewage and gas spraying out of the floor heating pipe. After reaching a basic stable state, finally open all the water flow valves, including the main return pipe, each single pipe. Pay attention to close the two air release valves tightly, with pliers, but not too hard, otherwise it is easy to cause damage to the valve.

When the water inlet valve is closed, the gas cannot be released...

When only the inlet valve is opened but not the return valve, the floor heating pressure is equal to the system pressure. The pressure pressure of floor heating acceptance is times of the working pressure of the system, and the pressure is stabilized for more than 10 minutes without depressurization, and the pressure of the pipe is higher according to the national standard. Therefore, it is impossible for normal working pressure to suffocate the pipe.

Definitely not, floor heating is to use hot water to raise the ground temperature, to achieve the purpose of heating the house, the water in the floor heating pipe will be cold after the heat is transmitted to the ground, the need for new hot water to ensure a steady stream of heat, if you do not open the return valve, cold water can not get out, hot water can not come in even if the inlet valve is opened, so the water in and back water must be opened.

No, but it will cause loosening of pipe fittings due to long-term uneven pressure, which will cause water seepage.

No. Unless the design is not up to standard.

You don't have a thermostat? If you have a thermostat, turn the temperature down. If it is a manual valve, turn the valve on the return end down.

The correct way is to close the small return valve.

Kiss! Hello, glad to answer for you.

The reason why the geothermal water inlet valve is closed when the other wheels are closed is that the water will be released when the water inlet pipe is turned off by floor heating: because there is pressure in the water outlet pipe, the water will flow out.

This is normal. The geothermal pipe is not filled with water, and under normal circumstances, there can be no air in the floor heating, and if there is air in it, it will block the heat transfer and cause the return pipe to not be hot. Close the main valve of the return water collector, then open the main valve switch of the heating pipe, then close the water inlet valve of all branches, open the water inlet valve of each branch respectively, and use the pressure impact to release the gas.

The floor heating filter is installed at the manifold of the floor heating inlet pipe, if the floor heating filter is blocked, a small part of the hot water flow can pass through the floor heating filter, so that the heating temperature of the floor heating will also be reduced, and the return pipe will not be hot, but the temperature of the water inlet pipe is normal.
