In the floor heating system, the water collector and the water collector are collectively referred to as the floor heating water separator, which refers to the device used to connect the main heating water supply pipe and the return water pipe in the floor heating system. Its main functions are boosting, decompression, voltage regulation, and diversion. Floor heating water dividers generally use pure copper and stainless steel, so what is the most reasonable way for floor heating water dividers? How to choose a floor heating water divider? How to install the floor heating water divider? Below I will give you a detailed introduction to the relevant content of the floor heating water divider. What is a floor heating water divider
The floor heating water divider is composed of two parts: water separation and water collection, which are collectively referred to as floor heating water dividers. The water distributor is a water distribution device used to connect various heating pipes and water supply pipes in the water system. The water collector is a water collecting device used to connect the return pipes of various heating pipes in the water system. The main accessories of the floor heating water divider are water divider, water collector, inner section head, filter, lock valve, joint head, valve, exhaust valve, heat energy meter.
The working principle of the floor heating water separator
The floor heating water separator is the control center of the whole floor heating system. After entering the room, it enters the main bar of the floor heating water separator after passing through the multi-function filter. In this link, the filter filters out the impurities in the heating medium to prevent the impurities from entering the underground pipe network and blocking the pipeline. The main bar is installed horizontally, so that the heat medium is evenly distributed to the floor heating branch pipes by using the principle of the same height and equal pressure. After the heat exchange system, each branch pipe flows back to the main bar of the water collector, and then flows into the water return port. in the heating system. In addition, a floor heating water mixing device is added to the heating system, that is to say, after the heat exchange, the temperature of the heat medium (water) is still very high. while saving energy.
Types of floor heating water distributors
1. Basic type
It consists of water distribution main pipes and water collection main pipes. A ball valve is installed on each branch port of the sub-collection main pipe, and a manual exhaust valve is installed on the sub-collection main pipe. The basic diverter does not have a flow adjustment function.
2. Standard type
The structure of the standard type water collector is the same as the basic type, except that the ball valve on each main pipe is replaced by a flow control valve. replace. Replace the manual exhaust valves on the two main pipes with automatic exhaust valves. The standard water collector can precisely adjust the flow of each loop, and even the flow adjustment of the deluxe standard water collector can realize artificial intelligence adjustment.
3. Functional type
In addition to all the functions of the standard type water manifold, the functional manifold also has the functions of temperature, pressure Display function, automatic flow adjustment function, automatic mixing water heat exchange function, thermal energy metering function, automatic indoor temperature control function, wireless and remote control function.
The role of the floor heating water separator
1. Adjust the temperature
The floor heating water separator is It is used for diversion. If the full water flow rate is large and the circulation is fast, the indoor temperature will be high; if the valve of each channel is half-open, or a single half-open, the amount of hot water in the pipeline will be reduced, the water circulation will be slow, and the corresponding indoor temperature will be Low; if the hot water is completely turned off, it will not circulate, which means that there is no heating in the room, so the indoor temperature can be adjusted by making good use of the floor heating water divider.
Tips: If you want to accurately control the room temperature, it is best to install a special floor heating thermostat.
2. Sub-room heating
When the floor heating system is designed and installed for large units, water pipes and return pipes will be installed in different areas, and each water pipe corresponds to one channel. Water divider, when there is no one in an area for a long time, the user can choose to turn off the water divider to achieve the purpose of room heating.
3. Diversion and voltage regulation
The water divider can divide the water in the water pipe, so that each water pipe can achieve the effect of pressure balance. There are corresponding valves for the inlet and outlet water, which can adjust the size of the water flow and achieve the balance of the water flow.
The most reasonable way to choose the floor heating water divider
The number of floor heating water dividers is not as much as possible. aspect decision.
For example, an ordinary house with an area of about 100 square meters adopts central heating, and 6-8 channels of water distributors are more suitable; reduce.
Quality identification of the floor heating water separator
1. Weigh the weight of the floor heating water separator: The weight is enough to indicate that its raw materials are sufficient, especially the brass water separator. If the weight is too light, It means that it is not made of copper, and users must choose carefully.
2. Consulting manufacturing technology: The manufacturing process of the floor heating water separator is a necessary link to ensure the quality of the floor heating water separator. If it is found that the workmanship of the water separator is rough and the cleanliness of the surface is not in place, the user should consult the process carefully and make a decision after understanding it clearly.
