Floor heating water separator is a shunt device that divides the hot water or steam sent from the main heating pipe into several sub-pipes to each room. It is an indispensable equipment for floor radiant heating.To a certain extent, floor heating The water heater determines the service life of the floor heating. In order to achieve a good floor heating system circulation, the correct method of using the floor heating manifold is very important for the entire floor radiant heating system.From the three aspects of heating early, middle and end period, we will analyze how to use the floor heating manifold for you.

Circulate hot water for the first time

In the first operation, hot water should be gradually injected and the geothermal heating should be started for the first time. When the hot water is supplied, first open the water divider water supply main loop valve, and gradually increase the temperature of the hot water and inject it into the pipeline to circulate. Check whether there is any abnormality in the manifold interface, and gradually open the branch valves of the manifold. If there is leakage in the water separator and pipeline, the main water supply valve should be closed in time and the developer or geothermal company should be contacted in time.

Air release method for the first time

In the first operation of the geothermal energy, the pressure and water resistance in the pipelines are likely to cause air locks, resulting in non-circulation of the supply and return water and unequal temperatures, and exhaust should be carried out one by one. As shown in the figure below, the method is: close the total return valve for heating and each loop adjustment, first open a regulating valve on the manifold, and then open the exhaust valve on the backwater bar of the manifold to discharge water and exhaust. After the air is cleaned, close this valve and open the next valve at the same time. By analogy, after each air is exhausted, the valve is opened, and the system is officially running.

Clean the filter if the outlet pipe is not hot

A filter is installed in front of each water separator. When there are too many magazines in the water, the filter should be cleaned in time. When there are too many magazines in the filter, the outlet pipe will not be hot, and the floor heating will not be hot. Generally, the filter should be cleaned once a year. The method is: close all the valves on the water separator, use an adjustable wrench to open the filter end cap counterclockwise, take out the filter for cleaning, and put it back in the original after cleaning. Open the valve and the geothermal system can work normally. If the indoor temperature is lower than 1°C without heating in winter, it is recommended that the user should drain the water in the geothermal coil to prevent freezing and cracking of the pipe.

Release all the water after heating

After the geothermal heating period ends each year, all the filtered pipe water in the geothermal network should be discharged. Because the boiler pipe water contains a lot of tiny particles such as slime, impurities, rust and slag, the water quality is turbid, and the inner diameter of the geothermal pipe network is very fine, and the precipitation of calcium, magnesium, salt and other substances contained in the water will generate hard scale and coat the geothermal heat. On the inner wall of the pipe network, the bends are more serious, and they cannot be washed away even by pressurized water flow. This is also the reason why the floor heating needs to be cleaned.

Using skills

1. The water separator can control the heating temperature of each room or area by way, and the user can adjust the temperature of the room according to their own needs; The heating temperature of the pipeline.

2. There is a filter on the front end of the water separator. The user will remove the filter at the bottom of the filter for cleaning and install it regularly or irregularly during the annual heating period to ensure the cleanliness of the water pipe. After heating, the pipe network should be flushed with clean water.

3. At the beginning of heating, the internal temperature will not be felt immediately. During this period, the indoor ground concrete layer is gradually being heated to store thermal energy. After 2-4 days, it can reach the design temperature. For example, the user’s own heating water temperature should not exceed 65°C.

4. If you are not at home for a long time, you can use the main valve of the water separator to reduce the circulating water volume, and never close it all. If the room is not heated throughout the winter, the water in the pipe should be blown out.

As a system project, floor heating and air conditioning are both subordinate to high-power electrical appliances, and both have their own service life. If consumers use improper methods and poor maintenance methods, they are likely to die during use. As the heart of the underfloor heating system, how to use the underfloor heating water separator and mastering a certain method of using the underfloor heating water separator can help us better use the floor heating, which not only saves money and energy for us, but also achieves a better and safer home heating effect.
