I. Is the radiator remodeled well?
If your home is an independent heating system, as long as your home uses a uniform radiator, you don’t need to consider other homes. But now most consumers are central heating systems, in this case it is best not to replace the radiator at will. Not to mention that, for the sake of cheapness and beauty, different functional areas use radiators of different materials, so that there is a situation in which radiators of different materials such as iron, copper, steel, and aluminum are mixed in a family. This kind of mixed radiator is most likely to cause hidden dangers.
According to the activity of the electronic order, the corrosion resistance of steel or aluminum radiators is much lower than that of cast iron radiators, and they have stricter water quality requirements. If the original iron radiators are still used, The heating system is likely to cause the new radiator to corrode or destroy the original balance of the system.
Nowadays, the collective heating is mostly an upper-split system, and the heat source starts from the top and goes down, so the material, quantity and heat of the heating have certain regulations. If you have transformed the radiator into a complex , or adding too many slices, may cause the system to be unbalanced, leaving the heat that would have continued downstairs in your home, your home is warm, but the downstairs is even colder.
Second, radiator renovation considerations
1, the location of the radiator
p>
A radiator is not installed in any position to perform its best function. If you want to achieve the best heating effect, it should be installed under the window of the outer wall. If it is a floor-to-ceiling window, it can also be installed on the wall before the window and the window. Generally speaking, the heating effect will be relatively good in the place close to the outer wall.
2, replacement construction
During the construction of replacing the radiator, we must pay attention to the place where there is no water leakage. In general construction, workers will reserve valves on the pipeline when replacing the radiator. After the installation is completed, the stamping test must be carried out to prove that there is no leaking place before it can be connected with the original heating pipe. Considering the difficulty of construction, you’d better 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.
3The material of the radiator
Mixing radiators of various materials can cause malfunction. The living room and bedroom are made of good materials, and the kitchen and bathroom space are made of general materials. This approach seems to be light and heavy. It saves some money, but it will cause heating hazards. Experts clearly stated that installing heat sinks of different materials in the same system may damage the inner surface of the light radiator or destroy the protective layer; in addition, due to equipment changes, there are hidden dangers of malfunction.
4, pipe changes
Some consumers think the original iron pipes are ugly and plan to replace them with the heating. If you have such a plan, you can buy aluminum-plastic pipes with good appearance and better quality to replace the original heating pipes. At present, there is a new type of pipe with stainless steel texture on the market, which can also be matched with the new type of steel radiator.
3. Is it good to change the radiator to floor heating?
1. The working principle of radiator and floor heating is different
The heating principle of the radiator and floor heating is different. The working principle of the radiator is that the water is heated by the wall-hung boiler first, and then the hot water is transported to the radiator through the pipeline, and finally the heat is dissipated into the air through the radiator. to increase the indoor temperature and achieve the purpose of heating. The working principle of floor heating is to provide low-temperature hot water through the wall-hung boiler. When the hot water passes through the heating tube, the heat energy is transferred to the radiant panel through the tube wall, and then the surface of the radiant panel forms a radiation surface with a certain width and a certain temperature. way to dissipate heat evenly into the air from bottom to top.
2. Different design requirements for radiators and floor heating
Due to the different installation design requirements for radiators and floor heating, there will be some problems during the modification process . Under normal circumstances, floor heating installation requires low temperature and large flow, while radiator is high temperature, and the flow requirements are relatively low. Therefore, the high temperature and low flow pipes used by the radiator are not suitable for the use of floor heating. In addition, when designing the indoor heating pipe network, the heating pipe network entering the room should be twice the pipe network when using radiators. Of course, once there is a problem with the pipes or the pipe network during the use of the floor heating, it is very inconvenient to maintain and may damage the floor for re-installation.
3. Problems with the use of the fireplace
Although the heating Both the radiator and the floor heating should use the wall-hung furnace. However, the materials used for the radiator and the floor heating pipeline interface are different. When refitting, a conversion joint is required, and an interface cannot be directly made in the middle like some decoration companies. Once the interface is connected If there is damage, there will be water leakage. In addition, some users use domestic hot water while using wall-hung boilers for heating, resulting in insufficient supply of hot water, resulting in unheated floor heating.
Fourth, the radiator is changed to the floor heating condition
1. The house height
The heating is changed to the floor heating The net height of the house should also be considered. Usually the floor height occupied by traditional floor heating is about 6-8cm, which will affect the height of the indoor space; in addition, pay attention to whether the opening of the indoor door is affected. If the floor height is too high, it will lead to indoor space. The door cannot be opened, so it is most important to measure the clear height of the house and design a reasonable heating scheme before installing floor heating.
2. Operating temperature
Floor heating is operated at low temperature, generally controlled at 40-60 ℃, while the heating system is operated at high temperature, and the temperature of hot water supply is 60-90 , to change the heating to floor heating, a water mixing device must be installed to control the water temperature of the heating system to the temperature required by the floor heating, and the pipes must have high temperature resistance, otherwise it is easy to bake the floor heating system at high temperatures for a long time. Accidents and water leakage are common phenomena.
3. The floor is heat-resistant
There is no high temperature requirement for the indoor paved floor where the radiator is installed, but the choice of the floor heating floor has certain requirements. Require. Floor heating achieves the purpose of heating through floor heat conduction. The requirements for floor heating floor selection should not be afraid of humid environment, formaldehyde emission should not exceed the standard, heat transfer should be fast, and heat resistance should be better.
4. Construction team
Some people don’t pay attention to changing the heating to floor heating, and randomly find installation companies in the market for construction and installation, but they do It is easy to bring a lot of hidden dangers and troubles to the later use. Therefore, it is suggested that all users must choose a professionally qualified HVAC construction team, because the laying of floor heating requires a lot of research on the technology and experience of the construction party.
V. Instructions for changing the radiator to floor heating
The radiator and floor heating are completely different heating pipe network structures. The reason is that radiators require high temperature and low flow, while floor heating requires low temperature and large flow. If the heating water with high temperature and low flow for a long time will cause damage to the floor heating pipe network, this will lead to problems with the floor heating pipeline. However, the maintenance of floor heating is also more troublesome. big impact.
Secondly, the requirement of floor height of the house should be considered when the radiator is changed to floor heating. If the floor height is too low, after the floor heating is changed, people’s indoor activities will be restricted, which will affect the normal life rules and indoor space ( The floor heating is 6-8CM high), and even the inner door has to be remodeled.
From an installation point of view, radiators are suitable for any room type, such as old houses, new houses that have been renovated, rough houses, etc., while floor heating is only suitable for unrenovated rough houses, because the installation of floor heating is complicated and needs to be leveled The ground is also backfilled, and these also need to be coordinated with the decoration. If there is no such condition to change to floor heating without authorization, be careful not worth the loss.
From the point of view of heating, the original indoor radiator system has been scientifically and rationally designed. If it is changed to floor heating, it will easily lead to an imbalance in the heating system and affect the normal heating of oneself and other residents. Of course, These conditions are stipulated, and it is not allowed to modify the heating pipes and heating systems without authorization, such as installing a drain valve, exhaust valve, or increasing the number of radiators, pipes, and so on. Once the heating problem is caused by private renovation, all losses will be borne by individuals.
