Water heating and heating cables are used for paving cement. Generally, the installation time is 3-4 days. The project needs to be more detailed. Because once the heat is broken, the repair is troublesome.
Heating in winter has been a few days, and heating installation has become the most important part of the renovation process. Traditional radiators and air conditioners use hot air convection to regulate indoor temperature. Radiant floor heating, on the other hand, utilizes a pipe system buried under the floor to radiate heat into the room to gradually increase the room temperature.
At present, there are two ways for floor heating: one is to bury water pipes and the other is to bury heating cables. Embedding water coils is one of the most used methods in China. At present, it is probably five or six years before China warms up to enter the country. The market is not standardized. Therefore, there are many problems. Most of them are unable to meet the heating standards because some manufacturers do not have good results. However, the reporter recently learned from the Internet that the “Detailed Rules for Floor Heating†will be formulated by the Air Conditioning Institute of the Ministry of Construction of the People's Republic of China, and will be introduced in April next year. By then, there will be new standards for floor heating, and it will be even more likely to enter millions of households.
The construction of the floor radiant heating system should be carried out separately. Therefore, users who want to use floor heating must first let the floor heating company communicate with the decoration company in advance to coordinate the work process.
Ensure the construction of hydropower pipelines before construction
Before installing the floor heating system, ensure that the construction of the hydropower pipeline on the construction site is completed; the kitchen and toilet shall be closed and tested after acceptance; the construction area shall be level and clean and there shall be no equipment, materials, or debris that will affect the construction.
About 120 square meters of flat house, the floor heating construction period is generally three or four days, for the control system requires a higher level of jump units, the construction period takes about a week. Before installing the floor heating, gradually increase the temperature of the concrete floor by 5°C per day until it reaches the standard of about 18°C.
Manual knob thermostat is easy to operate
The floor heating system uses a temperature control system for temperature regulation. Leveling units are generally equipped with a temperature control device in the living room or master bedroom. The temperature controller directly adjusts the boiler feed water temperature according to the room temperature and temperature settings. The temperature of each room in the operation rises with the same rise. Leap-level units mostly use zonal control, and generally separate water separators are installed on each floor to regulate the temperature of the floor where the floor temperature rises and falls.
There are a variety of thermostats, manual knob type, programmable digital liquid crystal type. The knob-type thermostat can only be manually dialed to adjust the temperature. The floor heating system has good thermal stability. When the temperature is found to be high or low, manual adjustment is required. It takes several hours to achieve indoor temperature adjustment. However, this is generally used today. Ways.
Use regular products to sign maintenance guarantee
At present, the floor heating market is very non-standard, and floor heating products vary greatly. Therefore, it is necessary to select experienced professional heating companies and high-performance products. Floor heating is a systematic project. The experienced ground heating company can select various insulation materials and control systems according to the structure, orientation and layout of the user's room. Standard pipes used for floor heating systems have a design life of up to 70 years and an actual life of 30-50 years.
In addition, we must pay attention to the signing of maintenance guarantees, because the use of floor heating pipes after 3-5 years will require the removal of scale in the pipeline. This is not something that ordinary families can do, and it requires specialized companies to build. However, the current domestic heating company equipment can not reach, do not take the initiative to mention warranty issues when doing floor heating.

Choose professional flooring and floor mats
Floor heating system engineering is mainly buried in the underground pipe, communicated to the floor through the pipe temperature, and then raise the indoor temperature. The floor heating project generally needs to be equipped with underground pipes, boilers, water separators and other major accessories, which are provided by the floor heating company. Many new home developers have boilers and equipment rooms. Floor heating companies need to check whether the boilers provided in the rooms can be used for floor heating. If not, they need to provide a boiler, and the safety and location of the boiler should be considered.
