Home heating line renovation problem, heating renovation needs to pay attention

Parallel connection in the same trip is the best! Each group of heaters can be turned on and off individually and at the same temperature!

The characteristics of single-tube series connection are low material usage, relatively weak labor intensity, and shorter transformation time. The water of the whole system passes through the first set of radiators of the system, then the second group, then the third group ......, so the water temperature is gradually decreasing in the order of series. Under the same conditions, the temperature of the first and last two sets of heaters can be more than 2 degrees different!

The characteristics of double-pipe cross-path parallel connection are that the pipeline stroke is short, each group of radiators can be controlled separately (the inlet and return water inlet and return at the front end of the radiator add a control valve), the temperature is relatively uniform, and the water flow balance of the system will be greatly improved compared with the single-pipe series, but this system still has certain limitations. The water flow rate of each group of radiators is different, and the return water of the front-end radiator is relatively fast because it is closer to the main pipeline, while the backwater return at the rear end is slower, which may cause the phenomenon that the end heating is not hot or not hot enough.

Double-tube co-accord parallel, also known as twin-tube co-trip. The characteristics are basically the same as the two-tube asynchronous parallel. However, there is a difference in the operating principle, simply put, it is called first supply and then return, that is, the return water of the first group of radiators at the front end does not circulate to the main pipeline temporarily, but continues to go down, connect the return pipe of the next group of radiators, and so on....Pull a return line from the radiator at the very end and return it to the return pipe of the main pipe.

The water flow rate of each set of radiators in the system is basically the same, and the system is very balanced, and there is generally no phenomenon of no heat at the end. It can be said that it is the best way to balance the hydraulic system!

The two-way cycle is convenient for controlling the heating temperature and future maintenance, but the upfront investment is large. There is no need to install a water separator for the double circuit, and it is very convenient to add a valve to each group of heating water supply and return water.

There is no need to repeat the tandem. Another advantage of dual circuit is that if a pipeline has a problem, it can be changed to a series connection.

<> "Heating renovation needs attention.

Collective heating in the north is generally divided into two types: floor heating and heating, the old community is mainly heated, and the new community is mainly ground heating. Both have their pros and cons, and some owners will remodel them to meet their individual needs. Heating to underfloor heating.

1. The heating coil should be considered for different heating temperatures.

The question of longevity. The water temperature of floor heating is generally below 60, while the water supply and return temperature of heating is 95-70, which is very different. If the entire residential area is heated by heating, then the overheated water temperature must be considered when renovating, which will affect the service life of the coil.

Solution: Before entering the floor heating, follow the inlet and return water heat exchanger, the principle is to exchange high temperature water into low temperature water. Remember not to direct hot water to the coil.

2. Different resistance needs to be considered.

The resistance of floor heating is about ten times more than that of heating, and if you don't consider the resistance problem and blindly transform, the lack of pressure in the heating system and the circulation of the support coil will eventually affect the heating supply. Solution: Add a water mixing thermostat device to force water circulation through a circulating pump.

Heating to underfloor heating.

3. Floor issues need to be considered.

Changing heating to floor heating will generally increase the height of 6-8 cm, and it is necessary to consider whether it will have an impact on life after the transformation. Solution: Dig a few more centimeters of ground.

4. The thermal conductivity effect of floor tiling needs to be considered.

Heating is changed to floor heating, and heat conduction has also become a way for ground radiation heat dissipation, so the material of the ground will have a certain impact on the thermal conductivity effect, which needs to be considered before transformation. Underfloor heating to heating.

There are not many floor heating to heating, the main reason is that the heating effect will be reduced, especially the whole community is quietly floor heating. The solution is: add as many radiator groups as possible, increase the circulation pump to increase the circulation speed of water.

There are not many underfloor heating to heating, and more consideration needs to be given to the heating effect.

No matter what kind of renovation, it is part of the thermal transformation, and finally communicate with the property and heating company, and then implement it after obtaining permission.

The design of the heating system focuses on the heating pipes of the radiators. The heating system heating pipes are the places that affect the decoration of the house seriously. Therefore, the design of the heating system focuses on the setting of heating pipes, so let's follow the golden flagship to learn about it.

The heating system is designed with a focus on the heating pipes.

Heating duct alterations.

Aluminum-plastic pipes are the first choice: some consumers find the original iron pipes unsightly and plan to replace them with the heating. If you have such a plan, you can buy beautiful and good quality aluminum-plastic pipes to replace the original heating pipes.

At present, there is a new type of pipe on the market with a stainless steel appearance, which can also be used with a new type of steel heating. Replacement construction: Safe containment is key.

