Why doesn t the state recommend underfloor heating?

First, the construction of the project is more complicated.

Installing underfloor heating is not as simple as installing heating. In the initial stage, it is not only necessary to level the ground, but also to do coiling, fixing, backfilling and other engineering construction. And the slightest carelessness in the construction of these projects can lead to many problems.

The overall construction process of the project is more complicated, and the construction time of the project is relatively long, for friends who want to install the house as soon as possible, it will become relatively troublesome to do floor heating.

Second, the later maintenance troubles.

Unlike heating, floor heating is directly installed in the room, so if there is a problem, it is very troublesome to repair, and it is relatively troublesome to repair it later. It will also leave some traces of repair, which will affect the aesthetics of the room.

Three, ** high.

First of all, the cost of natural gas, water and electricity bills necessary for laying underfloor heating every year will not be lower than that of other heating equipment. In addition, because the construction of the project is more complicated, its labor cost is relatively high. In addition, the underfloor heating material is measured according to the area in the room, so the larger the area, the more material costs are used.

In addition, the total cost of on-time maintenance and cleaning will be relatively high.

Floor heating is not recommended, mainly considering that there are the following types of disadvantages of floor heating:

1) Complex installation.

The pre-installation work of floor heating is very complicated, not only to carry out the ground, but also to do coiling, fixing, backfilling and so on.

2) Accelerate formaldehyde release.

Floor heating is installed under the floor or tile, and the wooden floor contains formaldehyde, isocyanate and other harmful substances, in the geothermal environment, the formaldehyde volatilization rate of the wooden floor will increase exponentially with the rise of temperature, increasing the release of harmful substances, accelerating the release of formaldehyde.

3) Lower the height of the house.

The floor heating pipe has a certain thickness, and the thickness of the cement and sand after leveling will be added later, which will occupy some of the indoor space in the room and increase the height of the house, which is not friendly to low-rise apartments.

Second, the old house should not be easily changed to floor heating.

1. The construction of floor heating is more complicated, and there are certain requirements for the structure of the house, so the premise of changing the floor heating of the old house is to find a professional and standardized HVAC company, with design specifications and reasonable configuration, and the underground pipeline part is tested for injection pressure after the installation is completed, so as to ensure safety. Many people say that old houses should not be easily changed to floor heating, which is the reason.

2. The structure of the general old house and the thickness of the wall are designed according to the previous building standards, and the sealing effect is not very good. Once you want to change the floor heating, there are more things to consider, and it is easy to have uneven heat dissipation in the later stage, which affects the heating effect.

3. Old houses generally use traditional central heating. Therefore, if the installation of floor heating should be coordinated with the local heating company, the reasonable design of the heating pipeline, if the independent heating is adopted, but also according to the design of the floor heating to choose the appropriate power of the wall-hung boiler, is a more complex process, so it is recommended not to easily change to floor heating.

Generally speaking, most of the floor heating will use wooden floors or tiles as the floor materials, and the wooden floors contain formaldehyde, isocyanates and other harmful substances, in the geothermal environment, the formaldehyde volatilization rate of the wooden floor will increase exponentially with the rise of temperature, thereby endangering the health of users. Tiles are also radioactive, which carries the risk of causing cancer or other diseases.

First, floor heating takes a long time.

The underfloor heating pipes are buried in the ground, and a layer of cement is laid around the perimeter. After the heating system is turned on in winter, the surrounding cement and sand will heat up first, and then the temperature will be transmitted to the ground, and the indoor temperature can gradually rise.

Second, the cost of maintenance is high.

After a few years of floor heating, the heating effect will be greatly reduced, this is because the cleanliness of the heating water is not high, and the impurities contained in it are attached to the inner wall of the pipe, which will directly affect the heating effect, some netizens in order to save money, will use the chemicals purchased online to clean the heating pipe, which will seriously corrode the pipeline, resulting in the rupture of the pipeline, in case of failure of the floor heating pipe, the fault location cannot be accurately judged, and the ground needs to be pried open to check one by one, the maintenance cost is high and seriously affects the normal residential life, in order to extend the service life of the pipeline as much as possible, To ensure the heating effect, the owner can only ask professionals to repair and maintain it every other year, which is also a large expense for many years.

