Let me put it briefly: floor heating is widely used in Korean and Japanese countries with higher latitudes, and in northern China. At present, floor heating products in Korea are relatively good (I don't care, I don't want bricks). Germany and Norway in Europe have also done well.
Floor heating currently includes electric floor heating and circulation system.
There are several different ways of electric floor heating: heating cable, heating film and so-called "carbon crystal" products. In fact, the essence is to use metal or carbon to have resistance, which will heat up after being electrified. At present, there are many applications of heating cables and electrothermal films, and now many companies are making "carbon crystals". However, the industry has many questions about its service life.
Hydronic systems is a small boiler (usually burning gas, but also relying on electric heating), which heats water and circulates it through special pipes (PERT pipes are widely used) to heat water.
Circulating system and electric floor heating have their own advantages. Electric floor heating saves trouble, but the electricity bill is slightly higher; The liquid circulation system must be well sealed when installed, and the later cost is low.
2. What are the precautions for installing the circulation system?
1。
Try to match it with marble or floor. If you choose wooden floor, you can only choose composite floor, not solid wood floor.
The wood floor has good thermal stability and low moisture content, and the floor is not easy to deform after heating; The floor size is easy to be thin but not thick, narrow and not wide to meet the requirements of deformation resistance and conductivity; The mat selected for the floor is not easy to be too thick, but should be conducive to heat exchange and conduction. Be sure to choose the floor with less harmful substances such as formaldehyde to avoid the floor from releasing more pollutants due to baking, which is harmful to health.
2。 Try not to do large-scale decoration (such as carpets, etc.). ) On the floor.
Restless legless furniture, so as not to reduce the effective heat dissipation area and the flow of hot air, thus weakening the thermal effect. 3。
Ordinary foamed plastic products are not placed on the floor. Because of the poor thermal conductivity of these articles, it is easy to cause heat accumulation, and it is easy to produce harmful gases under the action of long-term high temperature, which is harmful to the health of residents.
4。 When the floor heating system is turned on, the temperature should be raised slowly, preferably about 65438 0℃ for one hour.
Keep the floor clean and dry before heating to prevent cracking and deformation due to excessive heating. 5。
Do not bump, knock or wedge into any sharp objects on the ground. The floor heating pipe laid under the ground is only about 3-4cm away from the floor, so it is easy to hurt the floor heating pipe if you are not careful.
6。 The water supply temperature is not easy to be too high.
Because the floor heating system belongs to low-temperature radiation heating mode, the water supply temperature is not easy to exceed 60℃, and the working pressure of the heating system is not easy to exceed, otherwise it will not only cause the problem of uncomfortable heating, but also seriously reduce the service life of the whole system. In this regard, consumers can also choose some automatic control system devices, that is, floor heating mixed water cooling system.
Just use a thermostat to control the heating. .
3. Precautions for installing circulating system
According to the experience of floor heating sunshine heating company, because the installation power of general home improvement companies is relatively weak, users know little about the basic knowledge of home improvement, so there will always be many hidden dangers after home improvement, which will bring a lot of trouble to users. Let's talk about these issues: 1. Water supply and drainage.
The water supply and drainage of the floor heating and sunshine heating company includes the water and drainage facilities in the bathroom and kitchen. Generally speaking, in the process of decoration, the equipment in the kitchen and bathroom will often be displaced and replaced. When replacing the water supply pipe during construction, attention should be paid to setting the water meter in a place that is easy to see and maintain, and placing it horizontally. The valve is preferably made of copper cut-off valve. When installing, attention should be paid to the reliability of pipeline installation and fixation, and the thickness of decorative surface should be considered, so that the clear distance between pipeline and wall should be controlled at about 20mm to facilitate the maintenance and disassembly of pipeline in the future, and the water supply pipeline should not be buried in the dark. The consequence is that it is difficult to maintain and the decorative surface must be destroyed. When the water supply pipeline passes through the hall, room or hanging cabinet, a dewproof layer should be added, and the hot water pipe should be insulated.

4. What is a circulatory system?
Floor heating is short for radiant floor heating, and English is radiant floor heating. It takes the whole floor as the radiator, heats the whole floor evenly through the heat medium in the radiant layer of the floor, and conducts it from bottom to top by using the law that the floor itself accumulates heat and radiates upwards, thus achieving the purpose of heating.
Water heating system refers to a heating method that heats water to a certain temperature, transports it to the water pipe cooling network under the floor, and realizes the heating purpose through floor heating. The low-temperature geothermal medium forms a gradually decreasing temperature gradient from the sole of the foot to the head indoors, which gives people the comfort of warming their feet and cooling their heads.
Radiant floor heating conforms to the fitness theory of "warm feet and cool roof" in traditional Chinese medicine. It is the most comfortable heating method at present and a symbol of modern life quality.