3. Observe the wall thickness of the floor heating water separator: The thickness of the outer wall of the floor heating water separator is the key to the quality and durability. The thicker the diverter wall, the longer the life and the more durable.
4. Multi-party comparison of after-sales service of water separators: The after-sales warranty of regular and big-name floor heating water separators is guaranteed. On the one hand, it is out of responsibility for customers. On the other hand, manufacturers have confidence and responsibility for their own brands. Therefore, users should compare and consider carefully.
What material is good for the floor heating water distributor
In order to prevent corrosion, the water collector is generally made of corrosion-resistant metal or synthetic material. Commonly used materials are copper, stainless steel, nickel-plated copper, nickel-plated alloys, and high-temperature plastics.
The stainless steel material of the floor heating water divider has the longest service life, followed by the copper material, the aluminum material has a shorter service life, the plastic water divider is fast in construction, and there are many aluminum water dividers used in the project.
Floor heating water separator installation Installation location
1. Multiple locations can be selected: As long as the design is reasonable, many locations Floor heating water dividers can be installed, such as bathrooms, kitchen balconies, etc.
2. Best location: It is generally installed on the wall below the wall-hung boiler, which is easy to operate and easy to discharge.
Installation requirements
1. The water separator is installed on the wall and in a special box, usually in the kitchen.
2. The valve below the water collector should be installed horizontally above 30cm from the floor.
3. The water supply valve is installed in front of the water distributor, and the return valve is installed behind the water collector.
4. The filter is installed in front of the water separator.
Installation steps
1. Connect the water inlet and outlet: First, connect the water inlet and outlet of each loop heating pipe to the water distributor and the water collector respectively.
2. Corresponding installation of valves: On the water supply connection pipeline before the water distributor, valves, filters and drain pipes should be installed in the direction of water flow.
3. Bypass: A bypass pipe should be set between the main water inlet pipe of the water distributor and the main water outlet pipe of the water collector. valve.
4. Set manual or automatic exhaust valve: Manual or automatic exhaust valve should be set on water distributor and water collector, and automatic exhaust valve should be installed as far as possible.
The first use of the floor heating water separator
The picture of the floor heating water separator
1. The first time Slow switch: When the installed floor heating starts for the first time, it is necessary to open the water supply valve on the floor heating sub-catchment. The horizontal state is on, and the vertical state is the watch off. At this time, pay attention to the slow opening speed. If you open it directly, there will be leakage in the sub-catchment, and the hot water will flow out directly, which is dangerous.
2. Exhaust when debugging for the first time: Same as the radiator, the installed floor heating pipes will have a lot of air. It is difficult to achieve normal heat dissipation if it is not smooth. It is very important to debug the exhaust in time. Close all valves before exhausting and exhaust them one by one.
How to use the floor heating water divider
1. The water divider can control the water supply flow of each room or area by branch. For example, if any one of the rotary core valves on the water divider is closed by half, this water channel will be heated. The temperature of the room will decrease.
2. The manual exhaust valve on the water distributor, if the heating is not smooth and the air is blocked in winter, the user can use the exhaust device to manually exhaust the air in the floor heating pipeline. Make sure that the hot water circulates properly.
3. There is a filter on the front end of the water separator. During the heating period every year, the user regularly or irregularly removes the filter screen at the lower end of the filter, cleans it, and installs it to ensure the cleanliness of the water pipe. After heating, the pipe network should be flushed with clean water.
4. If you are away from home for a long time, the main valve of the water separator can be used to reduce the circulating water volume, and it must not be completely closed. If the room is not heated throughout the winter, the water in the pipe should be drained.
How to exhaust the floor heating water distributor
First prepare a water discharge pipe and water container; find the water inlet pipe and water outlet pipe, close the valve, then open the water valve of each water distribution pipe, and rotate it to 90 degrees. Begin to deflate; gas will be discharged at the beginning, and when water flows out, close the deflation valve. The editor of Buyou.com reminds everyone that because the first release is turbid, you need to find a water container to pack it to prevent it from flowing to the ground and affecting the home environment.
What should I do if the floor heating water distributor leaks?
If the floor heating water distributor leaks, it is recommended to improve the structural design of the sub water collector, improve the connection between the sub water collector and the system, and select appropriate sealing materials. a way to solve it.
The geothermal water separator should be replaced every few years
The service life of most geothermal water separators is about 10 years, which means that it needs to be replaced every 10 years, but the specific situation depends on the water Quality, if the water quality is relatively poor, then it needs to be replaced every 7 years or so.