In the construction of replacing radiators, it is necessary to pay attention to the places where there are no water leaks. In general construction, workers will reserve valves on the pipes when replacing radiators. After the installation is completed, it must be tested by stamping to prove that there is no place for running and dripping, and then it can be connected to the original heating pipe.

Considering the difficulty of construction, please do not change the position of the heating riser. Because of this, the workers have to go to the neighbor's house for construction, which is very inconvenient.

Heating piping is set up with ** factor.

Save money by living within your means: The new type of radiator is expensive, with an average of 105 yuan to 260 yuan per piece. If you replace all 5 sets of heating in a two-bedroom apartment, it will cost about 5,000 yuan to 6,000 yuan.

Therefore, it is good to minimize the use of radiators without affecting the indoor heating effect in order to achieve the best"Performance** ratio"。

How heating lines work.

There are usually two kinds of heating: water heating and gas heating, the general heating pipe refers to water heating, which is to use a wall-hung boiler or boiler to heat circulating water, and then link to the heating pipe through the pipe, and finally output the appropriate temperature through the heating pipe to form an indoor temperature difference, and then carry out thermal circulation to make the entire indoor temperature rise uniformly. The air heating is to heat the air, the cold air is heated into hot air by the heating pipe as soon as it comes in, the hot air rises and forms a convection with the cold air of the house, and the cold air circulates to the vicinity of the heating to be heated into hot air, and the hot air circulates in the house, and the room is warm.

The working principle of the heating pipe is to transform the original heating pipe cavity into an independent circulation system, adding a small amount of superconducting liquid to it, and only taking water in the connecting pipe at the bottom of the heating pipe. When the water flows in the connecting pipe of the superconducting heating pipe, the superconducting liquid is used as the medium to transfer heat, and the superconducting liquid is heated to cause the molecules and atoms of the substance to collide and rub with each other to produce heat energy, resulting in the phenomenon of aggregation and fusion, so that the superconducting medium is instantly heated at high speed, and the activated and gasified high-temperature gas radiates outward through the surface of the heating pipe to dissipate heat. At the same time, it is condensed and flows back to the heat source duct, where it is activated for vaporization.

Work repeatedly to achieve the purpose of energy saving and heat dissipation.

Clause. 1. Have you really modified it yourself? If you haven't modified it, you can find the other party with confidence, but the tone should be calm and the problem will be solved.

If you have modified it yourself, you also have the possibility of losing two kinds of gods. First, the effect after modification should be better than before the modification, so it is not a problem of modification or not, it may be that the external network system is not good, resulting in the effect of the whole building is not good. Second, after the modification, due to the poor level of the modified personnel, the effect after the modification is not as good as before.

If it's the latter, you have to find him to help you find out the reason, adjust the symptoms and change it.

The main reasons for the lack of heating are as follows, and you can also analyze and analyze them yourself:

1. The system design is unreasonable, such as poor exhaust and gas accumulation points, resulting in air locks, and the water crossing section is reduced but not hot.

2. The system is aging, there is too much mud accumulation in the pipeline, the resistance increases, and the flow rate of the water crossing section is absolutely reduced but not hot.

3. The external network conditions are not good, and the inlet and return water pressure difference is too small.

3. The heating temperature of the external network is low, which does not meet the needs of users.

Other reasons.

It depends on what kind of heating you have, adding equipment or pipes without increasing the power of the heating should not be considered a private transformation.

Moving the heater or increasing the radiator is considered a heating remodel, and it is best to find a helper from the company to take a look.

Now it is autumn, many families will choose to install heating to increase the indoor temperature in winter, replacement and installation of radiators has become a basic skill that some families should master, although the installation and more slippery radiators are not a very technical work, but if you want to transform the heating you need to know some precautions, today I will introduce to you the analysis of the key points of the transformation of heating, to give you a safety premise.

1. The time to deal with the heating.

It should be changed as soon as possible before the wall treatment, otherwise it is easy to destroy the wall that has been treated, and make the wall unsightly, and you also need to find a master to come and refill the wall, which is more troublesome.

Second, the content of the processing.

The main thing is to dismantle the original heating, dispose of the original old water pipe, generally cut off, and then adjust the direction of the pipe according to the position of the heating, and install two valves. The rest of the treatment is after the wall treatment is completed.

3. Design location before transformation.

Before the heating transformation, you need to design the location by yourself and pay attention to the height: for the heating, counting the elbows at both ends, the height of the heating and the ground is 20cm, so it is about the total height.

Fourth, heating transformation.

If you want to change the direction of the heat, you may have to trouble the downstairs neighbor to fix the heating pipe with a pipe wrench, and then unscrew the elbow above the sock leak to change the direction of the elbow.