Third, water leaks are not easy to detect.

If the heating pipe is not regularly maintained, it will inevitably fail in disrepair, but the floor heating pipe is buried in the ground, and the water is infiltrated downward, and it is not easy to be detected when leaking.

Fourth, it will occupy the height of the floor.

Floor heating does not occupy the ground space, which can increase the aesthetic effect and expand the indoor activity space, but the floor heating buried in the ground will occupy 10 cm of floor height, and the higher floors have good lighting, and can also form a visual sense of emptiness; However, the lighting on the lower floors is poor, the interior is dark and damp, and after the installation of floor heating, the room appears low, which will cause a sense of depression.

The state does not recommend the use of floor heating, mainly because floor heating may produce harmful substances and endanger health in use. Generally speaking, most of the floor heating will use wooden floors or tiles as the floor material, and the wooden floor may contain formaldehyde, isocyanate and other harmful substances, in the geothermal environment, the formaldehyde volatilization rate of the wooden floor will increase exponentially with the rise of temperature, thereby endangering the health of users. Tiles are also radioactive, which carries the risk of causing cancer or other diseases.

Later maintenance is troublesome and expensive. The reasons why it is not recommended are as follows:

1. The overall construction process of the project is complex and the construction time of the project is relatively long.

2. The comfort in the heating process is relatively poor.

3. Later maintenance troubles.

4. Because the floor heating pipe has a certain thickness, plus the thickness of the cement and sand after leveling, this will occupy some indoor space in the room.

Nowadays, there are also a lot of heating methods and equipment, and many people who can't accept the shortcomings of floor heating have chosen other heating methods, such as installing radiators or air conditioners.

Beijing prohibits the installation of floor heating because it is not suitable for high temperature operation. Beijing and other big cities are using the method of urban central heating, if the high temperature of the floor heating, the service life of the floor heating is worrying. It cannot achieve energy saving and consumption reduction, and the temperature deviation between indoor and outdoor is too large for the human body, which is easy to be detrimental to health.

There are different degrees of damage to the later stage of home decoration such as floors, cabinets, wardrobes, etc. If the maintenance fails, once there is a problem, it will be destructive, don't repair it, if you want to heat, you have to go to the house to hang radiators.

Pros and cons of installing underfloor heating at home

The advantages are hygiene, health care, environmental protection, floor heating in line with the traditional Chinese medicine warm feet and cool top human body supply and demand, giving people a good feeling of warm feet and cool heads, does not cause the convection of dirty air, and the room is very clean. Good thermal stability, due to the good thermal stability of the ground layer and concrete layer, the indoor temperature changes slowly under the condition of intermittent heating, and it feels very natural.

The heat source equipment of floor heating is a gas wall-hung boiler, coupled with good usage habits, the use fee of floor heating is relatively low. It does not occupy the usable area, reduces floor noise, temperature controllability, and has a long service life.

The disadvantage is that it is assembled on site and has a large randomness. Strong thermal inertia, temperature control hysteresis, one-time molding, difficult maintenance.

The installation of floor heating has its special requirements (low temperature and large flow), and the whole of North China and Beijing and other large cities are used in the way of urban central heating, and floor heating is not suitable for high temperature operation.

As the capital of China, Beijing is a political and economic center and a megacity.

The development of industry and huge traffic flow in the urban area, the temperature in the urban area is relatively high, and the floor heating needs a low temperature and low energy consumption environment, and the urban area of Beijing is not suitable for the installation of floor heating, but the unified heating of the city, so Beijing prohibits the installation of floor heating by itself.

Requirements for the installation of underfloor heating.

1. The service life of floor heating is worrying. It cannot achieve energy saving and consumption reduction. For the human body, the temperature deviation between indoor and outdoor is too large, which is easy to be detrimental to physical health.

2. Floor heating has different degrees of damage to the later stage of home decoration (floor, cabinet, wardrobe, etc.). 5. Repair is not successful, but if there is a problem, it will be destructive (smash the ground to repair it, the floor heating is not yet floor tiles.)

It's worth it) don't fix it if it's broken, and if you want to heat it, you have to go to the house to hang radiators.