Water temperature must be controlled at 30°C-50°C
If the district is a centralized heating, the hot water supply temperature is 60-90°C. If the direct connection to the floor heating system is obviously overheated, not only will the human body feel uncomfortably caused by the high surface temperature, but the life of the floor heating system will also be reduced. Generally, the floor heating system can only be used after controlling the water temperature of the floor heating system to the required temperature of 30°C to 50°C.
Pay attention to insulation before installing pipeline
If there is a protective layer in the room's cement, the tank can be directly grooved on the concrete floor, but now it is seldom allowed to slot directly on the ground. Generally, the pipe should be directly added to the ground and then leveled with cement mortar. Before installing the geothermal pipes, it is necessary to lay a layer of plastic on the ground and then add a layer of tin foil. The purpose of this is to keep warm and let the heat rise instead of passing underground or downstairs. Then bury the tube directly and add cement mortar to level it.
Floor heat is good and should not be thick
For homes that have been warmed to the floor, when choosing materials for the ground, we must pay attention to the principle of not being thick, suitable for environmental protection, and good heat resistance. Can not lay the keel of solid wood flooring, because many keels need to nail the nails on the ground, which will undermine the pipeline heating. At present, there is a special warm wooden floor, which can be used at home by using a buckle. Floor materials generally use floor tiles, solid wood composite flooring or reinforced composite flooring, but solid wood composite flooring has good resistance to deformation, and reinforced laminate flooring has good heat dissipation performance and needs to be selected according to individual needs.
It is best to use a small size for flooring, so that the resistance to deformation will be better. The baseboard should not be installed at the same time as the floor. It must be installed after the floor glue is completely dry to prevent deformation. To use geothermal special paper mats, such mats have characteristics of fast heat conduction, no deformation, etc., and cannot use ordinary foam mats. Foam mats have low thermal conductivity, and they are prone to produce harmful gases for a long time under the effect of high temperatures and endanger consumers. Health.
Expert experience
Do not place glassware directly on the ground
â— Yang Jia, male, 27 years old, model my home used underground heating 5 years ago. It was just for the sake of good looking. Later, it was found that floor heating is indeed better than ordinary radiators. It can actually be used more than ordinary heating because it's It takes a long time for the temperature to rise and fall, fearing to damage the floor.
Last year I bought a large fish tank to raise fish. When I was warming up in the winter, I suddenly heard a muffled and burst of the fish tank. Later, he asked us to install a warm company, people said that the beginning of heating in winter, because of uneven heating, thermal expansion and contraction, will open, so it is best not to place water directly on the ground glassware and porcelain.
Professional reminder
Long-term high temperature requires timely humidification
Raised floor heating after floor heating
After generally warming, the ground will inevitably increase. The pipe needs 8cm in height, and then add solid wood floor, floor tiles, stone, and backfill layer. The occupancy of the room can be reduced to 2cm-4cm. Therefore, if the user of the room is too low, he will feel lower height and feel depressed after using floor heating.
The floor is eco-friendly
In the international standards, there are very strict requirements on the moisture content of the floor, thermal stability, formaldehyde release standards, but the special floor for geothermal heating must be selected for environmental health, because the surface temperature of the floor heating system is high, if the floor is not Qualified, it is possible to produce gases that are harmful to the body through heating.
Switch to warm slowly
During the initial operation, the water temperature is first controlled within the range of 25°C to 30°C for 24 hours, and then every 24 hours, the temperature is raised from 5°C to 10°C until the water supply temperature reaches the design temperature. If you heat up too quickly, the floor may crack and twist due to expansion. When it is no longer necessary to heat the geothermal system indoors, it should be noted that there must be a process to turn off the geothermal system. The cooling process of the floor must also be gradual and not drastically reduced.
Surface temperature should not be too high
With geothermal heating, the surface temperature should not exceed 28°C, and the temperature of the water pipes should not exceed 45°C. When the winter floor is exposed to high temperatures for a long period of time, it is necessary to humidify the room in order to prevent the floor from cracking and deforming. Try not to fix the decoration on the floor and put legged furniture, otherwise the furniture will be easily deformed and cracked.