3. The inlet water temperature of floor heating is generally below 50 degrees, and the return water temperature becomes 30 degrees at home, and the temperature of the water becomes 30 degrees when you turn around at home, and you can use natural gas to burn the floor heating, a gas wall-hung boiler to burn, then no one is willing to burn to 80 degrees, and the home is not cold, but the overall heating can only run at high temperature and low flow for heating temperature and effect, and the inlet and return water of 80 degrees is 60 to 50 degrees, so you can save the time and energy of water temperature burning.

4. Some people say that floor heating can leave a lot of space at home, that is misleading, floor heating needs to occupy a distance of 6 8 cm on the ground after paving, so the floor heating not only reduces the height of the house, but also occupies 6 8 square meters in the room, spending 1800 yuan or even more than 2000 yuan per square meter to buy a house, so it wastes 6 8 square meters, so many are not allowed to install.

If there is gas blocked in the floor heating pipe, you can use the air release valve on the water separator to open the gas in the pipe and release the air until the hot water is released, so that the problem of floor heating is not hot should be solved.

If it is a non-thermal phenomenon caused by uneven circuits, the purpose of uniform circulation can be achieved by adjusting the valve.

If the floor heating is not hot caused by improper construction, this situation is not easy to solve. Therefore, it is recommended that users should select those well-known brands as soon as possible when choosing products or installation companies, and should also go to the site to supervise the installation process.

If the floor heating has not been cleaned for a long time and causes blockage, generally speaking, the floor heating pipe should be cleaned once every 3-5 years, and the user should find a professional floor heating cleaning company to complete, so that the floor heating is not hot and it will be solved.

If the temperature of the floor heating is not very good, you can find a worker who specializes in cleaning the floor heating to clean, and the cost is about 50 yuan per pipeline, and the effect is very good. It is very convenient to connect the water pump that flushes the floor heating pipe to the water pipe and the drain.

There are many ways to use heating, and the state can't force people to use only floor heating, right.

Legal analysis: The state does not recommend the use of floor heating, mainly because floor heating may produce harmful substances and endanger health in its use. Generally speaking, most of the floor heating will use wooden floors or tiles as the floor material, and the wooden floor may contain formaldehyde, isocyanate and other harmful substances, in the geothermal environment, the formaldehyde volatilization rate of the wooden floor will increase exponentially with the rise of temperature, thereby endangering the health of users.

Legal basis: "Residential Interior Decoration Management Measures" Article 5 Residential interior decoration activities, the following acts are prohibited:

A) without the original design unit or the design unit with the corresponding qualification level to put forward the design plan, change the main body of the building and load-bearing structure;

2) Changing rooms or balconies without waterproof requirements into bathrooms and kitchens;

3) Expand the size of the original doors and windows on the load-bearing wall, and remove the brick and concrete walls connecting the balconies;

4) Damage the original energy-saving facilities of the house and reduce the energy-saving effect;

5) Other behaviors that affect the safety of building structure and use.

The main body of the building in these measures refers to the structural structure of the building entity, including roofs, floors, beams, columns, supports, walls, connecting joints and foundations.

The load-bearing structure referred to in these measures refers to the main structural components and its connecting joints that are directly transmitted to the foundation with its own weight and various external forces systematically, including load-bearing walls, poles, columns, frame columns, piers, floor slabs, beams, roof trusses, suspension cables, etc.

The installation of floor heating has its special requirements (low temperature and large flow), and the whole of North China and Beijing and other large cities are used in the way of urban central heating, so the floor heating is not very suitable for high temperature operation.

Precautions for installing underfloor heating:1. Choose a professional floor heating company.

The underfloor heating is a complicated matter, and if it is not done well, it is easy to leave potential safety hazards.

Therefore, it is necessary to choose a professional floor heating company for construction. In this way, from the scheme design to the selection of products, it will be more professional, and the insulation effect will be better. Further, choose a professional floor heating company, and the after-sales service will be more professional.

2. Select a company with rich construction experience.

The most important thing to install floor heating is to have a good insulation effect, plus it is a concealed project.

Rectification and maintenance will be troublesome, so it is necessary to choose an experienced underfloor heating company. They can customize the most reasonable construction plan according to the structure and orientation of the user's house.

In this way, the heat distribution effect will also be better.
